Description

The invention relates to the field of processing or generation of image data and can be used in user interfaces of computer programs involving text input and editing.

Text input and editing can be carried out both in text editors (word processors) that work with multiline documents, and in search engines that work with only one line.

A cursor is known in the user interface - a graphical interface element that points to an object that will be interacted with using a keyboard, mouse or other control device

(https://en.wikipedia.org/wiki/%D0%9A%D1%83%D1%80%D1%81%D0%BE%D1%80, the date the information was posted in the electronic environment on 04/16/2019).

The text cursor is designed to indicate where the text entered from the keyboard will be inserted. The cursor is usually flashed so that it can be quickly found in the text - a fixed cursor can be difficult to see in a large text. The most common cursor shape in modern user interfaces is a vertical bar corresponding in height to the height of a line of text and located at the beginning of the familiar character of the input character. In some cases, other types of cursor are used: a rectangle wide in familiarity, covering the next character, an underscore, or another character. For example, in ZX-Spectrum computers, a capital Latin letter in familiarity was used as a cursor (see ibid., Prototype).

Currently, there is a strong opinion that the width of the cursor is constant and cannot exceed the width of one familiarity.

This is due to its indistinguishability in the text line and, especially, in multi-line documents, which is a disadvantage of the known methods for forming cursors. According to the applicant, the method of forming the cursor in modern text editors, for example, in ms word (https://studfile.net/preview/5170593/page:31/, the date the information was posted in the electronic environment on 02/10/2016), which consists in forming a flashing vertical bar with a width of no more than two pixels is the worst possible way.

The applicant proposes technical solutions (see independent claims No. 1, No. 2 and No. 6 of the claims) for forming a text cursor in the edit field of the user interface, united by a common inventive concept, providing the possibility of forming a text cursor with a length of more than one familiarity. Moreover, the technical solution set forth in paragraph No. 6 of the claims, allows you to create a cursor with a length of at least half the length of the edit field.

The general inventive concept also consists in the fact that the applicant proposes to make the cursor length a variable, which is in a certain functional dependence on the location of the cursor in the editing field.

The technical result of this invention is to increase the length of the text cursor to facilitate its visibility.

This technical result is achieved due to the fact that either a fixed cursor length is determined in advance, ranging from one familiarity to the maximum possible number in the edit field, which may decrease as the first border of the cursor approaches the beginning of the text input field, or the cursor length is from the very beginning, a variable that depends on the position of the first cursor border, set to the position of the desired cursor location. Some functions of this dependency are described below.

The invention is illustrated by the following graphic images:

FIG. 1 - forming a cursor according to paragraph 1 of the claims with a cursor length equal to three familiarities;

FIG. 2 - forming the cursor according to paragraph 4, in which the second border of the cursor is positioned at the beginning of the current word;

FIG. 3 - forming a cursor according to paragraph 5 of the claims, in which the second border of the cursor is placed at the beginning of the edit field;

FIG. 4 - forming a cursor according to paragraph 6 of the claims, in which the second border of the cursor is placed at the end of the edit field;

FIG. 5 - forming a cursor according to paragraph 6 of the claims, in which the second border of the cursor is placed at the beginning of the edit field.

Terms, definitions and abbreviations used in this description of the invention.

Word

A character set limited to spaces if the character set is in the middle of a line.

A character set limited to a space to the right if the character set is located at the beginning of a line.

A character set limited to a space on the left if the character set is located at the end of a line.

The character set that is unique in the string.

Edit field

A rectangle filled with the background color (usually white), and when the input focus is received, a cursor appears in it, inviting you to enter text in the field or edit it (see

https://en.wikipedia.org/wiki/%D0%A2%D0%B5%D0%BA%D1%81%D1%82%D0%BE%D0%B2%D0%BE%D0%B5_%D0 % BF% D0% BE% D0% BB% D0% B5, the date the information was posted in the electronic environment on 08/11/2018).

The edit field can have a horizontal or vertical arrangement depending on the user's use of the direction of writing.

The characters entered in the edit box are arranged sequentially one after another in positions with specific numbers. The first character is located in the first position, the second - in the second, and so on in ascending position number. In addition, the place of a symbol in the edit field can be defined as the number of pixels from the beginning of the field to the first pixel of this symbol, inclusive.

A field is not only a graphic representation of a rectangle on a computer display screen. It contains information displayed on it, which is stored in the computer's memory and can be edited by the user.

Abbreviation: “field”

Synonym: “row” or “column”

Original background color of the edit field

The color of the edit field specified by the developer of the user interface or selected by the user from a predefined list of possible options provided to the user by the developer of the user interface.

The original background color of the edit field is contrasted with the color of the characters displayed in this field.

The initial font color of the displayed text.

The font color specified by the user interface developer or selected by the user from a predefined list of possible options provided to the user by the user interface developer.

The original font color is contrasted with the background color of the edit field.

Pixel

The smallest logical element of a two-dimensional digital image in a raster graphic, or the (physical) element of a matrix of displays forming an image. A pixel is an indivisible object of a rectangular or round shape, characterized by a specific color.

Text input direction

One of the directions for entering text is from left to right, from right to left or from top to bottom.

Position of the desired cursor location

The position of the editing field in which the user wants to position the cursor by pressing one of the keyboard keys, such as “left arrow”, “right arrow”, “Delete”, “BackSpace” and so on, or using the mouse manipulator (hereinafter “Mouse”) or using another similar device.

Text cursor

In the present invention, the text cursor may be of two types.

a) An area of a rectangular shape having a background whose color is different from the original background color of the edit field and is contrasted with the font color of the displayed text.

b) The area of the rectangular shape into which the characters are displayed, with font characteristics different from their original characteristics, the totality of which form the cursor itself.

The place where the text entered from the keyboard will be inserted is determined by the location of one of the two borders of the rectangular area of the cursor (cursor borders). The cursor border, which is set to the position of the desired cursor location, will be considered the first cursor border or cursor pointer.

Shortcut: “cursor”

Since the horizontal cursor size in the present invention is overwhelmingly greater than its height, instead of the term "cursor width", which was used in the known methods of forming a text cursor, the term "cursor length" is used in this description of the invention.

Current word

The word on which the cursor (first border) is located. Font

In this description of the invention, a font with a different font characteristic will be understood to mean a font having any visually distinguishable difference (including not noted above) from the original font.

Here ends the description of terms, definitions and abbreviations used in this description of the invention.

The following notation is used in the figures:

1 - the first border of the cursor (position of the desired location) of the cursor;

2 - the second border of the cursor;

3 - edit field;

4 - cursor (cursor area).

In order to simplify the description of the claimed invention and for definiteness, we assume that the user works with only one line. That is, on the display screen of the user's computer, one editing field 3 is horizontally located. In edit field 3, black characters are displayed on a white background. In practice, a user can work with a string to enter a search query in one of the information retrieval systems.

Let us consider a computer-implemented method for generating a text cursor 4 in an editing field 3 in the user interface, in which a cursor 4 is formed in the form of an area with a background whose color is different from the original background color of the editing field 3 and is contrasting with the font color of the displayed text ( see paragraph No. 1 of the claims).

Let the user interface designer decide that in its interface the length of cursor 4 should be equal to three familiarities, that is, the sum of the three characters included in it, taking into account the pixel characters separating the data, the original font color of the displayed text should be black, the original background color of the edit field 3 is white, and the cursor color 4 is gray.

Let also in the initial state in the edit field 3 a word is displayed having the following form “12345” (see Fig. 1). That is, this word consists of an increasing sequence of five digits, starting with the number “1” and ending with the number “5”, with the first character of this word in position No. 1, and the last in position No. 5.

Let the user decide to place cursor 4 between the numbers “4” and “5”, and until that moment cursor 4 was not in edit field 3.

With the known method of forming the cursor in the form of a vertical bar in the initial position, the cursor would be between the number "1" and the beginning of the line. When forming cursor 4 by the claimed method, the cursor 4 will not be visible in the initial position, that is, in the initial position, only the word with the following form “12345” is displayed in the edit field 3.

The user can realize his intention to set the cursor between the numbers “4” and “5” by positioning the mouse pointer between these numbers and left-clicking.

Then, after a user clicks with the left mouse button, cursor 4 is formed in the form shown in FIG. 1 in the following manner.

Below in the description of the invention in italics a text is taken, taken from the claims and which requires explanation.

In the field 3 for editing the user interface, the position of the desired cursor location 4 is determined.

From the point of view of the computing system, setting the mouse pointer between these numbers and clicking the left mouse button with the user may mean receiving through the user interface information about the location of the mouse pointer in the edit field 3, expressed in pixels.

Summing the widths of the characters, expressed in pixels, and pixels separating the characters, starting from the beginning of the edit field 3, determine the moment when the received amount exceeds the value of the location of the mouse pointer in the edit field 3.

Summing the widths of the characters, they simultaneously store (in the computer's memory) in the array the positions of the characters occupied by them in the edit field 3.

When the received sum is exceeded, the value of the location of the mouse pointer in the edit field 3 remembers the position number of the symbol, the addition of which resulted in the excess.

The unit is subtracted from the stored position number and the position number of the desired cursor location 4 is obtained.

Considering the determination of the position number of the desired location of the cursor 4 using the mouse pointer, it can be said that the position number of the desired location of the cursor 4 is the position number of a nearby character in the opposite direction to the character input direction, regardless of the location of the mouse pointer in the edit field 3. Looking ahead, it should be noted that in the method according to paragraph 6 of the claims, under certain conditions, determining the position number of the desired location of the cursor 4 using the mouse pointer may depend on the location of the mouse pointer in the edit field 3 (discussed in more detail below when describing paragraph 6 of the formula inventions).

From the FIG. 1 of the example shows that at the time of adding the width of the character "5" the resulting amount will exceed the value of the location of the mouse pointer and, therefore, at the position of the desired cursor location 4 is the number "4".

Determining the position of the desired location of the cursor 4 by using the keyboard is different. Knowing the current position of cursor 4, the following can be determined. By pressing the right arrow key, the cursor 4 position number increases by one if the current cursor 4 position is less than the maximum possible position in edit field 3.

Pressing the “left arrow” key decreases the position number of cursor 4 by one, if the current position of cursor 4 is not at the beginning of edit field 3.

Next, check the following condition:

“If the position number of the desired cursor location 4 is not less than the position number of the start of edit field 3”.

In this example, the position number of the desired location of cursor 4 is four and this number is greater than one (in this example, the position of the start of edit field 4 is one), therefore, this condition is fulfilled and proceed to the next operation of the claimed method.

The first border 1 of the cursor 4 is set to the position of the desired location of the cursor 4, and the second border 2 of the cursor 4 is set in the interval starting with the position of the beginning of the edit field 3 and ending with the position of the first border 1 of the cursor 4.

The first border 1 of cursor 4 is set to the position of the desired location of cursor 4.

After you have determined the position of the desired location of the cursor 4, which in the considered example is four and contains the number “4”, the first border 1 of the cursor 4 is set to the position of the desired location of the cursor 4.

The cursor position 4 is the area occupied by the symbol (familiarity) in this position. The right border of this symbol (its extreme pixel on the right) is the right border of the cursor 4, formed by the claimed method. The right border of this symbol can be attributed to a pixel separating adjacent characters, if any (if it is not the last in the line).

In the example of FIG. 1, the first boundary 1 is set at position four. As will be seen below, this border (familiarity) will have a certain background color (familiarity background).

The second border 2 of the cursor 4 is set in the interval starting with the position of the beginning of the edit field 3 and ending with the position of the first border 1 of the cursor 4.

Since, as noted above, the length of cursor 4 is set by the developer to three familiarities, that is, the sum of the three characters included in it, taking into account the pixels separating the data, the ability to set the second border 2 in the edit field 3 is determined (is there room for its installation) . The cursor 4 cannot go beyond the start of the edit field 3, that is, its second border 2 cannot be located less than the position number of the start of the edit field 3.

The position of the beginning of the edit field 3 can be denoted by zero, one or any digit, therefore, in the claims there is no specific reference to a specific position number of the start of the edit field 3. In this description, for definiteness, the position of the start of the edit field 3 is one.

In the example of FIG. 1, the first boundary 1 is set at position four. The location of the second border 2 is determined by subtracting from the position number 1 the desired location of the cursor 4, which in this example is four, the length of the cursor 4, which in this example is three, and adding one to the resulting difference. Subtract three from four and add one, we get two. Thus, the second border 2 should be set to position two, which lies in the interval starting with the start position of the edit field 3 (the number of this position is one) and ending with the first border 1 of cursor 4 (the position number is four).

If the length of cursor 4 was set by the user interface designer to five and the position of the desired location of cursor 4 is four, as shown in FIG. 1, from the calculation of four minus five plus one, it would turn out that the second border 2 of cursor 4 should be set to position zero, which is not in edit field 3 (positions in it start from one). In this case, the second border 2 of the cursor 4 would be set to the beginning of the edit field 3. Moreover, the length of cursor 4 would be reduced to four characters (familiarity). If you further press the left arrow, then with each press of it, the length of cursor 4 would decrease by one until it would become equal to zero.

Since the length of the cursor 4 can be selected by the user interface designer, the second border 2 of the cursor 4 relative to the first border 1 of the cursor 4 can be in any position of the edit field 3, but only within the above-mentioned interval.

The cursor 4 is displayed with a background whose color is different from the original background color of the edit field 3 and is contrasted with the font color of the displayed text.

In FIG. 1 shows a gray cursor 4, which is different from the original white background color of the edit field 3 and is contrasting with the black color of the font of the displayed text. In FIG. 1 cursor 4 has a length of three familiarity, namely it occupies the familiarity of the numbers "2", "3" and "4". The familiarity occupied by the number "4" is the first border 1 (position of the desired location) of the cursor 4, and the familiarity occupied by the number "2" is its second boundary 2.

If in this case you press the “Delete” key, then the number “5” will be deleted, if you press the “BackSpace” key, then the number “4” will be deleted, that is, the first border 1 (cursor 4) also functions as a cursor pointer , as well as the well-known cursor, formed in the form of a vertical bar, if it was between the numbers "4" and "5".

In the edit field 3, outside the cursor 4, positions are determined in which the background color is different from the original one, and if there are any, then in these positions the background color is replaced with the original one.

Since in this example (Fig. 1) initially the cursor 4 was not in the edit field 3, then outside the cursor 4 (Fig. 1) in all positions of the edit field 3 the background color coincides with the original white color. Therefore, in this case, nothing needs to be changed in the edit field 3 outside of cursor 4.

If cursor 4 were earlier to the right one position compared with cursor 4 shown in FIG. 1, that is, the position from the third to the fifth inclusive would be gray, then when you press the left arrow key, cursor 4 would move left one position and be where it is shown in FIG. 1. In this case, in the position with the number “5”, the background of the edit field 3 would remain gray from the previous cursor position 4. To avoid this, it is necessary in this position with the number “5” to replace the background color gray with the original white background color. That is, this operation of the claimed method is necessary to remove the "trace" left by the cursor 4 when moving it.

If the position number of the desired location of the cursor 4 is less than the position number of the beginning of the edit field 3, then the cursor 4 in the edit field 3 is not displayed.

Let the cursor 4 be in the position with the number four (see Fig. 1) and the user two times in succession press the left arrow key. As a result of this, cursor 4 moved to two positions and the first border 1 of cursor 4 is set to position two, and the second border 2 of cursor 4 to position one. Cursor 4 length decreased from three familiarity to two familiarity. The next time the user presses the left arrow, the position numbers of the first border 1 of cursor 4 and the second border 2 of cursor 4 will coincide and will be equal to one.

The next time the user presses the left arrow key, the position value of the first border 1 of cursor 4 should decrease by one and be zero, that is, less than one (in this example, the position of the start of edit field 3 is one). In this case, cursor 4 in edit field 3 is not displayed.

That is, if cursor 4 is not in the edit field 3, then it is considered that cursor 4 is in front of position No. 1. So in this case, when the “Delete” key is pressed in the example shown in FIG. 1, the number “1” displayed in the first position of the edit field 3 will be deleted, and when entering the number “6” it will replace the number “1” if the “Insert” character insertion mode is not activated.

When a user works with only one line, for example, when entering search query words in the search engine interface, then no problem arises, since if cursor 4 is absent, it is logical to assume that the first character will be entered from the first position of edit field 3.

However, in a multi-page document with many such blank lines, the problem of determining the location of cursor 4 in one of these lines may arise.

To solve this problem, the applicant proposes the following.

If this field 3 is not empty, then the first border 1 of cursor 4 is placed at the beginning of the edit field 3, its second border 2 is placed at the end of the edit field 3, this field 3 is displayed with a background whose color is different from its original color and is contrasting with to the font color of the displayed text.

That is, the applicant proposes to display the entire edit field 3 with a background whose color is different from its original color and is in contrast to the font color of the displayed text. In other words, set the length of cursor 4 equal to the length of the entire line (edit field 3). In this case, the cursor 4 has the maximum possible length and, therefore, makes it as noticeable as possible.

If the entire edit field 3 is filled with a color different from the original color, then this means that there are no characters in the edit field 3 (edit field 3 is empty) and cursor 4 is at its beginning. If a well-known cursor formed in the form of a vertical line in black were used in the edit field 3, then it would be in front of the number “1” in the considered example (see Fig. 1).

If this field 3 is empty, then the first border 1 of cursor 4 is placed at the beginning of the edit field 3, its second border 2 is placed at the end of the edit field 3, this field 3 is displayed with a background whose color is different from its original color and is contrasted with the font color of the displayed text, and / or one or more predetermined characters are displayed in this field 3, informing the user about the cursor 4 in this empty field 3, which (e) is deleted when the first character is entered in the editing field 3.

If the edit field 3 is empty, then it is possible to output predetermined characters informing the user about the cursor 4 in this empty edit field 3. For example, you can display the text “This field is empty”, “The string is empty” in the middle of it, or at the beginning of it print several characters “<” (the character “less”), for example, “<<<<<<<<”, indicating that so that cursor 4 is at the beginning of edit field 3. When you enter the first character in edit field 3, which will be displayed in position number one, all explanatory characters previously displayed in this edit field 3 are deleted, freeing up space for user-entered characters.

An example was considered above, in which it was assumed that the user interface designer set the cursor length 4 of a certain length to three. The length of cursor 4 changed, in this case it decreased, when moving the first border 1 of cursor 4 from position three to position two, and if the position number of cursor 4 was greater than or equal to three, then its length remained constant.

Other dependences of the length of the cursor 4 on the position of the cursor 4 in the edit field 3 are possible.

The length of cursor 4 may depend on the length of the word on which the first border 1 of cursor 4 is located, and simultaneously on the position number of the first border 1 of cursor 4 in a given word. The method of forming the cursor 4, in which the length of the cursor 4 is so dependent on the location of the first border 1 of the cursor 4, is described in paragraph 4 of the claims, which has the following form:

"The method according to paragraph 1 or 2, in which the second border 2 of cursor 4 is positioned at the beginning of the current word."

This is especially convenient for the user when entering text in the edit field 3, since in this case the input word is highlighted in the text with its background color different from the original background color of the edit field 3. In this case, there is no uncertainty as to which of the borders of cursor 4 is the cursor cursor 4. In addition, highlighting the current word with the background color allows the user to focus on it.

The beginning of the current word can be determined as follows.

The horizontal coordinate of the mouse pointer is determined, the widths of the characters in pixels (and the pixels separating these characters) are summed, starting from the beginning of the line, until their sum exceeds the previously determined horizontal coordinate of the mouse pointer. The moment when the received sum exceeds the previously determined horizontal coordinate of the mouse cursor means that the current character belongs to the current word. Further, continuing the sequential reading of the characters of the current word from right to left, determine the first character of the current word, which is different from the space or is the first character of the line (if the word is at the beginning of the line), and also determine the number of its position in the line (in edit field 3).

If the user used the computer keyboard to move the cursor 4, then the beginning of the current word is determined differently.

In FIG. 2 depicts two words: “123” and “5678”. In this example, the numbers that form these words simultaneously indicate the position in which they are located. For example, the number “5”, which is the first digit of the second word, is in the fifth position of edit field 3.

If the user sets the mouse pointer between the numbers “6” and “7” of the second word and clicks the left mouse button, control will be transferred to the program handler, which according to the appropriate algorithm will determine the first character of the current word, determine the position of the first border 1 of cursor 4, which will be equal to six, set the second border 2 of cursor 4 to the beginning of the current word, that is, to position number five and displays the numbers “5” and “6” with a gray background. As a result of this, the cursor 4 will be formed as shown in FIG. 2.

There is another way of forming the cursor 4 (see paragraph 5 of the claims) according to which the second border 2 of the cursor 4 is located at the beginning of the edit field 3 (see Fig. 3). According to the applicant, this method of forming cursor 4 is the best.

If the user sets the mouse pointer between the numbers “6” and “7” of the second word (see Fig. 3) and left-clicks, control will be transferred to the program handler, which will determine the position of the first border 1 of cursor 4, which will be equals six, sets the second border 2 of cursor 4 to the beginning of the current edit field 3, that is, to position one, and edit field 3 from the first position to the sixth position inclusively will be displayed with a gray background (grayed out). The cursor 4 in this case will have the form according to FIG. 3.

In this case, any uncertainty is excluded as to which of the borders of cursor 4 is the pointer 1 of cursor 4, and also as the text is entered, the length of cursor 4 increases and can reach its maximum — the length of the entire edit field 3, that is, the maximum visibility.

Above, we examined the method of forming cursor 4, in which the area of cursor 4 (the “body” of cursor 4) is indicated by the background color different from the original background color of the edit field 3. However, another way of forming cursor 4 is also possible (see point 2), in which cursor 4 itself is formed by the characters themselves, but with different font characteristics with respect to characters that are outside of cursor 4.

For definiteness, we assume that cursor 4 will be formed by characters displayed in bold, and the original font will be normal.

The description of this method is similar to the previously given description of the method of forming the cursor 4 in paragraphs No. 1, No. 4 and No. 5. The only difference is that the characters forming cursor 4 will be displayed in bold without changing the background color. So, depicted in FIG. 1 the digits “2”, “3”, “4” will not be displayed in regular font, but in bold and they will be displayed on a white background, in FIG. 2. the numbers "5" and "6" will not be displayed in regular type, but in bold and they will be displayed on a white background, in FIG. 3. the numbers "1", "2", "3", "5" and "6" will not be displayed in regular font, but in bold and they will be displayed on a white background (symbol output in bold is not shown in the figures). That is, if in FIG. 1, FIG. 2 and FIG. 3 mentally replace the characters forming cursor 4, displayed in regular font with characters in bold, then these figures can be used to illustrate the claimed method according to paragraphs 2, 4 and 5.

The edit field 3 is displayed with a background whose color is different from its original color and is contrasted with the font color of the displayed text, only if this edit field 3 is empty.

In this case, the first border 1 of cursor 4 is placed at the beginning of the edit field 3, its second border 2 is placed at the end of the edit field 3, this edit field 3 is displayed with a background whose color is different from its original color and is contrasted with respect to the font color of the output text.

The method according to paragraph 2 of the claims only works if a monospace font is used in the user interface, that is, it is a font in which all the characters (more precisely, the pins of the characters) have the same width. If proportional font characters are entered in the edit field 3, in which the characters differ in width from each other, then it is necessary to introduce an additional operation according to paragraph 3 of the claims.

This is due to the fact that the widths of the characters that make up cursor 4 will differ from the width of the same characters, but until cursor 4 is formed, as a result of which the sum of these character widths will be a variable. In order to take into account this change, the text is re-displayed in the edit field 3, starting with the first character of the cursor 4 area.

In other words, so that the characters of cursor 4 do not go over the characters following it (the sum of the characters of cursor 4 is greater than the sum of these characters before falling into the area of cursor 4) or so that there is no gap between the first border 1 of cursor 4 and the characters following it (the sum characters of cursor 4 are less than the sum of these characters before falling into the cursor area 4) it is necessary to re-display the text in field 3 of editing, starting with the first character of cursor area 4.

If we set the task to form cursor 4 so that at any location of its first border 1 (cursor 1 pointer 4) in the edit field 3, the length of cursor 4 would be at least half the length of the edit field 3, then the solution to this optimization problem will be as in paragraph 6 of the claims.

First determine the position of the desired location of the cursor 4, as well as expressed in pixels, the location of its location. How exactly this happens was partially described above when describing the example illustrated in FIG. 1.

If the value expressed in pixels for the location of the desired location of cursor 4 is greater than or equal to the value expressed in pixels for the middle of the edit field 3, then the first border 1 of cursor 4 is set to the position of a nearby character in the direction opposite to the direction of inputting characters, and the second border 2 of cursor 4 is set to beginning of edit field 3, otherwise the first border 1 of cursor 4 is set to the position of a nearby character in the direction of inputting characters, and the second border 2 of cursor 4 is set to the end Olya 3 editing.

Consider the example of FIG. 4, which shows an editing field 3 of eight characters in length, completely filled with one word “12345678”, consisting of a sequence of numbers. This example is designed so that it is easy to determine the middle of the editing area 3. The middle of editing area 3 is between position No. 4 and position No. 5, which corresponds to its location between the numbers “4” and “5”.

Let the user decide that the position of the desired location of the cursor 4 should be between the second and third position, if the cursor 4 would be formed in a known manner in the form of a vertical bar.

In this case, the value expressed in pixels for the location of the desired cursor location does not satisfy the condition “greater than or greater than and equal to” expressed in pixels as the middle of the edit field 3 (this can be seen from Fig. 4, in which the third position is less than the fourth position), and therefore the position of the desired location of cursor 4 will be equal to the position of a nearby character in the direction of inputting characters, namely, position No. 3, in which the character "3" is located.

Then, the first border 1 of cursor 4 is set to the position of the desired location of cursor 4.

The first border 1 of cursor 4 is set to position No. 3, that is, to the position where the number "3" is located (see Fig. 4).

The second border 2 of the cursor 4 is set at the end of the edit field 3 (see Fig. 4). In this case, cursor 4 occupies positions three through eight, inclusive, and its length is six characters of characters, which is more than half the length of edit field 3.

Let the user now decide that the position of the desired location of the cursor 4 should be between the sixth and seventh position, if the cursor 4 would be formed in a known manner in the form of a vertical bar.

In this case, the value expressed in pixels of the location of the desired cursor location satisfies the condition “greater than or greater than and equal to” the expressed in pixels value of the middle of the edit field 3 (this can be seen from Fig. 5, in which the sixth position is greater than the fourth position), and therefore, the position the required cursor location 4 will be equal to the position of the neighboring character in the opposite direction to the character input direction, namely, position No. 6, in which the symbol "6" is located.

Then, the first border 1 of cursor 4 is set to the position of the desired location of cursor 4.

The first border 1 of cursor 4 is set to position No. 6, that is, to that position where the number "6" is located (see Fig. 5).

The second border 2 of the cursor 4 is set at the beginning of the edit field 3 (see Fig. 5). The cursor 4 in this case occupies the positions from the first to the sixth, inclusive, and its length is equal to six familiar characters, which is more than half the length of the edit field 3.

Next, the area of the cursor 4 is displayed with a background whose color is different from the original background color of the edit field 3 and is contrasted with the font color of the displayed text. In the edit field 3, outside the area of the cursor 4, in which the background color is different from the original, the background color is replaced with the color of the original background of the edit field 3.

In FIG. 4 and 5, the background color of edit field 3 is white, and cursor 4 is gray.

In the example of FIG. 4 and in the example of FIG. 5, cursor 4 is formed with a length of at least half the length of the edit field 3.
