Example two
Fig. 2 is a flowchart of a text rendering and layout method according to a second embodiment of the present invention, where in this embodiment, "determining a target text and an area to be operated" is performed on the basis of the second embodiment, where the target text and the area to be operated are optimized according to the operation type, an editing object corresponding to the editing operation, and a text associated with the editing object. Referring to fig. 2, the method may specifically include the following steps:
s210, obtaining an operation type of the editing operation received by the text box, wherein the operation type comprises at least one of the following: input operation, paste operation, delete operation, and modify attribute operation.
And S220, if the operation type is an input operation or a paste operation, determining a first editing object corresponding to the input operation or the paste operation.
Specifically, when the operation type of the editing operation is an input operation or a paste operation, a first editing object corresponding to the input operation or the paste operation is determined. In a specific example, fig. 1b shows a schematic diagram of a transformation of an input operation or a paste operation, and referring to the text box shown in fig. 1b, the layout form of the original text in the text box is: the first line 12324214, the second line 21421442, and the third line 214, the detected input operation is to input character 5 (or to paste copied character 5), and then character 5 is the first editing object. The operation type of the first editing object may be an input operation, that is, a user inputs through a keyboard, or may be a paste operation, in which the user copies from another location of the document or another document and pastes the document into the text box.
And S230, determining the relative target position of the first editing object in the text box.
Optionally, the relative target position of the first editing object in the text box is determined by the document management component, in a specific example, referring to fig. 1b, the target relative position of the character 5 in the text box refers to a distance from the character 5 to the first character (character 1 in the first line) of the paragraph, and illustratively, the distance may be represented by a number of characters, that is, the relative target position of the first editing object character 5 in the text box is 19 characters away from the first character 1 in the first line of the paragraph.
And S240, determining a target text according to the relative target position.
Specifically, the relative target positions are classified according to their difference in the text box, for example, the relative target positions may be the number of characters spaced from the first character of a certain paragraph of text, or the number of characters spaced from the character having some specific mark in a certain paragraph, where the character having a specific mark may be an artistic word, a bold font, or an underlined font, etc. For example, the target text is determined to be different if the relative target position is different, for example, the target text may be text input to the text box by an input operation, or may be text pasted by a paste operation and associated text after the pasted text.
S250, determining an actual target position according to the relative target position, and determining the region to be operated according to the actual target position, wherein the actual target position comprises an actual position of the first editing object in the text box.
Specifically, the actual target position is determined according to the relative target position, where the actual target position includes an actual target position of the first editing object in the text box, and for example, the actual target position refers to coordinates of the corresponding character in the display screen. For example, the actual target position may be determined in such a manner that each character in the paragraph corresponds to an actual target position, and the actual target position is determined by a relationship between the relative target position and the actual target position, for example, if the actual target position of the first character in the paragraph is a, and the relative target position is 19 characters away from the first character in the first line in the paragraph, the actual target position B may be determined, and the region to be operated is determined according to the actual target position B. In a specific example, the region to be operated is a region in a text box corresponding to the actual target position B.
And S260, rendering the target text, and displaying the target text in a layout mode in the area to be operated.
Optionally, determining the target text according to the relative target position includes: and if the relative target position is a segment tail, determining that the first editing object is a target text. And determining whether the relative target position is a paragraph tail, namely, determining that no other text follows the first editing object in the paragraph through the document management component, wherein the first editing object is the target text. Referring to fig. 1b, a character 5 is entered or pasted at the end of the paragraph, followed by no other characters, and in this particular example, the first editing object character 5 is the target text.
On the basis of the above technical solution, a specific example is used to describe a case where the editing object is at the end of a segment. Firstly, when character input is detected, the document management component can search paragraphs to which the characters needing to be input belong, and determine whether the relative target position is at the end of the paragraph. Secondly, the rendering component is started to render the character 5, the position (to-be-operated area) of the character 5 needing to be laid out is determined through the layout component, the character 5 is laid out, and other characters are not moved.
Optionally, determining the target text according to the relative target position includes: and if the relative target position is in a section, determining the first editing object and the associated text of the first editing object as target texts, wherein the associated text of the first editing object comprises the text behind the relative target position.
Wherein, fig. 1c shows a schematic diagram of a transformation of an input operation or a paste operation, referring to the text box shown in fig. 1c, the layout form of the original text in the text box is: the first line 123242142, the second line 142144221, and the third line 4, the detected input operation is to input a character 5 (which may also be to paste the character 5) after the second line 4 th character 1, and the character 5 is the first editing object. Thus, determining that the relative target position is in the segment, the first edited object 5 and the associated text of the first edited object 5 may be determined by the document management component as the target text, optionally, the associated text of the first edited object 5 includes the text after the relative target position, and in fig. 1c, the associated text of the first edited object 5 includes 442214. The determined target text does not include text prior to the relative target position, providing conditions for not repeating the rendering and/or layout.
On the basis of the above technical solution, a specific example is used to describe a case where the editing object is in a segment. Firstly, when character input is detected, the document management component can search the paragraph to which the character to be input belongs, and determine whether the relative target position is in the paragraph. Secondly, a character rendering component is started to render the character 5, a region to be operated is determined through a layout component, and the character 5 and characters behind the character 5 are laid out in the region to be operated. Illustratively, it is also possible to calculate whether there is an augmentation of the number of lines after the input character 5, and if so, to shift the subsequent paragraph as a whole without changing the shift of the individual characters.
In the embodiment of the invention, if the operation type is an input operation or a paste operation, a first editing object corresponding to the input operation or the paste operation is determined; determining a relative target position of the first editing object in the text box; determining a target text according to the relative target position; and determining an actual target position according to the relative target position, and determining the region to be operated according to the actual target position, wherein the actual target position comprises the actual position of the first editing object in the text box. Aiming at the input operation and the pasting operation, the target text needing to be rendered and/or laid out and the area to be operated to which the target text needs to be laid out are determined, so that repeated rendering and/or laying out of other irrelevant texts are avoided, and the response speed to the editing operation is improved.

In general, the width-fixed state is a common use state, the width-fixed state is a state in which automatic line feed can be realized, and the width-adaptive text box means that the input text always remains as one line for input and automatic line feed cannot be realized. In the above embodiments, the text boxes are all text boxes with fixed widths, and for the case of adaptive width, the width of the text box may be automatically expanded, if line feed is not performed manually, the segment has only one line, and when inputting or deleting, the processing situation is similar to the case of fixed-width input, which is not described herein again.
On the basis of the technical scheme, the input operation and the pasting operation also comprise an operation of selecting and replacing the specified text, and the method can be specifically realized by preferentially comparing whether the lengths of the text in the selected area and the replacement text are consistent (whether the attributes are consistent or not does not need to be considered), if the lengths are consistent, only rendering the replacement text and laying out the replacement text, and otherwise, not changing the replacement text; if the lengths are not consistent, characters other than the replacement text need to be rearranged in addition to rendering the replacement text.
