Embodiment
In order to improve the accuracy and efficiency of cursor movement, the embodiment of the invention provides a kind of cursor movement prompting method, in this method, when cursor is positioned at a certain position of editing area, to show to carrying out the target position information that cursor arrives behind the cursor movement according to one party, so that the user can predict next step in the one party position of cursor movement that makes progress, and then carry out correct cursor movement.
Referring to Fig. 1, the cursor movement prompting method that the embodiment of the invention provides specifically may further comprise the steps:
Step 10: determine the current location of cursor in editing area;
Step 11: determine with cursor from the current location in editing area according to setting walk direction walk after the position that arrives of this cursor, with this position as the cursor destination locations;
Step 12: setting walked direction and the information of the cursor destination locations determined is carried out output display as the information that walks.
In the step 11, determine with cursor from the current location in editing area according to setting walk direction walk after the position that arrives of this cursor, its concrete methods of realizing can be as follows:
According to the first corresponding relation of predefined cursor current location, the direction that walks and cursor destination locations, determine the current location of cursor in editing area, set the corresponding cursor destination locations of direction that walks.First corresponding relation here is equivalent to the predefined rule that walks, this has walked rule predetermining cursor when being positioned at each position of editing area, with cursor according to one or more directions that walk destination locations that rear cursor arrives that walks.For example, for formula as shown in Figure 1, the rule that walks can be stipulated: in the formula molecule during left side of " b ", be the left side of " 2a " in the denominator with cursor according to direction corresponding to the lower directionkeys destination locations that rear cursor arrives that walks in the current location of cursor; In denominator during the left side of " 2a ", be " b in the radical sign in the molecule with cursor according to walk destination locations that rear cursor arrives of direction corresponding to upper directionkeys in the current location of cursor
2" the left side.
In the step 12, setting walked direction and the information of the cursor destination locations determined shows, concrete, can be at cursor destination locations place display setting identifier corresponding to direction that walk.This identifier comprises arrow, character, numeral etc.For example, setting walk direction be on during direction corresponding to directionkeys, show upward arrow at the cursor destination locations; Walk direction when being direction corresponding to lower directionkeys in setting, arrow under the cursor destination locations shows.
Better, can utilize the setting of determining in the step 11 cursor destination locations corresponding to direction that walk to carry out actual cursor movement, specific implementation can adopt following dual mode:
The first after the position that this cursor arrives after the direction of determining cursor walked according to setting from current location walks, can be preserved walk the second corresponding relation of direction and cursor destination locations information of this setting; And after the cursor movement request that receives direction that this setting walked, determine this setting cursor destination locations information corresponding to direction that walks according to the second corresponding relation of preserving, and with cursor movement this cursor destination locations place in the editing area.For example, determine cursor is walked according to the direction that walks corresponding to upper directionkeys from position A after the position that arrives of this cursor be the B position, then preserve the corresponding relation of upper directionkeys and position B, and after the cursor movement request that directionkeys is corresponding on receiving namely goes up directionkeys and is pressed, determine that according to the corresponding relation of preserving upper cursor destination locations corresponding to directionkeys is B, and then with the position B place of cursor movement in the editing area.
The second, after current location, the setting of definite cursor in editing area walks the corresponding cursor destination locations of direction, the position coordinates of the subregion number, this current location of preserving the current location place of cursor in described subregion, set the 3rd corresponding relation of walk direction and the cursor destination locations information of determining, described subregion belongs to the subregion that described editing area namely is described editing area; And after the cursor movement request that receives direction that this setting walked, determine subregion number and the position coordinates of this current location in this subregion at the current location place of cursor, determine this subregion number, this position coordinates, this setting cursor destination locations information corresponding to direction that walks according to the 3rd corresponding relation of preserving, and with cursor movement this cursor destination locations place in the editing area.Here, subregion number can be preserved in as shown in Figure 4 the node object pointer, the current location of cursor can be kept in as shown in Figure 4 the cursor data, cursor destination locations information can be preserved in as shown in Figure 4 the displaing coordinate, sets the direction that walks and can be kept in as shown in Figure 4 the directional information.
For example, determine cursor is walked according to the direction that walks corresponding to upper directionkeys from position A after the position that arrives of this cursor be the B position, the subregion at A place, position number is 1, then preserves the corresponding relation of the coordinate of subregion number 1, the coordinate of position A, upper directionkeys and position B; After the cursor movement request that directionkeys is corresponding on receiving is namely gone up directionkeys and is pressed, determine that according to the corresponding relation of preserving subregion number 1, position A, the cursor destination locations that upper directionkeys is corresponding are B, and then with the position B place of cursor movement in the editing area.
Better, when the information of setting is walked direction and cursor destination locations shows, can also further show structural information and/or above-mentioned the first corresponding relation (rule namely walks) for the treatment of content of edit in the editing area, the structural information for the treatment of content of edit has the structural information of formula, chemical formula etc. in the editing area.
Among the present invention, editing area can include but not limited to: formula region, or chemical structural formula region, or the chemical equation region etc.
Among the present invention, the direction that walks of cursor can include but not limited to: one or the corresponding direction of directionkeys of combination in any in the input keyboard in upper directionkeys, lower directionkeys, LeftArrow, right key, the compound keys.
As shown in Figure 2, be the flow process that the formula cursor movement prompting method is realized.At first, according to information such as the position of current cursor and levels, then go iteration to want walk position and the key mapping of pointing out.Position by current coordinate begins, and calculates successively by current cursor and presses each information such as the resulting node pointer of key that walk, until all may all traveling through of will walking are finished.Then the information that obtains is carried out the management of an overall situation.
Then the information that obtains is passed to display module.Display module reads coordinate figure and directional information wherein, according to these information the prompting of each position is shown.That direction is left such as the information of reading, coordinate x1, y1.So just at coordinate x1, draw an arrow left on the position of y1 and represent to go to here by the enough cursors of LeftArrow.
Concrete:
Steps A: according to the predefined rule that walks determine with cursor from current location according to a certain setting walk direction walk after the position that arrives of this cursor, with this position as the cursor destination locations;
Step B: judge whether the location positioning flow process finishes, namely judge whether to determine the cursor destination locations of each direction that walks, if not, then arrive step C; If, to step D;
Step C: deposit fixed cursor destination locations in the destination locations information list, and return steps A;
Step D: the cursor destination locations of the fixed direction that walks is carried out output display, carry out cursor movement for the user according to the information that shows.
As shown in Figure 3, be the data organizational structure that the formula cursor movement prompting method is realized.This structure is the data that the overall situation is unique, because the cursor of formula can only have one, and these data are conversion along with the conversion of individual cursor.If cursor is not moving in same position, this value just can not upgraded so, in order to reduce operand.
Structure as shown in Figure 3 shows that to prompting the data of two keys that work are: directional information and coordinate data.As long as there are these two information just can provide complete prompting.And other information also is indispensable.It is the effect of playing a buffer memory, because the position that just will move it before mobile cursor is just good to calculating, does not just need again to have done the calculating of a cursor movement so when real mobile cursor again.The node object data and the cursor data that directly read on the respective direction just can navigate to corresponding position to cursor.Improved like this efficient.
