It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention.
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the invention and, together with the description, serve to explain the principles of the invention.
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise represented. The implementations set forth in the following description of exemplary embodiments do not represent all implementations consistent with the invention. Instead, they are merely examples of devices and methods consistent with some aspects related to the invention as recited in the appended claims.
As shown in
In some embodiments, when the first touch operation is conducted in the input box of the touch screen, a sensor on the touch screen senses the first touch operation and sends a signal to a processor and forwards sensed information to the processor. The processor determines positions of an operation starting point and an operation ending point of the first touch operation according to the received information, and obtains the first operating distance of the first touch operation according to the determined positions.
The target content can be determined according to the position of the operation starting point or the position of the operation ending point of the first touch operation. The target content can be content in a line associated with the operation starting point or the operation ending point, or content in a range from the nth line above to the nth line below the line containing the operation starting point or the operation ending point, where n is a preset positive integer. In some embodiments, the target content can be determined according to the positions of the operation starting point and the operation ending point of the first touch operation. For instance, the target content may be the content between the operation starting point and the operation ending point of the first touch operation.
At S102, the target content is moved by a distance corresponding to the first operating distance along the first operating direction to form a blank space between a side of the input box and a side edge of the target content. An edge of the target content in the input box refers to a boundary of a region within which the target content is located, for example, a boundary of a region displayed when a selection operation is performed on the target content in the input box.
In some embodiments, when the first operating distance is less than a preset distance, the target content is moved by the first operating distance along the first operating direction. On the other hand, when the first operating distance is not less than the preset distance, the target content is moved by the preset distance along the first operating direction. In some embodiments, the preset distance equals a product of a width of the input box in the first operating direction and a preset percentage.
For example, the first touch operation is a swiping from left to right, the first operating direction is from left to right, the first operating distance is S1, the width of the input box in the left-right direction is W, and the preset percentage is 20%. When S1<W×20%, the target content is moved by S1 along the direction from left to right. When S1≧W×20%, the target content is moved by W×20% along the direction from left to right. As a result, a blank space is formed between a left side of the input box and a left edge of the target content.
As another example, the first touch operation is a swiping from right to left, the first operating direction is from right to left, the first operating distance is S1, the width of the input box in the left-right direction is W, and the preset percentage is 20%. When S1<W×20%, the target content is moved by S1 along the direction from right to left. When S1≧W×20%, the target content is moved by W×20% along the direction from right to left. As a result, a blank space is formed between a right side of the input box and a right edge of the target content.
For example, the first touch operation is a swiping from up to down, the first operating direction is from up to down, the first operating distance is S1, the width of the input box in the up-down direction is H, and the preset percentage is 20%. When S1<H×20%, the target content is moved by S1 along the direction from up to down. When S1≧H×20%, the target content is moved by H×20% along the direction from up to down. As a result, a blank space is formed between an upper side of the input box and an upper edge of the target content.
As another example, the first touch operation is a swiping from down to up, the first operating direction is from down to up, the first operating distance is S1, the width of the input box in the up-down direction is H, and the preset percentage is 20%. When S1<H×20%, the target content is moved by S1 along the direction from down to up. When S1≧H×20%, the target content is moved by H×20% along the direction from down to up. As a result, a blank space is formed between a lower side of the input box and a lower edge of the target content.
In some embodiments, the target content is determined to be content in the line containing the operation starting point of the first touch operation. In this scenario, S102 includes moving the content in the line containing the operation starting point of the first touch operation by a distance corresponding to the first operating distance along the first operating direction to form the blank space between the side of the input box and the side edge of the content in the line containing the operation starting point.
For example, the first touch operation is a swiping from left to right, the first operating direction is from left to right, the first operating distance is S1, the width of the input box in the left-right direction is W, the preset percentage is 20%, and the line containing the operation starting point of the first touch operation is the ith row. When S1<W×20%, the content of the ith row are moved by S1 along the direction from left to right. When S1≧W×20%, the content of the ith line are moved by W×20% along the direction from left to right. As a result, a blank space is formed between a left side of the input box and a left edge of the content of the ith TOW.
As another example, the first touch operation is a swiping from right to left, the first operating direction is from right to left, the first operating distance is S1, the width of the input box in the left-right direction is W, the preset percentage is 20%, and the line containing the operation starting point of the first touch operation is the ith row. When S1<W×20%, the content of the ith row are moved by S1 along the direction from right to left. When S1≧W×20%, the content of the ith row are moved by W×20% along the direction from right to left. As a result, a blank space is formed between a right side of the input box and a right edge of the content of the ith row.
For example, the first touch operation is a swiping from up to down, the first operating direction is from up to down, the first operating distance is S1, the width of the input box in the up-down direction is H, the preset percentage is 20%, and the line containing the operation starting point of the first touch operation is the jth column. When S1<H×20%, the content in the jth column are moved by S1 along the direction from up to down. When S1≧H×20%, the content in the jth column are moved by H×20% along the direction from up to down. As a result, a blank space is formed between an upper side of the input box and an upper edge of the content in jth column.
As another example, the first touch operation is a swiping from down to up, the first operating direction is from down to up, the first operating distance is S1, the width of the input box in the up-down direction is H, the preset percentage is 20%, and the line of the operation starting point of the first touch operation is the jth column. When S1<H×20%, the content in the jth column are moved by S1 along the direction from down to up. When S1≧H×20%, the content in the jth column are moved by H×20% along the direction from down to up. As a result, a blank space is formed between a lower side of the input box and a lower edge of the content in the jth column.
In some embodiments, content in a range from the nth line above to the nth line below the line containing the operation starting point of the first touch operation may be determined as the target content, where n is a preset positive integer. In this scenario, at S102, the content in these (2n+1) lines are entirely moved by a distance corresponding to the first operating distance along the first operating direction.
At S103, when a second touch operation associated with the blank space is detected, the cursor is placed at a position in the blank space (such position is also referred to as a “cursor position”). The cursor position may be any position in the blank space or an operating position of the second touch operation in the blank space.
As shown in
At S202, when the second operating direction of the third touch operation is opposite to the first operating direction of the first touch operation, the target content is moved by a distance corresponding to the second operating distance along the second operating direction to reduce the blank space. In some embodiments, when the second operating distance is less than a distance (length) of the blank space, the target content is moved by the second operating distance along the second operating direction. When the second operating distance is not less than the distance of the blank space, the target content is moved by the distance of the blank space along the second operating direction.
For example, the first touch operation is a swiping from left to right, the third touch operation is a swiping from right to left, the distance of the blank space between the left side of the input box and the left edge of the target content is D1, and the second operating distance of the third touch operation is S2. When S2<D1, the target content is moved by S2 along the direction from right to left. When S2≧D1, the target content is moved by D1 along the direction from right to left.
As another example, the first touch operation is a swiping from right to left, the third touch operation is a swiping from left to right, the distance of the blank space between the right side of the input box and the right edge of the target content is D1, and the second operating distance of the third touch operation is S2. When S2<D1, the target content is moved by S2 along the direction from left to right. When S2≧D1, the target content is moved by D1 along the direction from left to right.
As another example, the first touch operation is a swiping from up to down, the third touch operation is a swiping from down to up, the distance of the blank space between the upper side of the input box and the upper edge of the target content is D1, and the second operating distance of the third touch operation is S2. When S2<D1, the target content is moved by S2 along the direction from down to up. When S2≧D1, the content is moved by D1 along the direction from down to up.
As another example, the first touch operation is a swiping from down to up, the third touch operation is a swiping from up to down, the distance of the blank space between the lower side of the input box and the lower edge of the target content is D1, and the second operating distance of the third touch operation is S2. When S2<D1, the target content is moved by S2 along the direction from up to down. When S2≧D1, the target content is moved by D1 along the direction from up to down.
As shown in
For example, in the case that the first touch operation is an operation from left to right, a bubble is added at the end of the target content. The part of the target content that exceeds the right side edge of the input box after the target content is moved is added into the bubble.
Moreover, when the space between the side of the input box and the side edge of the target content in the input box is reduced, a corresponding part of content in the temporary display box, that would enter the display range of the input box, is removed out of the temporary display box.
In some embodiments, instead of being placed in the temporary display box, the corresponding part that exceeds the display range of the input box can be moved to a next line in the input box.
S304 of the method 300 is similar to S103 of the method 100, and thus detailed descriptions thereof are omitted here.
At S305, when additional content is entered at the position of the cursor, a corresponding part of the target content, that exceeds the display range of the input box as a result of adding the additional content, is moved into the temporary display box for display. In some embodiments, the temporary display box may be a bubble.
In some embodiments, instead of being placed in the temporary display box, the corresponding part that exceeds the display range of the input box can be moved to the next line in the input box.
At S306, when content is deleted from the position of the cursor, a corresponding part of the content in the temporary display box, that could enter the display range of the input box as a result of the content deletion, is removed out of the temporary display box.
In some embodiments, instead of the approach described in the paragraph immediately above, when content is deleted from the position of the cursor, a corresponding part of the content in the next line in the input box, that could move into the line of the cursor as a result of the content deletion is removed, out of the next line.
An exemplary application method 400 consistent with embodiments of the present disclosure is described below in connection with
As shown in
At S402, the content of the ith line are moved by a distance corresponding to the first operating distance from left to right to form a blank space between a left side of the input box and a left edge of the content of the ith line. In some embodiments, as described above, the distance by which the content is moved is determined according to not only the first operating distance, but also the preset distance, which may be defined by the width of the input box and the preset percentage.
For example, the first operating distance of the first touch operation is S1, the width of the input box is W, and the preset percentage is 20%. When S1<W×20%, the content of the ith line is moved by S1 along the direction from left to right. When S1≧W×20%, the content of the ith line is moved by W×20% along the direction from left to right.
At S403, a bubble is added in the touch screen, and a part of the content of the ith line that exceeds the right edge of the input box is added into the bubble.
At S404, when a click operation in the blank space between the left side of the input box and the left edge of the content of the ith line is detected, the cursor is positioned at the position where the click operation occurs (such position is also referred to as “click position”).
Consistent with the present disclosure, after the cursor is positioned at the click position, the user may enter additional content at the position of the cursor or delete content from the position of the cursor. These two scenarios are described below in S405 and S406.
At S405, when additional content is added at the position of the cursor, a corresponding part of the target content, that exceeds a display range of the input box as a result of adding the additional content, is added into the bubble for display.
At S406, when content is deleted from the position of the cursor, a corresponding part of the content in the bubble, that enters the display range of the input box as a result of the content deletion, is removed out of the bubble.
Regardless of whether additional content is added at or content is deleted from the position of the cursor, at S407, when a third touch operation associated with the content is detected, a second operating direction and a second operating distance of the third touch operation are determined. For example, the second operating direction of the third touch operation is from right to left.
At S408, when the second operating direction of the third touch operation is opposite to the first operating direction of the first touch operation, the content is moved by a distance corresponding to the second operating distance along the second operating direction to reduce the blank space.
For example, the blank space formed between the left side of the input box and the left edge of the content of the ith line is D1, and the second operating distance of the third touch operation is S2. When S2<D1, the content of the ith line is moved by S2 along the direction from right to left. When S2≧D1, the content of the ith line is moved by D1 along the direction from right to left.
At S409, a corresponding part of the content in the bubble, that enters the display range of the input box as a result of moving the content of the ith line, is removed out of the bubble.

In some embodiments, a first operating direction of the first touch operation is consistent with an alignment direction of the target content. The first moving module 52 is configured to move the target content by a distance corresponding to the first operating distance along the first operating direction to form a blank space between a side of the input box and a side edge of the content. The positioning module 53 is configured to, when a second touch operation associated with the blank space is detected, position the cursor at the cursor position.
The second detection module 61 is configured to, when a third touch operation associated with the target content is detected, determine a second operating direction and a second operating distance of the third touch operation. The second moving module 62 is configured to, when the second operating direction is opposite to the first operating direction, move the target content by a distance corresponding to the second operating distance along the second operating direction to reduce the blank space.
The first addition module 71 is configured to add a temporary display box in the display interface of the touch screen and add a part of the target content that exceeds a display range of the input box as a result of moving the target content into the temporary display box for display. The second addition module 72 is configured to, when adding additional content at the position of the cursor, add a corresponding part of the target content, that exceeds the display range of the input box as a result of adding the additional content, into the temporary display box for display.
The first linefeed module 81 is configured to shift a part of the target content that exceeds the display range of the input box after the target content is moved to a next line in the input box. The second linefeed module 82 is configured to, when adding content at the position of the cursor, shift a corresponding part of the content in the line of the cursor, that exceeds the display range of the input box caused by the additional content, to the next line in the input box.
In some embodiments, the first moving module 52 includes a first moving submodule and a second moving submodule. The first moving submodule is configured to, when the first operating distance is less than a preset distance, move the target content by the first operating distance along the first operating direction. The second moving submodule is configured to, when the first operating distance is not less than the preset distance, move the content by the preset distance along the first operating direction. In some embodiments, the preset distance equals a product of a width of the input box in the first operating direction and a preset percentage.
