In order to adapt to the development of online conferences and facilitate the content display of the online conferences, the functions of the electronic whiteboard are more and more abundant. The existing electronic whiteboard has multiple functions, such as writing, drawing, audio and video playing and the like. The embodiment of the invention provides a form dynamic adjustment method, which is used for dynamically adjusting forms in an electronic whiteboard. The form establishment in the electronic whiteboard can be realized through a menu bar thereof, as shown in fig. 1, a menu schematic diagram of the electronic whiteboard is provided, a terminal user clicks an "intelligent graphic" option in a secondary menu bar, and selects an "insert form" option in the "intelligent graphic", and at this time, the electronic whiteboard jumps out of an attribute box shown in fig. 2. The terminal user can set the column number and the row number of the table to be established according to the requirement, and click to determine to establish the corresponding table.
It should be noted that the form dynamic adjustment method provided by the embodiment of the present invention is suitable for adjusting an electronic whiteboard in a touch electronic device. The menu of the electronic whiteboard shown in fig. 1 and the attribute box shown in fig. 2 are only exemplary, and different electronic whiteboards may have different menu options, which is not limited to this embodiment of the present invention.
Aiming at the problem that the form function in the existing electronic whiteboard is single and cannot adapt to filling content, the form dynamic adjustment method provided by the embodiment of the invention automatically adapts to adjustment of the form boundary along with the movement of the writing track along with the change of the writing track in the form, so that the writing track is prevented from exceeding the form range, and the user experience is improved. As shown in fig. 3, the method specifically includes:
and S101, determining the position of the first contact.
Wherein the first contact point is a starting contact point of the first writing track.
Specifically, the position of the first contact point here may be the position of any point in the electronic whiteboard, and the position thereof may be represented by coordinates, such as (x, y).
It should be noted that the operation of the electronic whiteboard may be realized by touch, and the first contact point may be a point generated when a smart pen or a finger touches a screen of the electronic whiteboard.
Optionally, as shown in fig. 4, before step S102, the method further includes:
s101a, determining the position relation between the first touch point and the table according to the position of the first touch point.
Specifically, the positional relationship between the first contact and the table here means that the first contact is located inside or outside the table. The position relationship between the first contact and the table can be determined by the coordinates, and if the table built in the electronic whiteboard is as shown in fig. 5, the four vertexes are a (x) respectively1，y1)、B(x2，y1)、C(x1，y2) And D (x)2，y2) If x1≤x≤x2And y is1≤y≤y2Then it may be determined that the first contact is inside the table; otherwise, the first contact is located outside the table.
S102, when the first contact point is determined to be located in the table, if the distance between the current contact point and the table boundary is smaller than a first threshold value, the table boundary is adjusted.
And the current contact is the current cut-off contact of the first writing track.
Specifically, the first writing track is composed of a plurality of contact points. When it is determined at step S101a that the first contact point is located inside the table, it may be determined that the first writing track where the first contact point is located is used to fill a certain cell in the table. At this time, as the number of the subsequent contacts of the first contact increases, the first writing track where the first contact is located continuously changes, and when the distance between the current contact of the first writing track and the boundary of the table is smaller than the first threshold, it may be determined that the first writing track is likely to exceed the boundary of the table, and at this time, the boundary of the table may be adjusted to prevent the first writing track from exceeding the boundary of the table.
For example, as shown in fig. 6, the first contact point is located in the first cell of the table, and if it is determined that the distance between the current contact point and the left boundary of the first cell is smaller than the first threshold, the left boundary of the first cell is adjusted to move so that the distance between the current contact point and the left boundary of the first cell is greater than or equal to the first threshold. Of course, the position of the current contact point is also changed continuously with the change of the first writing track, and at this time, the boundary of the first cell needs to be adjusted continuously according to the relationship between the distance between the current contact point and each boundary of the first cell and the first threshold.
It should be noted that the writing track in the embodiment of the present invention is not limited to only text, but may also be other filling content of graphics. Here, the boundary of the table is adjusted in real time with the change of the position of the current touch point, and the adjustment may be stopped when the boundary is adjusted until the distance between the current touch point and the boundary is equal to the first threshold. The first threshold is set to be 30px in the embodiment of the present invention, but of course, a person skilled in the art may set the first threshold to be other values, which is not limited to the embodiment of the present invention.
Further, as shown in fig. 7, step S102 specifically includes:
and if the distance between the current contact and the first boundary is smaller than a first threshold, expanding the first boundary to the direction corresponding to the first boundary.
The first boundary is any boundary of the first cells, the first cells are any cells in the table, and the first contact is located in the first cells.
Specifically, since the first boundary here may be any one of a left boundary, a right boundary, an upper boundary, and a lower boundary of the first cell, further, the step S102 may include:
and S1021, if the distance between the current contact and the left boundary is smaller than a first threshold value, expanding the left boundary to the left.
Specifically, as shown in fig. 8 (a), when the distance between the current contact and the left boundary of the first cell is smaller than the first threshold, the left boundary of the first cell is expanded leftward, so that the expansion of the first cell is stopped when the distance between the left boundary of the first cell and the current contact is equal to the first threshold, and the table shown in fig. 8 (b) can be obtained, where the dotted line is the original position of the left boundary (the first cell).
It should be noted that, when the left boundary of the first cell moves, the left boundaries of all cells in the column of the first cell need to be expanded by the same distance in the same direction, as shown in (b) of fig. 8.
And S1022, if the distance between the current contact and the right boundary is smaller than the first threshold, expanding the right boundary to the right.
Specifically, as shown in (c) of fig. 9, when the distance between the current contact and the right side boundary of the first cell is smaller than the first threshold, the right side boundary of the first cell is expanded rightward, so that the expansion of the first cell is stopped when the distance between the right side boundary of the first cell and the current contact is equal to the first threshold, that is, the table shown in (d) of fig. 9 can be obtained, where the dotted line is the original position of the left side boundary (the first cell).
It should be noted that when the right boundary of the first cell moves, the right boundaries of all the cells in the column of the first cell need to be expanded by the same distance in the same direction, as shown in (d) of fig. 9.
And S1023, if the distance between the current contact point and the upper side boundary is smaller than a first threshold value, expanding the upper side boundary towards the upper side.
Specifically, as shown in (e) of fig. 10, when the distance between the current contact and the upper boundary of the first cell is smaller than the first threshold, the upper boundary of the first cell is expanded upward, and the expansion of the first cell is stopped when the distance between the upper boundary of the first cell and the current contact is equal to the first threshold, so that the table shown in (f) of fig. 10 can be obtained, where the dotted line is the original position of the upper boundary (the first cell).
It should be noted that when the upper boundary of the first cell moves, the upper boundaries of all cells in the row of the first cell need to be expanded by the same distance in the same direction, as shown in (f) of fig. 10.
And S1024, if the distance between the current contact and the lower side boundary is smaller than a first threshold value, expanding the lower side boundary to the lower side.
Specifically, as shown in (g) in fig. 11, when the distance between the current contact and the lower boundary of the first cell is smaller than the first threshold, the lower boundary of the first cell is expanded downward, and the expansion of the first cell is stopped when the distance between the lower boundary of the first cell and the current contact is equal to the first threshold, so that the table shown in (h) in fig. 11 can be obtained, where the dotted line is the original position of the lower boundary (the first cell).
It should be noted that when the lower boundary of the first cell moves, the lower boundaries of all the cells in the row of the first cell need to be expanded by the same distance in the same direction, as shown in (h) of fig. 11.
In another possible implementation manner, if the distance between the current contact and the first boundary of the first cell is smaller than the first threshold, and the distance between the current contact and the second boundary of the first cell is smaller than the first threshold, the first boundary and the second boundary are expanded in the direction corresponding to the first boundary and the second boundary.
Illustratively, as shown in (i) of fig. 12, when the distance between the current contact and the left boundary of the first cell and the distance between the current contact and the lower boundary are both smaller than the first threshold, the left boundary of the first cell is expanded to the left, and the lower boundary is expanded to the bottom, so that the expansion of the first cell is stopped when the distance between the left boundary of the first cell and the current contact and the distance between the lower boundary and the current contact are both equal to the first threshold, and thus the table shown in (j) of fig. 12 is obtained, where dotted lines are the original positions of the left boundary and the lower boundary (the first cell), respectively.
Similarly, when the left boundary of the first cell moves, the left boundaries of all the cells in the column of the first cell need to be extended by the same distance in the same direction; when the lower boundary of the first cell moves, the lower boundaries of all the cells in the row of the first cell need to be expanded by the same distance in the same direction, as shown in (j) of fig. 12.
It should be noted that when the distance between the current contact and the other boundaries in the first cell is smaller than the first threshold, the corresponding boundaries may also be expanded according to the above method, and a side first writing track exceeds the table boundary.
Optionally, after determining that the first contact point is located outside the table according to step S101a, if it is determined that the first writing track is a straight line, as shown in fig. 13, step S101 further includes:
s201, if the first writing track horizontally passes through the table, increasing the row number of the table.
Specifically, the first writing track passing through the table horizontally means that the starting contact point and the ending contact point of the first writing track are both located outside the table, and the contact points between the starting contact point and the ending contact point are distributed inside or outside the table along the horizontal line of the table. When it is determined that the first writing track horizontally passes through the table, a splitting operation may be performed for the table, i.e., splitting the cell passed by the first writing track into two rows.
Illustratively, as shown in (k) of fig. 14, the first writing track horizontally passes through the cells in the first row of the table, and when the first writing track completes writing at the current touch point (i.e., the smart pen or the finger is lifted at the current touch point), the cells in the first row of the table are split into two rows, and the split result may be shown as (l) of fig. 14.
It should be noted that, in this embodiment, since the first writing track is implemented by a smart pen or a finger through touching the electronic whiteboard, the first writing track may fluctuate up and down or left and right, that is, the first writing track may actually be a curve. The curve of the first writing track with the fluctuation range within the second threshold is also regarded as a straight line in the present application, as shown in (k) in fig. 14, and the curve displayed by the first writing track is regarded as a straight line here for splitting the table. The second threshold may be set by those skilled in the art as needed, and is not limited to this embodiment of the present invention.
And S202, if the first writing track vertically passes through the table, increasing the number of columns of the table.
Specifically, here, the first writing track vertically passes through the table similarly to the above-mentioned horizontally passes through the table, and is not described herein again. When it is determined that the first writing track vertically passes through the table, a splitting operation may be performed on the table, that is, the cells passed through by the first writing track are split into two columns.
Illustratively, as shown in (m) in fig. 15, the first writing track vertically passes through the cells in the second column of the table, and when the first writing track completes writing at the current touch point, the cells in the second column of the table are split into two columns, and the split result may be as shown in (n) in fig. 15.
In one possible implementation manner, after determining that the first contact point is located outside the table according to step S101a, if the first writing trajectory is determined to be a curve (the fluctuation range is greater than the second threshold), determining that the first writing trajectory is used for writing characters, graphics, or the like to other positions of the electronic whiteboard, and the first writing trajectory may pass through the boundary of the table and be displayed in the layer above the table; when the first writing track is written, the first writing track can be displayed at other selected positions in the electronic whiteboard. For example, as shown in fig. 16, the first writing track is a curve, and the fluctuation range of the curve is larger than the second threshold, and at this time, the first writing track may cross the boundary of the table, and perform any drawing operation on the table until the contact point is located inside the table, as shown in (p) in fig. 16, or outside the table, as shown in (q) in fig. 16.
Optionally, as shown in fig. 17, the method further includes:
s301, if the distance between the leftmost contact of the first writing track and the left boundary of the first cell is larger than a first threshold value, the first writing track and the right boundary of the first cell are moved to the left.
Wherein the first writing trace is a set of contacts within the first cell.
Specifically, as shown in fig. 18, the first contact point is the leftmost contact point of the first writing track, and as shown in (a) of fig. 18, if the distance between the first contact point and the left boundary of the first cell is greater than the first threshold, the second writing track and the right boundary of the first cell are moved leftward at this time, so that the distance between the first contact point and the left boundary of the first cell is equal to the first threshold, and the adjusted table is shown in (B) of fig. 18.
It should be noted that the first contact point here may be a starting contact point of the first writing track, that is, a contact point when the first writing track is dropped; of course, when the first writing track is a track after the second writing track erases a part of the track, the first contact is actually a certain contact between the start contact and the stop contact of the second writing track, for example, as shown in fig. 19, the second writing track is a curve combining the first writing track and a dotted line in the drawing, the dotted line in the drawing is an erasing part, and after the erasing is completed, the first writing track and the right boundary of the first cell can be moved to the left according to the table adjustment method.
In an alternative implementation, as shown in (a) of fig. 18, when the distance between the first contact and the left boundary of the first cell is greater than the first threshold, the first writing track and the right boundary of the first cell, and all cells on the right side of the first cell may also be moved to the left so that the distance between the first contact and the left boundary of the first cell is equal to the first threshold.
