[0005] The present application provides a page splitting method, including, after receiving an instruction to add a split line, obtaining the position information of the added split line and adding it to a split line record; wherein the position information includes the page number of the current page, the coordinate value and direction of the added split line; after receiving an instruction to split, splitting is performed according to the position information of the split line stored in the split line record.
[0006] Compared with the related art, the present application adds the split line information to the split record. When the user operates on the page, the split line information in the record can be directly retrieved, so that the user can perform various operations on the page without interrupting the current operation, reducing the user's learning burden on the function.
[0007] In an exemplary embodiment, the present application directly splits pages in the original editor; it is designed to split directly in the current document, and the user can directly perform real-time page splitting operations on the current page without interrupting the current operation and jumping to a new interface to perform the splitting operation; the user's learning burden on the function is reduced, and the splitting function display method is more user-friendly.

[0022] like Figure 1 As shown, the page splitting method of the embodiment of the present application includes the following operations:
[0023] S1. After receiving an instruction to add a split line, obtain the position information of the added split line and add it to the split line record; wherein the position information includes the page number of the current page, the coordinate value and direction of the added split line;
[0024] S2. After receiving an instruction to split, split according to the position information of the split line stored in the split line record.
[0025] In an exemplary embodiment, the instruction to add a split line may be that the user clicks a button to add a split line, or the user clicks and drags from the edge of the page after entering the function of splitting pages, or the user right-clicks and selects Add.
[0026] In an exemplary embodiment, the direction in the acquired position information of the added split line is a current default direction or a direction selected by a user; the direction includes a horizontal direction and a vertical direction.
[0027] Exemplarily, in one way, when the user clicks the horizontal / vertical add button or menu item, the direction is selected. In another way, when the user adds a split line by dragging from the top edge of the page downward or from the bottom edge of the page upward, the direction is horizontal, and when the user adds a split line from the left edge of the page to the right, or from the right edge to the left, the direction is vertical.
[0028] In an exemplary embodiment, the coordinate value in the position information of the added split line obtained is the coordinate value of the current click position. For example, if the direction is horizontal, only the vertical coordinate of the click position needs to be obtained; if the direction is vertical, only the horizontal coordinate of the click position needs to be obtained.
[0029] For example, when the mouse moves, the coordinate value can be obtained in real time. When the left mouse button is clicked on one of the positions on the page, the position is considered to be the "add split line" area, and the message of "add split line" being triggered is captured, and then the bound slot function is triggered. After reaching the slot function, the page coordinate data of the current page is obtained through the saved page object doc and written into the list list, the interface is refreshed, and then all the list coordinate values are redrawn through the qt library drawLine function.
[0030] In another exemplary embodiment, the coordinate values in the acquired position information of the added splitting line are preset coordinate values, or are coordinate values calculated in a preset manner.
[0031] Assuming that the predetermined coordinate value is the coordinate value of the center line, the coordinate value of the center line can be saved in advance, or the coordinate of the center line can be calculated according to the coordinates of the four corners of the page.
[0032] For example, after triggering "Add Split", the page coordinate values stored in the memory can be obtained. The coordinate value of the upper left corner is QPoint point1 (x1, y1), and the coordinate value of the lower right corner is QPoint point2 (x2, y2). Then, the coordinates of the two middle points can be calculated by the algorithm as point3 = QPoint ((x2-x1) / 2, y1), point4 = QPoint ((x2-x1) / 2, y2). Then, drawLine can draw the "middle line" in the middle of the page, realizing the half-split of the page.
[0033] For example, when you click the "Add horizontal dividing line" button, it is added at the horizontal center of the current page by default. When you click the Add button N times, N horizontal dividing lines are added; when you click the "Add vertical dividing line" button, it is added at the vertical center of the current page by default. When you click the Add button N times, N horizontal dividing lines are added.
[0034] In an exemplary embodiment, the method further includes operation S3: when a split line is selected and a drag operation is detected, the coordinate value of the selected split line after movement is determined according to the direction and distance in which the selected split line is dragged, and the position information of the selected split line is updated in the split line record.
[0035] In an exemplary embodiment, determining the coordinate value of the selected splitting line after it is moved according to the direction and distance in which the selected splitting line is dragged in operation S3 includes the following operations:
[0036] S31, when the selected split line is dragged horizontally, if the distance between the longitudinal coordinate value of the position at which the split line stops and the longitudinal coordinate value of the longitudinal center line of the current page is within a predetermined range, the longitudinal coordinate value of the longitudinal center line is used as the longitudinal coordinate value of the split line after the split line moves;
[0037] S32. When the selected splitting line is dragged vertically, if the distance between the horizontal coordinate value position when it stops and the horizontal coordinate value of the horizontal center line of the current page is within a predetermined range, the horizontal coordinate value of the vertical center line is used as the horizontal coordinate value of the splitting line after it moves.
[0038] Example 1: When the mouse selects the split line, during the dragging process, the new separation point position is calculated.
[0039] Example 2: When the added split line is the center line, when the split line is moved, the page coordinate value stored in the memory is obtained as the starting point QPoint point1 (x1, y1), the lower right corner coordinate is QPoint point2 (x2, y2), and the value fOffsets entered by the user UI is obtained. Then, the coordinate values to be drawn can be calculated as QPoint point3 ((x1+fOffsets), y1), QPoint point4 ((x1+fOffsets), y2) These two coordinate values can achieve accurate setting of the split line position.
[0040] In an exemplary embodiment, the method also includes operation S4, when an instruction to cancel a split line is received, searching the split line record for information of the last added split line, and changing the display parameters in the found information to invisible; the split line record includes information of each split line in the current document; wherein the information of a split line includes position information and display parameters of the split line, and the display parameters are used to indicate whether the split line is visible.
[0041] For example, when Undo is clicked, we can set the display bShow of the next item in the list to false, refresh the interface, and re-read the list information. When bShow == false, no drawing is performed, thus realizing the "retreat" function.
[0042] In an exemplary embodiment, the method further includes operation S5, when receiving an instruction to delete a split line, searching the split line record for information corresponding to the selected split line according to the position information of the selected split line, and changing the display parameters in the found information to invisible.
[0043] In an exemplary embodiment, the method further includes operation S6: when an instruction to delete all split lines is received, changing the display parameters in the information of all split lines in the split line record to be invisible or deleting the records of all split lines.
[0044] For example, during the movement of the mouse, the real-time coordinate value can be obtained, and the coordinate comparison is continuously performed in the onmouse function. After the left mouse button is clicked, the issued system event can be obtained. At this time, by comparing the coordinate value, it is determined whether the current coordinate is on the dotted line that has been drawn, and true is returned. At this time, click "Delete Splitting Line", which can trigger the bound delete slot function. After running to the slot function, the selected "split line" coordinate value is deleted from the saved list, and then the interface is refreshed. The coordinate values in all lists are redrawn through the qt library drawLine function, and the effect of "deleting the split line" is achieved.
[0045] In an exemplary embodiment, the method also includes operation S7, when a preview indication is received, searching the split line information corresponding to the current page in the split line record according to the page number of the current page or the specified page, or searching the split line information of all pages of the current document in the split line record; according to the found split line information, the split line with a display parameter as visible is displayed on the preview interface.
[0046] In an exemplary embodiment, in the preview interface, you can view only the current page, or you can view multiple or all pages.
[0047] For example, when adding a split line, the coordinates of the split line will be saved in a list list, which actually contains the page number flag nFlag, whether to show or hide information bShow, and the split line coordinate values contained in each page object. From the "page range" UI, we can get the information set by the user, including the set page range, so that we can compare the page number value. When the comparison is equal, we set bShow to true, otherwise set it to false. Then refresh the interface and redraw all lists. If bShow is equal to true, call drawLine to draw the "split line", so that the split effect can be previewed on the page set by the user.
[0048] In an exemplary embodiment, the method further includes operation S10, when a split line is selected, triggering the display of one or more moving bars around the split line in the corresponding direction of the current page according to a preset distance value; wherein each of the moving bars is used to indicate the position to which the selected split line can be adjusted. When the split line is horizontal, horizontal moving bars are displayed above and below the split line, and when the split line is vertical, vertical moving bars are displayed on the left and right of the split line.
[0049] For example, Figure 2 As shown, the orange parts on the four sides ( Figure 2 The four gray areas in the middle) are by default clicked and long pressed by the mouse to drag, and the effect of the mouse passing over can be dragged out to draw the corresponding horizontal and vertical dividing lines. Each time you drag, you can drag a dividing line. The four diagonal areas are gray areas, and the corresponding dividing lines cannot be dragged out. The drag operation is invalid. When the page is enlarged beyond the application window, the hot zone function that can drag out the splitting line stays on the four sides of the application window.
[0050] In an exemplary embodiment, the preset distance value may be input by the user this time, or may be a preset value.
[0051] like Figure 3As shown, the present application also provides a page splitting device, including a processor and a memory, wherein the memory stores a program for page splitting; the processor is used to read the program for page splitting and execute any one of the methods described above.
[0052] It will be appreciated by those skilled in the art that all or some of the steps, systems, and functional modules / units in the methods disclosed above may be implemented as software, firmware, hardware, and appropriate combinations thereof. In hardware implementations, the division between the functional modules / units mentioned in the above description does not necessarily correspond to the division of physical components; for example, a physical component may have multiple functions, or a function or step may be performed by several physical components in cooperation. Some or all components may be implemented as software executed by a processor, such as a digital signal processor or a microprocessor, or implemented as hardware, or implemented as an integrated circuit, such as an application-specific integrated circuit. Such software may be distributed on a computer-readable medium, which may include a computer storage medium (or non-transitory medium) and a communication medium (or temporary medium). As known to those skilled in the art, the term computer storage medium includes volatile and non-volatile, removable and non-removable media implemented in any method or technology for storing information (such as computer-readable instructions, data structures, program modules, or other data). Computer storage media include, but are not limited to, RAM, ROM, EEPROM, flash memory or other memory technology, CD-ROM, digital versatile disks (DVD) or other optical disk storage, magnetic cassettes, magnetic tapes, magnetic disk storage or other magnetic storage devices, or any other medium that can be used to store the desired information and can be accessed by a computer.
