s101, instantiating a toolbar.
When an application is launched, the main program of the application may display the target window and instantiate the toolbar.
S102, when a user clicks an erasing tool in the toolbar, the toolbar creates a mask.
S103, when the mask layer acquires the simulated mouse event, mouse information is sent to the main program.
The mask layer can acquire mouse information from the simulated mouse event.
S104, the main program forwards the mouse information to the target window.
In the method shown in fig. 1, the cover layer is required to send the mouse information to the main program, and then the main program sends the mouse information to the target window, namely, two times of data communication are required to send the mouse information to the target window, so that the time delay for providing the mouse information to the target window is larger, the performance loss is serious, the erasing efficiency is reduced, and a huge code volume is required to realize the erasing function.
Fig. 2 shows a flowchart of a handwriting erasing method according to an embodiment of the present application. The method comprises the following steps:
s201, the first mask layer responds to the first operation and notifies the target window to start an erasing mode, the first mask layer is arranged on the upper layer of the target window, and the first mask layer comprises a toolbar.

When the first mask layer responds to the first operation and notifies the target window to start the erasing mode, the target window can be enabled to determine the data or operation received subsequently, and handwriting in the target window can be erased.
In some embodiments, the first cover layer may cover at least a partial area of the target window. In some embodiments, as shown in fig. 3, the first cover layer may cover an area of a preset size of the edge of the target window. It will be appreciated that the embodiment of the present application is not limited to the position and size of the first mask.

It will also be appreciated that in actual practice, the first operation may be another type of operation, such as a voice command "on erase mode".
In some implementations, the target window can be a window that includes handwriting to be erased. For example, the target window may be a window of curriculum software that may present courseware and handwriting written by a user such as a teacher. For another example, the target window may be a window of web conferencing software that may present a conference interface and handwriting written by users such as conferees. In some implementations, the target window can include a World Wide Web (Web) page.
In some implementations, the target window can be notified to turn on the erase mode by a window handle (Handle to A Window, HWND) of the target window.
Wherein the window handle of the target window may be used to identify the target window. And it will be appreciated that in practical applications, the window handle may be replaced with other information that identifies the target window.

The second mask layer directly provides the mouse information for the target window, so that performance loss such as time delay for providing the mouse information for the target window can be reduced, data communication times and code volume for realizing an erasing function are reduced, and the erasing efficiency is improved.
In some implementations, the second mask layer can correspond to a target window. In some embodiments, the second mask may cover at least a partial region of the target window, so that input mouse information for erasing handwriting of the target window in the at least partial region can be acquired through the second mask. In some embodiments, the second cover layer may cover an area in the target window for writing.
In some embodiments, the first skin may be another skin at the same level as the second skin, or the first skin may be the same skin as the second skin. In some embodiments, the first and second cover each cover a different region of the target window. In some embodiments, as shown in FIG. 3, a first overlay covers an edge region of the target window, a toolbar may be included in the first overlay, and a second overlay covers other regions of the target window other than the first overlay, all for the user to write handwriting. It is understood that in practical applications, the first cover layer and the second cover layer may have other positional relationships.
In some implementations, the mouse information may include at least one of coordinate information and status information. Wherein the coordinate information may be used to indicate a position of the mouse in the desktop, and the status information may be used to indicate an operation status of the mouse. In some embodiments, the status information may indicate at least one of whether at least one button on the mouse is pressed, whether a wheel of the mouse is toggled, and whether a trackball of the mouse is toggled. It will be appreciated that in actual practice, the mouse information may include more or less mouse-related information.
In some embodiments, the electronic device includes a mouse, and the user may input the mouse information by dragging the mouse or pressing a button on the mouse, and accordingly, the second mask layer may obtain the mouse information from the mouse. In some embodiments, the electronic device includes a touch screen, and the user may input mouse information on the touch screen via a finger or a stylus, and accordingly, the second cover layer may receive the mouse information from the touch screen, or may obtain the mouse information from the touch screen and the stylus. It will be appreciated that in practical applications, the second mask layer may also obtain the mouse information from other input devices.
In some embodiments, the second skin may be created before mouse information is acquired through the second skin. In some embodiments, in response to the first operation, a second mask may be created and an erase mode may be turned on to the notification target window, and then mouse information may be acquired through the second mask.
In some embodiments, a simulated mouse event may be sent to the target window through the second skin, the simulated mouse event including mouse information. In some embodiments, the PostMessage method may be invoked by the second mask layer to send the simulated mouse event to the target window. In some implementations, the simulated mouse event may be a simulated event generated based on mouse information. In some implementations, mouse information can be sent to the target window based on the window handle of the target window through the second mask. In some implementations, the mouse information can be sent to the target window based on the window handle of the target window, and the window handle of the target window can be provided to the second mask.

In some embodiments, the second cover may inform the target window to close the erase mode in response to the second operation, so that the user may continue writing, drawing, and other operations in the target window.
Wherein the second operation may be for turning off the erase mode. In some embodiments, the second operation may include closing or clicking the erasure tool (such as a rubber button) again. Of course, in practical applications, the second operation may be another type of operation, for example, the second operation may be a voice command "turn off erase mode".
In some implementations, the target window can be notified of the erase mode closing by the window handle of the target window.
In the embodiment of the application, the first mask layer may inform the target window to start the erase mode in response to the first operation. The second mask layer is a transparent rendering layer positioned on the upper layer of the target window, so that input mouse information can be obtained through the second mask layer, the mouse information is sent to the target window through the second mask layer, and the erasing operation indicated by the mouse information is executed through the target window, so that handwriting in the target window is erased, and the writing and drawing contents in the target window can be updated or corrected conveniently.
