Problems solved by technology

However, this method of marking the window as a Layered Window to realize the shadow display of the window frame has certain disadvantages: Layered Window will occupy a large amount of memory, and the memory usage will increase proportionally with the increase of the window area; the blooming of Layered Window The performance is poor, and the animation effect realized in Layered Window will be more difficult to achieve the ideal frame rate than in non-Layered Window under the same circumstances.

Embodiment approach

[0030] As a specific implementation manner, the window frame shadow display method further includes the following steps: monitoring the screen coordinate change of the main window, and adjusting the screen coordinate of the slave window according to the monitored coordinate change amount. When the user changes the position of the main window on the display screen, that is, changes the screen coordinates of the main window, this embodiment monitors the event of the change of the screen coordinates of the main window, and adjusts the screen of the slave window according to the monitored change in the coordinates of the main window. Coordinates, for example, take the upper left corner of the display screen as the coordinate origin, the horizontal direction to the right as the positive direction of the x-axis, and the direction perpendicular to the x-axis as the positive direction of the y-axis to establish a coordinate system. WindowAPI listens to the screen coordinates of the main...

Abstract

The invention relates to a window border shade display method and device. The method includes the steps: creating slave windows spliced to peripheral borders of a master window which is a non-Layered Window, wherein the slave windows are Layered Windows; adjusting the size of the slave windows according to the size of the master window, and adjusting screen coordinates of the slave windows according to the screen coordinates of the master window; computing pixel transparency of the slave windows, and displaying the slave windows according to computing results. By setting the master window of a display interface used for normally presenting software as the non-Layered Window and the slave windows spliced to the peripheral borders of the master window as the Layered Windows, border shade display effect of the master window is realized with the aid of the slave windows, and memory usage of the system is reduced on the whole.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a window frame shadow display method and device. Background technique [0002] At present, in the operating system, the frame shadow effect of the window is often realized by making the edge area of ​​the window appear translucent. The application programming interface (Win32API) of the bit platform sets the window as a Layered Window (layered window), and draws a translucent shadow effect in the edge area of ​​the window. However, this method of marking the window as a Layered Window to realize the shadow display of the window frame has certain disadvantages: Layered Window will occupy a large amount of memory, and the memory usage will increase proportionally with the increase of the window area; the blooming of Layered Window The performance is poor, and the animation effect realized in the Layered Window will be more difficult to achieve the ideal frame rate than in...
