According to the plugin's coordinates, set the same as the window background
That is, if the control is at the X1,y1 point, the background image used is also set to the x1,y1 's coordinates when the control is set to the background in the control's actual position.




The so-called control is transparent, and the background of the accusation piece is the same as the large background of the window.


If the control does not move, you can take the background of the corresponding position in the window to make the background of the control, with Setbackgroudpixmap


If the control is movable, it is necessary to re-set the background of the background of the window when it is moved.


The principle is so that you can achieve it yourself.
