I’m using a 800x480 display. The main window contains a background image and some texts and buttons. I’m using a (self made) pop-up window to display a message. In order to hide the pop-up window I’m using Mainwindow.Invalidate() to redraw the mainwindow, but this will take some seconds.
Is it possible to save the area of the main window under the pop-up window before showing it and redraw that later to hide it. This could make hiding a lot quicker.
