My application is fumbling part of the desktop with a window of any application. When someone browses this ball, then on the machine on which the application is running, you need to somehow select the window of the shared application. Now I draw a frame around it using GtkWidget
. But with this frame there are many problems, especially on different DEs (remove the frame if the application is minimized or blocked, change the size of the frame when the window is resized, etc.). Therefore, I want to find an option to somehow select a window. The question is, is it possible to select a window using xlib or gtk (for example, an analogue of the FlashWindowEx function for Windows, or can you somehow change the color of the window frame)?
