Ignore mouse input

[kneksacke]

I have a window in sfml its transparent. i want to be able to click behind it (its topmost window)
is it possible to do this? i don't mind using windows.h its just a personal program.

i want to make a screen overlay for my self.


Code i use for transparent window
   

SetWindowLong(window.getSystemHandle(), GWL_STYLE, WS_POPUP | WS_VISIBLE);
DwmExtendFrameIntoClientArea(window.getSystemHandle(), &margins);

You can simply choose to ignore the mouse event.
Maybe there's a hacky WinAPI way, but I wouldn't know of that.

You'll have to modify SFML or attach your own message queue in addition to changing the window style. More information here.

I suppose the problem here is allowing the window underneath to receive the event as if the window didn't exist. If the "overlay" is on top of a window of your own, you can work out a work to communicate between the two windows.
