As an optional part of another project I would like to render something on my screen above everything else.
Is this possible to do? I have several ideas on how it might work ( below ) but no idea if it is possible. I’d appreciate any pointers or even a flat-out “No, you can’t do that”
My ideas are:
- Un-decorated window with either a transparent fill or filled with the “desktop” below it ( I know some other applications implement transparency this way )
- Window taking up the full screen but is either transparent or filled as above and either ignoring inputs or passing them to the windows beneath
