Update "Grab Desktop at Start"

[TreyM]

Is it possible to re-grab the desktop? For example:

I have a splash screen. It grabs desktop to show transparency. I open a web browser (or any other app) then re focus the splash screen. It still shows the desktop and not the white background of the web browser. Is it possible to update this at runtime?

I know this is an old thread, but I struggled with this too. Window Shape object, Kiosk Object and the Kernel Object didn't help me. I wanted an invissible window with non transparent objects in it. The object that did it for me was: Window Transparency Object. Not sure if it is for dev. only, but all I had to do was to set the Alpha Channel to my window background colour at the start of the frame. That is it.
This will give the excact same effect as grabbing the desktop at start, but it will "update" to whatever background you have in Windows. (Not really what it is doing, but for sake of explination - It actually makes your window transparent)

Hope this helps someone else.

The Surface object also can grab windows or the whole desktop.
So you can fake transparency and be able to add some calculations or effects.
In some cases this could be very useful too.
