1. Screen Copy onto Window???
Hello all,
I have a problem that I could'nt find an answer for on
the listserve (prior post), so here goes.
I have a bitmap that has rounded corners and am setting
transparent the outter edges of the bitmap (easy enough)
The problem I have is when I create a Window for this
bitmap to fit ontop of, I want to capture the SCREEN
in the area of my new Window before I paint it
and set the captured Screen ontop of the new Window
before I display my bitmap...
(much like McAfee does in all their newest ware's)
essentially hideing the Window with a portion of the screen
before I drew the Window. If that makes it easier for some.
Here is an attempt (but failure) to do this.
constant
ScreenBuffer = create( Pixmap, "", 0, 50, 50, 500, 400, 0 )
procedure CopyScreenToBuffer()
--myBitmap will start at x = 50 y = 50
copyBlt( ScreenBuffer, 50, 50, Screen )
end procedure
CopyScreenToBuffer()
constant
procedure CopyBufferToScreen()
copyBlt( Screen, 50, 50, ScreenBuffer )
repaintWindow ( Win )
end procedure
onPaint[Win] = routine_id("CopyBufferToScreen")
What am I doing wrong???
Is there a better, smoother, faster way?
preferably one that works. hehe

Hi,
Most application that have irregular shaped windows use the SetWindowRgn
API function. I've attached a library that helps do this. Hope you
find it useful :)
I hope no one minds me sending this file to the list, but it's only 10k
so it should be ok...

Thanks PatRat
This is a perfect substitute for what I wanted.
I sure am glad this List and people like you exist.
