Does someone know how PB is changing the Backgroundcolor of a Window?

Either by replacing the default background brush or in a response to a #WM_ERASEBKGND message.

Code: Select all

SetWindowColor(#Window, Color)

Well, I guess he means internally.

Of the two main options, SetClassLong with a background brush vs. FillRect in response to a #WM_ERASEBKGND message, my sleuthing seems to indicate that it is FillRect. I've no idea what the reasons might be, but I know they think these things out quite thoroughly.

It's realy fill rect. (If u delete the PB Callbacksstuff it's not drawing the background anymore.

I guess that's kind of stupid.
