Alpha transparency compatibility - please test

Trond · Post by **Trond** » Thu May 11, 2006 5:40 pm

I'm making a translucent clock so I want to get some people to test if the clock in it's current version works properly. Actually it's not really a clock yet, it's only a disc. Currently GDI+ is used to load the png images, since when I load them with PB they get sort of white.

( http://www.purebasic.fr/english/viewtopic.php?t=21739 ) Try without gdiplus.dll first, in case you already have it.

Exe file
Required png file
GDI+

Please test:
Your OS
Did you need to download GDI+?
Was there a taskbar button? (Shouldn't be)
Did it ever go in front of other programs? (It should always stick to the desktop)
Does the translucency work correctly?
Even after you click anywhere on the desktop and press F5?
Can you drag the window around?
Does nothing bad happen when you press Alt+Tab?
Did you see any flickering?

Thank you!

my test:
Windows Me
it needed the gdiplus.dll file, bu then it gave an error that user32.dll doesn't have the export function UpdateLayeredWindow

Thank you all for the test. I think the transparency is not supported on Windows 9.x/Me.

Edit: More people can test if they want but it's not strictly necessary. I was worried about F5 on Windows 98, but as the transparency won't work anyways I don't think it's a problem.

Maybe I missed something, but in the given thread there is the source code only, but no PNG file - shouldn't we all use the same PNG files also to get good test results?

Why didn't you post in that thread?

You can use the png file from this thread. Or one of the two posted later in the thread.
