syscursor

klaus.s · February 17, 2008

Hi,

for changing the system-cursor I found several examples using LoadCursorFromFile. Searching for LoadCursor the only hit was here:

http://www.autoitscript.com/forum/index.ph...p;hl=loadcursor

(This magnifier is a very nice tool by the way.)

syscursor can change the system-cursor to another built-in cursor or to one stored locally in a cur-file. Only one flaw so far: a built-in cursor has to be sacrified if a custom-cursor is used. Maybe someone has further ideas about that.

Updated version, flaws removed by using CopyIcon (CopyCursor does not work, XP/SP2), attached zip-file includes two cur-files.

Fails with animated cursors.

Clarification: By "fails" I don't mean errors, but animated cursors do not work (they are not animated, only still pictures).

I think you will know how to convert this. It's a delphi example using Animated Cursors

Thanks to all for your comments and feedback. Until now I did not consider these animated cursors and maybe a solution will come up. Because I like this swapping functionality of LoadCursor/SetSystemCursor as already shown in my first version, I added this in my newest version, along with some cleanup.
