Drag image not visible on Mac

[corpusgemini]

Hello there,

I am a not very experienced hobby programmer and I am writing a cross platform application in which I want to drag and drop items from one side to another. The drag and drop itself is working fine, but there is no drag image visible. I've been trying to find out what can be the case but I can't find any reason why it doesn't work.
There is an example program in Lazarus, and when I run it on WinXP, the drag image is visible, but not under Mac.

Is this feature not implemented in Mac, or do I need to do anything specific?

Thanks in advance,
Tony

You cannot draw outside paint routines on MacOS. The only solution I found was to switch to Qt framework.
