Hey :),

is it possible to get VirtualTreeView-New "running" on Mac?

I tried it myself, but the TreeView is just empty, even if I add some Nodes, nothing is gonna painted on it

Best Regards

Try invalidate the tree. I'm not sure about the TreeView implementation details, but drawing on a control canvas is allowed only inside OnPaint event. But It's more likely unimplemented API for Carbon.

It seems that everything is painted in Paint; , it didn't helped to Invalidate it from Outside nor to Invalidate on LMPAINT - Message

Any other Suggestions? :(

Could you check mantis for the bug report? If i remember correctly, there's a report about it.

The WMPAINT-Procedure / LMPAINT-Message don't sends a "PaintRect" in its Message on Mac, so the Rect, what VST should paint again is everytime Rect(0,0,0,0) -> Nothing is painted.

Thats why it add in procedure TBaseVirtualTree.Paint:
{$IFDEF Darwin}
    FUpdateRect := ClientRect;
{$ENDIF}

Now its painted at least also on Darwin :)
