I have 2 questions:

One:
In a TreeView control, there doesn't seem to be an 'ItemDblClick' event.
There is an 'ItemClick' event and a 'DblClick' event, but how do I find out if a user double clicked on an item? I tried combining ItemClick and DblClick with no success

Two:
Is there a way to blit with a specified transparent color?

If possible, please supply code.
Thanks.
