[news.eclipse.platform.swt] Re: Tooltip on TreeView leaves

[Werner Janjic <werner.janjic@xxxxxxxxxxxxxxxxxxxxxxxxxx>]

Hello!

I've tried both of your suggestions (as you see some days) but I don't
get it how to (simply) add the tool tip to a TreeView - better said - to
a TreeObject (what would be a leave in the tree).

Could you please give me an example implementation of it (see code
example in original post)? I wouldn't be bugging you about this if it
wasn't important, so please excuse me for this.

Thank you many times in advance.

Werner
