Hi everybody. I use WinTree on my form and use xml as node text. Also I've created class implemented IUIElementDrawFilter for colorization text in nodes. But when one node selected -- width of selection rectangle equal width of node text xml but not real text displayed by DrawFilter. How can I resize rectangle of selection for real displayed text? Thanks.

Can you post a screen shot of what this looks like? My guess is that your DrawFilter will also have to draw the focus rectangle. The tree can't possibly know how big the text is when you are drawing it.

I don't see any easy way around this. My guess is you would need to use a CreationFilter either instead of or in addition to your DrawFilter. The CreationFilter allows you to change the size and position of elements.
