Hi Bob.

There doesn't appear to be any font properties we can modify at run-time either.

Sure there are. Its just that the TreeView (like many activeX controls) has a font onject that controls the font. Run your form with the TreeView in it and grab an object reference to the TreeView by using O = SYS( 1270 ) or the code below:

oTree = _Screen.Activeform.otree
onode = otree.selectedItem
*** Make the font on the selected node bold
onode.Bold = .t.
*** Or change its color and make it red
oNode.ForeColor = 255
*** Now change the font for the entire treeView
ofont = otree.font
ofont.Name = 'Comic Sans MS'
*** Make it big
ofont.size = 16
