VirtualTreeView Hover over Node

[Weitentaaal]

Hello guys,

so i have a TreeView with some Nodes and i wanted to create an Event which gets fired when some1 Hovers over a Node.

Didn't find anything about an onhover event (maybe i could use on enter and onexit node). And after some1 hovers over a Node

a Text will get displayed.

is this possible ? when yes how ?

If I understood you correctly, you wish to show some kind of hint. For this you have the OnGetHint event.

Code: Pascal  [Select][+][-]

1. procedure TForm1.VSTGetHint(Sender: TBaseVirtualTree;
2.   Node: PVirtualNode; Column: TColumnIndex;
3.   var LineBreakStyle: TVTTooltipLineBreakStyle; var HintText: String);
4. begin
5.   //..
6. end;

You must set ShowHint to true and HintMode to hmHint.
