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 ?

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][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TForm1.VSTGetHint(Sender: TBaseVirtualTree;  Node: PVirtualNode;
Column: TColumnIndex;  var LineBreakStyle: TVTTooltipLineBreakStyle;
var HintText: String);begin  //..end;
You must set ShowHint to true and HintMode to hmHint.
