Hello,

I have a program in delphi (7 and 2010) with win32 treeview control. How can I add an action to my node?
For example:
I want to play mp3 file when i select node in my treeview.
or
like windows explorer, where if click on a file in left pan, it shows action in right pan.

Thank you

You should check in the OnClick event if the click was realy on an icon. Below an example.

SQL

procedure TForm1.TreeView1Click(Sender: TObject);
var
  P:TPoint;
begin
  GetCursorPos(P);
  P := TreeView1.ScreenToClient(P);
  if (htOnStateIcon in
             TreeView1.GetHitTestInfoAt(P.X,P.Y)) then
    ToggleTreeViewCheckBoxes(
       TreeView1.Selected,
       cFlatUnCheck,
       cFlatChecked,
       cFlatRadioUnCheck,
       cFlatRadioChecked);
end;

Good luck!
