how do i disable window-closing? 1

[sancho1980]

If I have a TForm object, it by default closes when I click on the X of the window, right? There must be a way of disabling that, is there? I was looking like mad for an appropriate property but wasn't able to find it...
Thanx,
Martin

The appropriate "property" is the OnClose event.

The following ignores any clicking on the X.

procedure TForm1.FormClose(Sender: TObject; var Action: TCloseAction);
begin
  action := caNone;
end;

There's also the biSystemMenu property under BorderIcons in the object inspector if you don't want the button at all, but towerbase's way lets you choose.
