Title: Closing popup menu in system tray application
Question: Sometimes, my popup menu in my tray application does not
close when it loses focus. How can I get it to close?
Answer:
When processing the message to pop up the menu, you need to set the
foreground window, then send a WM_NULL message after the menu popup.
procedure TForm1.WndProc(var Msg : TMessage);
var
p : TPoint;
begin
case Msg.Msg of
WM_USER + 1:
case Msg.lParam of
WM_RBUTTONDOWN: begin
SetForegroundWindow(Handle);
GetCursorPos(p);
PopupMenu1.Popup(p.x, p.y);
PostMessage(Handle, WM_NULL, 0, 0);
end;
end;
end;
inherited;
end;
