Forms Delphi

Title: Detecting Right Clicks on your forms title bar
Question: how do I detect a right click and/or kill the menu for my title bar?
Answer:
This is a relatively simple problem, you just need to know the correct windows message to trap. Here's how to do it:
declaration:
procedure WMNCRButtonDown(var Msg : TWMNCRButtonDown); message WM_NCRBUTTONDOWN;
definition:
procedure TMainFrm.WMNCRButtonDown(var Msg : TWMNCRButtonDown);
begin
if (Msg.HitTest = htCaption) then
begin
(your code here & the next line kills the menu)
Msg.HitTest := 0;
end
else
inherited;
end;
Additional Info:
NC stands for non-client
WMNCLButtonDown or WMNCMButtonDown may be used instead for left or middle button respectively
No WM_NCRBUTTONUP message is generated, only a WM_RBUTTONUP when the mouse is release
This has been tested with Delphi 5 on win2k, 95, 98 and NT4. It should work also fine with earlier versions of delphi, but these have not been tested.
