How can I show a PopupMenu under the mouse cursor?

Applies To: C++Builder 1 or higher

1.

  Start a new project using File | New Application.

 

2.

  Add a PopupMenu. Insert some sample items.

 

3.

  Double-click the OnMouseDown event of your form:

 

void __fastcall TForm1::FormMouseDown(TObject *Sender,

    TMouseButton Button,TShiftState Shift, int X, int Y)

{

    TPoint p = ClientToScreen(Point(X, Y));

    PopupMenu1->Popup(p.x, p.y);

}

 

The Popup method allows you to bring up the PopupMenu. The coordinates used by this method are screen-related and you have to use the ClientToScreen procedure.
