Determines whether the pop-up menu appears automatically when the user clicks the right mouse button.
property AutoPopup: Boolean;
__property Boolean AutoPopup;
Set AutoPopup to true to cause the pop-up menu to appear automatically when the user clicks the right mouse button on a control that has the pop-up menu specified as its PopupMenu property. The application key present on keyboards specifically designed for 32-bit Windows will also show this menu when pressed.
Set AutoPopup to false if the appearance of the pop-up menu should be controlled programmatically. To display a pop-up menu when AutoPopup is false, use the Popup method.
Delphi Examples:
{ This example uses a pop-up menu. When the user presses the mouse button, the pop-up menu appears where the user clicked the mouse: } procedure TForm1.FormCreate(Sender: TObject); begin PopupMenu1.AutoPopup := False; end; procedure TForm1.FormMouseDown(Sender: TObject; Button: TMouseButton; Shift: TShiftState; X, Y: Integer); begin PopupMenu1.Popup(Left + X, Top + Y); end;
