TPopupMenu is a menu panel that pops up on the screen when the right mouse button is clicked.
TPopupMenu inherits all the properties of TMenu (including the properties of TMenuItem), but has some new methods (procedure PopUp and procedure Close) that define its behavior when invoked.
PopupPoint defines the position of the pop-up menu, usually at the current cursor position.
To use a pop-up menu, first create it with the MenuEditor. Then with the Object Inspector for the control that needs to use the Pop-up, select the property named PopupMenu, and a list box will appear with the names of the available Menus - choose the Pop-up name you want.
TPopupMenu for the Windows platform was modified in LCL version 2.2.6. It no longer uses the highlighted drawing effect when drawing the glyph icon for an enabled menu item. The normal drawing effect is used instead.
