Remarks

System menus are used to provide a series of standard operations, such as moving, closing, and resizing windows. Different GUI conventions dictate what items should be added to the system menu. An application window can have a system menu by calling AppWindow:EnableSystemMenu(). Using the Window:MenuCommand() event handler, the system menu can be manipulated in the same way as a menu. To access a window's system menu, you must first enable the system menu with a call to AppWindow:EnableSystemMenu(). You can then use the system menu it returns.

Examples

The following example adds an About item to a system menu:

Copy

1oSysMenu := oMyWin:EnableSystemMenu()
2oSysMenu:AppendItem(MENUSEPARATOR)
3oSysMenu:AppendItem(IDM_ABOUT,"About...")
4oSysMenu:RegisterItem(IDM_ABOUT,HyperLabel{#About})
