## system-menu

Arguments: basic-pane

If this boolean property is true, then the window named by the argument will have a small button on the left side of its titlebar that invokes a standard menu of commands for minimizing, closing, etc. the window.

The system-menu property may not be changed on an existing window, and must instead be specified with the inspector when designing a window (using a form) or with the :system-menu initarg of make-window. (It can be changed using the inspector when designing a form but not for a running window or control, either in the IDE or in an application.)

### GTK Note

For child windows, we have not yet implemented the menu that is shown when clicking on the icon, though the icon is drawn. For a top-level window, this property will have an effect only if the window manager decides to honor it.
