title-bar

Arguments: basic-pane

Returns the value of the title-bar property of the argument. The value of this property should be t if an object should have a title-bar and nil if it should not. Many windows display what looks like a title-bar even when the property is nil but the title-bar in that case will not have any controls (such as a close box).

The title-bar 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 :title-bar 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

It is probably not a good idea to specify nil for the title-bar property of a top-level window on a GTK platform (Linux or Mac), unless you also define a frameless-topmost-p method for the window class that returns true. When title-bar is nil for a top-level window on GTK, the window will have no window manager frame, which can lead to confusion in the X11 world. But a frameless-topmost-p window is a special type where X11 is prepared to handle no window manager frame.
