One of :normal , :maximized , :iconic , :hidden or :full-screen . |
Top level interfaces and dialogs can be manipulated by the user, such as being iconifed or maximized. The program can manipulate these windows too. The generic function top-level-interface-display-state
returns a value that indicates the current state of the interface interface. The following values can be returned:
:normal |
The window is visible and has its normal size. |
:maximized |
The window is visible and has been maximized. |
:iconic |
The window is visible as an icon. |
:hidden |
The window is not visible. |
The window is full screen (only supported on macOS 10.7 and later). This value is only applicable when the window-styles list contains the keyword |
These values can also be passed as the :display-state
initarg when making a top level interface.
In addition, the function (setf top-level-interface-display-state)
can be used to change the state of a top level interface. The value can be set to one of the above, or to :restore
if the current state is :iconic
or :hidden
. When set to :restore
, the state will become :normal
or :maximized
depending on how the interface was visible in the past.
