29.3.3.6 Window Management Parameters

These frame parameters, meaningful only on window system displays, interact with the window manager.

visibility

The state of visibility of the frame. There are three possibilities: nil for invisible, t for visible, and icon for iconified. See Visibility of Frames.

auto-raise

Whether selecting the frame raises it (non-nil means yes).

auto-lower

Whether deselecting the frame lowers it (non-nil means yes).

icon-type

The type of icon to use for this frame when it is iconified. If the value is a string, that specifies a file containing a bitmap to use. Any other non-nil value specifies the default bitmap icon (a picture of a gnu); nil specifies a text icon.

icon-name

The name to use in the icon for this frame, when and if the icon appears. If this is nil, the frame's title is used.

window-id

The number of the window-system window used by the frame to contain the actual Emacs windows.

outer-window-id

The number of the outermost window-system window used for the whole frame.

wait-for-wm

If non-nil, tell Xt to wait for the window manager to confirm geometry changes. Some window managers, including versions of Fvwm2 and KDE, fail to confirm, so Xt hangs. Set this to nil to prevent hanging with those window managers.

sticky

If non-nil, the frame is visible on all virtual desktops on systems with virtual desktops.
