29.3.3.6 Window Management Parameters

The following frame parameters control various aspects of the frame's interaction with the window manager. They have no effect on text terminals.

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
If non-nil, Emacs automatically raises the frame when it is selected. Some window managers do not allow this.


auto-lower
If non-nil, Emacs automatically lowers the frame when it is deselected. Some window managers do not allow this.


icon-type
The type of icon to use for this frame. If the value is a string, that specifies a file containing a bitmap to use; nil specifies no icon (in which case the window manager decides what to show); any other non-nil value specifies the default Emacs 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 ID number which the graphical display uses for this frame. Emacs assigns this parameter when the frame is created; changing the parameter has no effect on the actual ID number.


outer-window-id
The ID number of the outermost window-system window in which the frame exists. As with window-id, changing this parameter has no actual effect.


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.
