29.3.3.1 Basic Parameters

These frame parameters give the most basic information about the frame. title and name are meaningful on all terminals.

display
The display on which to open this frame. It should be a string of the form "host:dpy.screen", just like the DISPLAY environment variable.


display-type
This parameter describes the range of possible colors that can be used in this frame. Its value is color, grayscale or mono.


title
If a frame has a non-nil title, it appears in the window system's title bar at the top of the frame, and also in the mode line of windows in that frame if mode-line-frame-identification uses ‘%F’ (see %-Constructs). This is normally the case when Emacs is not using a window system, and can only display one frame at a time. See Frame Titles.


name
The name of the frame. The frame name serves as a default for the frame title, if the title parameter is unspecified or nil. If you don't specify a name, Emacs sets the frame name automatically (see Frame Titles).

If you specify the frame name explicitly when you create the frame, the name is also used (instead of the name of the Emacs executable) when looking up X resources for the frame.

explicit-name
If the frame name was specified explicitly when the frame was created, this parameter will be that name. If the frame wasn't explicitly named, this parameter will be nil.
