Buffer Parameters

These frame parameters, meaningful on all kinds of terminals, deal with which buffers have been, or should, be displayed in the frame.

minibuffer

Whether this frame has its own minibuffer. The value t means yes, nil means no, only means this frame is just a minibuffer. If the value is a minibuffer window (in some other frame), the frame uses that minibuffer.

This parameter takes effect when the frame is created. If specified as nil, Emacs will try to set it to the minibuffer window of default-minibuffer-frame (see Minibuffers and Frames). For an existing frame, this parameter can be used exclusively to specify another minibuffer window. It is not allowed to change it from a minibuffer window to t and vice-versa, or from t to nil. If the parameter specifies a minibuffer window already, setting it to nil has no effect.

The special value child-frame means to make a minibuffer-only child frame (see Child Frames) whose parent becomes the frame created. As if specified as nil, Emacs will set this parameter to the minibuffer window of the child frame but will not select the child frame after its creation.

buffer-predicate

The buffer-predicate function for this frame. The function other-buffer uses this predicate (from the selected frame) to decide which buffers it should consider, if the predicate is not nil. It calls the predicate with one argument, a buffer, once for each buffer; if the predicate returns a non-nil value, it considers that buffer.

buffer-list

A list of buffers that have been selected in this frame, ordered most-recently-selected first.

unsplittable

If non-nil, this frame’s window is never split automatically.
