1 The SXEmacs Frame


In many environments, such as a tty terminal, an SXEmacs frame literally takes up the whole screen. If you are running SXEmacs in a multi-window system like the X Window System, the SXEmacs frame takes up one X window. See SXEmacs under X, for more information.


No matter what environment you are running in, SXEmacs allows you to look at several buffers at the same time by having several windows be part of the frame. Often, the whole frame is taken up by just one window, but you can split the frame into two or more subwindows. If you are running SXEmacs under the X window system, that means you can have several SXEmacs windows inside the X window that contains the SXEmacs frame. You can even have multiple frames in different X windows, each with their own set of subwindows.

Each SXEmacs frame displays a variety of information:

You can subdivide the SXEmacs frame into multiple text windows, and use each window for a different file (see Windows). Multiple SXEmacs windows are tiled vertically on the SXEmacs frame. The upper SXEmacs window is separated from the lower window by its mode line.

When there are multiple, tiled SXEmacs windows on a single SXEmacs frame, the SXEmacs window receiving input from the keyboard has the keyboard focus and is called the selected window. The selected window contains the cursor, which indicates the insertion point. If you are working in an environment that permits multiple SXEmacs frames, and you move the focus from one SXEmacs frame into another, the selected window is the one that was last selected in that frame.

The same text can be displayed simultaneously in several SXEmacs windows, which can be in different SXEmacs frames. If you alter the text in an SXEmacs buffer by editing it in one SXEmacs window, the changes are visible in all SXEmacs windows containing that buffer.
