Refreshing the Screen ===================== The function `redraw-frame' redisplays the entire contents of a given frame. See Frames. - Function: redraw-frame frame This function clears and redisplays frame FRAME. Even more powerful is `redraw-display': - Command: redraw-display &optional device This function redraws all frames on DEVICE marked as having their image garbled. DEVICE defaults to the selected device. If DEVICE is `t', all devices will have their frames checked. Processing user input takes absolute priority over redisplay. If you call these functions when input is available, they do nothing immediately, but a full redisplay does happen eventually--after all the input has been processed. Normally, suspending and resuming XEmacs also refreshes the screen. Some terminal emulators record separate contents for display-oriented programs such as XEmacs and for ordinary sequential display. If you are using such a terminal, you might want to inhibit the redisplay on resumption. See Suspending XEmacs. - Variable: no-redraw-on-reenter This variable controls whether XEmacs redraws the entire screen after it has been suspended and resumed. Non-`nil' means yes, `nil' means no. The above functions do not actually cause the display to be updated; rather, they clear out the internal display records that XEmacs maintains, so that the next time the display is updated it will be redrawn from scratch. Normally this occurs the next time that `next-event' or `sit-for' is called; however, a display update will not occur if there is input pending. See Command Loop. - Function: force-cursor-redisplay This function causes an immediate update of the cursor on the selected frame. (This function does not exist in FSF Emacs.)
