how do I make an XView button look pressed? call panel_begin_preview() and panel_cancel_preview(); these are documented in -- er -- the XView 3 source...

Parent document is top of "OPEN LOOK GUI FAQ 03/04: the XView Toolkit"
Previous document is "How do I keep a pop-up window displayed after a button is pressed? In the button callback, do xv_set(button, PANEL_NOTIFY_STATUS, XV_ERROR, NULL); This will keep the window visible. You might also need to investigate the MENU_NOTIFY_STATUS attribute."
Next document is "OpenWindows 3 imake doesn't work properly Here is Greg Earle's patch, to be applied in $OPENWINHOME; note that you should edit lib/config/ afterwards to get OSName and OSMinorVersion right (MinorVersion is 1 in SunOS 4.1.2, for example). I have edited the patch a little, so any bugs are mine [] :-)"
