Oops, I noticed this before, but forgot to mention it. David> Then in the LaTeX-mode-hook, the following gets called David> (about which I happen to be entirely clueless). (let ((tb (cdadar (or (specifier-spec-list default-toolbar (current-buffer)) (specifier-spec-list default-toolbar 'global))))) (unless (assq preview-icon-toolbar-button tb) Use `member', not `assq'. `memq' probably works, too, but toolbars are short, the buttons are short and shallow, and this code gets called rarely (ie, approximately once per LaTeX file). I suggest not worrying about efficiency. (set-specifier default-toolbar (append tb (list preview-icon-toolbar-button)) (current-buffer)))) That should fix your doubled button problem. I don't understand why that code would get called more than once (that might be a bug in XEmacs), but it's the only hypothesis I can see a fix for offhand. David> Now there is one smaller problem: the glyph is generated David> from a PNG file with transparent colors. Displayed in the David> text, the transparent color is the text background color. David> Displayed in the toolbar, the transparent color is black David> instead of the toolbar color. Try (make-face 'toolbar-face "Compatibility toolbar face for XEmacs < 21.5. Use this face for glyphs used as button icons. Does not affect the toolbar itself (toolbars get faces in 21.5), and may not affect some types of glyphs (\"text\" glyphs seem to get the default face; XPMs and xface glyphs get the right face). Probably the only property that matters is the background color.") (set-face-background 'toolbar-face (frame-property (selected-frame) 'background-toolbar-color)) (set-glyph-face (car (aref preview-icon-toolbar-button 0)) 'toolbar-face) in the initialization of preview-latex. (This should also work on the fly if you happen to have a toolbar with the ugly PNG displayed.)
