INNER {returnImm {Unknow state transition: LINE -> END} {}} CALL {my render_wikit {Arrow buttons} {[Keith Vetter] 2003-03-12 : after seeing some tcl code on wiki pages that tried to use the "^" and "V" as arrow symbols on buttons[http://wiki.tcl.tk/1803] , I thought I'd make available simple bitmap images of the four arrows that can be used instead. Remember, you can use [Bitmap Editor] to tailor the images to exactly how you'd like them.

[KPV] 2010-07-02 : added diagonal arrows

[RS] wonders if such arrows should not be added to [Tk]'s built-in [bitmap]s...

[RLH] I tried it. Nice little arrows, it would be nice if they could be added.

[peterc] 2010-07-09: Another avenue worth looking at is trawling through UTF tables like this [http://www.fileformat.info/info/unicode/block/geometric_shapes/list.htm] and [http://www.fileformat.info/info/unicode/block/arrows/list.htm] for a text code (eg: \u25BC). Most platforms have good support for extended UTF characters now.
