sbron 2 Jun 2007: A request for a Mac style search widget (an entry widget with "curved corners" and a magnifying glass embedded as an image) from Kevin Walzer on clt triggered me to try if that could easily be achieved using Tile. I whipped up the code below that creates an entry widget looking like this:


This is the code:
 package require Tk
 package require tile

 set data {

Using Tcl/Tk 8.5b1 (on Mac OSX Tiger 10.4.10) which has Tile integrated (version 0.8.0), the "style element create" command returns an error on the -map option. According to the current tile manpages, 'element create' takes a list of images and states rather than a single image. So, changing the element create line from
 ttk::style element create Search.field image search1

to
 ttk::style element create Search.field image {search1 focus search2}

will do what the original code did (thanks to dkf for the hint!).

See also [1] for the official explanation.

The -map option to ttk::style element create has been merged into the image specification so it works like other -image options so the image value now takes a list comprising of {defaultImage ?state1 image1?} see http://www.mofeel.net/872-comp-lang-tcl/7213.aspx :
ttk::style element create Search.field image {search1 focus search2} \
     -border {22 7 14} -sticky ew
