JOB 17-12-12, based on an code snippet from RS I created a small utility package for the incredible tablelist widget. Please also note that tablelist 6.0 is out which offers even more enrichments (tablelist header subcommands and more!). The embeddedWindows.tcl demo gives a glance of what's new.
With the following text2rotatedimage package you can create vertical aligned header text, which might be quite useful to decrease the overall width of a tablelist widget.
Down below is the source code of the package. It is flagged as experimental, so please feel free to place any comments or improvements.
In order to get the code running, please copy over the checked.gif and unchecked.gif images from the tablelist package.
