If you have the 'devx' SFS file loaded, you will find code examples at /usr/share/doc/gtkdialog3, which are invaluable. However, Gtkdialog has capabilities that are not documented or hardly so.
Whatever aids we can get are most welcome. I did not know all the capabilities of the text markup mode, but forum member vovchik found a "Gtkdialog text markup editor" GUI application, in French that he has translated and made available for us:
This is just a small script, so I have put it into the Woof rootfs-skeleton, as /usr/sbin/markup, and created a menu entry, in the "Utility" category.

Since zigbert seems to be the Gtkdialog man around puppy I'll run it past him... don't know if he reads this blog. Thanks Barry and vovchik.
