Hey, I had no clue which list to post this to. I made a quick and dirty alternative to GtkCalendar that due to screen area usage fits more nicely into a program I'm working on (I'm porting a console program to GTK). I decided to post the widget to this list just to see what kind of response it gets. I may be writing more widgets and would like to keep them consistent with the GTK style. I don't know if I should refrain from using gtk_* as functions and names. I wouldn't want to interfere with potential future widgets. One more thing, is there currently a listing of third party widgets or possibly a place to download third party widgets? If not, I am willing to compile a list and pointers to websites of third party widgets if people e-mail me the site of the widget and what license the widgets are under. I'm attaching this as 3 files because gmail for some reason is not letting me send over tar.gz files. sorry -- Irtza Sharif
