@ -275,3 +275,19 @@ Text/Edit widget:
- "changed" emitted when doing deletes on empty Text widget.
- Delete IC in editable->unrealize, not editable->finalize?
Calendar Widget:
- The widget should be nicely resizeable vertical to.
- CALENDAR_MARGIN should be removed, uses INNER_BORDER and
style->class->[xy]thickness insted.
- Flag to choose between using standard three letter abbreviated
weekday name or just the first character from it. It looks like
that is what most other calendar-widgets do.
- Arrows should resize with the header-font.
- The keyboard support has to be finished.
