i have a scroll window that displays a horizontally packed group.
the user appends widgets to the group at runtime. it would really be nice
if there was an option for right justifying the group in the scroll
window. this would make the last added widget automatically visible.

For this to work, Fl_Pack::draw() needs to be separated into a layout() function that recalculates all chidden, and a draw() function that only draws. You could then add your widget, call layout, and adjust the scroll group according to the Fl_Pack width.

I'll get to it eventually if you feel that this is too difficult. The function is quite a worm.

TeXJunky: this fix will require some changes in the inner core that I am not comfortable to do for 1.3.1 or 1.3.2. I am upping this to 1.4 for now. We will need to discuss this change after 1.3.2 .

thanks for taking a look at this. i posted a file that gives a minimal framework for testing the feature. actually, i have achieved almost what i need using scroll_to and w() functions. it appears that the w() functions get updated sometime later, so my effort is a bit klutzy.
