2000-02-07 Kelly Lynn Martin <kelly@poverty.bloomington.in.us> * app/interface.c: restructured toolbox to use a single gtk_hwrap_box with the added "forced break" functionality to make the selector boxes not run in with the rest of the tool buttons. The toolbox should now not cut things off, although if the user selects a really small toolbox the buttons or selectors may be, um, difficult to use... * app/gtkwrapbox.h: * app/gtkwrapbox.c: * app/gtkvwrapbox.c (reverse_list_col_children): * app/gtkhwrapbox.c (reverse_list_row_children): support for "forced break" functionality needed for toolbox -- will forward patches to Tim Janik as well
