Add a utility function to translate coordinates relative to one widget's
Tue Oct 16 15:50:03 2001 Owen Taylor <email@example.com> * gtk/gtkwidget.c (gtk_widget_translate_coordinates): Add a utility function to translate coordinates relative to one widget's allocation to coordinates relative to another widget's allocation. * gtk/gtkradiobutton.c: Add a special ->focus() implementation that: - only accepts external focus if there is no active member of the group or the button is active. - makes arrow keys move the active button as well as the focus - make tab tab out directly. This makes a radio button group act as a single focus location. (#53577). * gtk/gtkcontainer.c (gtk_container_focus): Remove prefiltering - it was only a small optimization that didn't matter and made things more complicated. * gtk/gtkcontainer.c (gtk_container_focus_tab): Get rid of custom sorter for FOCUS_TAB as we did for the other focus directions, sort by center of widgets, not upper-left corner. (Shouldn't matter in general.) * gtk/gtkcontainer.c: Restructure code to remove duplicate code from the different types of focusing: encapsulate sorting the widgets for the focus direction into one routine (gtk_container_focus_sort()) and then share the work of moving the focus between the different focus directions. * gtk/gtkcontainer.c: Fix bug where arrow navigation might not work correctly with focus chains containing non-immediate children. Sorting was being done using allocation coordinates for each widget in the focus chain, and if there were intermediate window-widgets, these allocations would not be in the same coordinate system.
