GNOME Bugzilla – Bug 350806
Shift-Tab doesn't work with Quartz back end
Last modified: 2006-09-06 17:30:17 UTC
I can change the focus to the next control by pressing Tab, but not to the previous one by pressing Shift-Tab. This is easy to demonstrate with the Button Boxes and Pickers demos. Other information: I'm using the following libraries on OS X 10.4.7 with the Quartz back end: $ pkg-config --modversion gtk+-2.0 atk pango cairo 2.10.1 1.12.1 1.14.0 1.2.2
I can also see this. I have looked briefly into why this is but haven't found anything so far.
GTK+ expects a keysym of GDK_ISO_Left_Tab for Shift-Tab. If you look, you'll find code in the Win32 backend, and in the non-XKB code path for the X backend to munge the keysym in that case.
Ah thanks. Fixed in CVS HEAD.
