Grabbing on a non-toplevel might not do what we want it to do, since it
will go on the focused widget, not the grabbed widget. Since we don't
focus the widget before clicking on it, that means that putting the
focus somewhere else and then clicking on the accelerator editor will
freeze the app. Additionally, since it's a global system grab that can't
be exited except by a key press that we won't ever get, it effectively
locks up your system as well unless you know how to break the grab or
kill the app. Ouch.
Since doing a device grab on a non-toplevel is generally considered a
bad idea, just don't do it. Use a GtkInvisible and take a grab on that
instead.
I'm adding a bunch of fixes for gcc complaining about
-Wmissing-declarations.
This set of patches makes private classes in gtk/*.c that use
G_DEFINE_TYPE() safe by adding definitions for the get_type() function
that can't be made static.
We want to use Alt+Print for screenshot keybindings, so we have to avoid
translating it into SysRq, since that's what the keymap would dictate.
After talking with Owen, it sounds like doing this generically would be
a lot of work and quite hairy code, so hardcoding this should be OK.

Since GtkCellRendererText moved to WFH requests, our get_size
implementation is ignored. We should override get_preferred_width
instead. This fixes the accel renderer being clipped to a wrong size
when trying to edit its shortcut.
Calling gdk_keymap_add_virtual_modifiers causes _all_ virtual
modifiers to be added, which causes problem when they are co-located
on the same real modifier (as Super and Hyper often are). Effectively,
this made it impossible to enter key combinations involving Super,
since they all turn into Super+Hyper.
If the keyboard group shifting modifier is *also* a normal
accelerator modifier, we need to special case it when calling
gdk_keymap_translate_keyboard_state(), so we get the right
key symbol for accelerators (for example we want Option-O,
not Option-Ø displayed in menu items). This patch should only
affect quartz where the Alt key both shifts the group and can
be used as accel modifier, and not X11 or Win32 where AltGr
is not used for accelerators.
- fix quartz' gdk_keymap_translate_keyboard_state() to return
the right consumed_modifiers
- add _gtk_translate_keyboard_accel_state() which does the
special casing
- use it everywhere instead of gdk_keymap_translate_keyboard_state()
It doesn't make sense to keep them separate as GtkSizeRequest requires a
GtkWidget and GtkWidget implements GtkSizeRequest, so you can never have
one without the other.
It also makes the code a lot easier because no casts are required when
calling functions.
Also, the names would translate to gtk_widget_get_width() and people
agreed that this would be a too generic name, so a "preferred" was added
to the names.
So this patch moves the functions:
gtk_size_request_get_request_mode() => gtk_widget_get_request_mode()
gtk_size_request_get_width() => gtk_widget_get_preferred_width()
gtk_size_request_get_height() => gtk_widget_get_preferred_height()
gtk_size_request_get_size() => gtk_widget_get_preferred_size()
gtk_size_request_get_width_for_height() =>
gtk_widget_get_preferred_width_for_height()
gtk_size_request_get_height_for_width() =>
gtk_widget_get_preferred_height_for_width()
... and moves the corresponding vfuncs to the GtkWidgetClass.
The patch also renames the implementations of the vfuncs in widgets to
include the word "preferrred".
The keysyms create a lot of potential namespace conflicts for
C, and are especially problematic for introspection, where we take
constants into the namespace, so GDK_Display conflicts with GdkDisplay.
For C application compatiblity, add gdkkeysyms-compat.h which uses
the old names.
Just one user in GTK+ continues to use gdkkeysyms-compat.h, which is
the gtkimcontextsimple.c, since porting that requires porting more
custom Perl code.
GtkCellRendererAccel also needs to acquire the GTK+ grab in addition to
a GDK keyboard grab. With the GDK keyboard grab, KeyPress and
KeyRelease events are delivered as usual, although we only want to
receive them for our grab widget.

* gtk/gtkcellrendereraccel.c (gtk_cell_renderer_accel_get_property):
implement getter for keycode property. (#476665, patch by
Christian Persch).
svn path=/trunk/; revision=18817
2006-11-16 Michael Natterer <mitch@imendio.com>
Add new infrastructure for notifications of failed keyboard
navigation and navigation with restricted set of keys.
The patch handles configurable beeping, navigating the GUI with
cursor keys only (as in phone environments), and configurable
wrap-around. Fixes bugs #322640, #70986, #318827, #334726, #334742
and #309291.
* gtk/gtksettings.c: added properties gtk-keynav-cursor-only,
gtk-keynav-wrap-around and gtk-error-bell.
* gtk/gtkwidget.[ch]: added new signal "keynav-failed" and public
API to emit it. Added New function gtk_widget_error_bell() which
looks at the gtk-error-bell setting and calls gdk_window_beep()
accordingly.
* gtk/gtk.symbols: add the new widget symbols.
* gtk/gtkcellrendereraccel.c
* gtk/gtkimcontextsimple.c
* gtk/gtkmenu.c
* gtk/gtknotebook.c: use gtk_widget_error_bell() or look at the
gtk-error-bell setting instead of calling gdk_display_beep()
unconditionally.
* gtk/gtkcombobox.c
* gtk/gtkentry.c
* gtk/gtkiconview.c
* gtk/gtklabel.c
* gtk/gtkmenushell.c
* gtk/gtkspinbutton.c
* gtk/gtktextview.c
* gtk/gtktreeview.c: call gtk_widget_error_bell() on failed keynav.
* gtk/gtkentry.c
* gtk/gtklabel.c
* gtk/gtkrange.c
* gtk/gtktextview.c: consult gtk_widget_keynav_failed() on failed
cursor navigation and leave the widget if it returns FALSE.
* gtk/gtkmenushell.c
* gtk/gtknotebook.c: only wrap around if gtk-keynav-wrap-around
is TRUE.
* gtk/gtkradiobutton.c: ask gtk_widget_keynav_failed() to decide
whether to to wrap-around, and don't select active items on cursor
navigation if gtk-keynav-cursor-only is TRUE. Should look at
gtk-keynav-wrap-around too, will look into that.
