* gtk/gtklabel.[hc]: some cleanups, fixed mnemonic_widget handling,
added PROP_MNEMONIC_WIDGET.
* gtk/gtkwindow.c (gtk_window_activate_mnemonic):
(gtk_window_remove_mnemonic):
(gtk_window_add_mnemonic): fixed assertions.
(gtk_window_activate_mnemonic): constrain modifier checks to those
permitted by gtk_accelerator_get_default_mod_mask().
got rid of gtk_window_get_default_accel_group().
* gtk/gtkwidget.c (gtk_widget_real_activate_mnemonic): handle non
activatable widgets either by focussing or a warning.
added a signal accumulator to ::activate_mnemonic which stops the
emission once a handler returned TRUE.

<!-- ##### FUNCTION gtk_window_set_policy ##### -->

<para>

Changes how a toplevel window deals with its size request and user resize
|
|
attempts. There are really only two reasonable ways to call this function:
|
|
<orderedlist>
|
|
<listitem>
|
|
<para>
|
|
<literal>gtk_window_set_policy(GTK_WINDOW(window), FALSE, TRUE, FALSE)</literal>
|
|
means that the window is user-resizable.
|
|
</para>
|
|
</listitem>
|
|
<listitem>
|
|
<para>
|
|
<literal>gtk_window_set_policy(GTK_WINDOW(window), FALSE, FALSE, TRUE)</literal>
|
|
means that the window's size is program-controlled, and should simply match
|
|
the current size request of the window's children.
|
|
</para>
|
|
</listitem>
|
|
</orderedlist>
|
|
The first policy is the default, that is, by default windows are designed to
|
|
be resized by users.
|
|
</para>
|
|
|
|
<para>
|
|
The basic ugly truth of this function is that it should be simply:
|
|
<programlisting>
|
|
void gtk_window_set_user_resizeable(GtkWidget* window, gboolean setting);
|
|
</programlisting>
|
|
So, pretend it is like that, and only use the two policies mentioned above.
|
|
GTK+ 1.4 may replace gtk_window_set_policy() with a nicer function like
|
|
gtk_window_set_user_resizeable().
|
|
</para>
|
|
|
|
<para>
|
|
If set to TRUE, the @allow_grow parameter allows the user to expand the window
|
|
beyond the size request of its child widgets. If @allow_grow is TRUE, be sure to
|
|
check that your child widgets work properly as the window is resized.
|
|
</para>
|
|
|
|
<para>
|
|
A toplevel window will always change size to ensure its child widgets receive
|
|
their requested size. This means that if you add child widgets, the toplevel
|
|
window will expand to contain them. However, normally the toplevel will not
|
|
shrink to fit the size request of its children if it's too large; the
|
|
@auto_shrink parameter causes the window to shrink when child widgets have too
|
|
much space. @auto_shrink is normally used with the second of the two window
|
|
policies mentioned above. That is, set @auto_shrink to TRUE if you want the
|
|
window to have a fixed, always-optimal size determined by your program.
|
|
</para>
|
|
|
|
<para>
|
|
Note that @auto_shrink doesn't do anything if @allow_shrink and @allow_grow are
|
|
both set to FALSE.
|
|
</para>
|
|
|
|
<para>
|
|
Neither of the two suggested window policies set the @allow_shrink paramter to
|
|
TRUE. If @allow_shrink is TRUE, the user can shrink the window so that its
|
|
children do not receive their full size request; this is basically a bad thing,
|
|
because most widgets will look wrong if this happens. Furthermore GTK+ has a
|
|
tendency to re-expand the window if size is recalculated for any reason. The
|
|
upshot is that @allow_shrink should always be set to FALSE.
|
|
</para>
|
|
|
|
<para>
|
|
Sometimes when you think you want to use @allow_shrink, the real problem is that
|
|
some specific child widget is requesting too much space, so the user can't
|
|
shrink the window sufficiently. Perhaps you are calling gtk_widget_set_usize()
|
|
on a child widget, and forcing its size request to be too large. Instead of
|
|
setting the child's usize, consider using gtk_window_set_default_size() so that
|
|
the child gets a larger allocation than it requests.

it's larger
