GtkWidget::add_accelerator
void add_accelerator(string accel_signal,
GtkAccelGroup
accel_group
, int accel_key, GdkModifierType accel_mods,
GtkAccelFlags
accel_flags
);
add_accelerator() defines and
adds a keyboard accelerator to the calling widget, usually a
GtkMenuItem.
The first parameter is the name of the signal that you want the widget
to emit when the key is pressed. Generally this will probably be
"activate".
The second parameter is the GtkAccelGroup that
this GtkAccelEntry will belong to when it has been
created. This will generally be an accelerator group that has been
newly created and added to the toplevel window.
Thirdly there is the accel_key parameter. This
can be pulled from the GtkAccelLabel using the
parse_uline() method if you have
an underscore under the appropriate letter, or alternatively you could
use the key symbols which have been hard-coded into PHP-GTK. Usually
these would be in the format GDK_KEY__a - always in
lower case, because the accelerator functions return lower case key
values.
The full list of PHP-GTK key symbol hard codings is available in
the source code in the file ext/gtk+/php_gdk.c.
The fourth and fifth parameters are
GdkModifierType and
GtkAccelFlags respectively. In both cases,
passing 0 is accepted as a null field.
There is no limit on the number of accelerator keys that can be
associated with a widget.
