[g-a-devel]GKB Applet - Accessibility

["Parag Kabra" <parag kabra wipro com>]

Hi All,
    I have done a study of GKB Applet from an accessibility perspective.
Your comments are invited regarding the same.

 Applet Name : GKB Applet
 Description : This is an "International Keyboard Switcher" applet which
provides switching between keymaps of different languages.
Custom Widgets :
GnomeMessageBox, GnomeAbout, GnomeHRef, GnomeIconEntry. -- All these custom
widgets are made accessible through libgnomeui.
ATK interfaces inherited and provided:
       Accessible Name  -- Implementation inherited from GailWidget
       Accessible Description --  Implementation inherited from GailWidget
(ToolTip)
       Accessible Role  -- Implementation inherited from GailWidget
       AtkAction Interface  -- Accelerator support inherited from
GailWidget.
       AtkComponent Interface -- Implementation inherited from GailWidget.
Clarification Required
   AtkImage Interface -- Accessible Implementation Provided by GailImage.
This is for the country's flag that is displayed in the GKB applet. But this
is not displayed in Ferret. The reason that I can think of is that GtkImage
displaying the flag  is finally contained in a GtkEventBox which is not a UI
element.
ATK interfaces required :
     AtkAction Interface  --  Atk Implementation needs to be provided for
handling the "button_press_event" emitted by the GtkEventBox that serves as
a container for the country's flag and label. When the GKB applet is clicked
( pressed ) the next keymap and label in the list  is displayed.
         But there still is a possibility that even after implementation it
may not be displayed in Ferret for the same reasons that AtkImage is not
being shown?
         A hot key can be grabbed and use for switching between keymaps
thereby providing accessibility to switching but this is done only after
setting in
"GKB Properties". Hence I think an AtkAction interface is required.
    AtkRelation Interface -- In GKB Properties - Options - Atk
Implementation needs to be provided for relating the "Appearance" and
"Applet size" labels to their corresponding menus.

Regards,
Parag.
