Re: Role Application issue

Hi,

We have various components in our widget area. Some of the *few* are listed
below
1. Desktop
2. File Explorer
3. Control Panel/ Settings
4. MS Office (Applications - Excel, Powerpoint, Access, word, Outlook)
5. Internet Explorer
6. Start Menu
7. Task bar
and others.
Its kind of a personal machine inside a web browser.
Office component will support everything including panes, dialog boxes,
file menu *every *feature that office supports.

We have provided role application because inside app Area we have our own
keyboard shortcut to interact with the application.

Also when page is loaded then depending on the parameters provided above
widgets are loaded. There are more then 7000 scenarios for this.

So it is not possible to actually find which will be the focused element
when page is loaded. Also sometimes inner component loses focus by calling
blur and then track key down on body for keyboard handling. So even if we
track the first focused element how can we capture the keys when focus is
moved in between to body by a inner component. Also considering the
complexity and vast code of widgets and components it is not possible to do
any change related to this in components. So looking for a common solution.

Regards
Nikhil Mittal
