[Qt-interest] how I can know the widget is editable?

[Malyushytsky, Alex]

First, I would appreciate if you reply to the mailing list only.

As I already mentioned I don’t see a way to implement general approach.
If I were you I would implement recognizion  as much standard widgets as I could.
Would certainly provide easy and fast manual access to the onscreen keyboard.
In addition you can make yor keyboard smart. For example it can remember list of the widgets user was requesting it for and update database of such widgets.

Regards,
  Alex

Thank you for your reply, I am working on a onscreen keyboard. I want the
keyboard can show itself automatically. now I developed a plugin using
 QInputContext class , because I found this class has a virtual function called
setFocusWidget it can get a QWidget pointer pointing to current focused widget.
but the focused widget may be not an editable widget, so I think I should know that.
If the widget is an editable widget it can call a DBus method to show the virtual key
board. Do you have other idea to do this?
BR,
Edward.
