Discussion about developing an onscreen keyboard in Qt

[wysota]

Qt uses X11 so it doesn't need any support for non-X11 environments. Qtopia doesn't use X11 (or at least it doesn't have to), it uses its own integrated pseudo-window manager, so the window manager might have support for transfering events into another application. At worst you can probably use QCopChannel for that although I guess the other application would need to be aware of it (like with D-Bus).

ya, Qtopia uses its own window manager. I am not sure whether to use Qtopia or Qt/Embedded. Does Qt/Embedded has its own window manager too?

Basically the on-screen keyboard will be used for opera browser, so when user clicks buttons on the on-screen keyboard it should be propagated to opera.

Qt/Embedded and Qtopia are/used to be the same thing. Now we have Qt Embedded which is a "middle" layer for embedded systems (including the wm) and Qt Extended (which used to be called Qtopia Core, I think) which is an "upper" layer for embedded systems that contains things like GSM support, text messages, contacts, etc.

Doesn't Opera need X11 (and Qt3 by the way)?

thanks for the info regarding Qtopia and Qt/Embedded.
Opera does need Qt3 and we have Qt3 libraries on the embedded hardware so opera runs fine on it. I am not sure if Opera needs X11, it shouldn't since our older hardware doesn't have X11.

I still don't know what to do for transfering events to other applications.
