Virtual keyboard on Xapps using Qt4 don't work

@luis which apps are you seeing issues with?
I tried qtcreator and calibre and both worked with the osk

Hi..I tried Psi, Dianara ...The rest, all native apps are GTK and I've
installed Thunderbird and Pidgin and no problem.

Hi...Vlc with the same problem, virtual keyboard isn't working.

Confirmed with VLC
This seems to be restricted to Qt4 apps as none of them work and all the qt5 ones I tried do

Apps not using Qt5 or GTK+3 (and a handful of other toolkits) are unlikely to work with the OSK. The fundamental assumption in most X11 applications is that there is a physical keyboard attached to the system.

In order to support redirecting OSK input through the Linux kernel uinput system for full support, we would either need to completely rewrite Maliit and considerable portions of the Unity 8 input stack or choose an alternative OSK for Desktop Applications. In either case we would lose the ability to position the keyboard on the screen appropriately for the content.

I would suggest the simplest solution is to stuck with the original restriction which was that full desktop application support will require a physical keyboard and your experience will be reduced without meeting that requirement.
