How to enable Virtual Keyboard Languages

? Offline

The documentation (http://doc.qt.io/qt-5/qml-qtquick-virtualkeyboard-settings-virtualkeyboardsettings.html#locale-prop) says:

locale : string
(...)
If the locale setting is incorrect, or it is not in the list of supported locales, it is ignored and the default setting is used instead.

A locale is supported if it is included in the list of availableLocales.

And in http://doc.qt.io/qt-5/qml-qtquick-virtualkeyboard-settings-virtualkeyboardsettings.html#availableLocales-prop it says:

availableLocales : list<string>
(...)
This list is read-only and depends on the build-time configuration of the virtual keyboard.

So I'd conclude that you have to rebuild VirtualKeyboard with different configuration.

I build qt 5.8 on raspberry like:

./configure -v -opengl es2 -qt-freetype -device linux-rasp-pi-g''+ -device-option CROSS_COMPILE=/usr/bin/ -optimized-qmake -reduce-exports -release -qt-pcre -qt-libpng -make libs -prefix /usr/local/qt5

How can I rebuild only virtualkeyboard module?
Can I do the same on windows?

Thanks

Hi,

You don't need to rebuild the whole Qt.
Get the module sources and then use the classic qmake/make/make install.

Take the time to checkout if there's any option you can passe to get more locale supported.

I have tried to compile the module. Then I compiled the whole Qt and still cannot get it working

SGaist

What configuration did you give when compiling the module ?

Angel Popov

@SGaist

I just copy the source from git repository.

qmake qtvirtualkeyboard.pro
make
make install

SGaist

Try with qmake "CONFIG+=lang-all".

@SGaist

Thank you! It works!

Any idea?

Hi,

You are trying to build the module that is provided with Qt 5.7.1 with the Qt version installed by your distribution which is 5.3.2. Use the full path to your 5.7.1 qmake when building the module.

I worked for me now too.
I did it in Qt Creator. Open the project and:
-In "Build Step" qmake, add in additional arguments: CONFIG+=lang-all
-Add Build Step "make" with argumant "install"
