Example of Virtual Keyboard showing in different languages

[jsulm]

@Pradeep-Kumar said in Example of Virtual Keyboard showing in different languages:

.obj/platforminputcontext.o: error adding symbols: File in wrong format

you should do it from a clean state - looks like you have binaries built with the old compiler.

[Pradeep Kumar]

Yes @jsulm i got that point made a clean then built it i got the virtual keyboard, but i am not getting for different languages, tats y i posted in earlier post.

Thanks,

AFAICS you are setting only one language when building the module. You should list all the languages you want to support.

[Pradeep Kumar]

nope still the same, i provided 4 languages in .pro file,

still the same issue.

when i run make install

-Inspiron-3558:~/Qt5.8.0/5.8/Src/qtvirtualkeyboard/src/virtualkeyboard$ make install
install -m 755 -p ../../plugins/platforminputcontexts/libqtvirtualkeyboardplugin.so /home/user/Qt5.8.0/5.8/gcc_64/plugins/platforminputcontexts/libqtvirtualkeyboardplugin.so
strip --strip-unneeded /home/dheerendra/Qt5.8.0/5.8/gcc_64/plugins/platforminputcontexts/libqtvirtualkeyboardplugin.so
install -m 644 -p /home/user/Qt5.8.0/5.8/Src/qtvirtualkeyboard/lib/cmake/Qt5Gui/Qt5Gui_QVirtualKeyboardPlugin.cmake /home/dheerendra/Qt5.8.0/5.8/gcc_64/lib/cmake/Qt5Gui/

after this i run sample program.

Thanks,

The Qt open source package contains the qtvirtualkeyboard component.
I can build it without anu problem but I can't add the flag lang-all.
Insert CONFIG += lang-all in .pro file has no effect.

Hello,

now i am facing one more issue, when i try to compile the program using Qt creator,
getting the below mentioned errors,

home/user/Qt5.8.0/5.8/gcc_64/mkspecs/features/qt_plugin.prf:52: Cannot write file /mkspecs/modules-inst/qt_plugin_qtvirtualkeyboardplugin.pri: Cannot create parent directory
17:58:18: The process "/home/user/Qt5.8.0/5.8/gcc_64/bin/qmake" exited with code 3.
Error while building/deploying project virtualkeyboard (kit: Desktop Qt 5.8.0 GCC 64bit)
The kit Desktop Qt 5.8.0 GCC 64bit has configuration issues which might be the root cause for this problem.
When executing step "qmake".

But the kit is configured and rest of the programs are running, only the virtualkeyboard program is giving me this error...

Guidance is required,

Thanks,

@Pradeep-Kumar said in Example of Virtual Keyboard showing in different languages:

Cannot write file /mkspecs/modules-inst/qt_plugin_qtvirtualkeyboardplugin.pri

Are you really trying to write to /mkspects ? This would be a subdirectory of the root directory where a normal user has no write access. Does this directory even exist?

[Pradeep Kumar]

Nope i dnt know regarding that as i was trying to compile the qtvirtualkeyboard program in ubuntu, i am getting the error, but i didnt find the compiling error in windows, strange.

is their any other configuration to be done.

Thanks,

Can you show your .pro file ?

Again, did you start using out of source builds ?
Between two tries, did you nuke the build folder ? If so, how did you nuke it ?

Just added CONFIG += lang-ar_AR lang-fr_FR , to get the keyboard in arabic and french,
and i didnt change any other line,
its nt compiling in Qt creator,

I am not using out of source, and i deleted .pro.user file,deleted build folder then tries to compile, still no change, its not compiling.

Thanks,

[michaelL]

@Pradeep-Kumar dont use that project but the qtvirtualkeyboard.pro project that is above that directory and inside the .pro looks like this:

OTHER_FILES += README.md

load(qt_parts)
QT += core
CONFIG+= lang-all

add one more step "make" in build and put in arguments "install"

For me the project location is "Qt5.7.1/5.7/Src/qtvirtualkeyboard/qtvirtualkeyboard.pro"
What you are building is located on "Qt5.7.1/5.7/Src/qtvirtualkeyboard/src/virtualkeyboard/virtualkeyboard.pro"

I am able to see all languages on my linux desktop.

I also compiled with same QTCreator on desktop using qmake for my embedded linux and could see all languages except chinese/korea/japan/tawain. I keep getting "japaneseInputMethos is not a type" and so on.
Could anyone get those to work? On my PC they work but not on embedded.
I followed this section http://doc.qt.io/qt-5/qtvirtualkeyboard-deployment-guide.html and deploy the plugins to my embedded linux but i get all languages except those. Is there any other files i have to deploy for Japan/Korea/Chinese/Tawain languages?
Any idea?

[Pradeep Kumar]

Hi,

@michaelL

so what is the difference between the qtvirtualkeyboard in the path

Qt5.7.0/5.7/Src/qtvirtualkeyboard/src/virtualkeyboard/virtualkeyboard.pro

and

in Qt5.7.0/5.7/Src/qtvirtualkeyboard/qtvirtualkeyboard.pro,

And i am not getting in respective languages, from the path
Qt5.7.0/5.7/Src/qtvirtualkeyboard/qtvirtualkeyboard.pro

Are u getting?

Thanks,

[michaelL]

@Pradeep-Kumar the Qt5.7.0/5.7/Src/qtvirtualkeyboard/qtvirtualkeyboard.pro is the main project for all of the inside projects. You have to build it so that all files/languages/layout and so on are compiled too. I think the projects inside have dependencies of the others.
I am getting all languages on my PC running Qt5.7.1
If you use QT Creator to make the project you have to add a "Build step" in "build settings" under "build setps"
The step you add is "make" and type in arguments "install".
So qt creator will do qmake->make->make install
If it does it with no error you can open the basic example project and you will get all languages.
