    In your target font folder AFAIK.

      I don't think it's installed font problem.
      Also i don't know PinyinInputMethod( lang-zh_CN), TCInputMethod(lang-zh_TW) and chinese languages.
      But, there are difference between the two features provided by QtVirtualKeyboard.
      Please compare the two source codes below.
      I think the layout for zh_CN is strange.

      Qt\Qt5.8\5.8\Src\qtvirtualkeyboard\src\virtualkeyboard\content\layouts\zh_CN\main.qml

      Qt\Qt5.8\5.8\Src\qtvirtualkeyboard\src\virtualkeyboard\content\layouts\zh_TW\main.qml

        Hi,

        I have question regarding the virtual keyboard topic mentioned before and especially for the chinese one. How can I get the upper frame of the keyboard layout for the additional chinese letters.
        Is it just a word prediction with hunspell or is it an independent mechanism to show additional letters depending on the current selected one?

        I tried the virtual keyboard example with all languages. But with simplified chinese I have only normal alpha numeric letters like at the official QT link. But they can chose a chinese letter if they typed in some alpha numeric ones.

        you can see an example here (Pinyin keyboard layout, Zhuyin keyboard layout, Cangjie keyboard layout):

          I assume you are using Windows & minGW.
          Try the following procedure.

          1. Open the Command window (aka Qt 5.8 for Desktop...)
          2. Move to the plugin dir. (cd Qt\Qt5.8\5.8\Src\qtvirtualkeyboard\src/virtualkeyboard)
          3. Add the "CONFIG += lang-fi_FI" in virtualkeyboard.pro and save.
          4. Run qmake
          5. Run mingw32-make
          6. Run mingw32-make install
          7. Rebuild your exampls and run.

          again after few days when i try to do the same thing, follow the same steps through command prompt,

          1 Open the Command window (aka Qt 5.8 for Desktop...)
          2 Move to the plugin dir. (cd Qt\Qt5.8\5.8\Src\qtvirtualkeyboard\src/virtualkeyboard)
          3 Add the "CONFIG += lang-fi_FI" in virtualkeyboard.pro and save.
          4 Run qmake
          5 Run mingw32-make
          6 Run mingw32-make install
          7 Rebuild your exampls and run

          The button is not enabled for respective language. and i am using

          path : Qt\Qt5.8\5.8\Src\qtvirtualkeyboard\examples\virtualkeyboard\basic is app to run.

          path : Qt\Qt5.8\5.8\Src\qtvirtualkeyboard\src\virtualkeyboard is the plugin to which we need to change and check,

          any clue what i am doing wrong, few days back i tried it worked, now i dnt know what happened?.

          Thanks,

              This works fine for windows,

              Anyone, who knows the similar commands to run in ubuntu,

              What are the steps to compile the qt virtual keyboard and run the Qt virtual keyboard in ubuntu.

              Thanks,

                  Hi,

                  The steps are the same except that your call make rather than mingw32-make.

                  Just ensure you use the full path to your installed Qt's qmake. Otherwise you'll likely use your system provided qmake.

                    Hi,

                    I have used the path where virtual keyboard plugin is present

                    /home/user/Qt5.8.0/5.8/Src/qtvirtualkeyboard/src/virtualkeyboard/

                    then used qmake .
                    then used the command make.

                    getting the below error.

                      Except that your are building against a 5.4.0 version of Qt. Did you use the full path to the qmake from your cross-compiled Qt ?

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

                          Qt5.8.0/5.8/gcc_64/bin/qmake

                          I thought you want to build for your target device using your cross compiled Qt 5.4? Now you're building for desktop Qt 5.9. What do you want to do?

                            Hi,

                            I want to compile the virtualkeyboard for ubuntu and raspberry pi board as i did for windows,

                            In windows i was able to compile and get it,
                            here is the screenshot

                            https://postimg.org/image/xfcbfbmmp/

                            So i was trying and getting the errors as mentioned in my earlier post,

                            So asking guidance,

                            Thanks,

                              Like I already wrote: use the full path to the qmake executable matching the version of Qt you want to build the module for.

                              Also, use out of source builds since you are going to compile for several platforms, that will avoid "polluting" the source tree with build artefacts.

                                @SGaist said in Example of Virtual Keyboard showing in different languages:

                                Like I already wrote: use the full path to the qmake executable matching the version of Qt you want to build the module for.

                                Also, use out of source builds since you are going to compile for several platforms, that will avoid "polluting" the source tree with build artefacts.

                                Use the full path?.

                                can u explain this well Qt5.8 is installed in home directory i am using fullpath only.
                                /home/user/Qt5.8.0/5.8/gcc_64/bin/qmake

                                Thanks,

                                  Just to be sure, are we clear that this one will only be valid for building the module for your Qt 5.8 installation ?

                                  By the way, what version of g++ are you running on your machine ?

                                        @Pradeep-Kumar Make sure you're building from a clean state!
                                        What I mean: if you don't use out of source build then extract the source code archive again and try to build again. Better to use out of source builds as @SGaist suggested.
