How to use Qt Virtualkeyboard in my QML program?

MAthias_Va

but still I hope if any one can help !

may be a stupid question, but did you look at the docs yet?!
Also you should tell what you've done so far or what happens in your application. Otherwise i can only tell what you could also look up in the docs.

Yes @raven-worx I went through this document several times, but it is pretty tough to apply for me as a beginner,

What I could do from the doc; I was able just to run the built in Qt example!

What I need to do: I need a numeric Keypad pops up when the user try to enter text!

But I understand I need to build the Keyboard in my application, I can see the Build Instructions , but I don't know where to write it and so on!

k here is a quick overview:

no need to compile anything (unless you know why). The QtVirtualKeyboard module can be downloaded from the installer
add qputenv("QT_IM_MODULE", QByteArray("qtvirtualkeyboard")); at the very beginning of your main()
Place a InputPanel QML element where you want the keyboard to appear
In QML use a TextField, TextInput, etc. element and set it's inputMethodHints property to Qt.ImhDigitsOnly

Woow this is so easy, Once I added line 2 in the very beginning of main, I can see the Keyboard, but the weird thing is it launched in my program on start up-without calling it-, and transparent as you see in the picture below;

I see I should add

disable-desktop|android-embedded|!isEmpty(CROSS_COMPILE)|qnx {
   DEFINES += MAIN_QML=\\\"basic-b2qt.qml\\\"
} else {
   DEFINES += MAIN_QML=\\\"Basic.qml\\\"
}

in my .pro file! should it be at the end of page! is it matter here! I need it for raspberry, should I delete (disable-desktop) or keep it!

@raven-worx , finally I get it, I forget to do step 3
