How is the Qt virtual keyboard initialized and how do I use it?

Circuits

I am taking a look at the basic example for the Qt virtual keyboard. I can't seem to find any initialization for the keyboard or any place in the QML where it is being called. For instance, the only thing that happens in the QML when a user clicks the input box is that variable called focus is set too true:

... MouseArea  {
            id: content
            width: flickable.width
            height: textEditors.height + 24

            onClicked: focus = true

            Column {...

does setting focus = true start up the keyboard and if so, how?

This is described in-depth in the documentation. In short & simplified: Qt has code which handles input (mouse, keyboard etc.) abstracted into platform plugin. QtVK plugs into that - so from the point of view of your application (and yourself) QtVK is treated 100% the same as if it was a real, physical keyboard.

@sierdzio Perhaps I wasn't clear about what I am asking. In QMl events usually have some kind of trigger, right? For instance, a push button will have an onClicked function. What function, in the QML code I posted, is causing the keyboard to become visible to the user? I think perhaps you thought I was asking more broadly about how the keyboard works, in reality, I just want to know how to hook it up, say for instance, to a button press:

PushButton
         {
            text: "hello world"
            id: genericPushButton
            enabled: true
            onClicked: //What do I put here to enable the keyboard
                       //when a user clicks the push button?
         }

or perhaps a Text Field or something of that nature.

onClicked: //What do I put here to enable the keyboard
//when a user clicks the push button?

Qt.inputMethod.show()

@sierdzio This works, however; now I am left wondering how I specify the input method? For instance, activating the keyboard on a button press brings up the keyboard but it reports that:

input method is not set

when I press the button. How might I set that input method? I realize one way of doing it is by using TextInput{} or something along those lines instead of using a button. However, could I for instance alter the text property of the button itself with the keyboard?
