Android, character counter for TextEdit

[blackdog]

I'm trying to write a character counter for a TextEdit field.
I have tryed numerous ways that work fine on the desktop, but on Android it fails when the space key is pressed and then only works when space key is pressed.
What am I missing?

I am not sure I understand.
The length of the text does not increase if spaces are added on Android?

No, here is some code that shows the problem:

import QtQuick 2.0
import QtQuick.Controls 1.3
Item {
    Rectangle { 
        id: textin
        anchors.top: parent.top
        anchors.topMargin: parent.height / 10
        width: parent.width * 0.8
        height: parent.height / 3
        anchors.horizontalCenter: parent.horizontalCenter
        border.color: "#000000"
        TextEdit { 
            id: ptext
            anchors.fill: parent
            clip: true
            textMargin : 10
            wrapMode : Text.WordWrap
            text: "test"
            onTextChanged: {
                textcount.text = ptext.text.length
                console.log(text, ptext.text.length)
            }
        }
        Text { 
            id: textcount
            anchors.bottom: textin.bottom
            anchors.right: textin.right
            width: parent.width * 0.2
            height: parent.height * 0.2
        }
    }
}

import QtQuick 2.0
import QtQuick.Controls 1.3
Item {
    Rectangle { 
        id: textin
        anchors.top: parent.top
        anchors.topMargin: parent.height / 10
        width: parent.width * 0.8
        height: parent.height / 3
        anchors.horizontalCenter: parent.horizontalCenter
        border.color: "#000000"
        TextEdit { 
            id: ptext
            anchors.fill: parent
            clip: true
            textMargin : 10
            wrapMode : Text.WordWrap
            text: "test"
            onTextChanged: {
                textcount.text = ptext.text.length
                console.log(text, ptext.text.length)
            }
        }
        Text { 
            id: textcount
            anchors.bottom: textin.bottom
            anchors.right: textin.right
            width: parent.width * 0.2
            height: parent.height * 0.2
        }
    }
}

To copy to clipboard, switch view to plain text mode 

qrc:/debug.qml:19 (onTextChanged): qml: test 4
qrc:/debug.qml:19 (onTextChanged): qml: testa 5
qrc:/debug.qml:19 (onTextChanged): qml: testab 6

qrc:/debug.qml:19 (onTextChanged): qml: testabc 8
qrc:/debug.qml:19 (onTextChanged): qml: testabc 8
qrc:/debug.qml:19 (onTextChanged): qml: testabc 8

So after the first space the text doesn't actually change until the next space?

I wonder why that triggers onTextChanged at all.

Maybe the input method or virtual keyboard on Android holds modifications back, e.g. for auto completion, etc.?

Yes thats the problem.
I don't use auto-completion and the characters show in the TextEdit field.
Any idea how to write a text lenght counter in QML that works on Android?

Cheers,
