Hello everyone,

I'm using Android 4.4.3 on a nexus 5, with Qt 5.3.0, GCC 4.8. I've 
noticed that the reported height of the virtual keyboard seems to be 
always 0.
For instance, in the following example...

import QtQuick 2.2
import QtQuick.Controls 1.1
import QtQuick.Layouts 1.1

ApplicationWindow {
     visible: true
     title: qsTr("softkeyboard test")
         flickableDirection: Flickable.VerticalFlick
         anchors.fill: parent
         contentHeight: my_contents.height
             id: my_contents
             spacing: 200
                 model: 20
                     text: "editme #"+index
     Component.onCompleted: {
     function showKeyboardStats(){
         console.log("virtual keyboard stats: visible: "+ 
Qt.inputMethod.visible+", height: 

When I run this example, I can see the following message on the log 
output, when I expand the virtual keyboard:
D/Qt      (23256): qrc:///main.qml:27 (showKeyboardStats): qml: virtual 
keyboard stats: visible: true, height: 0

... and this message when I collapse it:
D/Qt      (23256): qrc:///main.qml:27 (showKeyboardStats): qml: virtual 
keyboard stats: visible: false, height: 0

As you can see, the height of the visual keyboard is always 0, as 
reported by Qt.inputMethod.keyboardRectangle.height
Any help would be greatly appreciated.


PS: Some context of of why I care about this:
I've noticed that in QML apps on Android, the user isn't able to scroll 
all the way down the app when the virtual keyboard is expanded. In the 
example above, if I select, say "editme #2", I can only scroll to see 
"editme #16", but not the last element ("editme #19"). I thought that a 
quick fix could be to add a blank Item at the bottom and set its height 
to the height of the virtual keyboard, but this supposes that I can find 
the height of the virtual keyboard... Of course, if there's another way 
to solve this issue, I'm interested.
