Adding custom layout to qt virtual keyboard

[manny_lp]

Hi all,
I am creating a Qt Qml application which has a simple Text field and Input panel.
I am trying to override the default virtual keyboard layout, by using QT_VIRTUALKEYBOARD_LAYOUT_PATH environment variable as follows:
qputenv("QT_VIRTUALKEYBOARD_LAYOUT_PATH",":/layouts");
layouts folder contains en_GB subfolder having qml files of keyboard layout.
When I run the application I am not seeing the keyboard!!
Any solution??
(I have attached the image showing where you can see layout folder location)
