QTVirtualKeyboard plugin - disabled keys are enabled if layout was switched

[AndreFiedler]

Hi,

I have a strange behaviour of the qtvirtualkeyboard plugin. You can see it in this video:

If the user switches between "&123" and "ABC" layout, everything is fine - all disabled keys are still disabled. But if the user switches between "1/2" and "2/2" layout, they are enabled again. But if you then switch again between "&123" and "ABC" they are disabled again. Thats strange.

What can be wrong? Or how can I fix this?

This is my code to disable the keys (by now I have no code to enable them again, so they must be disabled still):

    property var keyboardLayout: inputPanel.keyboard.layout
    property var specialKeysDiabled: false

    function disableSpecialKeys(parent) {
        specialKeysDiabled = true
        var obj = null
        if (typeof parent == "undefined" || !parent)
        {
            parent = inputPanel.keyboard
        }
        var children = parent.children
        for (var i = 0; i < children.length; i++) {
            obj = children[i]
            if (
                /[^a-zA-Z0-9\(\)_\s]/.test(obj.text) && 
                obj.toString().substring(0, 7) === "BaseKey"
            ) {
                obj.enabled = false
            }
            if (obj === null) {
                break
            }
            obj = disableSpecialKeys(obj)
            if (obj)
            {
                break
            } 
        }
        return obj
    }

    onKeyboardLayoutChanged: {
        if (keyboardLayout !== "") {
            if (specialKeysDiabled) {
                disableSpecialKeys()
            }
        }
    }
