how to regenerate an UI stochastically in QML using a Button on the interface? - qt

Question

I am working on the following QML framework for music apps user-interface prototyping:
https://github.com/tiagmoraismorgado/TMM_QML_UI_UX_FRAMEWORK_WIP in the file instiationTest, i need to add a type Button1_1 and then use it to regenerate the whole gui based on combostochasticselector.
i know i have to instantiate the randomPicking() function, from the instantiationtest file, on top of the mouseArea Pressed statement of Button1_1, but i am not being able to do so.
if anyone could provide me any insight i would be pretty thankful
here is the code of the main file
(...)
Window {
id: root
width: Screen.width
height: Screen.height
visible: true
visibility: "FullScreen"
title: qsTr("instantiationTest")
color: "black"
CombosStochasticSelector {}
}
on the combostochasticselector, you can see the following:
Item {
property var model: model1
anchors.fill: parent
id: randomMIDIkeyboardSelector;
property var random: 0;
function randomSelection(min, max) {(...)}
function createMidiKeyboard(itemToBeInstantiated) {
var component = Qt.createComponent(itemToBeInstantiated)
if (component.status === Component.Ready) {
var midiKeyboard = component.createObject(randomMIDIkeyboardSelector, {model: model});
}
else if (component.status === Component.Error) {
}
}
function randomPicking() {
random = parseInt(randomSelection(1, 13));
if(random == 1) {createMidiKeyboard("./../_Combos/Combo1.qml");}
(...)
return random;
}
Component.onCompleted: {
randomPicking();
}
}
on the Button1_1 you can see the following:
import QtQuick 2.6
QMLOpenGLToggleButtonPrimitive {}
It instantiates a press released kind of button made out of Rectangle QML Primitives
kind regards
