There is no property "enabled" in my root element which is "window".
here is the first lines of my code

import QtQuick 2.12
import QtQuick.Window 2.12
import QtQuick.VirtualKeyboard 2.4
import QtQuick.Controls 2.5
//import QtQuick.Controls 2.13
//import QtQuick.Controls 1.4

//import "delayfunc.js" as Mydelay

//import "content"
//import "content"

Window {

    id: window
    visible: true
    width: 800
    height: 480
    title: qsTr("Process Control")
  ....
}

other elements are inside this.

ah Window is special, I forgot

A hacky way could be a simply MouseArea to capture the input ?

MouseArea{
id:blockAllInput
anchors.fill: parent
enabled: false
z:100 //to make sure, its above it siblings
}

enable the MouseAre to capture all input disable it for normal function...

Thanks a lot. It works.
But is also prevent me to touch my lock switch again to disable it.

@imhs
if the lock switch is also in main.qml, simply give it a z of > 100
😉

It is in the main.qml but it is not a child of the root (window). I tried it before my last post but it doesn't work.

[J.Hilk]

@imhs mmh,
can you show that part of the main.qml ?

ah yes runStop_switch is not a sibling of the mouse area, as it's a child of buttons the z property only effects the siblings hierarchy

try:

MouseArea{
        id:blockAllInput
        anchors.fill: parent
       z: 100
        onPressed: {
            var adjusted = mapToItem(blockAllInput, runStop_switch.x, runStop_switch.y)
            if(mouseX > adjusted.x && mouseX < adjusted.x + runStop_switch.width)
                if(mouseY > adjusted.y && mouseY < adjusted.y + runStop_switch.height)
                    mouse.accepted = false
        }
    }

that should let the pressed signal through, but not the release, so clicked will not be emitted 🤔
You'll have to adjust that

@J-Hilk said in lock touch screen:

MouseArea{
id:blockAllInput
anchors.fill: parent
z: 100
onPressed: {
var adjusted = mapToItem(blockAllInput, runStop_switch.x, runStop_switch.y)
if(mouseX > adjusted.x && mouseX < adjusted.x + runStop_switch.width)
if(mouseY > adjusted.y && mouseY < adjusted.y + runStop_switch.height)
mouse.accepted = false
}
}

Thank you so much. You gave me the clue. I appreciate your kind help.
