Text Masking in TextField

[Veeresh Veer]

Without key event can i do passwordmaskdelay for Text? and Is there chance of generating key event without using keyboard keys manually???
I tried by using passwordmaskdelay property ,it is not working for my code because i'm using the customized button.

TextField {
    id: inputtext
    color: "red"
    width:300;height:100
    anchors.centerIn: parent
    echoMode: TextInput.Password
    passwordMaskDelay: 3000
    horizontalAlignment: TextInput.Center
}
Button{
    id:btn
    height:100
    width: 100
    text: "1"
    onClicked:{
        console.log("button clicked  = "+btn.text)
        inputtext.text+=btn.text
    }
}

use insert function of TextField

import QtQuick 2.12
import QtQuick.Controls 2.14

Rectangle {
    anchors.fill: parent;
    //I added this button
    TextField {
        id: inputtext
        color: "red"
        width:300;height:100
        anchors.centerIn: parent
        echoMode: TextInput.Password
        passwordMaskDelay: 3000
        horizontalAlignment: TextInput.Center
    }
    Button {
        id:btn
        height:100
        width: 100
        text: "1"
        onClicked: {
            console.log("button clicked  = "+btn.text)
            inputtext.insert(inputtext.length ,btn.text)
        }
    }
}
