how to set TextField automatically editible without clicking Textfield on qtquick2 - qml

Question

i am trying to create a TextField and when the TextField is appeared i want it to become editible even without clicking the Text area. It appears but without clicking on placeholder text which is text area, it is not becoming active. Here is what i tried
import QtQuick 2.12
import QtQuick.Controls 2.0
Item {
TextField {
id: textFieldTest
placeholderText: "This area should appear as clicked"
anchors.centerIn: parent
focus: true
Component.onCompleted: textFieldTest.forceActiveFocus()
}
}
I've also tried to use
focus: true
and
Component.onCompleted: textFieldTest.forceActiveFocus()
seperately. Also together. But both of them did not work. Which function or feature should i use?

Answer 1

Sometimes, you need to delay it, e.g.
Component.onCompleted: Qt.callLater(textFieldTest.forceActiveFocus)
The reason being, is that other components initializing may also want to change focus. So, you want to delay your request for focus so that "last in wins".

Answer 2

Please share your entire code if possible. It seems some thing else is stealing the focus. In my case this is working:
import QtQuick
import QtQuick.Controls
Window {
width: 640
height: 480
visible: true
title: qsTr("Hello World")
TextField {
id: textFieldTest
placeholderText: "This area should appear as clicked"
anchors.centerIn: parent
focus: true
Component.onCompleted: textFieldTest.forceActiveFocus()
}
}
