Column Width Matching with Children

shahriar25

Hi. I want to create something like a contextmenu that is a Column and I want the delegate to be a Label and I want the column's width be the delegate's width that has the maximum width among the others. how can I do that?

Hi,

Doesn't QMenu already provide what you need for a contextual menu ?

Hi @SGaist
I know that it does but I want to create my own and more importantly I want to know how to do that because I will need it elsewhere

SGaist

Why do you want to create your own ?

You take a look a QMenu's sources.

Hi @SGaist
I needed it to create something like a dialog
I looked at the QMenu's source but it didn't help. but then I figured it out after some thinking:

import QtQuick 2.7
import QtQuick.Controls 2.0

Rectangle {
id: root
clip: true

color: "cyan"

width: listView.width
height: listView.height

property color textColor: "black"
property var items: [
    "Open", "Save", "Exit"
]

Label{
    id: testLabel

    visible: false

    text: "test"
}

ListView{
    id: listView

    width: 0
    height: (testLabel.height*3/2)*count

    anchors.centerIn: parent

    model: items

    delegate: BaseButton{
        id: base

        mainColor: root.color

        width: label.width+label.height/2
        height: label.height*3/2

        Label{
            id: label

            anchors.centerIn: parent

            text: items[index]

            color: root.textColor
        }

        Component.onCompleted: listView.width = base.width>listView.width ? base.width:listView.width
    }
}

}

Sorry, my bad, I somehow missed that you posted that on the QtQuick sub-forum.
