Detailed Description

A placeholder message indicating that a list view is empty.

The message comprises a label with lightened text, an optional icon above the text, and an optional button below the text which can be used to easily show the user what to do next to add content to the view.

The top-level component is a ColumnLayout, so additional components items can simply be added as child items and they will be positioned sanely.

Example usage:

import org.kde.kirigami 2.12 as Kirigami

ListView {
    id: listView
    model: [...]
    delegate: [...]

    Kirigami.PlaceholderMessage {
        anchors.centerIn: parent
        width: parent.width - (Kirigami.Units.largeSpacing * 4)

        visible: listView.count == 0

        text: "There are no items in this list"
    }
}
