Description
To reproduce, run the test program and click on the button. I tested with Material theme.
main.qml
import QtQuick 2.8 import QtQuick.Controls 2.1 ApplicationWindow { visible: true width: 640 height: 480 Button { anchors.centerIn: parent text: "Show dialog" onClicked: dialog.open() Dialog { id: dialog width: 250 x: (parent.width - width) / 2 y: (parent.height - height) / 2 footer: DialogButtonBoxStacked { Button { text: "Some text" } Button { text: "Loooooooooooong text" } } } } }
DialogButtonBoxStacked.qml
import QtQuick 2.8 import QtQuick.Templates 2.1 as T import QtQuick.Controls 2.1 import QtQuick.Controls.Material 2.1 T.DialogButtonBox { id: control implicitWidth: Math.max(background ? background.implicitWidth : 0, contentItem.implicitWidth + leftPadding + rightPadding) implicitHeight: Math.max(background ? background.implicitHeight : 0, contentItem.implicitHeight + topPadding + bottomPadding) Material.foreground: Material.accent delegate: Button { flat: true } contentItem: ListView { implicitHeight: contentHeight // This line cause crash model: control.contentModel } }
