Description
The `instanceof` operator does not provide the correct result for the following case.
In this case an own custom component is created and the name of the component is equal to an Quick Control like my own ToolButton in my module `./MyControls`:
import QtQuick 2.15 import QtQuick.Controls 2.15 import QtQuick.Templates 2.15 as T T.ToolButton { id: root text: "Foo" checkable: true implicitWidth: 150 implicitHeight: 50 background: Rectangle { color: root.down ? "red" : "green" } contentItem: Label { text: "%1".arg(root.text) horizontalAlignment: Qt.AlignHCenter verticalAlignment: Qt.AlignVCenter } }
Next I am using my own ToolButton like this:
import QtQuick 2.15 import QtQuick.Window 2.15 import QtQuick.Controls 2.15 import MyControls 1.0 Window { width: 640 height: 480 visible: true title: qsTr("Hello World") ToolButton { id: fooButton anchors.centerIn: parent width: 150 height: 50 visible: true } Label { anchors.top: fooButton.bottom width: 300 height: 50 text: "fooButton instanceof ToolButton => %1".arg(fooButton instanceof ToolButton) background: Rectangle { color: "yellow" } } }
Here the instanceof operator returns 0 for `fooButton instanceof ToolButton` in the text of the `outputLabel`.
Using aliases for imports can be a workaround for this problem but makes code more complex.
