sample app producing described TypeErrors
SUMMARY
I created a very basic QML application (attached) that is based on QApplication
(and not QGuiApplication). I then add a Menu with a MenuItem that has a custom
contentItem set. When run the engine will produce a TypeError (though
everything still seems to work):
file:///usr/lib/qt/qml/QtQuick/Controls.2/org.kde.desktop/MenuItem.qml:98:
TypeError: Cannot read property 'height' of null
Similarly, when adding a ComboBox also with customized contentItem then the
engine produces 5 TypeErrors for each instance of the ComboBox:
file:///usr/lib/qt/qml/QtQuick/Controls.2/org.kde.desktop/ComboBox.qml:52:
TypeError: Cannot read property 'pressed' of null
file:///usr/lib/qt/qml/QtQuick/Controls.2/org.kde.desktop/ComboBox.qml:178:
TypeError: Cannot read property 'selectionStart' of null
file:///usr/lib/qt/qml/QtQuick/Controls.2/org.kde.desktop/private/MobileTextActionsToolBar.qml:62:
TypeError: Cannot read property 'selectedText' of null
file:///usr/lib/qt/qml/QtQuick/Controls.2/org.kde.desktop/private/MobileTextActionsToolBar.qml:70:
TypeError: Cannot read property 'selectedText' of null
file:///usr/lib/qt/qml/QtQuick/Controls.2/org.kde.desktop/private/MobileTextActionsToolBar.qml:78:
TypeError: Cannot read property 'canPaste' of null
The TypeError for the MenuItem can be hidden when adding the following line:
arrow: Item {}
I have not figured out a solution to prevent the 5 TypeErrors for the ComboBox.
STEPS TO REPRODUCE
1. Compile attached sample app
2. Run app
3.
OBSERVED RESULT
1 TypeError due to the MenuItem, 5 TypeErrors due to the ComboBox.
EXPECTED RESULT
No TypeErrors.
