Description
I am using KDE 5. I can often get tons of this error message from log.
file:///usr/lib/qt5/qml/QtQuick/Controls/Button.qml:100: TypeError: Cannot read property of null file:///usr/lib/qt5/qml/QtQuick/Controls/Button.qml:100: TypeError: Cannot read property of null file:///usr/lib/qt5/qml/QtQuick/Controls/Button.qml:100: TypeError: Cannot read property of null file:///usr/lib/qt5/qml/QtQuick/Controls/Button.qml:100: TypeError: Cannot read property of null
So I find that line:
Button.qml:100
Binding {
target: menu
property: "__minimumWidth"
> value: button.__panel.width
}
It seems this line attempted to read width of a null __panel.
I tried to make it be conditional:
Binding {
target: menu
property: "__minimumWidth"
value: button.__panel ? button.__panel.width: 0
}
The 'fix' works perfectly, but I don't know whether it will cause other layout crash or not.
Why it was null? Was it normal? Or it was caused by wrong implementations?
