At some places setJustification() is used, at others setJustificationType(). Can’t it be the same everywhere? I would go with setJustification().
setJustification
AttributedString::setJustification()
DrawableText::setJustification()
DrawableText::ValueTreeWrapper::setJustification()
TextEditor::setJustification()
setJustificationType
HyperlinkButton::setJustificationType()
ComboBox::setJustificationType()
Label::setJustificationType()
It’s especially cumbersome when changing a Label to a TextEditor or visa verse.
