C++ initializes members in the order in which they are defined in class. So the order is important if the members are accessed by other initializers or methods called from them. Class BoxLayerWidget: _roundRect is initialized based on _layerType through the st() method. Class Checkbox: Arguments of _text constructor depend on _checkAlignment through the countTextMinWidth and the checkRect methods.
