+ -# If the window has a sizer then it is used to calculate the best size.
+ -# Otherwise if the window has layout constraints then those are used to
+ calculate the best size.
+ -# Otherwise if the window has children then the best size is set to be large
+ enough to show all the children.
+ -# Otherwise if there are no children then the window's minimal size will be
+ used as its best size.
+ -# Otherwise if there is no minimal size set, then the current size is used
+ for the best size.
