A wrap sizer lays out its items in a single line, like a box sizer
Once all available space in the primary direction has been used, a new line is added and items are added there.
So a wrap sizer has a primary orientation for adding items, and adds lines as needed in the secondary direction.

A wrap sizer lays out its items in a single line, like a box sizer as long as there is space available in that direction.
__init__(self, orient=HORIZONTAL, flags=WRAPSIZER_DEFAULT_FLAGS)¶
Constructor for a WrapSizer.
orient determines the primary direction of the sizer (the most common case being
HORIZONTAL ). The flags parameter can be a combination of the values
EXTEND_LAST_ON_EACH_LINE which will cause the last item on each line to use any remaining space on that line and
REMOVE_LEADING_SPACES which removes any spacer elements from the beginning of a row.
Both of these flags are on by default.
Implements the calculation of a box sizer’s minimal.
It is used internally only and must not be called by the user. Documented for information.
InformFirstDirection(self, direction, size, availableOtherDir)¶
Not used by an application.
This is the mechanism by which sizers can inform sub-items of the first determined size component. The sub-item can then better determine its size requirements.
True if the information was used (and the sub-item min size was updated).
Can be overridden in the derived classes to treat some normal items as spacers.
This method is used to determine whether the given item should be considered to be a spacer for the purposes of
REMOVE_LEADING_SPACES implementation. By default only returns
True for the real spacers.
