==========================================================================================================================================
|phoenix_title| **wx.WrapSizer**
==========================================================================================================================================
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.
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.

================================
================================================================================ ================================================================================
:meth:`~wx.WrapSizer.__init__` Constructor for a :ref:`wx.WrapSizer`.
:meth:`~wx.WrapSizer.CalcMin` Implements the calculation of a box sizer's minimal.
:meth:`~wx.WrapSizer.InformFirstDirection` Not used by an application.
:meth:`~wx.WrapSizer.IsSpaceItem` Can be overridden in the derived classes to treat some normal items as spacers.
:meth:`~wx.WrapSizer.RepositionChildren` Method which must be overridden in the derived sizer classes.

|api| Class API
===============
.. class:: wx.WrapSizer(BoxSizer)
**Possible constructors**::
WrapSizer(orient=HORIZONTAL, flags=WRAPSIZER_DEFAULT_FLAGS)
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.
.. method:: __init__(self, orient=HORIZONTAL, flags=WRAPSIZER_DEFAULT_FLAGS)
Constructor for a :ref:`wx.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.
:param `orient`:
:type `orient`: int
:param `flags`:
:type `flags`: int
.. method:: CalcMin(self)
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.
:rtype: :ref:`wx.Size`
.. method:: 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.
Returns ``True`` if the information was used (and the sub-item min size was updated).
:param `direction`:
:type `direction`: int
:param `size`:
:type `size`: int
:param `availableOtherDir`:
:type `availableOtherDir`: int
:rtype: `bool`
.. method:: IsSpaceItem(self, item)
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.
:param `item`:
:type `item`: wx.SizerItem
:rtype: `bool`
.. method:: RepositionChildren(self, minSize)
Method which must be overridden in the derived sizer classes.
The implementation should reposition the children using the current total size available to the sizer ( ``m_size`` ) and the size computed by the last call to :meth:`CalcMin` .
:param `minSize`:
:type `minSize`: wx.Size
.. versionadded:: 4.1/wxWidgets-3.1.3 ,
before this version RecalcSizes() method not taking any arguments had to be overridden in the derived classes instead.
