Now before you start yelling and screaming at me for breaking all your
code, take note that up above I said, "...using the new wx namespace..."
That's because if you are still importing from wxPython.wx then there
are some classes defined there with Draw and etc. methods that have
2.4 compatible signatures. However if/when the old wxPython.wx
namespace is removed then these classes will be removed too so you
should plan on migrating to the new namespace and new DC Draw methods
before that time.
code, take note that up above I said, "...using the new wx
namespace..." That's because if you are still importing from
wxPython.wx then there are some classes defined there with Draw and
etc. methods that have 2.4 compatible signatures. Unfortunately there
is one exception to this behaviour. If a DC is returned from a
function or method then an instance of the new class (with the new
methods described above) will be returned instead of the compatibility
class. If/When the old wxPython.wx namespace is removed then these
compatibility classes will be removed too so you should plan on

When adding a spacer to a sizer you now need to use a wx.Size or a
2-integer sequence instead of separate width and height parameters.
This allows for more consistency in how you add the various types of
items to a sizer. The first parameter defines the item (instead of
the possibily first two, depending on if you are doing a spacer or
not,) and that item can either be a window, a sizer or a spacer (which
can be a sequence or a wx.Size.)
The wx.GridBagSizer class (very similar to the RowColSizer in the
library) has been added to C++ and wrapped for wxPython. It can also

**[Changed in 2.5.1.6]** wx.ADJUST_MINSIZE is now the default
behaviour for window items in sizers. This means that the item's
GetAdjustedBestSize will be called when calculating layout and the
return value from that will be used for the minimum size. Added
wx.FIXED_SIZE flag for when you would like the old behavior but you
should only need it when your desired size is smaller than the item's
GetBestSize().
