+The layout algorithm used by sizers in wxWidgets is closely related to layout
in other GUI toolkits, such as Java's AWT, the GTK toolkit or the Qt toolkit. It is
based upon the idea of the individual subwindows reporting their minimal required
size and their ability to get stretched if the size of the parent window has changed.

+This will most often mean that the programmer does not set the original size of

will be queried about the recommended size. The sizer in turn will query its
children, which can be normal windows, empty space or other sizers, so that
a hierarchy of sizers can be constructed. Note that wxSizer does not derive from wxWindow

+What makes sizers so well fitted for use in wxWidgets is the fact that every control
reports its own minimal size and the algorithm can handle differences in font sizes
or different window (dialog item) sizes on different platforms without problems. If e.g.
the standard font as well as the overall design of Motif widgets requires more space than
on Windows, the initial dialog size will automatically be bigger on Motif than on Windows.
+Sizers may also be used to control the layout of custom drawn items on the window. The
+Add, Insert, and Prepend functions return a pointer to the newly added wxSizerItem. Just
+add empty space of the desired size and attributes, and then use the wxSizerItem::GetRect
+method to determine where the drawing operations should take place.
+
+
\pythonnote{If you wish to create a sizer class in wxPython you should
derive the class from {\tt wxPySizer} in order to get Python-aware
capabilities for the various virtual methods.}

Appends a child to the sizer. wxSizer itself is an abstract class, but the parameters are
equivalent in the derived classes that you will instantiate to use it so they are described
of which are supposed to change their size with the sizer. Then the two stretchable windows would get a
value of 1 each to make them grow and shrink equally with the sizer's horizontal dimension.}
-\docparam{flag}{This parameter can be used to set a number of flags which can
-be combined using the binary OR operator |. Two main behaviours are defined
-using these flags. One is the border around a window: the {\it border}
-parameter determines the border width whereas the flags given here determine
-where the border may be (wxTOP, wxBOTTOM, wxLEFT, wxRIGHT or wxALL). The other
-flags determine the child window's behaviour if the size of the sizer changes.
-However this is not - in contrast to the {\it proportion} flag - in the main
-orientation, but in the respectively other orientation. So if you created a
-wxBoxSizer with the wxVERTICAL option, these flags will be relevant if the
-sizer changes its horizontal size. A child may get resized to completely fill
-out the new size (using either wxGROW or wxEXPAND), it may get proportionally
-resized (wxSHAPED), it may get centered (wxALIGN\_CENTER or wxALIGN\_CENTRE)
-or it may get aligned to either side (wxALIGN\_LEFT and wxALIGN\_TOP are set
-to 0 and thus represent the default, wxALIGN\_RIGHT and wxALIGN\_BOTTOM have
-their obvious meaning). With proportional resize, a child may also be centered
-in the main orientation using wxALIGN\_CENTER\_VERTICAL (same as
-wxALIGN\_CENTRE\_VERTICAL) and wxALIGN\_CENTER\_HORIZONTAL (same as
-wxALIGN\_CENTRE\_HORIZONTAL) flags. Finally, you can also specify
-wxADJUST\_MINSIZE flag to make the minimal size of the control dynamically adjust
-to the value returned by its \helpref{GetAdjustedBestSize()}{wxwindowgetadjustedbestsize}
-method - this allows, for example, for correct relayouting of a static text
-control even if its text is changed during run-time.}
