-wxSizer is the abstract base class used for layouting subwindows in a window. You
-cannot use wxSizer directly; instead, you'll have to use \helpref{wxBoxSizer}{wxboxsizer}
-or \helpref{wxStaticBoxSizer}{wxstaticboxsizer}.

-The layouting algorithm used by sizers in wxWindows closely related to layouting
+wxSizer is the abstract base class used for laying out subwindows in a window. You
+cannot use wxSizer directly; instead, you will have to use one of the sizer
+classes derived from it. Currently there are \helpref{wxBoxSizer}{wxboxsizer},
+\helpref{wxStaticBoxSizer}{wxstaticboxsizer},
+\helpref{wxGridSizer}{wxgridsizer}
+\helpref{wxFlexGridSizer}{wxflexgridsizer} and \helpref{wxGridBagSizer}{wxgridbagsizer}.
+
+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
-the dialog in the beginning, rather the top-most sizer will get queried and it will
-then query its children. Its children can be normal windows or other sizers, so that
-a hierachy of sizer can be constructed. Note that sizer are not derived from wxWindows
-and thus do not interfere with tab ordering and require very little resources compared
+This will most often mean that the programmer does not set the original size of
+a dialog in the beginning, rather the dialog will be assigned a sizer and this sizer
+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
+and thus does not interfere with tab ordering and requires very little resources compared
to a real window on screen.

+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 intial dialog size will automatically be bigger on Motif than on Windows.
+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.
+
+
+Please notice that sizers, like child windows, are owned by the library and
+will be deleted by it which implies that they must be allocated on the heap.
+However if you create a sizer and do not add it to another sizer or window, the
+library wouldn't be able to delete such an orphan sizer and in this, and only
+this, case it should be deleted explicitly.
+
+\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
+here:
\docparam{window}{The window to be added to the sizer. Its initial size (either set explicitly by the
user or calculated internally when using wxDefaultSize) is interpreted as the minimal and in many
-cases also the initial size. This is particularly useful in connection with \helpref{SetSizeHint}{wxsizersetsizehints}. }
+cases also the initial size.}
\docparam{sizer}{The (child-)sizer to be added to the sizer. This allows placing a child sizer in a
sizer and thus to create hierarchies of sizers (typically a vertical box as the top sizer and several
horizontal boxes on the level beneath).}
\docparam{width and height}{The dimension of a spacer to be added to the sizer. Adding spacers to sizers
-gives more flexilibilty in the design of dialogs; imagine for example a vertical box with two buttons at the

bottom of a dialog: you might want to insert a space between the two buttons and make that space stretchable
-using the {\it option} flag and the result will be that the left button will be aligned with the left
+using the \arg{proportion} flag and the result will be that the left button will be aligned with the left
side of the dialog and the right button with the right side - the space in between will shrink and grow with
the dialog.}
-\membersection{wxSizer::Prepend}\label{wxsizerprepend}
+\docparam{proportion}{Although the meaning of this parameter is undefined in wxSizer, it is used in wxBoxSizer
+to indicate if a child of a sizer can change its size in the main orientation of the wxBoxSizer - where
+0 stands for not changeable and a value of more than zero is interpreted relative to the value of other
+children of the same wxBoxSizer. For example, you might have a horizontal wxBoxSizer with three children, two
+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 \arg{border} parameter determines the border width whereas
+the flags given here determine which side(s) of the item that the
+border will be added. The other flags determine how the sizer item
+behaves when the space allotted to the sizer changes, and is somewhat
+dependent on the specific kind of sizer used.

+\func{void}{SetVirtualSizeHints}{\param{wxWindow* }{window}}
+
+Tell the sizer to set the minimal size of the \arg{window} virtual area to match the sizer's
+minimal size. For windows with managed scrollbars this will set them appropriately.

+Shows or hides the \arg{window}, \arg{sizer}, or item at \arg{index}.

+\section{\class{wxSizerFlags}}\label{wxsizerflags}
+
+Normally, when you add an item to a sizer via
+\helpref{wxSizer::Add}{wxsizeradd}, you have to specify a lot of flags and
+parameters which can be unwieldy. This is where wxSizerFlags comes in: it
+allows you to specify all parameters using the named methods instead. For
+example, instead of
+
+\begin{verbatim}
+ sizer->Add(ctrl, 0, wxEXPAND | wxBORDER, 10);
+\end{verbatim}
+
+you can now write
+
+\begin{verbatim}
+ sizer->Add(ctrl, wxSizerFlags().Expand().Border(10));
+\end{verbatim}
+
+This is more readable and also allows you to create wxSizerFlags objects which
+can be reused for several sizer items.
+\begin{verbatim}
+ wxSizerFlags flagsExpand(1);
+ flagsExpand.Expand().Border(10);
+
+ sizer->Add(ctrl1, flagsExpand);
+ sizer->Add(ctrl2, flagsExpand);
+\end{verbatim}
+
+Note that by specification, all methods of wxSizerFlags return the wxSizerFlags
+object itself to allowing chaining multiple methods calls like in the examples
+above.
+
+
+\membersection{wxSizerFlags::wxSizerFlags}\label{wxsizerflagsctor}
+
+\func{}{wxSizerFlags}{\param{int }{proportion = 0}}
+
+Creates the wxSizer with the proportion specified by \arg{proportion}.
+
+
+\membersection{wxSizerFlags::Align}\label{wxsizerflagsalign}
+
+\func{wxSizerFlags\& }{Align}{\param{int }{align = 0}}
+
+Sets the alignment of this wxSizerFlags to \arg{align}.
+
+Note that if this method is not called, the wxSizerFlags has no specified alignment.
