+The layout algorithm used by sizers in wxWindows 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.

\membersection{wxSizer::wxSizer}\label{wxsizerwxsizer}
\func{}{wxSizer}{\void}
deriving directly from wxSizer and this class does not override these methods, the meaning
of the paramters is 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}.}
+
+\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
+side of the dialog and the right button with the right side - the space in between will shrink and grow with
+the dialog.}
+
+\docparam{option}{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 changable and a value of more than zero in interpreted relative to the value of other
+children of the same wxBoxSizer. You might, e.g., 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 vertical 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, but - in contrast to
+the {\it option} flag - not in the main orientation, but 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), may get centered (wxCENTER or wxCENTRE) or 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.}
+
+\docparam{border}{Determines the border width, if the {\it flag} parameter is set to any border.}

\membersection{wxSizer::Remove}\label{wxsizerremove}
Removes a child from the sizer. {\it window} is the window to be removed, {\it sizer} the
equivalent sizer and {\it nth} is the position of the child in the sizer, typically 0 for
-the first item. This method does not cause any layouting or resizing to take place and does
+the first item. This method does not cause any layout or resizing to take place and does
not delete the window itself. Call \helpref{wxSizer::Layout}{wxsizerlayout} for updating
the layout "on screen" after removing a child fom the sizer.
This is commonly done in the constructor of the window itself, see sample in the description
of \helpref{wxBoxSizer}{wxboxsizer} if the window is resizable (as many dialogs under Unix and
frames on probably all platforms).
