-    @class wxStdDialogButtonSizer
+    @class wxSizer

 
 

-    This class creates button layouts which conform to the standard button spacing
-    and ordering defined by the platform or toolkit's user interface guidelines
-    (if such things exist). By using this class, you can ensure that all your
-    standard dialogs look correct on all major platforms. Currently it conforms to
-    the Windows, GTK+ and Mac OS X human interface guidelines.
+    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 wxBoxSizer, wxStaticBoxSizer,
+    wxGridSizer, wxFlexGridSizer, wxWrapSizer and wxGridBagSizer.

 
 

-    When there aren't interface guidelines defined for a particular platform or
-    toolkit, wxStdDialogButtonSizer reverts to the Windows implementation.
+    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.

 
 

-    To use this class, first add buttons to the sizer by calling
-    wxStdDialogButtonSizer::AddButton (or wxStdDialogButtonSizer::SetAffirmativeButton,
-    wxStdDialogButtonSizer::SetNegativeButton or wxStdDialogButtonSizer::SetCancelButton)
-    and then call Realize in order to create the actual button layout used.
-    Other than these special operations, this sizer works like any other sizer.
+    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.

 
 

-    If you add a button with wxID_SAVE, on Mac OS X the button will be renamed to
-    "Save" and the wxID_NO button will be renamed to "Don't Save" in accordance
-    with the Mac OS X Human Interface Guidelines.
+    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 wxSizer::Add(), wxSizer::Insert(), and wxSizer::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.
+
+    @beginWxPythonOnly
+    If you wish to create a sizer class in wxPython you should
+    derive the class from @c wxPySizer in order to get Python-aware
+    capabilities for the various virtual methods.
+    @endWxPythonOnly
+
+    @section wxsizer_flags wxSizer flags
+
+    The "flag" argument accepted by wxSizeItem constructors and other
+    functions, e.g. wxSizer::Add(), is OR-combination of the following flags.
+    Two main behaviours are defined using these flags. One is the border around
+    a window: the 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.
+
+    @beginDefList
+    @itemdef{wxTOP<br>
+             wxBOTTOM<br>
+             wxLEFT<br>
+             wxRIGHT<br>
+             wxALL,
+             These flags are used to specify which side(s) of the sizer item
+             the border width will apply to.}
+    @itemdef{wxEXPAND,
+             The item will be expanded to fill the space assigned to the item.}
+    @itemdef{wxSHAPED,
+             The item will be expanded as much as possible while also
+             maintaining its aspect ratio.}
+    @itemdef{wxFIXED_MINSIZE,
+             Normally wxSizers will use GetAdjustedBestSize() to determine what
+             the minimal size of window items should be, and will use that size
+             to calculate the layout. This allows layouts to adjust when an
+             item changes and its best size becomes different. If you would
+             rather have a window item stay the size it started with then use
+             @c wxFIXED_MINSIZE.}
+    @itemdef{wxRESERVE_SPACE_EVEN_IF_HIDDEN,
+             Normally wxSizers don't allocate space for hidden windows or other
+             items. This flag overrides this behavior so that sufficient space
+             is allocated for the window even if it isn't visible. This makes
+             it possible to dynamically show and hide controls without resizing
+             parent dialog, for example. (Available since 2.8.8.)}
+    @itemdef{wxALIGN_CENTER<br>
+             wxALIGN_CENTRE<br>
+             wxALIGN_LEFT<br>
+             wxALIGN_RIGHT<br>
+             wxALIGN_TOP<br>
+             wxALIGN_BOTTOM<br>
+             wxALIGN_CENTER_VERTICAL<br>
+             wxALIGN_CENTRE_VERTICAL<br>
+             wxALIGN_CENTER_HORIZONTAL<br>
+             wxALIGN_CENTRE_HORIZONTAL,
+             The @c wxALIGN_* flags allow you to specify the alignment of the item
+             within the space allotted to it by the sizer, adjusted for the
+             border if any.}

 /**
 /**

-    @class wxSizer
-
-    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 wxBoxSizer,
-    wxStaticBoxSizer,
-    wxGridSizer,
-    wxFlexGridSizer,
-    wxWrapSizer
-     and 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
-    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 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.
+    @class wxStdDialogButtonSizer

 
 

-    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.
+    This class creates button layouts which conform to the standard button spacing
+    and ordering defined by the platform or toolkit's user interface guidelines
+    (if such things exist). By using this class, you can ensure that all your
+    standard dialogs look correct on all major platforms. Currently it conforms to
+    the Windows, GTK+ and Mac OS X human interface guidelines.

 
 

-    @b wxPython note: If you wish to create a sizer class in wxPython you should
-    derive the class from @c wxPySizer in order to get Python-aware
-    capabilities for the various virtual methods.
+    When there aren't interface guidelines defined for a particular platform or
+    toolkit, wxStdDialogButtonSizer reverts to the Windows implementation.

 
 

-    @anchor wxsizer_flags
-    @par wxSizer flags
-    The "flag" argument accepted by wxSizeItem constructors and other
-    functions, e.g. wxSizer::Add(), is OR-combination of the following flags.
-    Two main behaviours are defined using these flags. One is the border around
-    a window: the 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.
-    @beginDefList
-    @itemdef{wxTOP<br>
-             wxBOTTOM<br>
-             wxLEFT<br>
-             wxRIGHT<br>
-             wxALL,
-             These flags are used to specify which side(s) of the sizer item
-             the border width will apply to.}
-    @itemdef{wxEXPAND,
-             The item will be expanded to fill the space assigned to the item.}
-    @itemdef{wxSHAPED,
-             The item will be expanded as much as possible while also
-             maintaining its aspect ratio.}
-    @itemdef{wxFIXED_MINSIZE,
-             Normally wxSizers will use GetAdjustedBestSize() to determine what
-             the minimal size of window items should be, and will use that size
-             to calculate the layout. This allows layouts to adjust when an
-             item changes and its best size becomes different. If you would
-             rather have a window item stay the size it started with then use
-             wxFIXED_MINSIZE.}
-    @itemdef{wxRESERVE_SPACE_EVEN_IF_HIDDEN,
-             Normally wxSizers don't allocate space for hidden windows or other
-             items. This flag overrides this behavior so that sufficient space
-             is allocated for the window even if it isn't visible. This makes
-             it possible to dynamically show and hide controls without resizing
-             parent dialog, for example. (Available since 2.8.8.)
-             }
-    @itemdef{wxALIGN_CENTER<br>
-             wxALIGN_CENTRE<br>

-             wxALIGN_RIGHT<br>
-             wxALIGN_TOP<br>
-             wxALIGN_BOTTOM<br>
-             wxALIGN_CENTER_VERTICAL<br>
-             wxALIGN_CENTRE_VERTICAL<br>
-             wxALIGN_CENTER_HORIZONTAL<br>
-             wxALIGN_CENTRE_HORIZONTAL,
-             The wxALIGN flags allow you to specify the alignment of the item
-             within the space allotted to it by the sizer, adjusted for the
-             border if any.}
-    @endDefList
+    To use this class, first add buttons to the sizer by calling
+    wxStdDialogButtonSizer::AddButton (or wxStdDialogButtonSizer::SetAffirmativeButton,
