+ 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.

- wxORIENTATION_MASK = wxBOTH
-};
+ 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.
-/**
- @class wxStdDialogButtonSizer
+ 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.
- 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.
+ 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.
- When there aren't interface guidelines defined for a particular platform or
- toolkit, wxStdDialogButtonSizer reverts to the Windows implementation.
+ 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.
- 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.
+ @section wxsizer_flags wxSizer flags
- 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.
+ 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
+ wxBOTTOM
+ wxLEFT
+ wxRIGHT
+ 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 behaviour 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
+ wxALIGN_CENTRE
+ wxALIGN_LEFT
+ wxALIGN_RIGHT
+ wxALIGN_TOP
+ wxALIGN_BOTTOM
+ wxALIGN_CENTER_VERTICAL
+ wxALIGN_CENTRE_VERTICAL
+ wxALIGN_CENTER_HORIZONTAL
+ 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.}

- its children, which can be normal windows, empty space or other sizers, so that

- What makes sizers so well fitted for use in wxWidgets is the fact that every

- 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.
+ This only makes sense when @a window is actually a wxTopLevelWindow such
+ as a wxFrame or a wxDialog, since SetSizeHints only has any effect in these classes.

- 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

- should take place.

+ and ordering defined by the platform or toolkit's user interface guidelines

+ standard dialogs look correct on all major platforms. Currently it conforms to

- in the derived classes that you will instantiate to use it so they are
- described here.
+ When there aren't interface guidelines defined for a particular platform or
+ toolkit, wxStdDialogButtonSizer reverts to the Windows implementation.
- @a width and @a height specify the dimension of a spacer to be added to
- the sizer. Adding spacers to sizers gives more flexibility in the
- design of dialogs; imagine for example a horizontal 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
- 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.
+ 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.
