- @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.
+
+ 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.
- To use this class, first add buttons to the sizer by calling AddButton (or
- SetAffirmativeButton, SetNegativeButton,
- or 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.
+ 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.
- 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.
+ 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
+ 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.}

- rows or all columns are not necessarily the same height or width as in
- the wxGridSizer.

+ (if such things exist). By using this class, you can ensure that all your

+ the Windows, GTK+ and Mac OS X human interface guidelines.
- Since wxWidgets 2.5.0, wxFlexGridSizer can also size items equally in one
- direction but unequally ("flexibly") in the other. If the sizer is only
- flexible in one direction (this can be changed using
- wxFlexGridSizer::SetFlexibleDirection),
- it needs to be decided how the sizer should grow in the other ("non-flexible")
- direction in order to fill the available space. The
- wxFlexGridSizer::SetNonFlexibleGrowMode method
- serves this purpose.
+ When there aren't interface guidelines defined for a particular platform or
+ toolkit, wxStdDialogButtonSizer reverts to the Windows implementation.
+
+ 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.
+
+ 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.

/**
- @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.
-
- 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.
-
- @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.
+ @class wxSizerItem
- @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
- 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
- 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
- wxALIGN_CENTRE
- wxALIGN_LEFT
- wxALIGN_RIGHT
- wxALIGN_TOP
- wxALIGN_BOTTOM
- wxALIGN_CENTER_VERTICAL
- wxALIGN_CENTRE_VERTICAL
- wxALIGN_CENTER_HORIZONTAL
- 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.}
