-@b BestSize: The best size of a widget depends on what kind of widget it is,
-and usually also on the contents of the widget. For example a wxListBox's best
-size will be calculated based on how many items it has, up to a certain limit,
-or a wxButton's best size will be calculated based on its label size, but
-normally won't be smaller than the platform default button size (unless a style
-flag overrides that). Get the picture? There is a special virtual method in the
-C++ window classes called @c DoGetBestSize() that a class needs to override if
-it wants to calculate its own best size based on its content. The default
-@c DoGetBestSize() is designed for use in container windows, such as wxPanel,
-and works something like this:
-
--# If the window has a sizer then it is used to calculate the best size.
--# Otherwise if the window has layout constraints then that is used to
- calculate the best size.
--# Otherwise if the window has children then the best size is set to be large
- enough to show all the children.
--# Otherwise if there are no children then the window's min size will be used
- for the best size.
--# Otherwise if there is no min size set, then the current size is used for the
- best size.
-
-@b MinSize: The min size of a widget is a size that is normally explicitly set
-by the programmer either with the @c SetMinSize() method or the
-@c SetSizeHints() method. Most controls will also set the min size to the size
-given in the control's constructor if a non-default value is passed. Top-level
-windows such as wxFrame will not allow the user to resize the frame below the
-min size.
-
-@b Size: The size of a widget can be explicitly set or fetched with the
-@c SetSize() or @c GetSize() methods. This size value is the size that the
-widget is currently using on screen and is the way to change the size of
-something that is not being managed by a sizer.
-
-@b ClientSize: The client size represents the widget's area inside of any
-borders belonging to the widget and is the area that can be drawn upon in a
-@c EVT_PAINT event. If a widget doesn't have a border then its client size is
-the same as its size.
-
-@b InitialSize: The initial size of a widget is the size given to the
-constructor of the widget, if any. As mentioned above most controls will also
-set this size value as the control's min size. If the size passed to the
-constructor is the default @c wxDefaultSize, or if the size is not fully
-specified (such as wxSize(150,-1)) then most controls will fill in the missing
-size components using the best size and will set the initial size of the
-control to the resulting size.
-
-@b GetEffectiveMinSize(): (formerly @c GetBestFittingSize) A blending of the
-widget's min size and best size, giving precedence to the min size. For
-example, if a widget's min size is set to (150, -1) and the best size is
-(80, 22) then the best fitting size is (150, 22). If the min size is (50, 20)
-then the best fitting size is (50, 20). This method is what is called by the
-sizers when determining what the requirements of each item in the sizer is, and
-is used for calculating the overall minimum needs of the sizer.
-
-@b SetInitialSize(size): (formerly @c SetBestFittingSize) This is a little
-different than the typical size setters. Rather than just setting an
-"initial size" attribute it actually sets the minsize to the value passed in,
-blends that value with the best size, and then sets the size of the widget to
-be the result. So you can consider this method to be a "Smart SetSize". This
-method is what is called by the constructor of most controls to set the minsize
-and initial size of the control.
-
-@b window.Fit(): The @c Fit() method sets the size of a window to fit around
-its children. If it has no children then nothing is done, if it does have
-children then the size of the window is set to the window's best size.
-
-@b sizer.Fit(window): This sets the size of the window to be large enough to
-accommodate the minimum size needed by the sizer, (along with a few other
-constraints...) If the sizer is the one that is assigned to the window then
-this should be equivalent to @c window.Fit().
-
-@b sizer.Layout(): Recalculates the minimum space needed by each item in the
-sizer, and then lays out the items within the space currently allotted to the
-sizer.
-
-@b window.Layout(): If the window has a sizer then it sets the space given to
-the sizer to the current size of the window, which results in a call to
-@c sizer.Layout(). If the window has layout constraints instead of a sizer then
-the constraints algorithm is run. The @c Layout() method is what is called by
-the default @c EVT_SIZE handler for container windows.

+
+@li @b "Size": this is the current size of the window and it can be explicitly
+ set or fetched with the wxWindow::SetSize() or wxWindow::GetSize() methods.
+ This size value is the size that the widget is currently using on screen and is
+ the way to change the size of something that is not being managed by a sizer.
+
+@li @b "Client Size": the client size represents the widget's area inside of any
+ borders belonging to the widget and is the area that can be drawn upon in a
+ @c EVT_PAINT event. For wxFrame, the client size also excludes the frame
+ menu, tool and status bars, if any. If a window doesn't have any border
+ (and is not a wxFrame with some bars) then its client size is the same as
+ its size.
+
+@li @b "Best Size": the best size of a widget depends on what kind of widget it is,
+ and usually also on the contents of the widget. For example a wxListBox's best
+ size will be calculated based on how many items it has, up to a certain limit,
+ or a wxButton's best size will be calculated based on its label size, but
+ normally won't be smaller than the platform default button size (unless a style
+ flag overrides that).
+ There is a special virtual method in the C++ window classes called
+ wxWindow::DoGetBestSize() that a class can override if it wants to calculate
+ its own best size based on its content, however notice that usually it is
+ more convenient to override DoGetBestClientSize(), see below.
+
+@li @b "Best Client Size": this is simply the client size corresponding to the
+ best window size. When the fitting size for the given contents is computed,
+ it will usually be the client size and the size of the borders needs to be
+ added to obtain the full best size. For this reason, it's preferable to
+ override DoGetBestClientSize() and let DoGetBestSize() compute the full
+ best size.
+
+@li @b "Minimal Size": the minimal size of a widget is a size that is normally explicitly
+ set by the programmer either with the wxWindow::SetMinSize() method or with the
+ wxWindow::SetSizeHints() method.
+ Most controls will also set the minimal size to the size given in the control's
+ constructor if a non-default value is passed.
+ Top-level windows such as wxFrame will not allow the user to resize the frame below
+ the minimal size.
+
+@li @b "Maximum Size": just like for the minimal size, the maximum size is normally
+ explicitly set by the programmer with the wxWindow::SetMaxSize() method or
+ with wxWindow::SetSizeHints().
+ Top-level windows such as wxFrame will not allow the user to resize the frame above
+ the maximum size.
+
+@li @b "Initial Size": the initial size of a widget is the size given to the
+ constructor of the widget, if any.
+ As mentioned above most controls will also set this size value as the control's
+ minimal size. If the size passed to the constructor is the default ::wxDefaultSize,
+ or if the size is not fully specified (such as wxSize(150,-1)) then most controls
+ will fill in the missing size components using the best size and will set the
+ initial size of the control to the resulting size.
+
+@li @b "Virtual Size": the virtual size is the size of the potentially viewable
+ area of the widget.
+ The virtual size of a widget may be larger than its actual size and in this
+ case scrollbars will appear to the let the user 'explore' the full contents
+ of the widget.
+ See wxScrolled for more info.

+@section overview_windowsizing_func Functions related to sizing
+
+@li wxWindow::GetEffectiveMinSize(): returns a blending of the widget's minimal size
+ and best size, giving precedence to the minimal size.
+ For example, if a widget's min size is set to (150, -1) and the best size is
+ (80, 22) then the best fitting size is (150, 22). If the min size is (50, 20)
+ then the best fitting size is (50, 20). This method is what is called by the
+ sizers when determining what the requirements of each item in the sizer is,
+ and is used for calculating the overall minimum needs of the sizer.
+
+@li wxWindow::SetInitialSize(): this is a little different than the typical size
+ setters. Rather than just setting an "initial size" attribute it actually sets

+ and then sets the size of the widget to be the result.
+ So you can consider this method to be a "Smart SetSize". This method is what is

+ size of the control.
+
+@li wxWindow::Fit(): this method sets the size of a window to fit around its children.
+ If it has no children then nothing is done, if it does have children then the size
+ of the window is set to the window's best size.
+
+@li wxSizer::Fit(): this sets the size of the window to be large enough to
+ accommodate the minimum size needed by the sizer, (along with a few other

+ the constraints algorithm is run. The @c Layout() method is what is called by
+ the default @c EVT_SIZE handler for container windows.
