Constructor, creating and showing a button.
+The preferred way to create standard buttons is to use default value of
+\arg{label}. If no label is supplied and \arg{id} is one of standard IDs from
+\helpref{this list}{stockitems}, standard label will be used. In addition to
+that, the button will be decorated with stock icons under GTK+ 2.

+
+\func{wxSize}{GetDefaultSize}{\void}
+
+Returns the default size for the buttons. It is advised to make all the dialog
+buttons of the same size and this function allows to retrieve the (platform and
+current font dependent size) which should be the best suited for this.

\func{void}{SetDefault}{\void}
Under Windows, only dialog box buttons respond to this function. As
normal under Windows and Motif, pressing return causes the default button to
be depressed when the return key is pressed. See also \helpref{wxWindow::SetFocus}{wxwindowsetfocus}\rtfsp
-which sets the keyboard focus for windows and text panel items, \helpref{wxWindow::OnDefaultAction}{wxwindowondefaultaction}\rtfsp
-and \helpref{wxWindow::GetDefaultItem}{wxwindowgetdefaultitem}.
+which sets the keyboard focus for windows and text panel items,\rtfsp
+and \helpref{wxTopLevelWindow::SetDefaultItem}{wxtoplevelwindowsetdefaultitem}.
Note that under Motif, calling this function immediately after
creation of a button and before the creation of other buttons
will cause misalignment of the row of buttons, since default
buttons are larger. To get around this, call {\it SetDefault}\rtfsp
-after you have created a row of buttons: wxWindows will
+after you have created a row of buttons: wxWidgets will
then set the size of all buttons currently on the panel to
the same size.
