   3 A button is a control that contains a text string,
   4 and is one of the commonest elements of a GUI. It may be placed on a
   5 \rtfsp\helpref{dialog box}{wxdialog} or \helpref{panel}{wxpanel}, or indeed
   6 almost any other window.

  89
  90 \membersection{wxButton::SetDefault}\label{wxbuttonsetdefault}
  91
  92 \func{void}{SetDefault}{\void}
  93
  94 This sets the button to be the default item for the panel or dialog
  95 box.
  96
  97 \wxheading{Remarks}
  98
  99 Under Windows, only dialog box buttons respond to this function.  As
 100 normal under Windows and Motif, pressing return causes the default button to
 101 be depressed when the return key is pressed. See also \helpref{wxWindow::SetFocus}{wxwindowsetfocus}\rtfsp
 102 which sets the keyboard focus for windows and text panel items,\rtfsp
 103 and \helpref{wxWindow::GetDefaultItem}{wxwindowgetdefaultitem}.
 104
 105 Note that under Motif, calling this function immediately after
 106 creation of a button and before the creation of other buttons
 107 will cause misalignment of the row of buttons, since default
 108 buttons are larger. To get around this, call {\it SetDefault}\rtfsp
 109 after you have created a row of buttons: wxWindows will
 110 then set the size of all buttons currently on the panel to
 111 the same size.
 112
