3A button is a control that contains a text string,
4and 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
6almost any other window.

66
67\docparam{pos}{Button position.}
68
69\docparam{size}{Button size. If the default size (-1, -1) is specified then the button is sized
70appropriately for the text.}

93
94Button creation function for two-step creation. For more details, see \helpref{wxButton::wxButton}{wxbuttonconstr}.
95
96\membersection{wxButton::GetLabel}\label{wxbuttongetlabel}
97
98\constfunc{wxString}{GetLabel}{\void}
99
100Returns the string label for the button.
101
102\wxheading{Return value}
103
104The button's label.

109
110\membersection{wxButton::GetDefaultSize}\label{wxbuttongetdefaultsize}
111
112\func{wxSize}{GetDefaultSize}{\void}
113
114Returns the default size for the buttons. It is advised to make all the dialog
115buttons of the same size and this function allows to retrieve the (platform and
116current font dependent size) which should be the best suited for this.
117
118\membersection{wxButton::SetDefault}\label{wxbuttonsetdefault}
119
120\func{void}{SetDefault}{\void}
121
122This sets the button to be the default item for the panel or dialog
123box.
124
125\wxheading{Remarks}
126
127Under Windows, only dialog box buttons respond to this function. As
128normal under Windows and Motif, pressing return causes the default button to
129be depressed when the return key is pressed. See also \helpref{wxWindow::SetFocus}{wxwindowsetfocus}\rtfsp
130which sets the keyboard focus for windows and text panel items,\rtfsp
131and \helpref{wxPanel::SetDefaultItem}{wxpanelsetdefaultitem}.
132
133Note that under Motif, calling this function immediately after
134creation of a button and before the creation of other buttons
135will cause misalignment of the row of buttons, since default
136buttons are larger. To get around this, call {\it SetDefault}\rtfsp
137after you have created a row of buttons: wxWidgets will
138then set the size of all buttons currently on the panel to
139the same size.
140
141\membersection{wxButton::SetLabel}\label{wxbuttonsetlabel}
142
143\func{void}{SetLabel}{\param{const wxString\& }{label}}
144
145Sets the string label for the button.
146
147\wxheading{Parameters}
148
149\docparam{label}{The label to set.}
