\section{\class{wxToggleButton}}\label{wxtogglebutton}

wxToggleButton is a button that stays pressed when clicked by the user. In
other words, it is similar to \helpref{wxCheckBox}{wxcheckbox} in
functionality but looks like a \helpref{wxButton}{wxbutton}.

Since wxWidgets version 2.9.0 this control emits an update UI event.

You can see wxToggleButton in action in the sixth page of the
\helpref{controls}{samplecontrols} sample.
