\section{\class{wxRadioButton}}\label{wxradiobutton}
|
|
|
|
A radio button item is a button which usually denotes one of several mutually
|
|
exclusive options. It has a text label next to a (usually) round button.
|
|
|
|
You can create a group of mutually-exclusive radio buttons by specifying {\tt wxRB\_GROUP} for
|
|
the first in the group. The group ends when another radio button group is created, or there are no more radio buttons.
