RadioButton

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 RB_GROUP for the first in the group. The group ends when another radio button group is created, or there are no more radio buttons.

Window Styles

This class supports the following styles:

• RB_GROUP: Marks the beginning of a new group of radio buttons.
• RB_SINGLE: In some circumstances, radio buttons that are not consecutive siblings trigger a hang bug in Windows (only). If this happens, add this style to mark the button as not belonging to a group, and implement the mutually-exclusive group behaviour yourself.

Events Emitted by this Class

Handlers bound for the following event types will receive a CommandEvent parameter.

• EVT_RADIOBUTTON: Process a wxEVT_COMMAND_RADIOBUTTON_SELECTED event, when the radiobutton is clicked.

Return type:

bool

---

GetValue(self)

Returns True if the radio button is checked, False otherwise.

Return type:bool

---

SetValue(self, value)

Sets the radio button to checked or unchecked status.

This does not cause a wxEVT_COMMAND_RADIOBUTTON_SELECTED event to get emitted.

If the radio button belongs to a radio group exactly one button in the group may be checked and so this method can be only called with value set to True. To uncheck a radio button in a group you must check another button in the same group.

Parameters:value (bool) – True to check, False to uncheck.
