Detailed Description

A single radio button performs the same basic function as a Gtk::CheckButton, as its position in the object hierarchy reflects.

It is only when multiple radio buttons are grouped together that they become a different user interface component in their own right. Every radio button is a member of some group of radio buttons. When one is selected, all other radio buttons in the same group are deselected. A Gtk::RadioButton gives the user a choice from many options. After constructing the first RadioButton in a group, use get_group() and provide this Group to the constructors ot the other RadioButtons in the same group. To remove a Gtk::RadioButton from one group and make it part of a new one, use set_group().

The RadioButton widget looks like this:

Member Typedef Documentation


Constructor & Destructor Documentation

virtual Gtk::RadioButton::~RadioButton ( ) [virtual]
Gtk::RadioButton::RadioButton ( )
Gtk::RadioButton::RadioButton ( const Glib::ustring label,
bool  mnemonic = false 
) [explicit]
Gtk::RadioButton::RadioButton ( Group group) [explicit]

Create an empty RadioButton belonging to the specified group, into which you can add() a widget.

If you wish to add a Gtk::Label, you may want to use the Gtk::RadioButton(const Group& group, const Glib::ustring& label, bool mnemonic) constructor directly instead.

Gtk::RadioButton::RadioButton ( Group group,
const Glib::ustring label,
bool  mnemonic = false 
)

Create a button belonging to the specified group, with a label inside.

You won't be able to add a widget to this button since it already contains a Gtk::Label.


Member Function Documentation

Group Gtk::RadioButton::get_group ( )

Get the radio button's group.

This group may be passed to the constructors of other radio buttons, or used with set_group().

Returns:
The group to which the radio button belongs.
GtkRadioButton* Gtk::RadioButton::gobj ( ) [inline]

Provides access to the underlying C GtkObject.

Reimplemented from Gtk::CheckButton.

const GtkRadioButton* Gtk::RadioButton::gobj ( ) const [inline]

Provides access to the underlying C GtkObject.

Reimplemented from Gtk::CheckButton.

void Gtk::RadioButton::join_group ( RadioButton group_source)
virtual void Gtk::RadioButton::on_group_changed ( ) [protected, virtual]
void Gtk::RadioButton::reset_group ( )

Remove the radio button from the group.

void Gtk::RadioButton::set_group ( Group group)

Set the radio button's group.

You can obtain a suitable group from another radio button by using get_group().

Returns:
The group to which the radio button should belong.
Glib::SignalProxy0< void > Gtk::RadioButton::signal_group_changed ( )
Prototype:
void on_my_group_changed()

Friends And Related Function Documentation

Gtk::RadioButton* wrap ( GtkRadioButton *  object,
bool  take_copy = false 
) [related]

A Glib::wrap() method for this object.

Parameters:
objectThe C instance.
take_copyFalse if the result should take ownership of the C instance. True if it should take a new copy or ref.
Returns:
A C++ instance that wraps this C instance.
