Memory-managed wrapper type.

Type class for types which can be safely cast to RadioButton, for instance with toRadioButton.

Cast to RadioButton, for types for which this is known to be safe. For general casts, use castTo.

A convenience alias for Nothing :: Maybe RadioButton.

Retrieves the group assigned to a radio button.

Joins a RadioButton object to the group of another RadioButton object

Use this in language bindings instead of the radioButtonGetGroup and radioButtonSetGroup methods

A common way to set up a group of radio buttons is the following:

C code

 GtkRadioButton *radio_button;
 GtkRadioButton *last_button;

 while (some_condition)
   {
      radio_button = gtk_radio_button_new (NULL);

      gtk_radio_button_join_group (radio_button, last_button);
      last_button = radio_button;
   }

Since: 3.0

Creates a new RadioButton. To be of any practical value, a widget should then be packed into the radio button.

Creates a new RadioButton, adding it to the same group as radioGroupMember. As with radioButtonNew, a widget should be packed into the radio button.

Creates a new RadioButton with a text label.

Creates a new RadioButton with a text label, adding it to the same group as radioGroupMember.

Creates a new RadioButton containing a label, adding it to the same group as group. The label will be created using labelNewWithMnemonic, so underscores in label indicate the mnemonic for the button.

Creates a new RadioButton containing a label. The label will be created using labelNewWithMnemonic, so underscores in label indicate the mnemonic for the button.

Sets a RadioButton’s group. It should be noted that this does not change the layout of your interface in any way, so if you are changing the group, it is likely you will need to re-arrange the user interface to reflect these changes.

Set the value of the “group” property to Nothing. When overloading is enabled, this is equivalent to

clear #group

Construct a GValueConstruct with valid value for the “group” property. This is rarely needed directly, but it is used by new.

Set the value of the “group” property. When overloading is enabled, this is equivalent to

set radioButton [ #group := value ]

Type for the callback on the (unwrapped) C side.

Emitted when the group of radio buttons that a radio button belongs to changes. This is emitted when a radio button switches from being alone to being part of a group of 2 or more buttons, or vice-versa, and when a button is moved from one group of 2 or more buttons to a different one, but not when the composition of the group that a button belongs to changes.

Since: 2.4

Connect a signal handler for the “group-changed” signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after radioButton #groupChanged callback

Wrap the callback into a Closure.

Generate a function pointer callable from C code, from a C_RadioButtonGroupChangedCallback.

A convenience synonym for Nothing :: Maybe RadioButtonGroupChangedCallback.

Connect a signal handler for the “group-changed” signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on radioButton #groupChanged callback

Wrap a RadioButtonGroupChangedCallback into a C_RadioButtonGroupChangedCallback.
