* SECTION:gtkradiobutton
|
|
* @Short_description: A choice from multiple check buttons
|
|
* @Title: GtkRadioButton
|
|
* @See_also: #GtkComboBox
|
|
*
|
|
* A single radio button performs the same basic function as a #GtkCheckButton,
|
|
* 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
|
|
* #GtkRadioButton is one way of giving the user a choice from many options.
|
|
*
|
|
* Radio button widgets are created with gtk_radio_button_new(), passing %NULL
|
|
* as the argument if this is the first radio button in a group. In subsequent
|
|
* calls, the group you wish to add this button to should be passed as an
|
|
* argument. Optionally, gtk_radio_button_new_with_label() can be used if you
|
|
* want a text label on the radio button.
|
|
*
|
|
* Alternatively, when adding widgets to an existing group of radio buttons,
|
|
* use gtk_radio_button_new_from_widget() with a #GtkRadioButton that already
|
|
* has a group assigned to it. The convenience function
|
|
* gtk_radio_button_new_with_label_from_widget() is also provided.
|
|
*
|
|
* To retrieve the group a #GtkRadioButton is assigned to, use
|
|
* gtk_radio_button_get_group().
|
|
*
|
|
* To remove a #GtkRadioButton from one group and make it part of a new one,
|
|
* use gtk_radio_button_set_group().
|
|
*
|
|
* The group list does not need to be freed, as each #GtkRadioButton will remove
|
|
* itself and its list item when it is destroyed.
|
|
*
|
|
* <example>
|
|
* <title>How to create a group of two radio buttons.</title>
|
|
* <programlisting>
|
|
* void create_radio_buttons (void) {
|
|
*
|
|
* GtkWidget *window, *radio1, *radio2, *box, *entry;
|
|
* window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
|
|
* box = gtk_box_new (GTK_ORIENTATION_VERTICAL, TRUE, 2);
|
|
*
|
|
* /* Create a radio button with a GtkEntry widget */
|
|
* radio1 = gtk_radio_button_new (NULL);
|
|
* entry = gtk_entry_new (<!-- -->);
|
|
* gtk_container_add (GTK_CONTAINER (radio1), entry);
|
|
*
|
|
*
|
|
* /* Create a radio button with a label */
|
|
* radio2 = gtk_radio_button_new_with_label_from_widget (GTK_RADIO_BUTTON (radio1),
|
|
* "I'm the second radio button.");
|
|
*
|
|
* /* Pack them into a box, then show all the widgets */
|
|
* gtk_box_pack_start (GTK_BOX (box), radio1, TRUE, TRUE, 2);
|
|
* gtk_box_pack_start (GTK_BOX (box), radio2, TRUE, TRUE, 2);
|
|
* gtk_container_add (GTK_CONTAINER (window), box);
|
|
* gtk_widget_show_all (window);
|
|
* return;
|
|
* }
|
|
* </programlisting>
|
|
* </example>
|
|
*
|
|
* When an unselected button in the group is clicked the clicked button
|
|
* receives the #GtkToggleButton::toggled signal, as does the previously
|
|
* selected button.
|
|
* Inside the #GtkToggleButton::toggled handler, gtk_toggle_button_get_active()
|
|
* can be used to determine if the button has been selected or deselected.
