Struct gtk::RadioButton
source · [−]#[repr(transparent)]pub struct RadioButton { /* private fields */ }
Expand description
A single radio button performs the same basic function as a 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
RadioButton
is one way of giving the user a choice from many options.
Radio button widgets are created with new()
, passing None
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, 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 from_widget()
with a RadioButton
that already
has a group assigned to it. The convenience function
with_label_from_widget()
is also provided.
To retrieve the group a RadioButton
is assigned to, use
RadioButtonExt::group()
.
To remove a RadioButton
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 RadioButton
will remove
itself and its list item when it is destroyed.
CSS nodes
⚠️ The following code is in plain ⚠️
radiobutton
├── radio
╰── <child>
A GtkRadioButton with indicator (see ToggleButtonExt::set_mode()
) has a
main CSS node with name radiobutton and a subnode with name radio.
⚠️ The following code is in plain ⚠️
button.radio
├── radio
╰── <child>
A GtkRadioButton without indicator changes the name of its main node to button and adds a .radio style class to it. The subnode is invisible in this case.
How to create a group of two radio buttons.
⚠️ The following code is in C ⚠️
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, 2);
gtk_box_set_homogeneous (GTK_BOX (box), TRUE);
// 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);
gtk_box_pack_start (GTK_BOX (box), radio2);
gtk_container_add (GTK_CONTAINER (window), box);
gtk_widget_show_all (window);
return;
}
When an unselected button in the group is clicked the clicked button
receives the signal::ToggleButton::toggled
signal, as does the previously
selected button.
Inside the signal::ToggleButton::toggled
handler, ToggleButtonExt::is_active()
can be used to determine if the button has been selected or deselected.

Implementations
sourceimpl RadioButton
impl RadioButton
pub const NONE: Option<&'static RadioButton> = None
sourcepub fn from_widget(radio_group_member: &impl IsA<RadioButton>) -> RadioButton
pub fn from_widget(radio_group_member: &impl IsA<RadioButton>) -> RadioButton
Creates a new RadioButton
, adding it to the same group as
radio_group_member
. As with new()
, a widget
should be packed into the radio button.
radio_group_member
an existing RadioButton
.
Returns
a new radio button.
sourcepub fn with_label_from_widget(
radio_group_member: &impl IsA<RadioButton>,
label: &str
) -> RadioButton
pub fn with_label_from_widget(
radio_group_member: &impl IsA<RadioButton>,
label: &str
) -> RadioButton
Creates a new RadioButton
with a text label, adding it to
the same group as radio_group_member
.
radio_group_member
widget to get radio group from or None
label
a text string to display next to the radio button.
Returns
a new radio button.
sourcepub fn with_mnemonic_from_widget(
radio_group_member: &impl IsA<RadioButton>,
label: &str
) -> RadioButton
pub fn with_mnemonic_from_widget(
radio_group_member: &impl IsA<RadioButton>,
label: &str
) -> RadioButton
Creates a new RadioButton
containing a label. The label
will be created using Label::with_mnemonic()
, so underscores
in label
indicate the mnemonic for the button.
radio_group_member
widget to get radio group from or None
label
the text of the button, with an underscore in front of the mnemonic character
Returns
a new RadioButton
sourcepub fn builder() -> RadioButtonBuilder
pub fn builder() -> RadioButtonBuilder
Creates a new builder-pattern struct instance to construct RadioButton
objects.
This method returns an instance of RadioButtonBuilder
which can be used to create RadioButton
objects.
sourceimpl RadioButton
impl RadioButton
sourcepub fn new() -> Self
pub fn new() -> Self
Creates a new RadioButton
. To be of any practical value, a widget should
then be packed into the radio button.
group
an existing
radio button group, or None
if you are creating a new group.
Returns
a new radio button
sourcepub fn with_label(label: &str) -> Self
pub fn with_label(label: &str) -> Self
Creates a new RadioButton
with a text label.
group
an existing
radio button group, or None
if you are creating a new group.
label
the text label to display next to the radio button.
Returns
a new radio button.
sourcepub fn with_mnemonic(label: &str) -> Self
pub fn with_mnemonic(label: &str) -> Self
Creates a new RadioButton
containing a label, adding it to the same
group as group
. The label will be created using
Label::with_mnemonic()
, so underscores in label
indicate the
mnemonic for the button.
group
the radio button
group, or None
label
the text of the button, with an underscore in front of the mnemonic character
Returns
a new RadioButton
