pub struct ToggleGroup { /* private fields */ }
v1_7
only.Expand description
A group of exclusive toggles.

ToggleGroup
presents a set of exclusive toggles, represented as
Toggle
objects. Each toggle can display an icon, a label, an icon
and a label, or a custom child.
Toggles are indexed by their position, with the first toggle being equivalent
to 0, and so on. Use the active
to get that position.
Toggles can also have optional names, set via the name
property. The name of the active toggle can be accessed via the
active-name
property.
Toggle
objects can be retrieved via their index or name, using
toggle()
or toggle_by_name()
respectively. ToggleGroup
also provides a gtk::SelectionModel
of
its toggles via the toggles
property.
ToggleGroup
is orientable, and the toggles can be displayed horizontally
or vertically. This is mostly useful for icon-only toggles.
Use the homogeneous
property to make the toggles take
the same size, and the can-shrink
to control whether
the toggles can ellipsize.
Example of an ToggleGroup
UI definition:
<object class="AdwToggleGroup">
<property name="active-name">picture</property>
<child>
<object class="AdwToggle">
<property name="icon-name">camera-photo-symbolic</property>
<property name="tooltip" translatable="yes">Picture Mode</property>
<property name="name">picture</property>
</object>
</child>
<child>
<object class="AdwToggle">
<property name="icon-name">camera-video-symbolic</property>
<property name="tooltip" translatable="yes">Recording Mode</property>
<property name="name">recording</property>
</object>
</child>
</object>

§CSS nodes
ToggleGroup
has a main CSS node with the name toggle-group
.
Its toggles have CSS nodes with the name toggle
, and its separators have nodes
with the name separator
.
Toggle nodes will have a different style classes depending on their content:
.text-button
for labels, .image-button
for icons, .image-text-button
for both or no style class for custom children.
The hidden separators use the .hidden
style class.
§Style classes
ToggleGroup
can use the .flat
style class
to remove its background and make it look like a group of buttons.

It can also use the .round
style class to make
its toggles and the group itself rounded.

They can also be combined with each other.

§Accessibility
ToggleGroup
uses the GTK_ACCESSIBLE_ROLE_RADIO_GROUP
role. Its toggles
use the GTK_ACCESSIBLE_ROLE_RADIO
role.
§Properties
§active
The index of the active toggle.
Setting the index to a larger value than the number of toggles in the group unsets the current active toggle.
If no toggle is active, the property will be set to
Gtk::INVALID_LIST_POSITION
.
Readable | Writeable
§active-name
The name of the active toggle.
The name can be set via name
. If the currently active
toggle doesn’t have a name, the property will be set to NULL
.
Set it to NULL
to unset the current active toggle.
Readable | Writeable
§can-shrink
Whether the toggles can be smaller than the natural size of their contents.
If set to TRUE
, the toggle labels will ellipsize.
