Struct gtk::ModelButton [−][src]
pub struct ModelButton(_);
Expand description
GtkModelButton is a button class that can use a GAction
as its model.
In contrast to ToggleButton
or RadioButton
, which can also
be backed by a GAction
via the property::Actionable::action-name
property,
GtkModelButton will adapt its appearance according to the kind of
action it is backed by, and appear either as a plain, check or
radio button.
Model buttons are used when popovers from a menu model with
Popover::from_model()
; they can also be used manually in
a PopoverMenu
.
When the action is specified via the property::Actionable::action-name
and property::Actionable::action-target
properties, the role of the button
(i.e. whether it is a plain, check or radio button) is determined by
the type of the action and doesn’t have to be explicitly specified
with the property::ModelButton::role
property.
The content of the button is specified by the property::ModelButton::text
and property::ModelButton::icon
properties.
The appearance of model buttons can be influenced with the
property::ModelButton::centered
and property::ModelButton::iconic
properties.
Model buttons have built-in support for submenus in PopoverMenu
.
To make a GtkModelButton that opens a submenu when activated, set
the property::ModelButton::menu-name
property. To make a button that goes
back to the parent menu, you should set the property::ModelButton::inverted
property to place the submenu indicator at the opposite side.
Example
⚠️ The following code is in plain ⚠️
modelbutton
├── <child>
╰── check
⚠️ The following code is in plain ⚠️
modelbutton
├── <child>
╰── radio
⚠️ The following code is in plain ⚠️
modelbutton
├── <child>
╰── arrow
GtkModelButton has a main CSS node with name modelbutton, and a subnode, which will have the name check, radio or arrow, depending on the role of the button and whether it has a menu name set.
The subnode is positioned before or after the content nodes and gets the .left or .right style class, depending on where it is located.
⚠️ The following code is in plain ⚠️
button.model
├── <child>
╰── check
Iconic model buttons (see property::ModelButton::iconic
) change the name of
their main node to button and add a .model style class to it. The indicator
subnode is invisible in this case.

Implementations
Creates a new builder-pattern struct instance to construct ModelButton
objects.
This method returns an instance of ModelButtonBuilder
which can be used to create ModelButton
objects.
The state of the button. This is reflecting the state of the associated
GAction
.

Whether to render the button contents centered instead of left-aligned. This property should be set for title-like items.

A gio::Icon
that will be used if iconic appearance for the button is
desired.
A gio::Icon
that will be used if iconic appearance for the button is

If this property is set, the button will show an icon if one is set. If no icon is set, the text will be used. This is typically used for horizontal sections of linked buttons.

from the action and does not have to be set explicitly.
