Description

GtkModelButton is a button class that can use a Action as its model. In contrast to ToggleButton or RadioButton, which can also be backed by a Action via the 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 popoverNewFromModel; they can also be used manually in a PopoverMenu.

When the action is specified via the Actionable:action-name and 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 ModelButton:role property.

The content of the button is specified by the ModelButton:text and ModelButton:icon properties.

The appearance of model buttons can be influenced with the ModelButton:centered and 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 ModelButton:menu-name property. To make a button that goes back to the parent menu, you should set the ModelButton:inverted property to place the submenu indicator at the opposite side.

# CSS nodes

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.

### plain code

button.model
├── <child>
╰── check

Iconic model buttons (see 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.

class GObject o => IsModelButton o Source #

Type class for types which can be safely cast to ModelButton, for instance with toModelButton.

Instances
 Source # Instance detailsDefined in GI.Gtk.Objects.ModelButton Source # Instance detailsDefined in GI.Gtk.Objects.ModelButton

toModelButton :: (MonadIO m, IsModelButton o) => o -> m ModelButton Source #

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

A convenience alias for Nothing :: Maybe ModelButton.

# Methods

## new

Arguments

 :: (HasCallStack, MonadIO m) => m ModelButton Returns: the newly created ModelButton widget

Creates a new GtkModelButton.

Since: 3.16

# Properties

## active

The state of the button. This is reflecting the state of the associated Action.

Since: 3.16

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

getModelButtonActive :: (MonadIO m, IsModelButton o) => o -> m Bool Source #

Get the value of the “active” property. When overloading is enabled, this is equivalent to

get modelButton #active


setModelButtonActive :: (MonadIO m, IsModelButton o) => o -> Bool -> m () Source #

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

set modelButton [ #active := value ]


## centered

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

Since: 3.16

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

getModelButtonCentered :: (MonadIO m, IsModelButton o) => o -> m Bool Source #

Get the value of the “centered” property. When overloading is enabled, this is equivalent to

get modelButton #centered


setModelButtonCentered :: (MonadIO m, IsModelButton o) => o -> Bool -> m () Source #

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

set modelButton [ #centered := value ]


## icon

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

Since: 3.16

clearModelButtonIcon :: (MonadIO m, IsModelButton o) => o -> m () Source #

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

clear #icon


constructModelButtonIcon :: (IsModelButton o, IsIcon a) => a -> IO (GValueConstruct o) Source #
