Struct gtk4::AppChooserButton

source ·
#[repr(transparent)]
pub struct AppChooserButton { /* private fields */ }
Expand description

The AppChooserButton lets the user select an application.

An example GtkAppChooserButton

Initially, a AppChooserButton selects the first application in its list, which will either be the most-recently used application or, if property::AppChooserButton::show-default-item is true, the default application.

The list of applications shown in a AppChooserButton includes the recommended applications for the given content type. When property::AppChooserButton::show-default-item is set, the default application is also included. To let the user chooser other applications, you can set the property::AppChooserButton::show-dialog-item property, which allows to open a full AppChooserDialog.

It is possible to add custom items to the list, using append_custom_item(). These items cause the signal::AppChooserButton::custom-item-activated signal to be emitted when they are selected.

To track changes in the selected application, use the signal::AppChooserButton::changed signal.

CSS nodes

AppChooserButton has a single CSS node with the name “appchooserbutton”.

Implementations

Creates a new AppChooserButton for applications that can handle content of the given type.

Deprecated since 4.10

This widget will be removed in GTK 5

content_type

the content type to show applications for

Returns

a newly created AppChooserButton

Creates a new builder-pattern struct instance to construct AppChooserButton objects.

This method returns an instance of AppChooserButtonBuilder which can be used to create AppChooserButton objects.

Appends a custom item to the list of applications that is shown in the popup.

The item name must be unique per-widget. Clients can use the provided name as a detail for the signal::AppChooserButton::custom-item-activated signal, to add a callback for the activation of a particular custom item in the list.

See also append_separator().

name

the name of the custom item

Sets the text to display at the top of the dialog.

If the heading is not set, the dialog displays a default text.
