GI.Gtk.Interfaces.AppChooser
Description
AppChooser is an interface that can be implemented by widgets which
allow the user to choose an application (typically for the purpose of
opening a file). The main objects that implement this interface are
AppChooserWidget, AppChooserDialog and AppChooserButton.
Applications are represented by GIO AppInfo objects here.
GIO has a concept of recommended and fallback applications for a
given content type. Recommended applications are those that claim
to handle the content type itself, while fallback also includes
applications that handle a more generic content type. GIO also
knows the default and last-used application for a given content
type. The AppChooserWidget provides detailed control over
whether the shown list of applications should include default,
recommended or fallback applications.
To obtain the application that has been selected in a AppChooser,
use appChooserGetAppInfo.

|
| -> m () |

Properties
contentType
The content type of the AppChooser object.
See [GContentType][gio-GContentType] for more information about content types.
constructAppChooserContentType :: IsAppChooser o => Text -> IO (GValueConstruct o) Source #
Construct a GValueConstruct with valid value for the “content-type” property. This is rarely needed directly, but it is used by new.
getAppChooserContentType :: (MonadIO m, IsAppChooser o) => o -> m (Maybe Text) Source #
Get the value of the “content-type” property.
When overloading is enabled, this is equivalent to
get appChooser #contentType
