GI.Gtk.Objects.AppChooserButton

The AppChooserButton is a widget that lets the user select an application. It implements the AppChooser interface.

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

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

It is possible to add custom items to the list, using appChooserButtonAppendCustomItem. These items cause the AppChooserButton::customItemActivated signal to be emitted when they are selected.

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

Properties

heading

The text to show at the top of the dialog that can be opened from the button. The string may contain Pango markup.

constructAppChooserButtonHeading :: (IsAppChooserButton o, MonadIO m) => Text -> m (GValueConstruct o)

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

getAppChooserButtonHeading :: (MonadIO m, IsAppChooserButton o) => o -> m (Maybe Text)

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

get appChooserButton #heading

setAppChooserButtonHeading :: (MonadIO m, IsAppChooserButton o) => o -> Text -> m ()

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

set appChooserButton [ #heading := value ]

showDefaultItem

The AppChooserButton:showDefaultItem property determines whether the dropdown menu should show the default application on top for the provided content type.

Since: 3.2

constructAppChooserButtonShowDefaultItem :: (IsAppChooserButton o, MonadIO m) => Bool -> m (GValueConstruct o)

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

getAppChooserButtonShowDefaultItem :: (MonadIO m, IsAppChooserButton o) => o -> m Bool

Get the value of the “show-default-item” property. When overloading is enabled, this is equivalent to

get appChooserButton #showDefaultItem

setAppChooserButtonShowDefaultItem :: (MonadIO m, IsAppChooserButton o) => o -> Bool -> m ()

Set the value of the “show-default-item” property. When overloading is enabled, this is equivalent to

set appChooserButton [ #showDefaultItem := value ]

showDialogItem

The AppChooserButton:showDialogItem property determines whether the dropdown menu should show an item that triggers a AppChooserDialog when clicked.

constructAppChooserButtonShowDialogItem :: (IsAppChooserButton o, MonadIO m) => Bool -> m (GValueConstruct o)

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

getAppChooserButtonShowDialogItem :: (MonadIO m, IsAppChooserButton o) => o -> m Bool

Get the value of the “show-dialog-item” property. When overloading is enabled, this is equivalent to

get appChooserButton #showDialogItem

setAppChooserButtonShowDialogItem :: (MonadIO m, IsAppChooserButton o) => o -> Bool -> m ()

Set the value of the “show-dialog-item” property. When overloading is enabled, this is equivalent to

set appChooserButton [ #showDialogItem := value ]

Signals

customItemActivated

type AppChooserButtonCustomItemActivatedCallback

Arguments

 = Text

itemName: the name of the activated item

-> IO ()

Emitted when a custom item, previously added with appChooserButtonAppendCustomItem, is activated from the dropdown menu.

afterAppChooserButtonCustomItemActivated :: (IsAppChooserButton a, MonadIO m) => a -> Maybe Text -> ((?self :: a) => AppChooserButtonCustomItemActivatedCallback) -> m SignalHandlerId

Connect a signal handler for the customItemActivated signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after appChooserButton #customItemActivated callback

This signal admits a optional parameter detail. If it's not Nothing, we will connect to “custom-item-activated::detail” instead.

By default the object invoking the signal is not passed to the callback. If you need to access it, you can use the implit ?self parameter. Note that this requires activating the ImplicitParams GHC extension.

onAppChooserButtonCustomItemActivated :: (IsAppChooserButton a, MonadIO m) => a -> Maybe Text -> ((?self :: a) => AppChooserButtonCustomItemActivatedCallback) -> m SignalHandlerId

Connect a signal handler for the customItemActivated signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on appChooserButton #customItemActivated callback

This signal admits a optional parameter detail. If it's not Nothing, we will connect to “custom-item-activated::detail” instead.
