GI.Gdk.Objects.AppLaunchContext
Description
GdkAppLaunchContext handles launching an application in a graphical context.
It is an implementation of GAppLaunchContext that provides startup
notification and allows to launch applications on a specific workspace.
Launching an application
c code
GdkAppLaunchContext *context;
context = gdk_display_get_app_launch_context (display);
gdk_app_launch_context_set_timestamp (gdk_event_get_time (event));
if (!g_app_info_launch_default_for_uri ("http://www.gtk.org", context, &error))
g_warning ("Launching failed: %s\n", error->message);
g_object_unref (context);Synopsis

Exported types
newtype AppLaunchContext Source #
Memory-managed wrapper type.
Constructors
| AppLaunchContext (ManagedPtr AppLaunchContext) |
Instances
class (GObject o, IsDescendantOf AppLaunchContext o) => IsAppLaunchContext o Source #
Type class for types which can be safely cast to AppLaunchContext, for instance with toAppLaunchContext.
Instances
| (GObject o, IsDescendantOf AppLaunchContext o) => IsAppLaunchContext o Source # | |
Defined in GI.Gdk.Objects.AppLaunchContext | |
toAppLaunchContext :: (MonadIO m, IsAppLaunchContext o) => o -> m AppLaunchContext Source #
Cast to AppLaunchContext, for types for which this is known to be safe. For general casts, use castTo.

getDisplay
appLaunchContextGetDisplay Source #
Arguments
| :: (HasCallStack, MonadIO m, IsAppLaunchContext a) | |
| => a |
|
| -> m Display | Returns: the display of |
Gets the GdkDisplay that context is for.
setDesktop
appLaunchContextSetDesktop Source #
Arguments
| :: (HasCallStack, MonadIO m, IsAppLaunchContext a) | |
| => a |
|
| -> Int32 |
|
| -> m () |
Sets the workspace on which applications will be launched.
This only works when running under a window manager that
supports multiple workspaces, as described in the
Extended Window Manager Hints.
Specifically this sets the _NET_WM_DESKTOP property described
in that spec.
This only works when using the X11 backend.
When the workspace is not specified or desktop is set to -1,
it is up to the window manager to pick one, typically it will
be the current workspace.
setIcon
appLaunchContextSetIcon Source #
Arguments
| :: (HasCallStack, MonadIO m, IsAppLaunchContext a, IsIcon b) | |
| => a |
|
| -> Maybe b |
|
| -> m () |
Sets the icon for applications that are launched with this context.
Window Managers can use this information when displaying startup notification.
See also appLaunchContextSetIconName.
setIconName
appLaunchContextSetIconName Source #
Arguments
| :: (HasCallStack, MonadIO m, IsAppLaunchContext a) | |
| => a |
|
| -> Maybe Text |
|
| -> m () |
Sets the icon for applications that are launched with this context.
The iconName will be interpreted in the same way as the Icon field
in desktop files. See also appLaunchContextSetIcon.
If both icon and iconName are set, the iconName takes priority.
If neither icon or iconName is set, the icon is taken from either
the file that is passed to launched application or from the GAppInfo
for the launched application itself.
setTimestamp
appLaunchContextSetTimestamp Source #
Arguments
| :: (HasCallStack, MonadIO m, IsAppLaunchContext a) | |
| => a |
|
| -> Word32 |
|
| -> m () |
Sets the timestamp of context.
The timestamp should ideally be taken from the event that triggered the launch.
Window managers can use this information to avoid moving the focus to the newly launched application when the user is busy typing in another window. This is also known as 'focus stealing prevention'.
Properties
display
The display that the GdkAppLaunchContext is on.
constructAppLaunchContextDisplay :: (IsAppLaunchContext o, MonadIO m, IsDisplay a) => a -> m (GValueConstruct o) Source #
Construct a GValueConstruct with valid value for the “display” property. This is rarely needed directly, but it is used by new.
getAppLaunchContextDisplay :: (MonadIO m, IsAppLaunchContext o) => o -> m Display Source #
Get the value of the “display” property.
When overloading is enabled, this is equivalent to
get appLaunchContext #display
