GdkAppLaunchContext

Description [src] 

final class Gdk.AppLaunchContext : Gio.AppLaunchContext
{
  /* No available fields */
}

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

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);

gdk_app_launch_context_set_icon

Sets the icon for applications that are launched with this context.

Methods inherited from GAppLaunchContext (6)
g_app_launch_context_get_display

Gets the display string for the context. This is used to ensure new applications are started on the same display as the launching application, by setting the DISPLAY environment variable.

g_app_launch_context_get_environment

Gets the complete environment variable list to be passed to the child process when context is used to launch an application. This is a NULL-terminated array of strings, where each string has the form KEY=VALUE.

g_app_launch_context_get_startup_notify_id

Initiates startup notification for the application and returns the XDG_ACTIVATION_TOKEN or DESKTOP_STARTUP_ID for the launched operation, if supported.

g_app_launch_context_launch_failed

Called when an application has failed to launch, so that it can cancel the application startup notification started in g_app_launch_context_get_startup_notify_id().

g_app_launch_context_setenv

Arranges for variable to be set to value in the child’s environment when context is used to launch an application.

g_app_launch_context_unsetenv

Arranges for variable to be unset in the child’s environment when context is used to launch an application.

The display that the GdkAppLaunchContext is on.

Signals

Signals inherited from GAppLaunchContext (3)
GAppLaunchContext::launch-failed

The GAppLaunchContext::launch-failed signal is emitted when a GAppInfo launch fails. The startup notification id is provided, so that the launcher can cancel the startup notification.

GAppLaunchContext::launch-started

The GAppLaunchContext::launch-started signal is emitted when a GAppInfo is about to be launched. If non-null the platform_data is an GVariant dictionary mapping strings to variants (ie a{sv}), which contains additional, platform-specific data about this launch. On UNIX, at least the startup-notification-id keys will be present.

GAppLaunchContext::launched

The GAppLaunchContext::launched signal is emitted when a GAppInfo is successfully launched.

Signals inherited from GObject (1)
GObject::notify

The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
