Class
GdkAppLaunchContext
Description [src]
final class Gdk.AppLaunchContext : Gio.AppLaunchContext
{
/* No available fields */
}
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);
Instance methods
gdk_app_launch_context_set_icon_name
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.
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.
