Class Details

class Gdk.AppLaunchContext(**kwargs)
Bases:Gio.AppLaunchContext
Abstract:No

Gdk.AppLaunchContext is an implementation of Gio.AppLaunchContext that handles launching an application in a graphical context. It provides startup notification and allows to launch applications on a specific screen or workspace.

Launching an application
GdkAppLaunchContext *context;

context = gdk_display_get_app_launch_context (display);

gdk_app_launch_context_set_screen (screen);
gdk_app_launch_context_set_timestamp (event->time);

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);
classmethod new()[source]
Returns:a new Gdk.AppLaunchContext
Return type:Gdk.AppLaunchContext

Creates a new Gdk.AppLaunchContext.

New in version 2.14.

Deprecated since version 3.0: Use Gdk.Display.get_app_launch_context() instead

set_desktop(desktop)[source]
Parameters:desktop (int) – the number of a workspace, or -1

Sets the workspace on which applications will be launched when using this context when running under a window manager that supports multiple workspaces, as described in the Extended Window Manager Hints.

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.

New in version 2.14.

set_display(display)[source]
Parameters:display (Gdk.Display) – a Gdk.Display

Sets the display on which applications will be launched when using this context. See also Gdk.AppLaunchContext.set_screen().

New in version 2.14.

Deprecated since version 3.0: Use Gdk.Display.get_app_launch_context() instead

set_icon(icon)[source]
Parameters:icon (Gio.Icon or None) – a Gio.Icon, or None

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

Window Managers can use this information when displaying startup notification.

See also Gdk.AppLaunchContext.set_icon_name().

New in version 2.14.

set_icon_name(icon_name)[source]
Parameters:icon_name (str or None) – an icon name, or None

Sets the icon for applications that are launched with this context. The icon_name will be interpreted in the same way as the Icon field in desktop files. See also Gdk.AppLaunchContext.set_icon().

If both icon and icon_name are set, the icon_name takes priority. If neither icon or icon_name is set, the icon is taken from either the file that is passed to launched application or from the Gio.AppInfo for the launched application itself.

New in version 2.14.

set_screen(screen)[source]
Parameters:screen (Gdk.Screen) – a Gdk.Screen

Sets the screen on which applications will be launched when using this context. See also Gdk.AppLaunchContext.set_display().

If both screen and display are set, the screen takes priority. If neither screen or display are set, the default screen and display are used.

New in version 2.14.

set_timestamp(timestamp)[source]
Parameters:timestamp (int) – a timestamp

Sets the timestamp of self. 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’.

New in version 2.14.
