AppLaunchContext
===================================================================

.. currentmodule:: gi.repository.Gdk





.. class:: AppLaunchContext(**properties: ~typing.Any)
   :no-contents-entry:


Superclasses: :class:`~gi.repository.Gio.AppLaunchContext`, :class:`~gi.repository.GObject.Object`





``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
--------------------------------------------------------------------------------


.. code-block:: c
    :dedent:

    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);




Methods
-------

.. rst-class:: interim-class

.. class:: AppLaunchContext
   :no-index:


   .. method:: get_display() -> ~gi.repository.Gdk.Display

      Gets the ``GdkDisplay`` that ``context`` is for.









   .. method:: set_desktop(desktop: int) -> None

      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 <http://www.freedesktop.org/Standards/wm-spec>`__\.
      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.






      :param desktop: the number of a workspace, or -1




   .. method:: set_icon(icon: ~gi.repository.Gio.Icon | None = None) -> None

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

      Window Managers can use this information when displaying startup
      notification.

      See also :obj:`~gi.repository.Gdk.AppLaunchContext.set_icon_name`\.






      :param icon: a ``GIcon``




   .. method:: set_icon_name(icon_name: str | None = None) -> 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 :obj:`~gi.repository.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 ``GAppInfo``
      for the launched application itself.






      :param icon_name: an icon name




   .. method:: set_timestamp(timestamp: int) -> None

      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'.






      :param timestamp: a timestamp
