public class AppLaunchContext extends AppLaunchContext
`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
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);
```

  • Constructor Details

  • Method Details

    • getClassHandler

      public static ClassHandler getClassHandler()

    • getDisplay

      public Display getDisplay()
      Gets the `GdkDisplay` that @context is for.
      Returns:
      the display of @context

    • setDesktop

      public void setDesktop(int desktop)
      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.
      Parameters:
      desktop - the number of a workspace, or -1

    • setIcon

      public void setIcon(@Nullable Icon icon)
      Sets the icon for applications that are launched with this
      context.

      Window Managers can use this information when displaying startup
      notification.

      See also [method@Gdk.AppLaunchContext.set_icon_name].
      Parameters:
      icon - a `GIcon`

    • setIconName

      public void setIconName(@Nullable Str icon_name)
      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 [method@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.
      Parameters:
      icon_name - an icon name

    • setIconName

      public void setIconName(String icon_name)
      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 [method@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.
      Parameters:
      icon_name - an icon name

    • setTimestamp

      public void setTimestamp(int timestamp)
      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'.
      Parameters:
      timestamp - a timestamp

    • getTypeSize
