Expand description

Trait containing all AppLaunchContext methods.



Provided Methods§


fn display(&self) -> Display

Gets the Display that @self is for.


the display of @self


fn set_desktop(&self, desktop: i32)

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. 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.


the number of a workspace, or -1


fn set_icon(&self, icon: Option<&impl IsA<Icon>>)

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

Window Managers can use this information when displaying startup notification.

See also set_icon_name().


a GIcon


fn set_icon_name(&self, icon_name: Option<&str>)

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 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.


an icon name


fn set_timestamp(&self, timestamp: u32)

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’.


a timestamp
