Required Methods§
sourcefn set_desktop(&self, desktop: i32)
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.
desktop
the number of a workspace, or -1
sourcefn set_icon(&self, icon: Option<&impl IsA<Icon>>)
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()
.
icon
a GIcon
sourcefn set_icon_name(&self, icon_name: Option<&str>)
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.
icon_name
an icon name
sourcefn set_timestamp(&self, timestamp: u32)
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’.
timestamp
a timestamp
