- GObject::Object
- Reference
- Object
Overview
Integrating the launch with the launching application. This is used to handle for instance startup notification and launching the new application on the same screen as the launching window.

#==(other : self)
Returns
true
if this reference is the same as other. -
#display(info : Gio::AppInfo, files : GLib::List) : String | Nil
Gets the display string for the context.
-
#environment : Enumerable(String)
Gets the complete environment variable list to be passed to the child process when context is used to launch an application.

-
#startup_notify_id(info : Gio::AppInfo, files : GLib::List) : String | Nil
Initiates startup notification for the application and returns the
DESKTOP_STARTUP_ID

Constructor Detail
Creates a new application launch context. This is not normally used, instead you instantiate a subclass of this, such as #Gdk::AppLaunchContext.
Class Method Detail
Returns the type id (GType) registered in GLib type system.
Instance Method Detail
Returns true
if this reference is the same as other. Invokes same?
.
Gets the display string for the context. This is used to ensure new
applications are started on the same display as the launching
application, by setting the DISPLAY
environment variable.
Gets the complete environment variable list to be passed to
the child process when context is used to launch an application.
This is a nil
-terminated array of strings, where each string has
the form KEY=VALUE
.
Called when an application has failed to launch, so that it can cancel the application startup notification started in g_app_launch_context_get_startup_notify_id().
Arranges for variable to be set to value in the child's environment when context is used to launch an application.
Initiates startup notification for the application and returns the
DESKTOP_STARTUP_ID
for the launched operation, if supported.
Startup notification IDs are defined in the FreeDesktop.Org Startup Notifications standard.
Arranges for variable to be unset in the child's environment when context is used to launch an application.
