Constructor Detail

def self.new : self #

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

def self.g_type : UInt64 #

Returns the type id (GType) registered in GLib type system.


Instance Method Detail

def display(info : Gio::AppInfo, files : GLib::List) : String? #

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.


def environment : Enumerable(String) #

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.


def launch_failed(startup_notify_id : String) : Nil #

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().


def launch_failed_signal #

def launch_started_signal #

def launched_signal #

def setenv(variable : String, value : String) : Nil #

Arranges for @variable to be set to @value in the child's environment when @context is used to launch an application.


def startup_notify_id(info : Gio::AppInfo, files : GLib::List) : String? #

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.


def unsetenv(variable : String) : Nil #

Arranges for @variable to be unset in the child's environment when @context is used to launch an application.
