handle_set_label

Description:

public virtual signal bool handle_set_label (DBusMethodInvocation invocation, string arg_label, Variant arg_options)

Signal emitted when a remote caller is invoking the SetLabel D-Bus method.

If a signal handler returns true, it means the signal handler will handle the invocation (e.g. take a reference to invocation and eventually call complete_set_label or e.g. return_error on it) and no order signal handlers will run. If no signal handler handles the invocation, the UNKNOWN_METHOD error is returned.

Parameters:

invocation	A DBusMethodInvocation.
arg_label	Argument passed by remote caller.
arg_options	Argument passed by remote caller.

Returns:

true if the invocation was handled, false to let other signal handlers run.
