GtkStatusbar::pop

pop() removes the message that is currently at the top of the statusbar's stack, using the context_id to identify the message.

When a message is removed from the stack, the memory that was allocated to it is freed. Given that all messages are generated uniquely, it is good practice to pop() the current message before appending the next. Allowing the stack to build up can add considerably to processing time.

This method causes the "text-popped" signal to be emitted.
