Generally I would say it is a questionable design if you have child classes that make assumptions about the members of the parent. It means that your child class can only be used with that specific parent class that will have the expected attributes. If your child class needs to trigger behavior in the parent, a better design would be to have your child class emit signals. This should give you a cleaner separation between the two widgets. It then becomes the responsibility of your parent window to connect to the signals of interest, and perform the required actions as it is notified.
