(Java) Explicitly/programmatically closing JPanel

Question

Let's say I have a class which extends JPanel:

class StockScreenResultsPanel extends JPanel{
    etc...
}

Then I have a handle on that class I have just retrieved it from a parent tab:

StockScreenResultsPanel childComponent = (StockScreenResultsPanel)nasdaqTab.getComponent(); 

I'm very sorry if this is really nooby, but I want to explicitly close childComponent (not just hide it but eliminate it from the application), and I can't find any examples.

Can someone show me how to explicitly/programmatically close a child JPanel?

I have already tried the code below and get the error "StockScreenResultsPanel cannot be converted to window"

childComponent.dispatchEvent(new WindowEvent( (Window)childComponent , WindowEvent.WINDOW_CLOSING));

Also, if I try:

childComponent.dispose() 

It gives me a "cannot find symbol".

As the comments in response to my question above say, you can't close a panel, you have to use remove instead.
