You can access the parent component of a Swing component using getParent().

See Component.getParent() for details.

In the gui editor, you can edit the custom creation code to call a constructor of your choice. Your panel must still have a no argument blank constructor as it is a bean.

right click your panel->properties->code->custom creation code.

new MyPanel(this)

Or get the parent as mentioned.
