Question

Question: How do I use FileChooser to select a file in my ControlFrame.java file? I want to select a file when I select Show Picture from the file menu or when I select Load Sound from the File menu. This question was answered, but I am struggling with finding where it needs to be in my code to work. Please explain where you would put it when selecting Show Picture from the File menu. Do I add it in the event handler when they select Show Picture from the File menu?
