A good answer might be:
Sure. A frame can hold many GUI components.
Two Buttons in a Frame
Let's develop a new program:
- A frame will hold two buttons, one labeled "Red" and the other "Green."
- The FlowLayout layout manager will be used so the buttons will be
nicely positioned in the frame.
- When the button marked "Red" is clicked, the background will turn red.
- When the button marked "Green" is clicked, the background will turn green.
- There will be an event listener that listens to the clicks
from both buttons.
- When the "close button" of the frame is clicked, the application will quit.
- There will be a listener for window events.
This is very close to a previous example program.
It would be sensible to copy that file and edit it for the new application.
as a review of these somewhat confusing GUI implementation details,
let us start from scratch.
Read the description again and decide on the following:
- How many frames are there?
- What GUI components will it contain?
- What objects generate events?
- What objects receive events?
