Can anyone help me? Whenever I ran the codes below, it always returns a blank frame, I don't know where I did wrong. Can you guys help me debug this? I already added the components to the panel, and the panel to the frame, but still it returns a blank output.
Here is the output I'm getting:
While this is what is required.
