Thread: Adding logo into my program

So I am trying to add a logo to my existing program. However nothing shows up when I run it. I am getting no errors and everything else seems to be fine. Can some one tell me what I am missing?

This is just the logo part if you need the whole code it will be separate (just trying to make things easier.

class Logo extends JPanel {
		public Logo() {
			super();
			setPreferredSize(new Dimension(200,200));
		}
		public void paint(Graphics g) {
			g.setColor(Color.red);
			g.fillRoundRect(60,60,110,90,5,5);
			g.setColor(Color.black);
			g.drawString("DEAD BUG", 70, 105);
		}
	}

Here is the entire program.

class Logo extends JPanel {
		public Logo() {
			super();
			setPreferredSize(new Dimension(200,200));
		}
		public void paint(Graphics g) {
			g.setColor(Color.red);

		}
	}

To be honest the instructions for the assignment do not say where it needs to be shown. all I know is that I must have a logo added to the program and it must be seen when the program runs. Other than that it was "keep it as simple as possible". So anywhere is good for me.

I didn't verify which container you are using as the application's main window, but if it's a JFrame, you can set the icon image using setIconImage().

I don not understand what you are telling me. Yes I used JFrame and JLabel. I just want something simple to basically Display a Text based Logo (i.e. "DEAD BUG"). If I use setIconImage(), will it allow for that , and how would I add that to my program. Your suggestion has not been covered in my class so I am not aware of how to use it.

I misunderstood. Usually associating a 'logo' with a program means to feature a graphic or icon somewhere in the program's graphical interface. One way to accomplish that, probably the simplest, is the way I suggested. We are not aware of your limitations unless you tell us, so we're likely to suggest what we know, not what you're allowed to know and/or use.

Inspecting at your code more closely, I see you're making other basic mistakes that should be corrected in order to display a JLabel with the text, "DEAD BUG".

1. Do not override the paint() method as you do in class Logo. Instead, override the paintComponent() method.

2. The default layout for a JFrame is BorderLayout, and components added to a BorderLayout are added to the center of the layout by default.

3. Only one component at a time can occupy a specific layout area, so the last item added is shown while any others previously added become irrelevant. Your code that modifies a component, adds it, modifies it, adds it, etc., is unnecessary.

You should be able to complete your interface as desired by referring to the documentation for BorderLayout and using it properly.

Ok I see what you are saying now. I don't mean to sound like you guys should know what I need. Just some times You guys give suggestions that are way beyond my skill level, and I know for ya'll that is a basic and simple answer to my question. I hate how segmented this class is as I was unaware of the way you suggested until I looked further into my text and see when we talk about drawing and making images. I some times get so lost I am just fusrtated and want to quit, But I don't.

Understand. To help us suggest solutions that are within the bounds of what you can use, try to describe what you're trying to do as specifically as possible including any guidance you've been given or limitations that you're aware of. I know it's hard when you don't know what you don't know, but keep in mind that we don't know what you don't know either.
