label inside a rectangle

[Linux-Us]

Hi
I am trying to complete q3 from this pdf. I have posted my program below, still now it draws middle line and the top box, but I think the label is not show and it off the screen. To me the program should work fine, do not know where the is going wrong. Please help me out.

public class ProgramHierarchy extends GraphicsProgram {	
	private static final int BOX_WIDTH = 100;
	private static final int BOX_HEIGHT = 26;
	private static final int MIDDLE_LINE_HEIGHT = 26;
	private static final int GAP_BETWEEN_BOXES = 08;
	public void run() {
		placeMiddleLine();
		placeTopBox();
	}
	private void placeMiddleLine() {
		gl middleLine = new gl (getWidth()/2, (getHeight()/2) - (MIDDLE_LINE_HEIGHT)/2 , getWidth()/2, (getHeight()/2) + (MIDDLE_LINE_HEIGHT)/2);
		add(middleLine);
	}
	private void placeTopBox() {
		gr topBox = new gr ((getWidth()/2)-(BOX_WIDTH/2), ((getHeight()/2) - (BOX_HEIGHT)/2)-BOX_HEIGHT , BOX_WIDTH, BOX_HEIGHT);
		add(topBox);
		gla topLabel = new gla ("Program");
		topLabel.setLocation((getWidth()/2) - (topLabel.getWidth()/2), (getHeight()/2) - (MIDDLE_LINE_HEIGHT/2) - (BOX_HEIGHT/2) + (topLabel.getAscent()/2));
		add(topLabel);
	}
}

Hi
I forget to mention that the I even tried to replace the

topLabel.getAscent()/2

with this statement

(topLabel.getAscent()-topLabel.getDescent())/2

I think this is working now, but I am not sure about the method I am using to do this. Any suggestion or advice to this.

Hi
You are perfect my friend, a font is described my three sizes namely ascent, descent and a character width. I am posting this because you should know the basic before implementing it. To measure vertically the first two are used and to measure horizontally the last one is used. It some times happens that the descent is measured by negative numbers or sometimes measured by positive numbers. please refer your manuals for more details. If any problem feel free to post back.
