    <p>I'm trying to build a pyramid in Java using GRect. I use getWidth() to position the pyramid in the center of the canvas but it tends to trip the left part of pyramid.</p> <p>I'm learning programming through <a href="http://see.stanford.edu/see/courseinfo.aspx?coll=824a47e1-135f-4508-a5aa-866adcae1111" rel="nofollow">CS106A</a> and using Java 1.6 so tried to get some other peoples code and they too showed the same bug. I tried to draw a simple rect and it works fine.</p> <p>Is it some issue with Java applet as it tends to ignore getWidth() value at all. I used println(); to get getWidth() value and it works.</p> <pre><code> import acm.graphics.GRect; import acm.program.GraphicsProgram; public class Pyramid extends GraphicsProgram { /** * eclipse generated SVUID */ private static final long serialVersionUID = 5703830460071233096L; /** Width of each brick in pixels */ private static final int BRICK_WIDTH = 30; /** Width of each brick in pixels */ private static final int BRICK_HEIGHT = 12; /** Number of bricks in the base of the pyramid */ private static final int BRICKS_IN_BASE = 14; public void run() { //centering the pyramid int _canvasWidth = getWidth(); //canvas width //println(_canvasWidth); //to check if getWidth returns a value int _brickSpace = BRICKS_IN_BASE * BRICK_WIDTH; //space consumed by the base row int _freeSpace = _canvasWidth - _brickSpace; //empty base level space int _xOffset = _freeSpace / 2; //x for left most brick of base row for(int row=0; row&lt;BRICKS_IN_BASE; row++){ //the row number int _rowTab = (BRICK_WIDTH/2) * row; //indentaion for each row int _brickInRow = BRICKS_IN_BASE - row; //bricks as per row for(int _brickNumber=0; _brickNumber&lt;_brickInRow; _brickNumber++){ //placing bricks till _brickInRow int x = (_xOffset + _rowTab) + (_brickNumber * BRICK_WIDTH); int y = (BRICK_HEIGHT * (BRICKS_IN_BASE - row)); //y as per row num GRect _brick = new GRect(x, y, BRICK_WIDTH, BRICK_HEIGHT); //creating brick instance add(_brick); } } } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
