    <p>I'm working on some exercises and I've been stuck on this for some hours now (quite new to Java). Anyhow, this is what I'm supposed to do: When I run the program I will have a square in the middle of the screen and when I then click somewhere within that screen another square will be drawn at the place where I clicked and in-between these two points there are supposed to be 10 squares. So wherever I click there should always be 10 squares drawn between.</p> <p>However, I can't make it to function properly.</p> <p>This is what I've managed to do so far:</p> <pre><code>import se.lth.cs.ptdc.window.SimpleWindow; import se.lth.cs.ptdc.square.Square; public class PrintSquares2 { public static void main(String[] args) { SimpleWindow w = new SimpleWindow(600, 600, "PrintSquares2"); int posX = 300; int posY = 300; int loop = 0; System.out.println("Skriv rotation"); Square sq1 = new Square(posX,posY,200); sq1.draw(w); w.waitForMouseClick(); int destX = w.getMouseX(); int destY = w.getMouseY(); System.out.println("Dest X: " + destX + " Dest Y: " + destY); System.out.println("Pos X: " + posX + " Pos Y: " + posY); SimpleWindow.delay(10); //sq1.erase(w); int jumpX = (destX - posX) / 10; int jumpY = (destY - posY) / 10; System.out.println(jumpX); while (posX &lt; destX) { posX = posX+10; SimpleWindow.delay(100); loop++; System.out.println("Loop: " + loop); System.out.println("Dest X: " + destX + " Dest Y: " + destY); System.out.println("Pos X: " + posX + " Pos Y: " + posY); Square sq2 = new Square(posX,posY,200); sq2.draw(w); } while (posX &gt; destX) { posX = posX-10; SimpleWindow.delay(100); loop++; System.out.println("Loop: " + loop); System.out.println("Dest X: " + destX + " Dest Y: " + destY); System.out.println("Pos X: " + posX + " Pos Y: " + posY); sq1.draw(w); Square sq2 = new Square(posX,posY,200); sq2.draw(w); } while (posY &lt; destY) { posY = posY+10; SimpleWindow.delay(100); loop++; System.out.println("Loop: " + loop); System.out.println("Dest X: " + destX + " Dest Y: " + destY); System.out.println("Pos X: " + posX + " Pos Y: " + posY); sq1.draw(w); Square sq2 = new Square(posX,posY,200); sq2.draw(w); } while (posY &gt; destY) { posY = posY-10; SimpleWindow.delay(100); loop++; System.out.println("Loop: " + loop); System.out.println("Dest X: " + destX + " Dest Y: " + destY); System.out.println("Pos X: " + posX + " Pos Y: " + posY); sq1.draw(w); Square sq2 = new Square(posX,posY,200); sq2.draw(w); } SimpleWindow.delay(10); sq1.draw(w); //SimpleWindow.clear(w); } </code></pre> <p>}</p> <p>I'm pretty sure that I overcomplicated everything since this should be pretty basic.</p> <p>The end result is supposed to look like this: <a href="http://i.stack.imgur.com/ZxUM2.png" rel="nofollow">End result</a></p>

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.
