Need help with my code! Trying to do a mousedrag to be able to "draw" in an applet. That part is succesful and works fine(kind of blinks a lot tho), but the button and random color do not work(the line is always black)So why isn't the button showing up in the applet and why wont the random color work?! thank you.
/** * @(#)Text1.java * * * @author * @version 1.00 2011/5/12 */ import java.applet.Applet; import java.awt.*; public class Final2 extends Applet { int[] xCoord,yCoord; int pointCount; public void init() { xCoord = new int[10000]; //first run of program yCoord = new int[10000]; pointCount = 0; add(new Button("Click for random color")); //button for color, regenerates } public boolean action(Event e, Object args) { repaint(); return true; } public void paint(Graphics g) { Expo.setRandomColor(g); for (int k = 0; k < pointCount; k++) g.fillRect(xCoord[k],yCoord[k],2,2); } public boolean mouseDrag(Event e, int x, int y) //mouseDrag method { xCoord[pointCount] = x; yCoord[pointCount] = y; pointCount++; repaint(); return true; } }
