Hey, Im having a problem getting my applet to repaint after it is resized. + and - buttons resize it but sometimes it wont get bigger or repaint.
here is the src for the applet
private ArrayList<CompareColor> myColors;
private ArrayList<CompareColor> fixedColors;
private int w=0;
private int h=0;
private int csize = 10;
int dots = 10;
public void init() {
myColors = new ArrayList<CompareColor>();
fixedColors = new ArrayList<CompareColor>();
//initialize ArrayList
int r = 0;
int g = 0;
int b = 0;
for (int i = 0; i < dots; i++) {
// use the Math.random() methos to generate a random int [0, 256);
r = Math.round((float) Math.random() * 255);
g = Math.round((float) Math.random() * 255);
b = Math.round((float) Math.random() * 255);
//add CompareColor object to ArrayList
myColors.add(new CompareColor(r, g, b));
fixedColors.add(new CompareColor(r, g, b));
}
Collections.sort(fixedColors);
}
public void changeSize(int c) {
csize += c;
if(csize<0)csize=0;
w=dots * (csize * 4) + 15;
h=csize * 8;
this.setSize(w,h );
this.repaint();
}
public int getDefaultWidth() {
return w;
}
public int getDefaultHeight() {
return h;
}
public void paint(Graphics g) {
super.paint(g);
Graphics2D g2 = (Graphics2D) g;
this.setSize(dots * (csize * 4) + 15, csize * 8);
for (int i = 0; i < 10; i++) {
g2.setColor(myColors.get(i));
g2.fillOval(csize + (i * csize * 4), csize, csize * 2, csize * 2);
g2.drawString(myColors.get(i).getBlue() + " ", csize + (i * csize * 4) + csize, csize);
}
for (int i = 0; i < 10; i++) {
g2.setColor(fixedColors.get(i));
g2.fillOval(csize + (i * csize * 4), csize * 4 + 10, csize * 2, csize * 2);
g2.drawString(fixedColors.get(i).getBlue() + " ", csize + (i * csize * 4) + csize, csize * 4 + 10);
}
}and here is the html
<HTML>
<HEAD>
<TITLE>Sort Colors</TITLE>
</HEAD>
<BODY >
<APPLET codebase="classes" code="sortcolors/SortColorsTest.class" width=415 height=80 mayscript="true" name="appl"></APPLET><br />
<input type="button" onClick="cs(1)" value="+"> <input type="button" onClick="cs(-1)" value="-">
</P>
</BODY>
</HTML>
<script type="text/javascript">
function fixWidth(){
document.appl.width=document.appl.getDefaultWidth();
document.appl.height=document.appl.getDefaultHeight();
}
function cs(x){
document.appl.changeSize(x);
fixWidth();
}
</script>ive tried repainting it at different places but nothing seems to work. It doesnt always happen, only sometimes when resizing.
Attached the build
Thanks
