Loop through components...

Question

hello,
im trying to loop through all the components on a jdialog/jframe ... my end goal is to resize them all, but first im just trying to get the following code working:
   Component[] cmp = this.getRootPane().getComponents();
   for (int x=0; x < cmp.length; x++)
     System.out.println(cmp[x].toString());         
   }i want to get this to display all the components on the frame, but right now it only displays one: JPanel.. i have about 20-40 components on the frame, all in different tabs on a JTabbedPane. anyone know of a nice and easy way to get all the components in an array, or use some type of enumeration to go through all the components on a form?
thanks a lot! talk to ya later,

Answer 1

hey trejkaz/appler,
thanks a lot for the help.. i got it working now. trejkaz, i just wasnt sure what to pass to the method you wrote (i was passing this.getRootPane() and just "this").. but appler's code had this.getContentPane() , so i tried that and it worked ! :)
thanks a lot both of you! anyway, heres the final code i have, in case someone else has the same question later on:
public ArrayList getAllComponents(Container top) {   
    Component[] comp = top.getComponents();       
    ArrayList compList = new ArrayList();
    if (comp.length == 0)       
      return compList;   
    for (int i = 0; i < comp.length; i++) {
        compList.add(comp);
if (comp[i] instanceof Container) {
compList.addAll(getAllComponents((Container)comp[i]));
return compList;
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
// Add your handling code here:
ArrayList compList; // = new ArrayList();
compList = this.getAllComponents(this.getContentPane());
for (int n=0; n < compList.size(); n++)
System.out.println(compList.get(n).toString());
thanks again! talk to ya later,
