java - get access to each dynamically added jComponent -

before asked question , value dynamically added jtextfields , jcomboboxes using answer question.

now in subpanel have 3 jcomboboxes , 4 jtextfields.

to value of jcomponent using code:

component[] children = jpanel1.getcomponents(); // iterate on subpanels... (component sp : children) {     if (sp instanceof subpanel) {         component[] spchildren = ((subpanel)sp).getcomponents();         // iterate on jtextfields...         (component spchild : spchildren) {             if (spchild instanceof jtextfield) {                 string text = ((jtextfield)spchild).gettext();                 system.out.println(text);             }         }     } } 

i ask possible access each jcomboboxes , jtextfields separately, i.e. can manipulate each jcomponent , set them different values? how can achieve this?

thank in advance.

rather traversing component hierarchy (which fragile layout changes), can keep references components. following example class contains instance variables child components:

public class componentwrapper extends jcomponent{      private jcombobox combo;     private jtextarea textarea;      public componentwrapper(){         combo = new jcombobox();         textarea = new jtextarea();         add(combo);         add(textarea);     }      public text gettextarea(){         return textarea;     }      public jcombobox getcombobox(){         return combobox;     } } 

the above class extends jcomponent, adds components within constructor, , can added container elsewhere. note above class example how this, , may need further adapted depending upon requirements. usage:

componentwrapper wrapper = new componentwrapper (); add(wrapper); revalidate();//if adding 'dynamically'  //later, when want text string text = wrapper.gettextarea().gettext();
