Programmatically adding objects/components

Question

Hi guys,
I'm just new to Java and the Java Studio Creator.
Anyway, I would just like to ask how you can programmatically add objects or components after each event, let's ay after every press of a button, another text field, output text, image or whatever component, is added on the page.
I'm trying to do an application wherein the user can enter number of rows they want to show in a table (grid panel) which has by default, 5 columns with one image inside every column. If the user enters 2, the table should now have 2 rows that are identical.
Hope you can help me with this problem guys. Thanks in advance!

Anyway, I would just like to ask how you can
programmatically add objects or components after each
event, let's ay after every press of a button,
another text field, output text, image or whatever
component, is added on the page.The components of a page are organized into a tree structure with parent-child relationships. Therefore, all you need to do is acquire a reference to the component you want to be the parent, create a new instance of the child, and add the new child to the parent component's list of children.
In a page bean, it looks something like this. Assume you want to add a new Output Text component inside the form component named "form1". Because Creator binds all of the components to properties in the page bean, finding this component is easy -- there is an instance variable with the same name that contains a reference to this component. So, you would do something like this:
UIComponent parent = form1; // Get reference to parent
HtmlOutputText newOne = new HtmlOutputText();
newOne.setValue("This is the text value");
// set other properties as needed
parent.getChildren().add(newOne);The value returned by getChildren() is a standard java.util.List, so you can insert children anywhere in the list, remove them, reorganize them, or whatever is needed.
