How to load dynamic data on a eclipse shell? - eclipse

Question

I want to load details of a user's when clicking their names . So I create a Grid Layout with two columns left hand side is standalone and right hand side data will be loaded based on clicking their names .
JAVA CODE
Display display = PlatformUI.createDisplay();
Shell shell = new Shell(display);
shell.setSize(400, 400);
GridLayout gridLayout = new GridLayout();
gridLayout.numColumns = 2;
shell.setLayout(gridLayout);
shell.setBackground(new Color(display, 255, 255, 255));
final Table table = new Table(shell, SWT.VIRTUAL);
table.setLayout(new GridLayout());
table.setSize(400, 400);
final TableColumn column = new TableColumn(table, SWT.LEFT);
column.setWidth(150);
column.setText("Runnable Services");
table.setItemCount(5);
final String[] services = new String[] { "Franklin", "Christian",
"Richard Levi",
"Dale Steyn", "Chris Gayle" };
table.addListener(SWT.SetData, new Listener() {
public void handleEvent(Event event) {
TableItem item = (TableItem) event.item;
int index = table.indexOf(item);
item.setText(services[index]);
System.out.println(item.getText());
}
});
table.addSelectionListener(new OnClickListener());
alignCenter(shell, display);
shell.open();
I added a selection listener on a table . When click the players I add their details on SelectionListener's widget Selected method .
JAVA CODE
Composite parent = new Composite(table.getParent(), SWT.NONE);
parent.setLayout(new GridLayout(2, false));
Label label = new Label(parent, SWT.NULL);
label.setText("Name :");
System.out.println(table.getSelection()[0].getText());
Text text = new Text(parent, SWT.BORDER);
text.setText(table.getSelection()[0].getText());
text.setLayoutData(new GridData(GridData.FILL_HORIZONTAL
| GridData.GRAB_HORIZONTAL));
ViewActionDelegate.resize(200, true, 20, table.getShell());
If i did like this on click action each time data will be appended to existing shell . How can I clear the righ hand side details ? . I posted a image below .
How can i do this ? .

Answer 1

Finally I found the answer .
Issue :
I append new elements into already created composite .
Solution:
Clear elements from existing composite before drawing new elements .
Java Code :
if ((composite != null) && (!composite.isDisposed())) {
Control[] children = composite2.getChildren();
for(Control ch : children){
ch.dispose();
}
}
