Hi,

I am having problems implementing scrollable List. Has any one experienced
same problem.

I am extending standard Dialog functionality for simple selection (as per
documentation).

here is the snippit of code

protected Control createDialogArea(Composite parent) {
Composite composite = (Composite)super.createDialogArea(parent);

list = new List(composite,
SWT.BORDER|SWT.SINGLE|SWT.V_SCROLL|SWT.H_SCROLL);

try{
for (int i = 0; i < 100; i++) {
String listElement = "test String";
list.add(listElement);
}

}catch(CoreException ex){
}

viewer = new ListViewer(list);

return composite;
}

no scrollbars appears!

Did you set the size of the list? Assuming you are using a layout, the list
will be resized such that no scroll bars are necessary. Check out the width
and height hints for layout to set the size.

Thanks Steve,

I want to create simple dialog based list control. Unfortunately the dialog
implementation is supporting scroll feature. (I have tried all possibilities
of setting size, none worked). the work around is instard of using default
dialog initialization (createDialogArea Method) and creaging
ScrolledComposite instand of Composite. Is there any otherway sompler than
that?

Kind Regards,
Guru PRasad

Chances are, the parent for your List has a GridLayout. You can verify this
by calling:

System.out.println(parent.getLayout());

Assuming the parent has a GridLayout, you can fix the height of the List by
setting the GridData.heightHint:

GridData data = new GridData();
data.heightHint = 150;
myList.setLayoutData(data);

See:
