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!

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);
