java how to get top level container of a compoent?

Question

is there a way to get the top level container of a component? For example I have a JToolbar and I want to know at one monent the top level container of that JToolbar is my JFrame or is its own window, a JDialog.

Answer 1

If the component has been added to the hierarchy, you can look up the top-level container by recursively calling getParent:

Container c = toolbar;
while ( c.getParent() != null )
{
  c = c.getParent();
}

if ( c instanceof JFrame )
{
  //...
}

Answer 2

SwingUtilities.windowForComponent(...);
