/**
 * This is a window for displaying portlet settings. The window contains a form which in turn will contain the
 * widgets for a portlet's settings. Those widgets will have to be passed to the window since the window is intended
 * to support all portlets. The layout and sizing strategy for this window is to be as large as the widgets contained
 * within it. And the form will stretch and resize as the window is resized. This flexible layout strategy is used
 * since there are different settings (with different widgets) for different portlets which will in turn result in
 * different sizes for the parent window.
