View.java 文件源码

/**
 * Support for creating the view's window.
 * <p>
 * This is called by createShell(Rectangle) in most of our subclasses,
 * but needs to be a static method in each of them, hence we can't use
 * overriding, and instead have this as a helper to be called explicitly.
 *
 * @param bounds if null, use a default position, and otherwise use this as
 *               position and size of the window
 * @param width  if bounds is null, use this as the default width; otherwise
 *               the value of <code>width</code> is ignored
 * @param height if bounds is null, use this as the default height; otherwise
 *               the value of <code>height</code> is ignored
 * @param layout the Layout used by the window
 * @return       the new window
