```
    When this method returns true, the HstComponentWindow is still part of the hierarchy of HstComponentWindows, but the doBeforeRender of the getComponent() and dispatched from the HstResponse will be skipped.
    Returns: true when this HstComponentWindow should be visible, false otherwise
  setVisible void setVisible(boolean visible) Parameters: visible - sets whether this HstComponentWindow is visible or not. Setting this HstComponentWindow visibility to false, automatically sets all descendant HstComponentWindows visibility to false as well removeChildWindow void removeChildWindow(HstComponentWindow window) removes the window from the child windows if exists and otherwise does nothing Parameters: window - the window to remove
