This is the view associated with the html tag NOFRAMES. This view has been written to ignore the contents of the NOFRAMES tag. The contents of the tag will only be visible when the JTextComponent the view is contained in is editable.

Constructor:
public NoFramesView(Element elem, int axis) { super(elem, axis); visible = false; } Creates a new view that represents an html box. This can be used for a number of elements. By default this view is not visible. Parameters: `elem` - the element to create a view for `axis` - either View.X_AXIS or View.Y_AXIS

Method from javax.swing.text.html.NoFramesView Detail:
public float getMaximumSpan(int axis) { if (!visible) { return 0; } return super.getMaximumSpan(axis); } Determines the maximum span for this view along an axis. Returns 0 if the view is not visible, otherwise it calls the superclass method ot get the maximum span.
public float getMinimumSpan(int axis) { if (!visible) { return 0; } return super.getMinimumSpan(axis); } Determines the minimum span for this view along an axis. Returns 0 if the view is not visible, otherwise it calls the superclass method to get the minimum span.
public float getPreferredSpan(int axis) { if (!visible) { return 0; } return super.getPreferredSpan(axis); } Determines the preferred span for this view. Returns 0 if the view is not visible, otherwise it calls the superclass method to get the preferred span. axis.
public boolean isVisible() { return visible; } Returns a true/false value that represents whether the view is visible or not.
protected void layout(int width, int height) { if (!isVisible()) { return; } super.layout(width, height); } Do nothing if the view is not visible, otherwise invoke the superclass to perform layout.
public void paint(Graphics g, Shape allocation) { Container host = getContainer(); if (host != null && visible != ((JTextComponent)host).isEditable()) { visible = ((JTextComponent)host).isEditable(); } if (!isVisible()) { return; } super.paint(g, allocation); } If this view is not visible, then it returns. Otherwise it invokes the superclass.
public void setParent(View p) { if (p != null) { Container host = p.getContainer(); if (host != null) { visible = ((JTextComponent)host).isEditable(); } } super.setParent(p); } Determines if the JTextComponent that the view is contained in is editable. If so, then this view and all its child views are visible. Once this has been determined, the superclass is invoked to continue processing.
