0N/A * The views produced for the ComponentUI implementations aren't 0N/A * going to be edited and don't need full html support. This kit 0N/A * alters the HTMLEditorKit to try and trim things down a bit. 0N/A * It does the following: 0N/A * <li>It doesn't produce Views for things like comments, 0N/A * head, title, unknown tags, etc. 0N/A * <li>It installs a different set of css settings from the default 0N/A * provided by HTMLEditorKit. 0N/A /** Shared base style for all documents created by us use. */ 0N/A * Overriden to return our own slimmed down style sheet. 0N/A // don't want to die in static initialization... 0N/A // just display things wrong. 0N/A * Sets the async policy to flush everything in one chunk, and 0N/A * to not display unknown tags. 0N/A * Returns the ViewFactory that is used to make sure the Views don't 0N/A * load in the background. 0N/A * BasicHTMLViewFactory extends HTMLFactory to force images to be loaded 0N/A * The subclass of HTMLDocument that is used as the model. getForeground 0N/A * is overridden to return the foreground property from the Component this 0N/A /** The host, that is where we are rendering. */ 0N/A // private JComponent host; 0N/A * Sets the default font and default color. These are set by 0N/A * adding a rule for the body that specifies the font and color. 0N/A * This allows the html to override these should it wish to have 0N/A * a custom font or color. 0N/A * Root text view that acts as an HTML renderer. 0N/A // initially layout to the preferred size 0N/A * Fetches the attributes to use when rendering. At the root 0N/A * level there are no attributes. If an attribute is resolved 0N/A * up the view hierarchy this is the end of the line. 0N/A * Determines the preferred span for this view along an axis. 0N/A * @param axis may be either X_AXIS or Y_AXIS 0N/A * @return the span the view would like to be rendered into. 0N/A * Typically the view is told to render into the span 0N/A * that is returned, although there is no guarantee. 0N/A * The parent may choose to resize or break the view. 0N/A // width currently laid out to 0N/A * Determines the minimum span for this view along an axis. 0N/A * @param axis may be either X_AXIS or Y_AXIS 0N/A * @return the span the view would like to be rendered into. 0N/A * Typically the view is told to render into the span 0N/A * that is returned, although there is no guarantee. 0N/A * The parent may choose to resize or break the view. 0N/A * Determines the maximum span for this view along an axis. 0N/A * @param axis may be either X_AXIS or Y_AXIS 0N/A * @return the span the view would like to be rendered into. 0N/A * Typically the view is told to render into the span 0N/A * that is returned, although there is no guarantee. 0N/A * The parent may choose to resize or break the view. 0N/A * Specifies that a preference has changed. 0N/A * Child views can call this on the parent to indicate that 0N/A * the preference has changed. The root view routes this to 0N/A * invalidate on the hosting component. 0N/A * This can be called on a different thread from the 0N/A * event dispatching thread and is basically unsafe to 0N/A * propagate into the component. To make this safe, 0N/A * the operation is transferred over to the event dispatching 0N/A * thread for completion. It is a design goal that all view 0N/A * methods be safe to call without concern for concurrency, 0N/A * and this behavior helps make that true. 0N/A * @param child the child view 0N/A * @param width true if the width preference has changed 0N/A * @param height true if the height preference has changed 0N/A * Determines the desired alignment for this view along an axis. 0N/A * @param axis may be either X_AXIS or Y_AXIS 0N/A * @return the desired alignment, where 0.0 indicates the origin 0N/A * and 1.0 the full span away from the origin 0N/A * @param g the graphics context 0N/A * @param allocation the region to render into 0N/A * Sets the view parent. 0N/A * @param parent the parent view 0N/A throw new Error(
