Interface HTMLViewerSpi<HtmlView,HtmlButton>

Type Parameters:

HtmlView - type representing the view as used by this viewer

HtmlButton - type representing buttons as used by this viewer

public interface HTMLViewerSpi<HtmlView,HtmlButton>

Service provider interface for handing display of HTML based user interface. Code using OpenHTMLRegistration, HTMLDialog and HTMLComponent assumes the system to display the HTML page and connect it with the underlaying code - that's a task for this SPI.

Implement this interface and register it using ServiceProvider. When requested (via HTMLViewerSpi.newView(org.netbeans.spi.htmlui.HTMLViewerSpi.Context) method show the HTML page and run the initialization code in the page. There are three possible ways to display an HTML user interface: long lasting window, dialog with extra buttons, a separate HTMLViewerSpi.component(java.lang.Object, java.lang.Class) to embed into existing Swing or JavaFX interface.

Method Detail

newView

HtmlView newView(HTMLViewerSpi.Context context)

Create new HTML view. Based on values of provided context show either:

• window - when HTMLViewerSpi.Context.isWindow() handles OpenHTMLRegistration usages
• dialog - when HTMLViewerSpi.Context.isDialog() handles HTMLDialog usages
• embedable component - when none of above - handles HTMLComponent usages

Parameters:

context - information to display and callbacks to the infrastructure

Returns:

any element representing the view or null if this viewer cannot handle the request

1.23

component

<C> C component(HtmlView view,
                Class<C> type)

Converts the view to a component of the requested type. This method is only called if neither HTMLViewerSpi.Context.isWindow() and HTMLViewerSpi.Context.isDialog() return true. Default implementation supports two values of type: JComponent or Node class - alternative implementations of this interface may not support all these types and may also support other types.

Requesting Void.class means to realize the component - e.g. make it visible.

Type Parameters:

C - the type of requested component

Parameters:

view - element representing the view

type - class of the requested component

Returns:

instance of the component

Throws:

ClassCastException - if the type isn't supported

createButton

HtmlButton createButton(HtmlView view,
                        String id)

Returns:

any element representing the button

getId

String getId(HtmlView view,
             HtmlButton b)

Extracts ID of a button created by HTMLViewerSpi.createButton(java.lang.Object, java.lang.String).

Parameters:

setText

void setText(HtmlView view,
             HtmlButton b,

setEnabled

void setEnabled(HtmlView view,
                HtmlButton b,
                boolean enabled)
