Constructor Detail

JHelpContentViewer

public JHelpContentViewer(HelpSet hs)

Creates a JHelp with an instance of DefaultHelpModel as its data model.

Parameters:

hs - The HelpSet that provides context information. A null hs is valid and creates a TextHelpModel with no HelpSet defined.

JHelpContentViewer

public JHelpContentViewer()

Creates a JHelp with a default TextHelpModel.

JHelpContentViewer

public JHelpContentViewer(TextHelpModel model)

Creates a JHelp with an specific TextHelpModel as its data model.

Parameters:

model - The TextHelpModel. A null model is valid.

Method Detail

setModel

public void setModel(TextHelpModel newModel)

Sets the HelpModel that provides the data. Necessary to convert navigation action into visits...

Parameters:

newModel - The new Model to provide events for this viewer.

getModel

public TextHelpModel getModel()

Returns:

The HelpModel that provides the events.

setUI

public void setUI(HelpContentViewerUI ui)

Sets the HelpViewerUI that provides the current look and feel.

Parameters:

ui - Provides the ComponentUI object. A null ui is valid.

getUI

public HelpContentViewerUI getUI()

Returns:

The HelpViewerUI that provides the current look and feel.

updateUI

public void updateUI()

Replaces the UI with the latest version from the default UIFactory.

Overrides:

updateUI in class javax.swing.JComponent

getUIClassID

public java.lang.String getUIClassID()

Overrides:

getUIClassID in class javax.swing.JComponent

Returns:

"HelpViewerUI"

setCurrentID

public void setCurrentID(Map.ID id)
                  throws InvalidHelpSetContextException

Visits a given ID. Propagates down into the model.

Parameters:

id - The ID to visit.

Throws:

InvalidHelpSetContextException - if id.hs is not contained in the HelpSet of the current model.

setCurrentID

public void setCurrentID(java.lang.String id)
                  throws BadIDException

Visits a given ID. Propagates down into the model.

Parameters:

id - The String to visit. Relative to the HS of the current model.

Throws:

BadIDException - The ID is not valid for the HelpSet for the current model.

setCurrentURL

public void setCurrentURL(java.net.URL url)

Visits a given URL. Propagates down into the model.

Parameters:

url - The URL to visit. Relative to the HS of the current model

getCurrentURL

public java.net.URL getCurrentURL()

Returns:

The URL currently being presented in the viewer.

getDocumentTitle

public java.lang.String getDocumentTitle()

Returns:

The document title.

addHighlight

public void addHighlight(int p0,
                         int p1)

getSynch

public boolean getSynch()

Returns synchronization mode

createEditorKitForContentType

public javax.swing.text.EditorKit createEditorKitForContentType(java.lang.String type)

Creates a handler for the given type from the registry of editor kits. If the registered class has not yet been loaded, an attempt is made to dynamically load the prototype of the kit for the given type. If the type was registered with a ClassLoader, that ClassLoader is used to load the prototype. If there was no registered ClassLoader, the ClassLoader for the HelpSet is used to load the prototype.

Once a prototype EditorKit instance is successfully located, it is cloned and the clone is returned.

Parameters:

type - the content type

Returns:

the editor kit, or null if one cannot be created
