public abstract class AnnotationComponentFactory
extends ViewerFeature

A type of ViewerFeature that creates a JComponent to represent a PDFAnnotation on the page. Typically AnnotationComponentFactories are singleton objects, as they do not need to be tied to a specific viewer. For viewing components, all that needs to be overridden are the matches() and createComponent() methods. If you want to use this factory to edit and/or create new annotations, it's necessary to override the createEditComponent(), getAnnotationType() and createNewAnnotation() methods as well.

Constructor Detail

AnnotationComponentFactory

public AnnotationComponentFactory(String name)

Create a new AnnotationComponentFactory

Parameters:

name - the name of this ViewerFeature

Method Detail

toString

public String toString()

Overrides:

toString in class ViewerFeature

matches

public abstract boolean matches(PDFAnnotation annot)

Return true if this AnnotationComponentFactory could create a JComponent for the specified PDFAnnotation.

createComponent

public abstract JComponent createComponent(PagePanel pagepanel,
                                           PDFAnnotation annot)

Return a JComponent that will visually represent the specified PDFAnnotation.

Parameters:

pagepanel - the panel the JComponent will be added to

annot - the annotation

createEditComponent

public JComponent createEditComponent(PDFAnnotation annot,
                                      boolean readonly,
                                      boolean create)

Return a JComponent that can be used to edit the annotation or display additional information. If the annotation has no dialog that should work with it in this way, this method should return null (the default)

Parameters:

annot - the annotation

readonly - whether we are displaying or editing the annotation

create - if readonly if false, whether we are editing an existing or creating a new annotation

2.10

getAnnotationType

public String getAnnotationType()

Return the name of the type of widgets this AnnotationComponentFactory creates or edits.

Since:

2.10

createNewAnnotation

public PDFAnnotation createNewAnnotation()

Return a brand new annotation of the type that is edited with this factory. If this factory cannot be used to create a new annotation, this method can return null (the default)

paintComponent

protected static final void paintComponent(JComponent comp,
                                           String state,
                                           Graphics g)

This method can be called by the paintComponent method of each JComponent returned from an AnnotationComponentFactory to repaint the annotation using the content of the annotation.

Parameters:

comp - the component

state - the state to paint. Typically this will be "N"

g - the Graphics object

bindComponentLocation

public static final void bindComponentLocation(JComponent component,
                                               float[] rect)

Cause the specified JComponent to be positioned at the PDF co-ordinates specified by rect. If the page is scrolled or zoomed the component will be zoomed and resized to match.

Parameters:

component - the Component

rect - the component location in PDF space, specified as [x1, y1, x2, y2]

bindComponentLocation

public static final void bindComponentLocation(JComponent component,
                                               float x1,
                                               float y1,
                                               float x2,
                                               float y2)

Cause the specified JComponent to be positioned at the specified PDF co-ordinates. If the page is scrolled or zoomed the component will be zoomed and resized to match.

Parameters:

component - the Component

x1 - the left-most X co-ordinate of the component in PDF space

y1 - the bottom-most Y co-ordinate of the component in PDF space

x2 - the right-most X co-ordinate of the component in PDF space

y2 - the top-most Y co-ordinate of the component in PDF space

bindComponentLocation

public static final void bindComponentLocation(JComponent component,
                                               PDFAnnotation annot)

Cause the specified JComponent to be positioned at same position as the PDFAnnotation. If the page is scrolled or zoomed the component will be zoomed and resized to match.

Parameters:
