java.lang.Object
  javax.swing.text.View
      javax.swing.plaf.basic.BasicHTML.HTMLRootView

All Implemented Interfaces:

javax.swing.SwingConstants

Enclosing class:

BasicHTML

---

private static class BasicHTML.HTMLRootView

extends javax.swing.text.View

This class serves as the root view for HTML rendering components. Its purpose and implementation is similar to the BasicTextUI.RootView class, only that is implements some stuff differently due to the nature of not beeing inside a JTextComponent.

---

Field Summary
private  javax.swing.JComponent	component           The component on which to render the view.
private  javax.swing.text.Document	document           The document to use.
private  javax.swing.text.EditorKit	editorKit           The EditorKit.
private  javax.swing.text.View	view           The real root view.

Field Detail

view

private javax.swing.text.View view

The real root view.

---

component

private javax.swing.JComponent component

The component on which to render the view.

---

editorKit

private javax.swing.text.EditorKit editorKit

The EditorKit.

---

document

private javax.swing.text.Document document

The document to use.

Constructor Detail

BasicHTML.HTMLRootView

public BasicHTML.HTMLRootView(javax.swing.JComponent c,
                              javax.swing.text.View view,
                              javax.swing.text.EditorKit kit,
                              javax.swing.text.Document doc)

Creates a new RootView.

Method Detail

getViewFactory

public javax.swing.text.ViewFactory getViewFactory()

Returns the ViewFactory for this RootView. If the current EditorKit provides a ViewFactory, this is used. Otherwise the TextUI itself is returned as a ViewFactory.

---

preferenceChanged

public void preferenceChanged(javax.swing.text.View v,
                              boolean width,
                              boolean height)

Indicates that the preferences of one of the child view has changed. This calls revalidate on the text component.

---

setView

public void setView(javax.swing.text.View v)

Sets the real root view.

---

getView

public javax.swing.text.View getView(int index)

Returns the real root view, regardless of the index.

---

getViewCount

public int getViewCount()

Returns 1 since the RootView always contains one child, that is the real root of the View hierarchy.

---

getContainer

public java.awt.Container getContainer()

Returns the Container that contains this view. This normally will be the text component that is managed by this TextUI.

---

getPreferredSpan

public float getPreferredSpan(int axis)

Returns the preferred span along the specified axis. This is delegated to the real root view.

---

paint

public void paint(java.awt.Graphics g,
                  java.awt.Shape s)

Paints the view. This is delegated to the real root view.

---

modelToView

public java.awt.Shape modelToView(int position,
                                  java.awt.Shape a,
                                  javax.swing.text.Position.Bias bias)
                           throws javax.swing.text.BadLocationException

Maps a position in the document into the coordinate space of the View. The output rectangle usually reflects the font height but has a width of zero. This is delegated to the real root view.

---

viewToModel

public int viewToModel(float x,
                       float y,
                       java.awt.Shape a,
                       javax.swing.text.Position.Bias[] b)

Maps coordinates from the View's space into a position in the document model.

---

insertUpdate

public void insertUpdate(javax.swing.event.DocumentEvent ev,
                         java.awt.Shape shape,
                         javax.swing.text.ViewFactory vf)

Notification about text insertions. These are forwarded to the real root view.

---

removeUpdate

public void removeUpdate(javax.swing.event.DocumentEvent ev,
                         java.awt.Shape shape,
                         javax.swing.text.ViewFactory vf)

Notification about text removals. These are forwarded to the real root view.

---

changedUpdate

public void changedUpdate(javax.swing.event.DocumentEvent ev,
                          java.awt.Shape shape,
                          javax.swing.text.ViewFactory vf)

Notification about text changes. These are forwarded to the real root view.

---

getNextVisualPositionFrom

public int getNextVisualPositionFrom(int pos,
                                     javax.swing.text.Position.Bias b,
                                     java.awt.Shape a,
                                     int d,
                                     javax.swing.text.Position.Bias[] biasRet)
                              throws javax.swing.text.BadLocationException

Returns the document position that is (visually) nearest to the given document position pos in the given direction d.

---
