  Fetch a Graphics for rendering.
public float getMaximumSpan (int axis) [Overrides View]
  Determines the maximum span for this view along an axis.
public float getMinimumSpan (int axis) [Overrides View]
  Determines the minimum span for this view along an axis.
public int getNextVisualPositionFrom (int pos, Bias b, Shape a, int direction, Bias biasRet) throws BadLocationException [Inherited From View]
  Provides a way to determine the next visually represented model location at which one might place a caret.
public View getParent () [Inherited From View]
  Returns the parent of the view.
public float getPreferredSpan (int axis) [Specified in View]
  Determines the preferred span for this view along an axis.
public int getResizeWeight (int axis) [Inherited From View]
  Determines the resizability of the view along the given axis.
public int getStartOffset () [Inherited From View]
  Fetches the portion of the model for which this view is responsible.
public String getToolTipText (float x, float y, Shape allocation) [Inherited From View]
  Returns the tooltip text at the specified location.
public View getView (int n) [Inherited From View]
  Gets the nth child view.
public int getViewCount () [Inherited From View]
  Returns the number of views in this view.
public ViewFactory getViewFactory () [Inherited From View]
  Fetches the ViewFactory implementation that is feeding the view hierarchy.
public int getViewIndex (float x, float y, Shape allocation) [Inherited From View]
  Returns the child view index representing the given position in the view.
public int getViewIndex (int pos, Bias b) [Inherited From View]
  Returns the child view index representing the given position in the model.
public void insert (int offs, View v) [Inherited From View]
  Inserts a single child view.
public void insertUpdate (DocumentEvent e, Shape a, ViewFactory f) [Inherited From View]
  Gives notification that something was inserted into the document in a location that this view is responsible for.
public boolean isVisible () [Inherited From View]
  Returns a boolean that indicates whether the view is visible or not.
public Shape modelToView (int p0, Bias b0, int p1, Bias b1, Shape a) throws BadLocationException [Inherited From View]
  Provides a mapping, for a given region, from the document model coordinate space to the view coordinate space.
@Deprecated
public Shape modelToView (int pos, Shape a) throws BadLocationException [Inherited From View]
  Provides a mapping from the document model coordinate space to the coordinate space of the view mapped to it.
public Shape modelToView (int pos, Shape a, Bias b) throws BadLocationException [Specified in View]
  Provides a mapping from the coordinate space of the model to that of the view.
public void paint (Graphics g, Shape a) [Specified in View]
  The real paint behavior occurs naturally from the association that the component has with its parent container (the same container hosting this view).
public void preferenceChanged (View child, boolean width, boolean height) [Inherited From View]
  Child views can call this on the parent to indicate that the preference has changed and should be reconsidered for layout.
public void remove (int i) [Inherited From View]
  Removes one of the children at the given position.
public void removeAll () [Inherited From View]
  Removes all of the children.
public void removeUpdate (DocumentEvent e, Shape a, ViewFactory f) [Inherited From View]
  Gives notification that something was removed from the document in a location that this view is responsible for.
public void replace (int offset, int length, View views) [Inherited From View]
  Replaces child views.
pack-private void setComponentParent ()
Set the parent of the embedded component with assurance that it is thread-safe.
public void setParent (View p) [Overrides View]
  Sets the parent for a child view.
public void setSize (float width, float height) [Inherited From View]
  Sets the size of the view.
protected boolean updateChildren (ElementChange ec, DocumentEvent e, ViewFactory f) [Inherited From View]
  Updates the child views in response to receiving notification that the model changed, and there is change record for the element this view is responsible for.
protected void updateLayout (ElementChange ec, DocumentEvent e, Shape a) [Inherited From View]

  The weight to indicate a view supports breaking, and must be broken to be represented properly when placed in a view that formats its children by breaking them.
publicfinalstatic int GoodBreakWeight = "1000" [Inherited From View]
