Constructor Details

Renderer

Renderer(JXLabel c,
 ViewFactory f,
 View v,
 boolean wordWrap)

Method Details

updateLayout

protected void updateLayout(DocumentEvent.ElementChange ec,
 DocumentEvent e,
 Shape a)

Overrides:

updateLayout in class View

preferenceChanged

public void preferenceChanged(View child,
 boolean width,
 boolean height)

Overrides:

preferenceChanged in class BoxView

getAttributes

public AttributeSet getAttributes()

Fetches the attributes to use when rendering. At the root level there are no attributes. If an attribute is resolved up the view hierarchy this is the end of the line.

Overrides:

getAttributes in class View

paint

public void paint(Graphics g,
 Shape allocation)

Renders the view.

Overrides:

paint in class WrappedPlainView

Parameters:

g - the graphics context

allocation - the region to render into

setParent

public void setParent(View parent)

Sets the view parent.

Overrides:

setParent in class CompositeView

Parameters:

parent - the parent view

getViewCount

public int getViewCount()

Returns the number of views in this view. Since this view simply wraps the root of the view hierarchy it has exactly one child.

Overrides:

getViewCount in class CompositeView

Returns:

the number of views

See Also:

• getView(int)

getView

public View getView(int n)

Gets the n-th view in this container.

Overrides:

getView in class CompositeView

Parameters:

n - the number of the view to get

Returns:

the view

getDocument

public Document getDocument()

Returns the document model underlying the view.

Overrides:

getDocument in class View

Returns:

the model

setSize

public void setSize(float width,
 float height)

Sets the view size.

Overrides:

setSize in class WrappedPlainView

Parameters:

width - the width

height - the height

getPreferredSpan

public float getPreferredSpan(int axis)

Overrides:

getPreferredSpan in class WrappedPlainView

getContainer

public Container getContainer()

Fetches the container hosting the view. This is useful for things like scheduling a repaint, finding out the host components font, etc. The default implementation of this is to forward the query to the parent view.

Overrides:

getContainer in class View

Returns:

the container

getViewFactory

public ViewFactory getViewFactory()

Fetches the factory to be used for building the various view fragments that make up the view that represents the model. This is what determines how the model will be represented. This is implemented to fetch the factory provided by the associated EditorKit.

Overrides:

getViewFactory in class View

Returns:

the factory

getWidth

public int getWidth()

Overrides:

getWidth in class BoxView

getHeight

public int getHeight()

Overrides:

getHeight in class BoxView
