Constructor Detail

JDrawing

public JDrawing()
Returns a JDrawing with an empty model.

See Also:
DefaultDrawingModel

JDrawing

public JDrawing(DrawingModel model)
Returns an instance of JDrawing which displays the specified model.

Method Detail

setModel

public void setModel(DrawingModel model)
Sets the DrawingModel that will provide the data.

Parameters:
model - the DrawingModel that is to provide the data

getModel

public DrawingModel getModel()
Returns the DrawingModel that is providing the data.

Returns:
the DrawingModel that is providing the data

setModelCache

public void setModelCache(DrawingModelCache cache)
Sets the DrawingModelCache that will optimize redrawing.

Parameters:
cache - the DrawingModelCache that is to optimize redrawing

getModelCache

public DrawingModelCache getModelCache()
Returns the DrawingModelCache that is optimizing redrawing.

Returns:
the DrawingModelCache that is optimizing redrawing

setElementRenderer

public void setElementRenderer(DrawingElementRenderer renderer)
Sets the DrawingElementRenderer that will be used to draw each element.

Parameters:
renderer - the DrawingElementRenderer that is to render each element

getElementRenderer

public DrawingElementRenderer getElementRenderer()
Returns the current DrawingElementRenderer that is rendering each element. By default JDrawing installs renderer, which can render instances of Shape, Component, DrawingElement and CompoundDrawingElement classes.

Returns:
the DrawingElementRenderer that is rendering each element

setOrigin

public void setOrigin(java.awt.Point origin)
Sets the coordination of origin point of the drawing in to client coordinate space.

Parameters:
origin - new coordinates of the origin point

getOrigin

public java.awt.Point getOrigin()
Returnss the coordination of origin point of the drawing in to client coordinate space.

Returns:
coordinates of the origin point

areaChanged

public void areaChanged(DrawingModelCacheEvent event)
Invoked after some area of the drawing has changed in some way. Repaints changed area.

Specified by:
areaChanged in interface DrawingModelCacheListener
Parameters:
event - DrawingModelCacheEvent object encapsulating event information

drawingChanged

public void drawingChanged(DrawingModelCacheEvent event)
Invoked after the drawing has changed in some way. Repaints component.

Specified by:
drawingChanged in interface DrawingModelCacheListener
Parameters:
event - DrawingModelCacheEvent object encapsulating event information

paintComponent

protected void paintComponent(java.awt.Graphics graphics)
Paints this JDrawing component. Uses backgroundColor to fill the area to be painted, and then paints all neccessary elements using current DrawingElementRenderer
