Constructor Summary | |
JDrawingCanvas()
Creates a new DrawingCanvas. |
|
JDrawingCanvas(java.awt.Dimension size)
Creates a new DrawingCanvas. |
|
JDrawingCanvas(int width,
int height)
Creates a new DrawingCanvas. |
Method Summary | |
void |
addToCanvas(Drawable d)
Adds the Drawable d to the JDrawingCanvas |
void |
clear()
Clears the canvas. |
void |
componentHidden(java.awt.event.ComponentEvent e)
Invoked when component has been hidden. |
void |
componentMoved(java.awt.event.ComponentEvent e)
Invoked when component has been moved. |
void |
componentResized(java.awt.event.ComponentEvent e)
Invoked when component has been resized. |
void |
componentShown(java.awt.event.ComponentEvent e)
Invoked when component has been shown. |
void |
disableAutoRepaint()
Turns auto repaint off so the programmer must indicate when the canvas should be repainted. |
void |
enableAutoRepaint()
Turns auto repaint on so the programmer does not have to manually repaint after changing the canvas |
CanvasManager |
getCanvasContent()
Returns an instance of the CanvasContainer |
java.awt.Dimension |
getPreferredSize()
Retrieves the object's preferred size. |
boolean |
imageUpdate(java.awt.Image img,
int infoflags,
int x,
int y,
int width,
int height)
Notifies the CanvasManager of a change in state and calls the native java method imageUpdate. |
void |
paint(java.awt.Graphics g)
Paints the canvas by calling the real paint method of the CanvasManager |
void |
removeFromCanvas(Drawable d)
Removes the Drawable d from the JDrawingCanvas |
void |
update(java.awt.Graphics g)
Updates the screen. |
