| DisplayCanvas | | public class DisplayCanvas extends Canvas implements ErrorReporter,InputObject,Computable(Code) | | A DisplayCanvas is a drawing area that can contain one or more CoordinateRects.
Each CoordinateRect can, in turn, contain Drawable items. If you only want
one CoordinateRect that fills the whole canvas, you can for the most part
ignore the CoordinateRect and work only with the canvas.
The option of using an offscreen image for double buffering is provided.
By default, this option is on.
If a DisplayCanvas is added to a
Controller, then it will take care of calling the checkInput()
and compute() methods of the InputObjects and Computables that
it contains, so there is no need to add them individually to
the Controller. If the DisplayCanvas is added to a JCMPanel, it
is automatically added to the Controller for that JCMPanel.
(On the other hand, if a DisplayCanvas is added to a Controller,
this means that all the
items in the DisplayCanvas will be recomputed, even if only some
of them need to be.)
The canvas can display an error message that goes away
when the canvas is clicked or when clearErrorMessage()
is called. This allows the Canvas to be used as an
ErrorReporter for a Controller or LimitControlPanel.
When any changes are made to the contents of the Canvas,
doRedraw() must be called for those changes to take effect.
Normally, doRedraw() is called by the CoordinateRect or by
one of the Drawables in a CoordinateRect. Use doRedraw(CoordinateRect c)
or doRedraw(int index) to redraw a single CoordinateRect. Note that
repainting the canvas is not enough, because this will not automatically
refresh the off-screen image.

|
| checkInput | | public synchronized void checkInput()(Code) | | This is generally called by a Controller. It calls the checkInput() method of
any InputObject displayed on this Canvas.
|
| clearErrorMessage | | public synchronized void clearErrorMessage()(Code) | | Clear the error message, if any, that is currently displayed on the canvas.
|
| compute | | public synchronized void compute()(Code) | | This is generally called by a Controller. It calls the compute() method of
any InputObject displayed on this Canvas.
|
| doRedraw | | public synchronized void doRedraw()(Code) | | Should be called whenever the contents of the canvas have changed and so
it needs to need to be redrawn. (This causes the off-screen image to be redrawn.
A simple call to repaint() does not do this.)
If only one CoordinateRect needs to be repainted, you can call doRedraw(int i) or
or doRedraw(CoordinateRect c), which can be more efficient than redrawing the whole canvas.
If an error message is displayed, it will be cleared.
|
| doRedraw | | public synchronized void doRedraw(int coordRectIndex)(Code) | | To be called when the contents of one of the CordinateRects have changed and so
it needs to need to be redrawn. (This causes the off-screen image to be redrawn.
A simple call to repaint() does not do this.)
If an error message is displayed, it will be cleared.
Parameters:
coordRectIndex - The index of the CoordinateRect to be redrawn, where the first CoordinateRect is at index zero.If there is no such CoordinateRect, then nothing is done. |
| doRedraw | | public synchronized void doRedraw(CoordinateRect coords)(Code) | | To be called when the contents of one of the CordinateRects have changed and so
it needs to need to be redrawn. (This causes the off-screen image to be redrawn.
A simple call to repaint() does not do this.)
If an error message is displayed, it will be cleared.
Parameters:
coords - The CoordinateRect to be redrawn. If coords is not in this DisplayCanvas, nothing is done. |
| drawTemp | | public void drawTemp(DrawTemp drawItem)(Code) | | Draws the specified item in the first CoordinateRect in this canvas.
It is drawn on screen and on the off-screen canvas, if there is one.
However, no information is kept about this item, so the drawing will
disappear the next time the off-screen canvas is re-drawn (if there
is an off-screen canvas) or the next time the canvas is repainted
(is there is no off-screen canvas). If the canvas contains no
CoordinateRect when this is called, a new one is added. Note that
this method should only be called after the canvas has appeared on
the screen.
|
| drawTemp | | public synchronized void drawTemp(DrawTemp drawItem, int coordRectIndex)(Code) | | Draws the specified item in the specified CoordinateRect in this canvas.
It is drawn on screen and on the off-screen canvas, if there is one.
However, no information is kept about this item, so the drawing will
disappear the next time the off-screen canvas is re-drawn (if there
is an off-screen canvas) or the next time the canvas is repainted
(is there is no off-screen canvas). Note that
this method should only be called after the canvas has appeared on
the screen.
Parameters:
drawItem - The non-null object that is to be drawn
Parameters:
coordRectIndex - The index of the CoordinateRect in which it is to be drawn, where the index of the fist CoordinateRectadded to the canvas is zero, and so on. If there isno CoordinateRect with the specified index, an IllegalArgumentExceptionis thrown. |
| findCoordinateRectAt | | public CoordinateRect findCoordinateRectAt(int pixelX, int pixelY)(Code) | | Return CoordinateRect that contains the specified pixel, or
null if there is none. The CoordinateRects are searched in
reverse order, so that the "top" CoordinateRect at that point is
returned. Note that this method only makes sense if the canvas
has already been displayed.
(Mostly, this is for internal use in this class.)
|
| getCoordinateRect | | public CoordinateRect getCoordinateRect()(Code) | | Get the first CoordinateRect in this canvas. (If none exists, one is created and
added to the canvas.)
|
| getCoordinateRect | | public CoordinateRect getCoordinateRect(int i)(Code) | | Get the i-th CoordinateRect in this DisplayCanvas. They are numbered staring from zero.
If there is no i-th rect, null is returned, except that if there
are NO coordinate rects and a request for rect 0 is received,
then a new CoordinateRect is added to fill the entire canvas.
|
| getErrorBackground | | public Color getErrorBackground()(Code) | | Get color that is used as a background when the canvas displays an error message.
|
| getErrorForeground | | public Color getErrorForeground()(Code) | | Get color that is used for the text when the canvas displays an error message.
|
| getErrorMessage | | public synchronized String getErrorMessage()(Code) | | Get the error message that is currently displayed on the canvas. If no error
is displyed, the return value is null.
|
| getHandleMouseZooms | | public boolean getHandleMouseZooms()(Code) | | Get the "handleMouseZooms" property of this DisplayCanvas, which determines whether the
canvas reacts to mouse events by zooming the CoordinateRect that is clicked.
|
| getPreferredSize | | public Dimension getPreferredSize()(Code) | | This has been overridden to return a default size of 350-by-350 pixels.
Not usually called directly.
|
| getUseOffscreenCanvas | | public boolean getUseOffscreenCanvas()(Code) | | Set the "useOffscreenCanvas" property of this DisplayCanvas. IF the value is true,
an off-screen image is used for double buffering. This property is true by default.
|
| notifyControllerOnChange | | public void notifyControllerOnChange(Controller c)(Code) | | Method required by InputObject interface; in this class, calls the same method
recursively on any CoordinateRects contained in this DisplayCanvas. This is meant to
be called by JCMPanel.gatherInputs().
|
| paint | | public synchronized void paint(Graphics g)(Code) | | Draw the contents of the DisplayCanvas.
Not usually called directly.
|
| processMouseEvent | | public void processMouseEvent(MouseEvent evt)(Code) | | This has been overridden to handle the mouse zoom feature.
Not meant to be called directly.
|
| processMouseMotionEvent | | public void processMouseMotionEvent(MouseEvent evt)(Code) | | This has been overridden to handle the mouse zoom feature.
Not meant to be called directly.
|
| releaseResources | | public void releaseResources()(Code) | | Release the memory used the by the off-screen image, if any, that is used for
double-buffering. It's a good idea to call this if the DisplayCanvas is in
an applet and the applet is stopped.
|
| setErrorBackground | | public void setErrorBackground(Color c)(Code) | | Set color to be used as a background when the canvas displays an error message.
The default is a light green. If the specified Color value is null, nothing is done.
|
| setErrorForeground | | public void setErrorForeground(Color c)(Code) | | Set color to be used for the text when the canvas displays an error message.
The default is a dark green. If the specified Color value is null, nothing is done.
|
| setErrorMessage | | public synchronized void setErrorMessage(Controller c, String message)(Code) | | Set an error message to be displayed on the canvas. This method is generally called by
a Controller or a LimitControlPanel. If you call it directly, use null as the first parameter.
Parameters:
c - The Controller, if any, that is calling this routine. This controller will be notifiedwhen the error message is cleared. If the method is not being called by a contrller, thisparameter should be set to null.
Parameters:
message - The error message to be displayed. If the value is null or is a blank string, the current message, if any, is cleared. |
| setHandleMouseZooms | | public void setHandleMouseZooms(boolean handle)(Code) | | Set the "handleMouseZooms" property of this DisplayCanvas. IF the value is true,
then clicking on the canvas will zoom in on the point that is clicked and shift-clicking
will zoom out from that point. Only the CoordinateRect, if any, that contains the point
is zoomed. Furthermore, if the user clicks-and-drags, a rectangle
is drawn. When the mouse is released, the interior of the rectangle is zoomed to fill
the CoordinateRect. This property is false by default.
|
| setUseOffscreenCanvas | | public void setUseOffscreenCanvas(boolean use)(Code) | | Get the "useOffscreenCanvas" property of this DisplayCanvas, which determines whether
double-buffering is used.
|
| update | | public void update(Graphics g)(Code) | | This has been overridden to implemnt double-buffering.
Not meant to be called directly.
