All Implemented Interfaces:

InteractionListener, GridContainer, Header, java.awt.image.ImageObserver, java.awt.MenuContainer, java.beans.PropertyChangeListener, java.io.Serializable, java.util.EventListener, javax.swing.Scrollable

Direct Known Subclasses:

DateGridHeader, SubRowGridHeader

public abstract class AbstractGridHeader
extends javax.swing.JComponent
implements Header, java.beans.PropertyChangeListener, GridContainer, InteractionListener, javax.swing.Scrollable

Boiler plate implementation for a Header that is a JComponent. Takes care of the action listener handling and returns a JScrollPane as the component to use.

This class is itself a JComponent which bounds is automatically laid out to match the tracked component in the tracked dimension. Subclasses is responsible for returning a size (fixed) to use in the other, secondary, dimension.

This component works much like a mini-dateArea.

Note that the actual paiting is done by Decorators.

All decorators will be notified of all events by a call to Decorator.processEvent(java.awt.AWTEvent) in the overridded processEvent(java.awt.AWTEvent).

By default mouse, mouse motion and key events are enabled and will be sent to the decorators. (and processEvent(java.awt.AWTEvent))

Constructor Detail

AbstractGridHeader

                             javax.swing.JComponent trackedComponent,
                             int edge)

Constructor.

Parameters:

trackedComponent - The component that this header is a header for. When this component is added to the component herarchy it registers itself with the tracked component and when this is removed from the component hierarchy this header will unregister itself with that same component. This shuld make for an automatic disposal without memory leaks.

Method Detail

addNotify

public void addNotify()

Overrides:

addNotify in class javax.swing.JComponent

removeNotify

public void removeNotify()

Overrides:

removeNotify in class javax.swing.JComponent

paint

public void paint(java.awt.Graphics g)

Overrides:

paint in class javax.swing.JComponent

paintComponent

protected void paintComponent(java.awt.Graphics g)

Paints the decorators

Overrides:

paintComponent in class javax.swing.JComponent

Parameters:

g - The object to draw in

setBackground

public void setBackground(java.awt.Color bg)

Propagate the background to the mandatory scroll pane.

Overrides:

setBackground in class javax.swing.JComponent

Parameters:

bg - The new background.

setBackgroundPaint

public void setBackgroundPaint(java.awt.Paint p)

getBackgroundPaint

public java.awt.Paint getBackgroundPaint()

print

public void print(java.awt.Graphics g)

Overrides:

print in class javax.swing.JComponent

getPrimDim

public int getPrimDim()

Deprecated. Use getPrimaryDimension() instead.

Returns the primary dimension for this header. (long dimension). E.g. SwingConstants.HORIZONTAL

Returns:

The primary dimension for this header.

getPrimaryDimension

public int getPrimaryDimension()

Returns the primary dimension for this header. (long dimension). E.g. SwingConstants.HORIZONTAL

Returns:

The primary dimension for this header.

getEdge

public int getEdge()

Returns what edge (E.g. SwingConstants.(TOP | LEFT | BOTTOM | RIGHT) the header will reside. Note that the actual placement of this component is not done by this component, that is done by a layout manager of the parent. This value is for interpreting the date ranges in the cell rows.

Returns:

The edge.

isBeforeGrid

public boolean isBeforeGrid()

Returns if the the header is visually "before" the tracked grid cells (TOP & LEFT) or after (BOTTOM & RIGHT)

Returns:

If the the header is visually "before" the tracked grid cells (TOP & LEFT) or after (BOTTOM & RIGHT)

processEvent

protected void processEvent(java.awt.AWTEvent e)

Overrides:

processEvent in class java.awt.Container

clearBackBuffer

public void clearBackBuffer()

If a back buffer is being used to cache the graphics contents of the header (for speed) it can be cleared with this method. That will force it to be repainted next repaint cycle. This can for instance be done when mouse enteres or moves/drags on the header if mouse over effects for it is beeing used. The back buffer might be turned off all together for these kind of headers but that would make it repaint slower. Note that the back buffer will always be recreated when the header is changing size.

isCacheWithBackBuffer

public boolean isCacheWithBackBuffer()

Return if a back buffered is being uesed to cache the contents of the header.

Returns:

true if so. false is default.

See Also:

setCacheWithBackBuffer(boolean)

setCacheWithBackBuffer

public void setCacheWithBackBuffer(boolean cacheWithBackBuffer)

Sets if a back buffered is being uesed to cache the contents of the header. This can increase speed for re-redrawing the header by a factor of 100. Should be turned on for static (no changing) headers and might be used for dynamic headers (e.g. with mouse over effects). If to be used with dynamic headers see clearBackBuffer() which will probably have to be called for every mouse event or the effects will not appear.

Parameters:

cacheWithBackBuffer - true turns it on. false is default.

addInteractionListener

public void addInteractionListener(InteractionListener l)

Adds a listener that listens to InteractionEvents. Interaction events are normally fired by the Interaction/Interactor/AbstractInteractionBroker framework, used for instance by the AShape framework.
This class is actually a re-dispatcher of these events. It is itself an InteractionListener and registers itself on the interaction observable objects it creates. For instance ActivityViews.

Parameters:

l - The listener to add

addInteractionListener

public void addInteractionListener(InteractionListener l,
                                   boolean asWeakRef)

Adds a listener that listens to InteractionEvents. Interaction events are normally fired by the Interaction/Interactor/AbstractInteractionBroker framework, used for instance by the AShape framework.

Parameters:

l - The listener to add

asWeakRef - If the listener should be added wrapped in a WeakReference. This defers memory leak problems since the garbage collector can collect the listener if it is only referenced from this list.
Note! This (weak reference) can not be used with listeners that doesn't have another real (a.k.a Strong) reference to it, as for instance an annonymous inner class. If one such listener is added it will be removed almost immediately by the garbage collector.

removeInteractionListener

public void removeInteractionListener(InteractionListener l)

Removes the listener.

Parameters:

l - The listener to remove.

fireInteractionOccured

protected void fireInteractionOccured(InteractionEvent e)

Notifies all listeners of the the event.
