Constructor Detail

ChartRegion

public ChartRegion()

Default constructor for chart region.

ChartRegion

public ChartRegion(com.klg.jclass.chart.JCChart p)

Constructor that connects the ChartRegion to a parent JCChart.

Parameters:

p - parent chart

Method Detail

paintComponent

public void paintComponent(Graphics gc)

Overrides:

paintComponent in class JComponent

getPreferredSize

public Dimension getPreferredSize()

Returns the manually set preferred size for the ChartRegion instance.

Overrides:

getPreferredSize in class JComponent

Returns:

manually set preferred size, or null is none manually set

setPreferredSize

public void setPreferredSize(Dimension dim)

Sets the preferred size manually for this ChartRegion instance.

Overrides:

setPreferredSize in class JComponent

Parameters:

dim - the preferred size

getDrawingArea

public Rectangle getDrawingArea()

Gets the bounding rectangle of the component's drawing area, (its area minus the shadows and insets).

Returns:

See Also:

JComponent.setBorder(javax.swing.border.Border)

getDrawingArea

public void getDrawingArea(Rectangle rect)

Gets the bounding rectangle of the component's drawing area, (its area minus the insets).

Parameters:

rect -

See Also:

JComponent.setBorder(javax.swing.border.Border)

getCellRendererPane

public CellRendererPane getCellRendererPane()

Gets the cell renderer pane for this ChartRegion. Used to render HTML encoded text with a JLabel.

Returns:

getChanged

public boolean getChanged()

Gets the value of the Changed property. The Changed property determines whether the object needs to be recalculated.

Specified by:

getChanged in interface Changeable

Returns:

true if the object has been changed and needs recalculation; false otherwise

getChanged

public boolean getChanged(int mask)

Checks the value of the ChangedFlag property for the specified mask (see Changeable for a list of valid masks). The ChangedFlag property determines the action the object needs to take in regards to the current change.

Specified by:

getChanged in interface Changeable

Parameters:

mask -

Returns:

true if the specified mask exists in the ChangedFlag property; false otherwise

isChanged

public final boolean isChanged()

Gets the value of the Changed property. The Changed property determines whether the object needs to be recalculated.

Specified by:

isChanged in interface Changeable

Returns:

true if the object has been changed and needs recalculation; false otherwise

isChanged

public final boolean isChanged(int mask)

Checks the value of the ChangedFlag property for the specified mask (see Changeable for a list of valid masks). The ChangedFlag property determines the action the object needs to take in regards to the current change.

Specified by:

isChanged in interface Changeable

Parameters:

mask -

Returns:

true if the specified mask exists in the ChangedFlag property; false otherwise

setChanged

public void setChanged(boolean c,
                       int cf)

Sets the value of the Changed property and updates the parent object. The Changed property determines whether the object needs to be recalculated.

Specified by:

setChanged in interface Changeable

Parameters:

c - new value for Changed

cf -

setChanged

public void setChanged(boolean n,
                       int cf,
                       boolean updateParent)

Sets the value of the Changed property. The Changed property determines whether the object needs to be recalculated.

Specified by:

setChanged in interface Changeable

Parameters:

n - new value for Changed

updateParent - if true, the parent is updated; otherwise, the parent is not updated (the "update" semantics are up to the implementor)

cf -

updateParent

public void updateParent(int cf)

isBatched

public boolean isBatched()

Specified by:

isBatched in interface Changeable
