Class IlvDelayedDecoration

java.lang.Object

ilog.views.IlvIndexedSet

ilog.views.IlvManagerLayer

ilog.views.maps.grids.IlvDelayedDecoration

All Implemented Interfaces:

IlvManagerViewDecoration, IlvPersistentObject, ActionListener, Serializable, EventListener

public class IlvDelayedDecoration
extends IlvManagerLayer
implements IlvManagerViewDecoration, ActionListener

This decoration and layer class is used to delay the painting of another delegate decoration/layer (possibly one that takes a long time to paint). By default, painting the view triggers the painting of all decorations.
Using the IlvDelayedDecoration, painting is not done immediately, but after a short delay. During this delay, the user can still, for example, pan or scroll the view, which resets the delay.
However, if the delegate decoration is a subclass of IlvManagerLightViewDecoration, the "paintLight" will be called immediately. IlvDelayedDecoration delayed decoration can either be used as an IlvManagerLayer or an IlvManagerViewDecoration.

Since:

JViews 7.5

Constructor Detail

IlvDelayedDecoration

public IlvDelayedDecoration(int refreshDelay)

Creates a delayed decoration.

Parameters:

refreshDelay -

IlvDelayedDecoration

public IlvDelayedDecoration(IlvInputStream stream)
                     throws IlvReadFileException

Constructs a decoration from serialized data.

Parameters:

stream - stream to read from.

Throws:

IlvReadFileException

Method Detail

write

public void write(IlvOutputStream stream)
           throws IOException

Writes the layer to an output stream.

Specified by:

write in interface IlvPersistentObject

Overrides:

write in class IlvManagerLayer

Parameters:

stream - stream to write into.

Throws:

IOException

actionPerformed

public void actionPerformed(ActionEvent e)

Repaints the view when the timer has expired, indicating the delegate decoration to redraw.

Specified by:

actionPerformed in interface ActionListener

See Also:

ActionListener.actionPerformed(java.awt.event.ActionEvent)

getDecoration

public IlvManagerViewDecoration getDecoration()

Returns the delegate decoration to repaint.

Returns:

The delegate decoration.

getRefreshDelay

public int getRefreshDelay()

Returns the timer refresh delay.

Returns:

The timer refresh delay.

paint

public void paint(Graphics dst,
                  IlvManagerView view)

Paints this decoration. This either resets/starts the timer or draws the decoration (if already in a timer trigger).

Specified by:

paint in interface IlvManagerViewDecoration

Parameters:

Overrides:

draw in class IlvManagerLayer

Parameters:

dst - The Graphics to draw.

v - The view of the manager.

                  IlvTransformer t)

Prints the layer with a specified transformer.

Overrides:

print in class IlvManagerLayer

Parameters:

dst - The graphics.

area - The rectangle of the layer to print in the manager coordinate system.

t - The transformer used to print the content.
