public class ZoomPanel
extends OMToolComponent
implements java.awt.event.ActionListener, java.io.Serializable

Bean to zoom the Map.

This bean is a source for ZoomEvents. It is a simple widget with a ZoomIn button and a ZoomOut button. When a button is pressed, the appropriate zoom event is fired to all registered listeners.

Constructor Detail

### ZoomPanel

    public ZoomPanel()

  Construct the ZoomPanel.

Method Detail

### getZoomInFactor

    public float getZoomInFactor()

  Get the Zoom In Factor.

  Returns:
    float the degree by which map scale will be multiplied when zoom in button is pressed

### setZoomInFactor

    public void setZoomInFactor(float factor)

  Sets the Zoom In factor. The factor must be < 1.0. (otherwise it would make ZoomIn into a ZoomOut).

  Parameters:
    `factor` - the degree by which map scale should be multiplied

### getZoomOutFactor

    public float getZoomOutFactor()

  Get the Zoom Out Factor.

  Returns:
    float the degree by which map scale will be multiplied when zoom out button is pressed

### setZoomOutFactor

    public void setZoomOutFactor(float factor)

  Sets the Zoom Out Factor. The factor must be > 1.0 (otherwise it would turn ZoomOut into ZoomIn).

  Parameters:
    `factor` - the degree by which map scale should be multiplied.

### getButton

    protected javax.swing.JButton getButton(java.lang.String name,
                                            java.lang.String info,
