public class MapOverview
extends MapControl
implements ViewPortListener

Lightweight MapControl that uses another MapControl's MapContext, and updates any rectangular extent selected, to the associated MapControl.

Both MapControl instances work in the same projection. And, always, the not undefined adjusted extent of the associated one, will be enhanced as a red-bordered grey-filled rectangle in this one. Furthermore, draws a horizontal and vertical this component's width or height, black lines centered in that rectangle.

Constructor Detail

MapOverview

public MapOverview(MapControl mapAssoc)

Creates a MapOverview instance associated to mapAssoc.

Parameters:

mapAssoc - MapControl this component will be the overview

Method Detail

getAssociatedMapContext

public MapContext getAssociatedMapContext()

See Also:

MapControl.getMapContext()

getAssociatedMapControl

public MapControl getAssociatedMapControl()

Gets the MapControl instance that wrappers.

Returns:

the MapControl instance that wrappers

extentChanged

public void extentChanged(ExtentEvent evExtent)

Description copied from interface: ViewPortListener

Called when the extent of the view port has changed.

Specified by:

extentChanged in interface ViewPortListener

Parameters:

evExtent - an extend event object

refreshExtent

public void refreshExtent()

If this had no extent, calls #delModel(), otherwise recalculates this component's view port extent as the union of all extents of all layers of this map.

refreshOverView

public void refreshOverView(Envelope r)

Repaints this component updating its extent.

Parameters:

r - the new extent

paintComponent

protected void paintComponent(Graphics g)

Paints this component's graphical information using a 8-bit RGBA color double buffer, drawing a red-bordered grey-filled rectangle enhancing the extent selected, and a horizontal and vertical this component's width or height, black lines centered in that rectangle.

Overrides:

paintComponent in class MapControl

See Also:

JComponent.paintComponent(java.awt.Graphics), Drawer2

setModel

public void setModel(MapContext model)

Sets a MapContext to this component, configuring it to manage view port events produced in the associated MapControl and this one's view port.

This MapContext's projection will be the same as the associated MapControl's one.

Setting the model includes the following steps:

• 1.- set model as the MapContext of this.
• 2.- set as model projection, the associated MapControl's projection.
• 3.- set this as view port listener of the associated MapControl's view port.
• 4.- set this as view port listener of this MapContext's view port

Parameters:

model - data to set

backColorChanged

public void backColorChanged(ColorEvent e)

Removes this component as listener of the the associated MapControl and this one's view port. Besides, removes the extent.

Specified by:

backColorChanged in interface ViewPortListener

Parameters:

e - a color event object

projectionChanged

public void projectionChanged(ProjectionEvent e)

Description copied from interface: ViewPortListener

Called when the projection of the view port has changed.

Specified by:

projectionChanged in interface ViewPortListener

Parameters:

e - a projection event object

See Also:

ViewPortListener.projectionChanged(ProjectionEvent), MapControl.setProjection(IProjection)

setProjection

public void setProjection(IProjection proj)

Unimplemented.

Can't change the projection, because must be the same as the one of the associated MapControl instance.

Overrides:

setProjection in class MapControl

Parameters:

proj - the kind of projection to this component's MapContext

See Also:

MapContext.setProjection(IProjection), MapControl.getProjection()

calculateSnapPoint

public void calculateSnapPoint(Point point)

Description copied from class: MapControl

Tries to find the nearest geometry or grid control point by the position of the current snap tool.

Prioritizes the grid control points than the geometries ones.

If finds any near, stores the map and pixel coordinates for the snap, and enables the bForceCoord attribute for the next draw of the mouse's cursor.

Overrides:

calculateSnapPoint in class MapControl

Parameters:

point - current mouse 2D position
