public class MapControl
extends javax.swing.JComponent
implements java.awt.event.ComponentListener, org.gvsig.tools.observer.Observer, org.gvsig.tools.dispose.Disposable

A component that includes a MapContext with support for use it as a particular Behavior.

A developer can register a set of Behavior, but only one (that can be a composition of several) of them can be active. The active one defines the way to work and access with its MapContext's layers. The active behavior, in combination with the appropriate ToolListener will allow user work with a particular tool.

All mouse events produced on this component will be delegated to the current active behavior, the currentMapTool.

Drawing process:

Uses a double buffer for the drawing process of MapContext's information.

If the double buffer wasn't created, creates a new one.

Paints the component according the following algorithm:
If status is UPDATED:
If there is a double buffer:
If there is a behavior for managing the MapControl instance, delegates the drawing process to that behavior, calling: behavior_instance.paintComponent(g).
Else, repaints the current graphical information quickly calling: g.drawImage(image,0,0,null).
Else, (status is OUTDATED, or ONLY_GRAPHICS): executes a quickly repaint of the previous information calling g.drawImage(image,0,0,null), and creates a painting request to delegate the heavy drawing process to the Drawer2's worker thread, according the SingleWorketThread pattern, starting a timer to update (invoking repaint()) the view every delay of 1000 / drawFrameRate ms. during that heavy drawing process, and if its enabled drawAnimationEnabled. The painting request once is being attended, invokes MapContext to draw the layers: mapContext.draw(image, g, cancel,mapContext.getScaleView());

Some notes:

• The painting process can be cancelled calling #cancelDrawing().
• At last resort, the particular implementation of each layer in a MapControl's MapContrext will be that one which will draw the graphical information, and, if supports, which could cancel its drawing subprocess.
• It's possible to force repaint all layers, calling #drawMap(boolean).
• It's possible repaint only the dirty layers, calling #rePaintDirtyLayers().
• It's possible repaint only the GraphicLayer, calling #drawGraphics().

Tools:

A developer can:

• Register each tool as:
  • A single behavior: #addMapTool(String, Behavior).
  • Or, a compound behavior: #addMapTool(String, Behavior).
• Get the current active tool: #getCurrentMapTool().
• Get the current active tool name: #getCurrentTool().
• Get a registered tool: #getMapTool(String).
• Get the name of all tools registered: #getMapToolsKeySet().
• Get all tools registered, including the name they were registered: #getNamesMapTools().
• Determine if has a tool registered: #hasTool(String).
• Set as an active tool, one of the registered: #setTool(String).
• Set as active tool, the previous used: #setPrevTool().
• Set the current tool: #setCurrentMapTool(Behavior).
• Change the draw frame rate: #setDrawFrameRate(int) and #applyFrameRate().
• Get the draw frame rate: #getDrawFrameRate().
• Determine if will repaint this component each time timer finishes: #isDrawAnimationEnabled().
• Change if will repaint this component each time timer finishes: #setDrawAnimationEnabled(boolean).
• Get the shared object that determines if a drawing process must be cancelled or can continue: #getCanceldraw().
• Get the combined tool: #getCombinedTool().
• Set a combined tool: #setCombinedTool(Behavior).
• Remove the combined tool: #removeCombinedTool().

Exception listener:

Adding an ExceptionListener, can get notification about any exception produced:

• Attending a painting request.
• Working with the active tool.
• Applying a zoom in or zoom out operation.

Other:

Other useful capabilities of MapControl:

• Cancel the current drawing process (notifying it also to the inner MapContext instance and its layers): #cancelDrawing().
• Applying a zoom in operation centered at mouse position (without a ToolListener): #zoomIn().
• Applying a zoom out operation centered at mouse position (without a ToolListener): #zoomOut().

public void setCurrentMapTool(Behavior mapTool)

Sets mapTool as this MapControl's current map tool.

Parameters:

mapTool - a map tool, or null to disable the interaction with the user

getCurrentMapTool(), getCurrentTool(), setTool(String), setPrevTool(), addBehavior(String, Behavior), addBehavior(String, Behavior[])

setDrawAnimationEnabled

public static void setDrawAnimationEnabled(boolean drawAnimationEnabled)

Sets if its enabled the repaint that invokes the timer according to #getDrawFrameRate().

Parameters:

drawAnimationEnabled - true to enable the mode; otherwise false

setGridVisibility

public void setGridVisibility(boolean showGrid)

setMapContext

public void setMapContext(org.gvsig.fmap.mapcontext.MapContext model)

Sets a MapContext to this component.

The MapContext has the model, and most of the view, and control logic of the layers of this component, including a ViewPort to adapt the information to the projection, and to display it in the available area.

If model hadn't a ViewPort, assigns the current one to it, otherwise, use its ViewPort.

After assigning the MapContext and ViewPort, sets the same MapContextListener that was using, and changes the status to OUTDATED.

Parameters:

model - this component's MapContext, that includes the ViewPort.

MapContext, getMapContext()

setMapControlDrawer

public void setMapControlDrawer(MapControlDrawer mapControlDrawer)

Parameters:

mapControlDrawer - the mapControlDrawer to set

setPrevTool

public void setPrevTool()

Equivalent operation to undo.

Exchanges the previous tool with the current one.

addBehavior(String, Behavior), addBehavior(String, Behavior[]), setTool(String)

setProjection

public void setProjection(org.cresques.cts.IProjection proj)

Sets the projection to this component's MapContext.

Parameters:

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

See Also:

MapContext.setProjection(IProjection), getProjection()

setRefentEnabled

public void setRefentEnabled(boolean activated)

Sets the snap tools enabled or disabled.

Parameters:

activated - true to enable the snap tools; false to disable them

See Also:

isRefentEnabled()

setTool

public void setTool(java.lang.String toolName)

Sets as current active Behavior associated to this component, that one which is registered and identified by toolName.

Changing the current active behavior for this MapControl, implies also updating the previous behavior tool, and the current cursor.

Parameters:

toolName - name of a registered behavior

getCurrentMapTool(), getCurrentTool()

throwException

protected void throwException(java.lang.Throwable t)

See Also:

ExceptionHandlingSupport.throwException(Throwable)

update

public void update(org.gvsig.tools.observer.Observable observable,
          java.lang.Object notification)

Specified by:

update in interface org.gvsig.tools.observer.Observer

zoomIn

public void zoomIn()

Executes a zoom in operation centered at the center of the extent.

This implementation is designed for being invoked outside a Behavior, for example by an action of pressing a button; and simulates that the event has been produced by releasing the button 1 of the mouse using the registered Behavior in this MapControl object that's responsible for the zoom in operation.

See Also:

zoomOut()

zoomOut

public void zoomOut()

Executes a zoom out operation centered at the center of the extent.

This implementation is thought for being invoked outside a Behavior, for example by an action of pressing a button, and simulates that the event has been produced by releasing the button 1 of the mouse using the registered Behavior in this MapControl object that's responsible for the zoom out operation.
