/**
|
82 |
* <p>A component that includes a {@link MapContext MapContext} with support for use it as a particular {@link Behavior Behavior}.</p>
|
83 |
*
|
84 |
* <p>A developer can register a set of <code>Behavior</code>, but only one (that can be a composition of several) of them can be active. The active one
|
85 |
* defines the way to work and access with its <code>MapContext</code>'s layers. The active behavior, in combination with the appropriate
|
86 |
* {@link ToolListener ToolListener} will allow user work with a particular <i>tool</i>.</p>
|
87 |
*
|
88 |
* <p>All mouse events produced on this component will be delegated to the current active behavior, the <i>currentMapTool</i>.</p>
|
89 |
*
|
90 |
* <p><b>Drawing process:</b></p>
|
91 |
*
|
92 |
* <p>Uses a double buffer for the drawing process of <code>MapContext</code>'s information.</p>
|
93 |
*
|
94 |
* <p>If the double buffer wasn't created, creates a new one.</p>
|
95 |
*
|
96 |
* <p>Paints the component according the following algorithm:
|
97 |
* <br>
|
98 |
*   If <i>status</i> is <i>UPDATED</i>:<br>
|
99 |
*     If there is a <i>double buffer</i>:<br>
|
100 |
*       If there is a <i>behavior</i> for managing the <code>MapControl</code> instance, delegates
|
101 |
* the drawing process to that behavior, calling: <code><i>behavior_instance</i>.paintComponent(g)</code>.<br>
|
102 |
*       Else, repaints the current graphical information quickly calling: <code>g.drawImage(image,0,0,null)</code>.<br>
|
103 |
*   Else, (<i>status</i> is <i>OUTDATED</i>, or <i>ONLY_GRAPHICS</i>): executes a quickly repaint of the previous information calling <code>g.drawImage(image,0,0,null)</code>, and creates
|
104 |
* a <i>painting request</i> to delegate the heavy drawing process to the {@link Drawer2 Drawer2}'s worker thread, according the <i>SingleWorketThread</i> pattern, starting a timer to update
|
105 |
* (invoking <code>repaint()</code>) the view every delay of 360 ms. during that heavy drawing process. The <i>painting request</i> once is being attended, invokes <code>MapContext</code> to
|
106 |
* draw the layers: <code>mapContext.draw(image, g, cancel,mapContext.getScaleView());</code>
|
107 |
* <br>
|
108 |
* <p>Some notes:
|
109 |
* <ul>
|
110 |
* <li>The painting process can be cancelled calling {@link #cancelDrawing() #cancelDrawing()}.</li>
|
111 |
* <li>At last resort, the particular implementation of each layer in a <code>MapControl</code>'s <code>MapContrext</code>
|
112 |
* will be that one which will draw the graphical information, and, if supports, which could cancel its drawing subprocess.</li>
|
113 |
* <li>It's possible to force repaint all layers, calling {@link #drawMap(boolean doClear) #drawMap(boolean)}.</li>
|
114 |
* <li>It's possible repaint only the dirty layers, calling {@link #rePaintDirtyLayers() #rePaintDirtyLayers()}.</li>
|
115 |
* <li>It's possible repaint only the {@link GraphicLayer GraphicLayer}, calling {@link #drawGraphics() #drawGraphics()}.</li>
|
116 |
* </ul>
|
117 |
* </p>
|
118 |
*
|
119 |
* <p><b>Tools:</b></p>
|
120 |
*
|
121 |
* <p>A developer can:
|
122 |
* <ul>
|
123 |
* <li>Register each tool as:
|
124 |
* <ul>
|
125 |
* <li>A single behavior: {@link #addMapTool(String, Behavior) #addMapTool(String, Behavior)}.</li>
|
126 |
* <li>Or, a compound behavior: {@link #addMapTool(String, Behavior) #addMapTool(String, Behavior)}.</li>
|
127 |
* </ul>
|
128 |
* </li>
|
129 |
* <li>Get the current active tool: {@link #getCurrentMapTool() #getCurrentMapTool()}.</li>
|
130 |
* <li>Get the current active tool name: {@link #getCurrentTool() #getCurrentTool()}.</li>
|
131 |
* <li>Get a registered tool: {@link #getMapTool(String) #getMapTool(String)}.</li>
|
132 |
* <li>Get the name of all tools registered: {@link #getMapToolsKeySet() #getMapToolsKeySet()}.</li>
|
133 |
* <li>Get all tools registered, including the name they were registered: {@link #getNamesMapTools() #getNamesMapTools()}.</li>
|
134 |
* <li>Determine if has a tool registered: {@link #hasTool(String) #hasTool(String)}.</li>
|
135 |
* <li>Set as an active tool, one of the registered: {@link #setTool(String) #setTool(String)}.</li>
|
136 |
* <li>Set as active tool, the previous used: {@link #setPrevTool() #setPrevTool()}.</li>
|
137 |

|
139 |
*
|
140 |
* <p><b>Exception listener:</b></p>
|
141 |
*
|
142 |
* <p> Adding an <code>ExceptionListener</code>, can get notification about any exception produced:
|
143 |
* <ul>
|
144 |
* <li>Attending a <i>painting request</i>.</li>
|
145 |
* <li>Working with the active tool.</li>

|
153 |

154 |
* <li>Cancel the current drawing process (notifying it also to the inner

* <code>MapContext</code> instance and its layers): {@link #cancelDrawing() #cancelDrawing()}.</li>
|
156 |
* <li>Applying a <i>zoom in</i> operation centered at mouse position (without a <code>ToolListener</code>): {@link #zoomIn() #zoomIn()}.</li>
