83 | /**
|
||
84 | 20100 | jmvivo | * <p>A component that includes a {@link MapContext MapContext} with support for use it as a particular {@link Behavior Behavior}.</p>
|
85 | 1223 | fernando | *
|
86 | 20100 | jmvivo | * <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
|
87 | * defines the way to work and access with its <code>MapContext</code>'s layers. The active behavior, in combination with the appropriate
|
||
88 | * {@link ToolListener ToolListener} will allow user work with a particular <i>tool</i>.</p>
|
||
89 | *
|
||
90 | * <p>All mouse events produced on this component will be delegated to the current active behavior, the <i>currentMapTool</i>.</p>
|
||
91 | *
|
||
92 | * <p><b>Drawing process:</b></p>
|
||
93 | *
|
||
94 | * <p>Uses a double buffer for the drawing process of <code>MapContext</code>'s information.</p>
|
||
95 | *
|
||
96 | * <p>If the double buffer wasn't created, creates a new one.</p>
|
||
97 | *
|
||
98 | * <p>Paints the component according the following algorithm:
|
||
99 | * <br>
|
||
100 | *   If <i>status</i> is <i>UPDATED</i>:<br>
|
||
101 | *     If there is a <i>double buffer</i>:<br>
|
||
102 | *       If there is a <i>behavior</i> for managing the <code>MapControl</code> instance, delegates
|
||
103 | * the drawing process to that behavior, calling: <code><i>behavior_instance</i>.paintComponent(g)</code>.<br>
|
||
104 | *       Else, repaints the current graphical information quickly calling: <code>g.drawImage(image,0,0,null)</code>.<br>
|
||
105 | *   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OUTDATED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
|
||
106 | * 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
|
||
107 | * (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
|
||
108 | * draw the layers: <code>mapContext.draw(image, g, cancel,mapContext.getScaleView());</code>
|
||
109 | * <br>
|
||
110 | * <p>Some notes:
|
||
111 | * <ul>
|
||
112 | * <li>The painting process can be cancelled calling {@link #cancelDrawing() #cancelDrawing()}.</li>
|
||
113 | * <li>At last resort, the particular implementation of each layer in a <code>MapControl</code>'s <code>MapContrext</code>
|
||
114 | * will be that one which will draw the graphical information, and, if supports, which could cancel its drawing subprocess.</li>
|
||
115 | * <li>It's possible to force repaint all layers, calling {@link #drawMap(boolean doClear) #drawMap(boolean)}.</li>
|
||
116 | * <li>It's possible repaint only the dirty layers, calling {@link #rePaintDirtyLayers() #rePaintDirtyLayers()}.</li>
|
||
117 | * <li>It's possible repaint only the {@link GraphicLayer GraphicLayer}, calling {@link #drawGraphics() #drawGraphics()}.</li>
|
||
118 | * </ul>
|
||
119 | * </p>
|
||
120 | *
|
||
121 | * <p><b>Tools:</b></p>
|
||
122 | *
|
||
123 | * <p>A developer can:
|
||
124 | * <ul>
|
||
125 | * <li>Register each tool as:
|
||
126 | * <ul>
|
||
127 | * <li>A single behavior: {@link #addMapTool(String, Behavior) #addMapTool(String, Behavior)}.</li>
|
||
128 | * <li>Or, a compound behavior: {@link #addMapTool(String, Behavior) #addMapTool(String, Behavior)}.</li>
|
||
129 | * </ul>
|
||
130 | * </li>
|
||
131 | * <li>Get the current active tool: {@link #getCurrentMapTool() #getCurrentMapTool()}.</li>
|
||
132 | * <li>Get the current active tool name: {@link #getCurrentTool() #getCurrentTool()}.</li>
|
||
133 | * <li>Get a registered tool: {@link #getMapTool(String) #getMapTool(String)}.</li>
|
||
134 | 20357 | vcaballero | * <li>Get the combined tool: {@link #getCombinedTool() #getCombinedTool()}</li>
|
135 | 20100 | jmvivo | * <li>Get the name of all tools registered: {@link #getMapToolsKeySet() #getMapToolsKeySet()}.</li>
|
136 | * <li>Get all tools registered, including the name they were registered: {@link #getNamesMapTools() #getNamesMapTools()}.</li>
|
||
137 | * <li>Determine if has a tool registered: {@link #hasTool(String) #hasTool(String)}.</li>
|
||
138 | * <li>Set as an active tool, one of the registered: {@link #setTool(String) #setTool(String)}.</li>
|
||
139 | * <li>Set as active tool, the previous used: {@link #setPrevTool() #setPrevTool()}.</li>
|
||
140 | 20357 | vcaballero | * <li>Set the combined tool: {@link #setCombinedTool(Behavior) #setCombinedTool(Behavior)}.</li>

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

156 | * <p>Other useful capabilities of <code>MapControl</code>:
