|
||
81 | 20098 | jmvivo | * <p>A component that includes a {@link MapContext MapContext} with support for use it as a particular {@link Behavior Behavior}.</p>
|
82 | 1223 | fernando | *
|
83 | 20098 | 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
|
84 | * defines the way to work and access with its <code>MapContext</code>'s layers. The active behavior, in combination with the appropriate
|
||
85 | * {@link ToolListener ToolListener} will allow user work with a particular <i>tool</i>.</p>
|
||
86 | *
|
||
87 | * <p>All mouse events produced on this component will be delegated to the current active behavior, the <i>currentMapTool</i>.</p>
|

|
89 | 20098 | jmvivo | * <p><b>Drawing process:</b></p>
|
90 | 20397 | vcaballero | *
|
91 | 20098 | jmvivo | * <p>Uses a double buffer for the drawing process of <code>MapContext</code>'s information.</p>
|
92 | 20397 | vcaballero | *
|
93 | 20098 | jmvivo | * <p>If the double buffer wasn't created, creates a new one.</p>
|
94 | 20397 | vcaballero | *
|
95 | 20098 | jmvivo | * <p>Paints the component according the following algorithm:
|
96 | * <br>
|
||
97 | *   If <i>status</i> is <i>UPDATED</i>:<br>
|
||
98 | *     If there is a <i>double buffer</i>:<br>
|
||
99 | *       If there is a <i>behavior</i> for managing the <code>MapControl</code> instance, delegates
|
||
100 | * the drawing process to that behavior, calling: <code><i>behavior_instance</i>.paintComponent(g)</code>.<br>
|
||
101 | *       Else, repaints the current graphical information quickly calling: <code>g.drawImage(image,0,0,null)</code>.<br>
|
||
102 | *   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OUTDATED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
|
||
103 | * 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
|
||
104 | * (invoking <code>repaint()</code>) the view every delay of <code>1000 / drawFrameRate</code> ms. during that heavy drawing process, and if its enabled <code>drawAnimationEnabled</code>. The <i>painting request</i> once is being attended, invokes <code>MapContext</code> to
|
||
105 | 20397 | vcaballero | * draw the layers: <code>mapContext.draw(image, g, cancel,mapContext.getScaleView());</code>
|
106 | 20098 | jmvivo | * <br>
|
107 | * <p>Some notes:
|
||
108 | * <ul>
|
||
109 | * <li>The painting process can be cancelled calling {@link #cancelDrawing() #cancelDrawing()}.</li>
|
||
110 | * <li>At last resort, the particular implementation of each layer in a <code>MapControl</code>'s <code>MapContrext</code>
|
||
111 | * will be that one which will draw the graphical information, and, if supports, which could cancel its drawing subprocess.</li>
|
||
112 | * <li>It's possible to force repaint all layers, calling {@link #drawMap(boolean doClear) #drawMap(boolean)}.</li>
|
||
113 | * <li>It's possible repaint only the dirty layers, calling {@link #rePaintDirtyLayers() #rePaintDirtyLayers()}.</li>
|
||
114 | * <li>It's possible repaint only the {@link GraphicLayer GraphicLayer}, calling {@link #drawGraphics() #drawGraphics()}.</li>
