107 | * can be a composition of several) of them can be active. The active one
|

108 | * defines the way to work and access with its <code>MapContext</code>'s layers.
|
||
109 | * The active behavior, in combination with the appropriate {@link ToolListener
|

110 | * ToolListener} will allow user work with a particular <i>tool</i>.

132 | * Paints the component according the following algorithm: <br>

133 | *   If <i>status</i> is <i>UPDATED</i>:<br>
|
||
134 | *     If there is a <i>double buffer</i>:<br>
|
||
135 | *       If there is a <i>behavior</i> for managing the
|
||
136 | * <code>MapControl</code> instance, delegates the drawing process to that
|
||
137 | * behavior, calling: <code><i>behavior_instance</i>.paintComponent(g)</code>.<br>
|
||
138 | *       Else, repaints the current graphical information quickly
|
||
139 | * calling: <code>g.drawImage(image,0,0,null)</code>.<br>
|
||
140 | *   Else, (<i>status</i> is <i>OUTDATED</i>, or <i>ONLY_GRAPHICS</i>):
|
||
141 | * executes a quickly repaint of the previous information calling
|
||
142 | * <code>g.drawImage(image,0,0,null)</code>, and creates a <i>painting
|
||
143 | * request</i> to delegate the heavy drawing process to the {@link Drawer2
|
||
144 | * Drawer2}'s worker thread, according the <i>SingleWorketThread</i> pattern,
|
||
145 | * starting a timer to update (invoking <code>repaint()</code>) the view every
|
||
146 | * delay of <code>1000 / drawFrameRate</code> ms. during that heavy drawing
|
||
147 | * process, and if its enabled <code>drawAnimationEnabled</code>. The
|
||
148 | * <i>painting request</i> once is being attended, invokes
|
||
149 | * <code>MapContext</code> to draw the layers:

150 | * <code>mapContext.draw(image, g, cancel,mapContext.getScaleView());</code>
|

154 | * <ul>
|
||
155 | * <li>The painting process can be cancelled calling {@link #cancelDrawing()
|

156 | * #cancelDrawing()}.</li>
|

157 | * <li>At last resort, the particular implementation of each layer in a

158 | * <code>MapControl</code>'s <code>MapContrext</code> will be that one which

159 | * will draw the graphical information, and, if supports, which could cancel its

160 | * drawing subprocess.</li>
|

161 | * <li>It's possible to force repaint all layers, calling
|

162 | * {@link #drawMap(boolean doClear) #drawMap(boolean)}.</li>
