/**

84 |
* FFrame used for embedding a View in the Layout. The View is not actually
|
85 |
* inserted on the Layout, but it is used together with the MapContext
|
86 |
* in order do draw an image which is then painted on the FFrame. Therefore,
|
87 |
* no MapControl is used in current implementation, but a similar behavior
|
88 |
* is simulated by the FFrameView. The original MapContext is cloned when
|
89 |
* assigned to the FFrameView, which is then used for drawing.
|
90 |
*
|
91 |
* The FFrameView and the associated View can be synchronized, depending
|
92 |
* on the values of {@link #getTypeScale()} and {@link #getLinked()}.
|
93 |
*
|
94 |
* The main synchronization logic is kept on two internal classes:
|
95 |
* {@link OwnMapContextListener} and {@link ViewDocListener}. The first one
|
96 |
* listens for events on the FFrameView and synchronizes the View accordingly.
|
97 |
* The second one listens for events on the View and synchronizes the FFrameView
|
98 |
* accordingly. There synchronization process is flagged using
|
99 |
* {@link #b_updating} and {@link #b_updating}, in order
|
100 |
* to avoid incurring on infinite synchronization loops.
