|
||||
* The class MapWindow creates a tiled base map from an UTM based TPK from Bremen. Loading the map will be done
|
||||
* by clicking the "Load Map" button. The next 2 buttons creates graphics on top of the map, as follows:
|
||||
*
|
||||
* (1) Draw QGraphicsPathItem
|
||||
* The "Draw QGraphicsPathItem" is creating an QGraphicsItemPath. The QGraphicsItemPath has a blue border line and
|
||||
* is filled with a tranparent green color. See drawQGraphicPathItem().
|
||||
*
|
||||
* (2) Draw Overlay
|
||||
* The "Draw Overlay" is creating GraphicsOverlay with one simple polygon. See buildSymbol().
|
||||
*
|
||||
* All is working as expected when using only one of each button, restart the program and click the other one.
|
||||
* Each of both drawings are ok. In one case you will see a red filled polygon and in other case a green polygon
|
||||
* with a border is drawn on the map.
|
||||
*
|
||||
* But now restart the program click "Draw QGraphicsPathItem" the green area with
|
||||
* a blue border is visible now. After that click "Draw Overlay". The red area of GraphicOverlay polygon appears
|
||||
* on the map. But the green filling of the QGraphicsItemPath has been vanished.
|
||||
*
|
||||
* Restart: Next click the buttons in reversed order ( "Draw Overlay" first and next "Draw QGraphicsPathItem"). On Windows
|
||||
* the behaviour is the same as before - the green polygon filling is not drawn. On Linux a crash in the OpenGl
|
||||
* Driver appears.
