Detailed Description
MapArea Class.
Example of a Map.
This class loads the map to the drawing area including its ability to do zooming and panning. In this case, the user could also move the waypoints around the map and the terminal would show the coordinate, consistent with current zoom and pan level (see image below). In addition, to load the point in the map from flightPlan to the window, the coordinate has to be transformed back to the coordinate of the window to make it consistent (see image below).
The Mathematics of Coordinate Transformation.
This class also asks the user to input the coordinate of top-left and bottom-right corners of the map. From these information, the map could be rotated such that the north is pointing up. The constraints in this code is that the north must be in increment of 90 degrees from the real north. This class is unable to rotate with custom angle.
This class also enables user to input waypoints by clicking a point in the map and modify them. The possible modifications are adding, deleting, and moving waypoints. These modifications could be done by series of keyboard pressing and mouse clicking. To achieve this, "A" or "a" is assigned to add waypoint, "M" or "m" is assigned to move waypoint, and "D" or "d" is assigned to delete waypoint. The procedure is followed:
1) Adding Waypoint
Press "A" or "a" and all the waypoints will be highlighted by a red circle around them.
Click the previous waypoint to where the new waypoint is going to be added.
Click a point in the map and the new waypoint will be added after the previously chosen waypoint.
Adding Waypoint.
2) Moving Waypoint
Press "M" or "m" and all the waypoints will be highlighted by a red circle around them.
Click the waypoint that wants to be moved.
Click a point in the map and the waypoint will move to the new location that was clicked.
Moving Waypoint.
3) Deleting Waypoint
Press "D" or "d" and all the waypoints will be highlighted by a red circle around them.
Click the waypoint that wants to be deleted and it will be deleted.
Deleting Waypoint.
