I just released mapjfx version 1.10.1 it should be found shortly at maven central, the artifact coordinates are:
<dependency> <groupId>com.sothawo</groupId> <artifactId>mapjfx</artifactId> <version>1.10.1</version> </dependency>
The source is available at GitHub.
Now there is a custom event for context (right) clicks in the map., not only for the markers and labels.
Comments and contributions welcome.
