[attach-detach] MapLabel to marker while EventHandler [ENTERED-EXITED]

[oosam2]

Hi Peter-Josef Meisch :)

I can`t attachLabel() to marker while EventHandler is MARKER_ENTERED and detachLabel() to marker while EventHandler is MARKER_EXITED
Ex

mapView.addEventHandler(MarkerEvent.MARKER_ENTERED, event -> {
     event.consume();
     event.getMarker().attachLabel(new MapLabel("MARKER_ENTERED"));
});

mapView.addEventHandler(MarkerEvent.MARKER_EXITED, event -> {
     event.consume();
     event.getMarker().detachLabel();
});

I found simple css solution
-with MARKER_ENTERED I add css
display: block;
-with MARKER_EXITED I add css
display: none;

can you added to next version?

sometime i get marker img highlight

ma by this css useful
user-select: none;

thank you very much for this library

     event.consume();
     event.getMarker().attachLabel(new MapLabel("MARKER_ENTERED"));
});

The label you create in the event handler will go out of scope as soon as the event handler is exited and the it will be garbage collected and removed. You have to create the label outside of this function and then in the handler you can attach it or detach it. You will have to set the label to unvisible after detaching it. As long as the label is attached to the marker, it will have the same visibility state.

As for the highlighted images: I have seen this now just once, but have not yet found what causes this element to be selected; I cannot reproduce it all the times
