How to get rid of edges in JFXPanel? - google-maps

Question

I'm developing a Java Swing map application, it gets a url and loads maps from Google maps at different zoom levels.
But the address bar in the maps are annoying, I want to get rid of it or reduce it's space.
In my code below, I first tried: Use_iFrame_B=false;
This will get a map with large address bar like this, and zooming isn't working :
Then I tried: Use_iFrame_B=true;
This will show maps with zooming, but has large edges:
So, my questions are :
When Use_iFrame_B=false, how to hide the address bar in the first case and still show an indicator [ red balloon ] on the address ?
How to make zoom work in the above case [ Use_iFrame_B=false ].
If 1 and 2 above are not doable, then I'd prefer to use iFrame which will show a smaller more meaningful address and zooming also works. But it leaves large edges, how to get rid of those edges when Use_iFrame_B=true?
Here are my programs:

Answer 1

Alright, I found the answer :
Replace the code in JavaFX_Browser_Panel :
if (new File(Url).exists()) setURL(new File(Url));
else eng.loadContent("<iframe width="+W+" height="+H+" src="+Url+" style=border:0; marginheight=0 marginwidth=0 allowfullscreen></iframe>");
With the following :
String Content="<Html>\n"+
"<style>\n"+
" html,body,div,iframe\n"+
" {\n"+
" height: 100%;\n"+
" overflow: hidden;\n"+
" overflow-x: hidden;\n"+
" overflow-y: hidden;\n"+
" margin: 0; padding: 0;\n"+
" }\n"+
"</style>\n"+
"<iframe width="+W+" height="+H+" src="+Url+" style=border:0></iframe>\n"+
"</Html>";
if (new File(Url).exists()) setURL(new File(Url));
else eng.loadContent(Content);
