Wie beseitigt man Kanten in JFXPanel?

Question

Ich entwickle eine Java Swing-Karten-Anwendung, es bekommt eine URL und lädt Karten von Google Maps mit verschiedenen Zoomstufen.

Aber die Adressleiste in den Karten ist nervig, ich möchte sie loswerden oder ihren Platz reduzieren.

In meinem Code unten versuchte ich zuerst: Use_iFrame_B=false;

Dies wird eine Karte mit großen Adressleiste wie diese erhalten, und Zoomen funktioniert nicht:

Dann habe ich versucht: Use_iFrame_B=true;

Diese Karten mit Zoom zeigen, hat aber große Kanten:

Also, meine Fragen sind:

1. Wenn Use_iFrame_B = false, wie die Adressleiste in der verstecken erster Fall und immer noch eine Anzeige [roter Ballon] auf der Adresse?
2. So funktioniert Zoom im obigen Fall [Use_iFrame_B = false].
3. Wenn 1 und 2 oben nicht möglich sind, dann würde ich lieber iFrame verwenden, die eine kleinere aussagekräftigere Adresse zeigt und Zoomen funktioniert auch. Aber es hinterlässt große Kanten, wie man diese Kanten los wird, wenn Use_iFrame_B=true?

Hier sind meine Programme:

Answer 1

Okay, fand ich die Antwort:

den Code in JavaFX_Browser_Panel ersetzen:

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>"); 

Mit folgendem:

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);
