Re: jsinterop with browser-specific api
I suppose it'll eventually be in a jsinterop util class but for now you
have to use JSNI: https://github.com/gwtproject/gwt/issues/9364

Thank you for answer! Writing it by hand is annoying, but maybe later it

Maybe you know.. How can I use 'in' operator?

Re: jsinterop with browser-specific api
Actually, in this case, you could also do it like this:
@JsOverlay
public void exitFullScreen() {
ExitFullScreen exitFullScreen = getExitFullScreen();
if (exitFullScreen == null) {
exitFullScreen = getWebkitExitFullscreen();
if (exitFullScreen == null) {
exitFullScreen = getMozCancelFullScreen();
if (exitFullScreen == null) {
exitFullScreen = getMsExitFullscreen();
if (exitFullScreen == null) {
throw new UnsupportedOperationException();
}
}
}
}
exitFullScreen.justDoIt();
}
@JsFunction
interface ExitFullScreen {
void justDoIt();
}
@JsProperty(name = "exitFullScreen") private
native ExitFullScreen getExitFullScreen();
@JsProperty(name = "webkitExitFullscreen") private
native ExitFullScreen getWebkitExitFullscreen();
@JsProperty(name = "mozCancelFullScreen") private
native ExitFullScreen getMozCancelFullScreen();
@JsProperty(name = "msExitFullscreen") private
native ExitFullScreen getMsExitFullscreen();

Have a look at https://github.com/gwtproject/gwt/issues/9327
I'd do it like:
@JsOverlay
public void exitFullScreen() {
if (getExitFullScreen() != null) {
nativeExitFullScreen();
} else if (getMozCancelFullScreen() != null) {
mozCancelFullScreen();
} else if (getWebkitExitFullscreen() != null) {
webkitExitFullscreen();
} else if (getMsExitFullscreen() != null) {
msExitFullscreen();
} else {
throw new UnsupportedOperationException();
}
}
@JsMethod(name = "exitFullScreen") private native void
nativeExitFullScreen();
@JsProperty(name = "exitFullScreen") private native Object
getExitFullScreen();
@JsMethod private native void webkitExitFullscreen();
@JsProperty(name = "webkitExitFullscreen") private native Object
getWebkitExitFullscreen();
@JsMethod private native void mozCancelFullScreen();
@JsProperty(name = "mozCancelFullScreen") private native Object
getMozCancelFullScreen();
@JsMethod private native void msExitFullscreen();
@JsProperty(name = "msExitFullscreen") private native Object
getMsExitFullscreen();
It's a bit verbose in the method declarations (but the idea of JsInterop is
that this could be somehow
generated; https://developer.mozilla.org/en-US/docs/Web/API/Fullscreen_API
has the info in wiki format, there probably is a machine-readable format
somewhere, from Closure externs
<https://github.com/google/closure-compiler/blob/cf3c1f5ba45d3154c80ce5eecbec45549e8641f6/externs/browser/html5.js#L3125-L3213>
or DefinitelyTyped; an equivalence table like in the MDN wiki could even
allow generating that @JsOverlay method),
but the if-cascade is otherwise the same as the original JSNI method.

jsinterop with browser-specific api
Hi all. I'm trying to understand how can I effective work with jsinterop
and browser-specific api.
For example Fullscreen api is mostly work in latest browsers, but methods
are prefixed.
Before jsinterop I was write something like this:
public static native void leaveFullscreen() /*-{
if ($doc.cancelFullscreen) {
$doc.cancelFullscreen();
} else if ($doc.mozCancelFullScreen) {
$doc.mozCancelFullScreen();
} else if ($doc.webkitCancelFullScreen) {
$doc.webkitCancelFullScreen();
}
}-*/;
What should I do now? Add mozCancelFullScreen, webkitCancelFullScreen
methods to my jsinteropped Document interface? And then add static jsni
method
boolean exists(Object a)/*-{return a;}-*/; and add java method with "if
(exists(..))" chain.
It looks very verbose and inefficiently.
