I have a piece of GWT code that I wanted to invoke from outside handwritten
JavaScript. There's an example shown here under "Calling a Java method from
Handwritten JavaScript":
https://developers.google.com/web-toolkit/doc/latest/DevGuideCodingBasicsJSNI
That example uses a static method; I can make that work, but my first
instinct was that i'd rather use an instance, so using the syntax shown
under JSNI invocations, I tried:
/* package */ native void exportJavascriptMethods( PreviewPane x ) /*-{
$wnd.imageSelected =
$entry(this
@ca.cpp.spike.gwtapplet.client.PreviewPane::imageSelected
(Ljava/lang/String;Ljava/lang/String;));
}-*/;
That doesn't work. Eclipse (and the GWT compiler) complain:
"JavaScript parsing: Missing ) after argument list PreviewPane.java"
If I replace 'this' with 'x', same problem. If I take 'this' out and leave
it binding to the static method:
/* package */ native void exportJavascriptMethods( PreviewPane x ) /*-{
$wnd.imageSelected =
$entry(@ca.cpp.spike.gwtapplet.client.PreviewPane::imageSelected
(Ljava/lang/String;Ljava/lang/String;));
}-*/;
All is well in the world.
So -- is that just not an option, exporting an instance method like that?
