Sending string msg from "browser" to "java" world

GoogleCodeExporter commented 9 years ago

This is more of query than a bug.

In javachromiumembedded, there is a provision to send msg to Java world.
By invoking "window.cefQuery", it is possible to send a string to Java world in 
the above library.

I was looking for such a thing in javacef. So far I couldn't.

I thought, its better to post a query.

1) Is it possible to send such string msgs ? (in the current implementation)
2) If yes,..please provide some pointers.
3) If no, any tips to build that bridge (c/c++ -> jni -> java)
    such as 1) fixing any c++ file
            2) porting to latest cef runtime
            etc..

This is important for me to adopt this library. Please help.

Regards,
Chandra

Currently javacef doesn't support this. The way to do this is different in 
newer version of cef. I'll have time to port the latest cef this weekend, and 
the method is in Issue 3.

For the latest runtime,
https://code.google.com/p/chromiumembedded/source/browse/trunk/cef3/tests/cefcli
ent/binding_test.h
https://code.google.com/p/chromiumembedded/source/browse/trunk/cef3/tests/cefcli
ent/binding_test.cpp
https://code.google.com/p/chromiumembedded/source/browse/trunk/cef3/tests/cefcli
ent/client_handler.cpp    (line 649)
https://code.google.com/p/javachromiumembedded/source/browse/trunk/src/native/me
ssage_router_handler.cpp

For the current (old) runtime:
https://code.google.com/p/chromiumembedded/source/browse/branches/1547/cef3/test
s/cefclient/binding_test.h
https://code.google.com/p/chromiumembedded/source/browse/branches/1547/cef3/test
s/cefclient/binding_test.cpp
https://code.google.com/p/chromiumembedded/source/browse/branches/1547/cef3/test
s/cefclient/res/binding.html

I think you can implement a similar one as binding_test, register it, send the 
string to Java, return a true/false in the Java method and call the success or 
failure method in c++.

Hi,
I am eagerly waiting about porting cef to the latest.
If you don't mind, can you give me approx dates by when this can be completed. 
I will plan my work accordingly.

Thank you.

Is there a any plan to support java to js / js to java communication ? I'm 
looking for something similar to org.eclipse.swt.browser.Browser.execute() and 
org.eclipse.swt.browser.BrowserFunction

@guillez, I don't have time to work on this now, so you may need to check the 
links of the latest runtime in comment #1 for js to java. You can add a native 
method to pass the string from java to c++ and call 
g_handler_local->GetBrowser()->GetMainFrame()->ExecuteJavaScript("js", 
frame->GetURL(), 0);
