Hi,
Now I am trying to use xpcom for callback function.
But I couldn't call gecko c++ function from gecko js using the XPCOM.
My test codes are below.
In gecko js (TESTManager.js), I try to call "TEST_setJSCallBack" function but
it did not be called.
I don't know why gecko c++ function can't be called from gecko js.
Please check my sample code and find my mistake or something.
Please anybody help me.
Thanks.
