Hi,
Ultimately, I want to call TEST_setJSCallBack of gecko C++(TESTManager.cpp)
from TESTManager.js for testing callback function. So, I tried to add two
interfaces in nsIDOMMozTESTManager.idl, and then, I called TEST_setJSCallback()
function in gecko js(TESTManager.js) such as below:
var com = Components.classes["@mozilla.org/testManager;1"]
.getService(Components.interfaces.nsIDOMMozTESTManager);
debug(com);
var ret = com.TEST_setJSCallBack(test111);
debug("SetJSCallBack = " + ret);
But, "ret" value is set by TEST_setJSCallBack function of gecko js, not c++
function.
Do you know what is wrong in my codes?
