Hello Moz, thanks for your answer
The code snippets i have posted are not very clear, sry for this. In
fact 'window' and 'nativeWindowHandle' are the same handles.
But maybe i have bigger problems than i thought. I compiled xulrunner in
Debug mode (shame on me that i havent done this before) and get the
following error when calling XRE_InitEmbedding():
* Call to xpconnect wrapped JSObject produced this error: *
[Exception... "Component returned failure code: 0x80570016
(NS_ERROR_XPC_GS_RETURNED_FAILURE) [nsIJSCID.getService]"
Now im not sure wether Gecko is properly initialized at all, maybe this
is the problem with the segfault when trying to create a msBaseWindow.
What i did so far:
I compiled xulrunner from source and execute my small sample application
inside the mozilla/obj-xulrunner/dist/bin directory (without make
install - ubuntu has some bugs in the xulrunner packages and i dont want
to mess up my firefox installation). For the xul directory and the app
directory i use the same absolute paths as the execution directory:
std::string appRuntimeDir("/home/schmelly/mozilla/obj-xulrunner/dist/bin");
std::string xulRuntimeDir("/home/schmelly/mozilla/obj-xulrunner/dist/bin");
nsCOMPtr< nsILocalFile > xulDir;
nsCOMPtr< nsILocalFile > appDir;
NS_NewNativeLocalFile(nsCString(xulRuntimeDir.c_str() ), PR_FALSE,
getter_AddRefs(xulDir ) );
S_NewNativeLocalFile(nsCString(appRuntimeDir.c_str() ), PR_FALSE,
getter_AddRefs(appDir ) );
XRE_InitEmbedding()(xulDir, appDir, nsnull, nsnull, 0);
Is this supposed to work at all? Am i missing additional dependencies or
configuration?
thanks in advance and best regards,
David
