Hello,
I've succeeded in embedding gecko 1.9 in a wxWidget window.
It is a very simple beginning.
However, when the "http;//developer.mozilla.org" is loaded, I can see
the noscript element :
<div id="noscript"><p>Some features of this site require JavaScript.</
p></div>.
That is to say, javascript is disabled. When I click on hyperlink, the
application crashes.
What is to be done to enable javascript ?
Is it necessary to handle a profile like the ".vendor / app /
profile.file " created by xulrunner ?
Thanks a lot,
Cyril.
