Qt in Web Browser?
Do you mean some sort of plugin ? Or connecting to the application through tcp and have it rendered in a web browser ?
Just FYI, I looked at PHP-Qt (which stopped about 5 years ago), FireBreath (for cross-browser plugins), and many others. I've also looked at KDE and Cocos2d-x as alternatives or complementary to Qt. I've even looked at numerous other systems/tools/frameworks/IDEs.
I'm interested in the answers to the following questions:
Can apps be developed with Qt that run in web browsers (e.g., chrome, firefox, internet explorer and safari)?
If so, what are viable approaches that require "minimal" additional effort?
If browser apps can be developed with Qt, can one code base, with possibly some minor modifications, also be deployed to Android and iOS platforms?
IIRC there's a project called Vaudeville to render a Qt application on a html canvas that could be of interest to you
if you want to actively run the Qt application in the web-browser - meaning with the possibility of interaction - the browser has to execute the native code. Thus a browser plugin is necessary.
IIRC for the most browsers (Firefox, Chrome, ...) the netscape plugin interface needs to be implemented. For IE browsers a ActiveX control needs to be implemented and registered in the system (regsrv).
But i don't know whats the future of plug-in interfaces is anyway. Currently it seems that support for such plugins will be dropped sooner or later.
For example chrome drops netscape plugin support with new blink engine. Also microsoft removes it's activeX plugin capablities in IE browsers.
