WebKit / WebEngine note ======================= You should be able to use both modules, even in the same EQL instance, and even if you compile both modules with different Qt versions. Example: - compile the :webkit module with Qt 5.5 - compile EQL with Qt 5.8, including the :webengine module Now you should be able to load both modules, and run the respective examples, all from within the same EQL executable (this worked for me). EQL WebKit examples =================== This enables any application to embed web content, which can be fully controlled from Lisp. Or, if you already know Common Lisp, and have some basic knowledge of Html/JavaScript, you can easily create a GUI, without learning much of Qt, and without relying on a web-server. A list of features: 1) full Lisp access to QtWebKit, see e.g. QWebElement in Qt Assistant; a simple example: document.getElementById("x") // JavaScript (|findFirstElement| (frame) "#x") ; Lisp (passing QWebElements between JavaScript and Lisp is just native) 2) JavaScript / Lisp bridge: call Lisp functions directly from Html/JS; see QWebInspector [Scripts] and [Console] for debugging and executing JS; (test your Lisp functions by directly calling them from the QWebInspector console) 3) embed your own custom QWidgets in Html (see "plugin-widget" example), as they integrate natively here (either written in EQL or Qt/C++, see QLOAD-C++) "Html Utils" ============ See directory "Tic-Tac-Toe/" for an example of a plain WebKit application, using only some simple convenience utility functions, defined in "Tic-Tac-Toe/h-utils.lisp".
