cefclient | Custom cef client for tilemill windows | Runtime Evironment library

I would like to intercept key presses in CEF, so I can actually implement a few key shortcuts.

I've read in the CEF API docs [1] that in order to listen to KeyPress events it's necessary to implement the interface, or inherit from, ClientKeyHandler. Then overwrite two methods: OnKeyEvent and OnPreKeyEvent. The latter is called before a keypress has reached the user interface.

In any case, I proceeded to change my CEF based browser and overwrite these two methods. Changes are available on this branch [2] (built of top of CefProject).

Once I launch the browser and press whatever keys, I don't see any stderr/stdout output in the console. It seems these methods are never called, which make me wonder whether my understanding on how this is supposed to work is correct.

This is what I've tried so far:

I have started implementing JCEF in a project of mine, and I am initializing the embedded browser in a JInternalFrame inside of a JFrame, alongside a series of form fields on a JPanel next to the JInternalFrame. The browser component doesn't fully initialize until the JFrame actually becomes visible, and I'm finding that my JTextFields are uneditable unless the JFrame loses and regains focus.

Any idea of what could be happening and how to fix it? This only happens when using a JInternalFrame with the JCEF component...

It also happens every time I call loadURL to load a new page in the browser: the JTextFields become uneditable again, until I lose/gain focus in the JFrame.

UPDATE: I have found a hack which allows the JTextFields to become editable again, but I wouldn't call it a solution because it is not very elegant. I added a load handler to the CefClient instance ( client.addLoadHandler(new CefLoadHandlerAdapter()) ) with an @Ovveride on the onLoadingStateChange method, which in turn gives access to the current browser component. From there I can detect when loading in the browser is complete, and use SwingUtilities to get the Window that the browser component is in. Then I setVisible(false) and setVisible(true) on that Window. I say it's not a solution because every time the browser is done loading the Window disappears and reappears. Even though the JTextFields are editable again, it is quite ugly to see the window flashing. I've tried all kinds of revalidate() and repaint() methods to no avail, unless I didn't call them right...

there. I'm new to CEFbrowser. I'm developing the download model of My CefBrowser. I've written some code but error while compiling.

Try use CEF from C++. Make simple project:
