On Windows this it is easy to set window title, as SetPopup has a windowName parameter. On Mac and Linux CEF doesn't support setting window title through CefWindowInfo. I've tried to use CEF views in hello_world.py example, however it didn't work on Linux. Reported issue on CEF Forum: http://www.magpcss.org/ceforum/viewtopic.php?f=6&t=15006 .

The solution for Mac and Linux is to call native Cocoa / X11 functions to set window title.
