| # This implementation is a modified version of the example of | ||
| # embedding CEF Python browser using Tkinter toolkit. | ||
| # Reference https://github.com/cztomczak/cefpython/blob/master/examples/tkinter_.py | ||
| # | ||
| # NOTE: This example often crashes on Mac (Python 2.7, Tk 8.5/8.6) | ||
| # during initial app loading with such message: | ||
| # "Segmentation fault: 11". Reported as Issue #309. | ||
| # | ||
| # Tested configurations: | ||
| # - Tk 8.5 on Windows/Mac | ||
| # - Tk 8.6 on Linux | ||
| # - CEF Python v55.3+ | ||
| # | ||
| # Known issue on Linux: When typing url, mouse must be over url | ||
| # entry widget otherwise keyboard focus is lost (Issue #255 | ||
| # and Issue #284). | ||
