# An example of embedding CEF browser in the Kivy framework.
# The browser is embedded using off-screen rendering mode.
# Tested using Kivy 1.7.2 stable on Ubuntu 12.04 64-bit.
# In this example kivy-lang is used to declare the layout which
# contains two buttons (back, forward) and the browser view.
# The official CEF Python binaries come with tcmalloc hook
# disabled. But if you've built custom binaries and kept tcmalloc
# hook enabled, then be aware that in such case it is required
# for the cefpython module to be the very first import in
# python scripts. See Issue 73 in the CEF Python Issue Tracker
# for more details.

# This is just a temporary fix, until proper Popup widgets

# there is no way to obtain a native window handle (GtkWindow
# pointer) in Kivy, and this may cause things like context menus,
# select boxes and plugins not to display correctly. Although,
# this needs to be tested. The popup widget buffers are
# available in a separate paint buffer, so they could positioned
# freely so that it doesn't go out of the window. So the native
# window handle might not necessarily be required to make it work
# in most cases (99.9%). Though, this still needs testing to confirm.
