Notifications with principle for mac. Hello, I was starting to play around the mac version of cefpython.Unfortunately, it seems that I reached the same problem listed inissue 163In that issue, the temporary solution is:The solution was to set the -localepak=Resources/en.lproj/locale.pak flag.I noticed that the Resource folder doesn't have the en-US data, just the en data. Is my cefpython binary is incomplete or am I missing something?I still can not get it working. The message in console like 'locale.filepath empty' or 'Locale could not be found for en-US' keep coming out.Can someone help me how to solve this problem temporarily until a fix has been confirmed.Thanksunk.@googlegroups.com19.03.15 02:44Czarek Tomczak.19.03.15 02:45. I just want to do it quickly but somehow missed all the little things.Just want to confirm that the Wx example now working, and after an intensive compare with my source and with the pyside modification, I realized that the switch parameter sent to the init method is wrong. The correct one is 'localepak' like in the example, but somehow I typed 'locale-pak'. The process didn't warn me about wrong param, so I did not notice it.Now, the Wx example is working fine and my PySide example doesn't show error like 'locale' 'en-US' anymore.Thank you.

Here is a little introduction to CEF Python's library off-screen rendering features. At the beginning I will explain what is CEF Python and what is off-screen rendering. Then I will show you a most basic example of CEF off-screen rendering - the screenshot.py example. At the end you will find a link to a tutorial that discusses the code in the example in details.Introductionis a GUI toolkit that lets you embed Chromium web browser in desktop applications.

This browser does not have any Back/Forward buttons or other visible controls that would identify it as a web browser (but there are a few examples that add such controls). CEF Python can run without depending on any third party GUI frameworks, but it can also be embedded in applications that use popular GUI toolkits such as: Qt, wxPython, GTK, Kivy and others.CEF Python also supports off-screen rendering mode which is used by the screenshot example that will be discussed here. Off-screen rendering, in short OSR, also known as windowless rendering, is a method of rendering pages into a memory buffer without creating an actual visible window. This method of rendering has its uses, some pluses and some minuses. Its main use is so that web page rendering can be integrated into apps that have its own rendering systems and they can display web browser contents only if they are provided a pixel buffer to draw. CEF Python provides a few examples of integrating CEF off-screen rendering with frameworks such as, and.CEF Python supports Python 2.7, 3.4, 3.5, 3.6 and Windows, Linux, and Mac platforms.The screenshot.py exampleThe is a basic example of off-screen rendering.

This example takes a screenshot of a web page, saves it in current directory as screenshot.png and then opens it with default application. With optional arguments to this script you can resize viewportso that screenshot includes whole page with height like 5000pxwhich would be an equivalent of scrolling down multiple pages.By default when no arguments are provided it will load cefpythonproject page on Github with height set to 5000px. Here is the result of running screenshot.py without arguments:Before running this script you have to install cefpython3 package and Pillow image library (PIL module): pip install cefpython357.0pip install PillowScript usage: python screenshot.pypython screenshot.py 1024 5000python screenshot.py 1024 768TutorialIf you would like to understand how the code in screenshot.py example works then take a look at the section in CEF Python's Tutorial which disccusses the code from the example in great details.Have fun!.
