Emoji support

[Sikander Rafiq]

@Vadi2
Hi Vadi, Have you added support for emojis in qt application for windows. Have you added emoji support. It works well for colored emojis as well?. Please share how you implement it in qt application for windows.

Thanks.

[Vadi2]

No, I haven't. It's too complicated in Qt right now.

Have you implemented colored emojis properly in qt project in this way which you mentioned in this post?

You did not mentioned when we get uint by combining high and low surrogate and it is emoticons, then how to render it in qt.
Thanks in advance for your response.

as written i used Twitter emoticon icons (PNGs), so yes they are colored.

As i mentioned use QTextObjectInterface. Following the same principle like in this example.

I have developed Emoticon widget in Qt C++. Please see https://youtu.be/QXDfhien_vM

Here are some implementation hints:

@raven-worx I am trying to change your github project to build with CMake

https://github.com/raven-worx/qrwemoticons

I seems the steps you described above are not in this implementation, is that correct? Do you have any samples to share with those steps, or are they not really needed any more? Thanks
