TTween library for Delphi now free

I have asked for financial backing while creating libraries that people want and enjoy, and as promised they are released into open-source land afterwards.

HexLicense was open-sourced a while back, and this time it’s TTween library that is going back to the community.


You have probably noticed how mobile phone UI’s have smooth movements? like on iOS when you click “back” the whole display slides smoothly into view; or that elements move, grow and shrink using fancy, accelerated effects?

This type of animation is called tweening. And the TTween Library makes it super easy to do the same for your VCL applications.


Check out this Youtube video to see how you can make your VCL apps scale their controls more smoothly

You can fork the project here: https://bitbucket.org/cipher_diaz/ttween/src/master/

To install the system as ordinary components, just open the “Tweening.dproj” file and install as normal. Remember to add the directory to your libraries path!

Support the cause

If you like my articles and want to see more libraries and techniques, then consider donating to the project here: https://www.paypal.me/quartexNOR


Those that donate $50 or more automatically get access to the Quartex Web OS repositories, including full access to the QTX replacement RTL (for DWScript and Smart Mobile Studio).

Thank you for your support, projects like Amibian.js and the Quartex Web OS would not exist without my backers!

    Hi Jon, thank you for sharing your great work again, if you allow me a suggestion, please put the description of the project, as you did in this post, on the “readme.md” file of the project and commit. It is a lot nice to have a read me when looking at a project in a repository.

    seriously, I mean this post “https://jonlennartaasenden.wordpress.com/2013/08/29/embarcadero-blacklisting-again/” is very, very funny.
    You write “With friends like you … who needs enemas”

    “Never say never”. 🙂

    nowadays, Why don’t you post anything about SMS?

      Ha ha! Yeah thankfully an older administration that.

      Well, as you probably know I left the Smart Team last year. I still use Smart Mobile Studio on a daily basis – and im doing a full cloud OS using Smart — so its very much used.

      But, since im no longer on the Smart Team, there is a limit to how much time i allocate for it. At least until my new RTL, QTX, is done.

      But whenever you read the words “Amibian” or “Quartex Web OS” — remember that that project is done, 100%, in smart pascal! Including the new compiler cores 🙂
