    ControlAnimations

    Library for Windows Forms that provides basic animations like WPF.

    (Published under MIT license, see source for details) ControlAnimations is an easy-to-use library for .NET Windows Forms that allows you to give any Control an animation for any property. It's flexible and easy-to-use, it uses cubic ease in-out interpolation for very smooth transitions. You can transition any property of any Control (panels, buttons, textboxes) either in color or in value. HOW TO USE After importing Digaly.ControlAnimations, you use it as follows: 1. Define a global variable in the Form class that will hold the animations: (C#) Animator anims = new Animator(); 2. In Form load (you could also do it elsewhere), add the animations: anims.Add("myanimation", panel1.MakeAnimation("Width", 100)); 3. Play the animation, for example in panel1.clicked event: anims.Toggle("myanimation") Your panel is now animated! Have fun! If you have any problems/concerns, please contact me.

    Ooui Web Framework

    Ooui Web Framework

    UI library that brings the simplicity of native UI development to web

    Ooui (pronounced weee!) is a small cross-platform UI library for .NET that uses web technologies. It presents a classic object-oriented UI API that controls a dumb browser. With Ooui, you get the full power of your favorite .NET programming language plus the ability to interact with your app using any device. Make sure to add a reference to Ooui before you start running! With just code, a web server that serves the HTML and web socket logic necessary for an interactive button will start. Ooui has been broken up into several packages to increase the variety of ways that it can be used. When the user requests a page, the page will connect to the server using a web socket. This socket is used to keep the server's in-memory model of the UI (the one you work with as a programmer) in sync with the actual UI shown to the user in their browser. This is done using a simple messaging protocol with JSON packets.
