Kivy - Open source Python library for rapid development of applications
that make use of innovative user interfaces, such as multi-touch apps.

A welding procedure specification (WPS) is a written document providing direction to the welder (or welding operator). It contains all the necessary parameters viz. Joints, base metals, filler metals, positions, preheat, PWHT, gas etc. (including ranges, if any) under which the welding process must be performed. The protagonists of the serial are an elite group of police officers belonging to the Crime Investigation Department of the police force, led by ACP Pradyuman played by the dynamic Shivaji Satam. While the stories are plausible, there is an emphasis on dramatic plotting. His prosperous television career included very popular detective serials such as Hello Inspector (1990) and Damini (Marathi) on DoorDarshan, Commander (1992) on Zee TV, and Teesra Dola (1998) on DD2; all these made Ramesh a very popular TV personality. He also appeared in Haddapaar, Bandini, Vikram Aur Betaal, Yugandhara.

Cross platform

Kivy runs on Linux, Windows, OS X, Android, iOS, and Raspberry Pi. You can run the same code on all supported platforms.

It can natively use most inputs, protocols and devices including WM_Touch, WM_Pen, Mac OS X Trackpad and Magic Mouse, Mtdev, Linux Kernel HID, TUIO. A multi-touch mouse simulator is included.

Business Friendly

Kivy is 100% free to use, under an MIT license (starting from 1.7.2) and LGPL 3 for the previous versions. The toolkit is professionally developed, backed and used. You can use it in a commercial product.

The framework is stable and has a well documented API, plus a programming guide to help you get started.

GPU Accelerated

The graphics engine is built over OpenGL ES 2, using a modern and fast graphics pipeline.

The toolkit comes with more than 20 widgets, all highly extensible. Many parts are written in C using Cython, and tested with regression tests.
