Dmitry Shtatnov / Mbed 2 deprecated TFT_320QVT_Window_Drag_Demo

mbed Window Dragging demo for TFT-320QVT module with SSD1289 and XPT2046 touchscreen. copyright GNU Public License, v2. or later Creates a window, which can be dragged within the screen, and can be closed with the standard WIndows-style "x"-button. Window appearance: initial position, size and colors can be changed via defines. Window in this demo can not be moved beyond the screen area except of the right side. May require a touchscreen calibration procedure using UTouchCD.h Made by Dmitry Shtatnov, SSSR Labs http://modularsynth.ru/
