Xevents it's a TurtleBlocks plugin for design different types of accessibility interfaces in an easy way for users that doesn't know about programming, using TurtleBlocks and different types of sensors

Actually a simple scrolling prototyped in this plugin is being ported to sugar[1], it means better speed because it's a Sugar service, and could be configured in Sugar control panel.

Speaking with X, using Xlib, it's possible use the plugin inside or outside Sugar in any GNU/Linux system with a GUI.

This is an example of a basic scrolling made with TurtleBots and Xevents

the task of this function is to change the X position of the line by the last mouse X position, and the Y position by the actual mouse position in Y + 3px, until arrives to the screen's border and then starts again. Then, when you press butia button again, the line stops, hides and makes a click in the mouse position.
