NOTE: Currently not fully compatible with Windows 10 Creators Update (April 2017). Scrolling works but middle clicks are delayed, see issue #14

TrackballScroll

Allow scrolling with a trackball without scroll wheel by using a low level mouse hook.

Changes the behaviour of both X-Buttons (typically buttons 3 and 4) to

• Scrolling, i.e. vertical/horizontal mouse wheel events, when an X-Button is pressed and the trackball is moved vertically/horizontally
• Middle button click, when an X-Button is pressed and released without trackball movement

Requirements

• A trackball or mouse with X-Buttons
• A Microsoft Windows x64 operating system with .NET 4.5.2

This software has been tested with a Logitech Marble Trackball(tm) and Microsoft Windows 10.

Run the program

• Execute TrackballScroll.exe, no installation is necessary. A console window is displayed while the program is running, close it to disable the mouse hook.
• When using this program with a driver software that allows customization of the button behavior, make sure to set the X-Buttons to default behavior. E.g. with a Logitech Trackman Marble, make sure to set the buttons 3 and 4 to default button behaviour and not back/Universal Scroll.
• The lines scrolled per wheel event are determined by the Microsoft Windows mouse wheel settings.
