Intellimouse panning (improved Auto-Panning Windows)

This article improves on the code submitted by Umut Alev, Auto-Panning Windows.

Ever since I saw the use of this Intellimouse control in the Infoviewer of DevStudio and later in Microsofts Internet Explorer, I've wanted an improved version that didn't strain the eyes and had much finer increments than 1-pixel, 2-pixels etc. Eudora Pro can use Microsofts viewer and since I read a number of newsletters, the scrolling is either too slow or too fast. I also wanted the panning to be simultanoeusly possible both vertically and horizontally.

Improvements made

  • Scroll simultaneously in horizontal and vertical directions. I added code to Umuts class to handle scrolling both vertically and horizontally at the same time (you can still have it the old way, it's a BOOL switch). The cursor does not change in this case, it remains the pointer in all four directions.
  • Scroll with much finer resolution (much smoother) by time and pixel dependant scrolling.
