2011-05-16 moel.mich Fixed Issue 215.
2011-05-15 moel.mich Improved the selection dragging on the tree view. The selection moves now only when the dragging starts on the tree view. With the old implementation, double-clicking the gadget would change the selection, because the mouse is still pressed when the main window is shown.
2011-05-15 moel.mich Added some GUI improvements: Better handling of the row selection, minimal row spacing of 18 pixel (to get nice dotted lines) and 3 decimal digits for voltages. Also changed the tree view font rendering to get better quality without ClearType.
