11. Obtaining Input Rotation Matrix

12. Multiple Cursors Cursor[] sdgCursors = {Cursors.Arrow, Cursors.Hand}; String[] sdgText = {"Edward", "Saul"}; int[] sdgDegreeRotations = {-90, 0}; for (int i=0; i < sdgManager1.Mice.Count && i < 2; ++i) { sdgManager1.Mice[i].Cursor = sdgCursors[i]; sdgManager1.Mice[i].Text = sdgText[i]; sdgManager1.Mice[i].DegreeRotation = sdgDegreeRotations[i]; }

13. Why Existing Widgets are Problematic

14. SDG Widget Layer public class UserControl1 : SdgUserControl { //Designer generated code private void SdgMouseDown(object sender, SdgMouseEventArgs e) { if (e.ID > 0) this.BackColor = Color.Red; else this.BackColor = Color.Blue; }
