Detailed Description

This control allows to input a rotation angle, visualized by a dial.

Usage: A single click sets a rotation angle rounded to steps of 15 degrees. Dragging with the left mouse button sets an exact rotation angle. Pressing the ESCAPE key during mouse drag cancels the operation and restores the old state of the control.

It is possible to link a numeric field to this control using the function SetLinkedField(). The DialControl will take full control of this numeric field:
