/** 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:
|
|
- Sets the rotation angle to the numeric field in mouse operations.
|
|
- Shows the value entered/modified in the numeric field.
|
|
- Enables/disables/shows/hides the field according to own state changes.
