Name
draw_circledraw_circleDrawCircleDrawCircle — Interactive drawing of a circle.
draw_circledraw_circleDrawCircleDrawCircleDrawCircle produces the parameter for a circle created interactive by
the user in the window.
To create a circle you have to press the mouse button at the location which is used
as the center of that circle. While keeping the mouse button pressed, the
RadiusRadiusRadiusRadiusradius's length can be modified through moving the mouse.
After another mouse click in the created circle center you can move it.
A clicking close to the circular arc you can modify the RadiusRadiusRadiusRadiusradius of
the circle.
Pressing the right mouse button terminates the procedure. On macOS
draw_circledraw_circleDrawCircleDrawCircleDrawCircle can also be terminated by pressing the escape key.
After terminating the procedure the circle is not visible in the window any longer.
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
