Graph cursors - behaviour when selected

[Dugald Bell]

I'm using Measurement Studio 1.01, LabWindows/CVI 5.5.1 on a Windows 98 PC.

I have a program using multiple graph cursors and GetGraphCursor( ) to allow
a user to see the x and y values of the cursor as the user positions the
cursor over a waveform.

The positioning needs to be very accurate, but unfortunately as soon as the
user clicks on a graph cursor, the cursor crosshairs become thicker
(presumably as an indication of the selected cursor). This stops the user
from positioning the cursor accurately.

Is there any way I can keep the graph cursor crosshairs permanently thin?

TIA

There isn't a way to change how a cursor is hilighted when it is selected. There is a workaround though. If you put your graph in a Track Mode of Plot & Cursor Events, then you will get an event for Cursor Mouse Down and Cursor Mouse Up when a user interacts with a cursor. With these events and the Mouse Move event on the plot area, you could manually move the cursor without using the built-in cursor moving options. Just set a flag with the CursorMouseDown event and set it back with the CursorMouseUp event. Then, in the MouseMove event, move the selected cursor programatically while the flag is set.

How do I generate graph cursor move events? I know that in the programmers toolbox, you may enable extended mouse events, but I can't seem to find how to enable graph cursor events. Thanks.
