Oscilloscope.Create method

Oscilloscope.Create method

Remarks

Creates the Oscilloscope object: once created, the Oscilloscope will stay active until the termination of the container application: being a graphical object, the Oscilloscope needs to be associated to an existing window that will be used as a surface for the graphic rendering: this window can be changed at a later time through the Oscilloscope.SetHwnd method.

Once created, by default the Oscilloscope is still not visible: you must make a call to the Oscilloscope.Show method in order to display it.

Note that you can have a different Oscilloscope for each of the allocated players: for further details about using the embedded Oscilloscope refer to the Oscilloscope object section.

For details about using Visual Feedbacks refer to the How to use the embedded Visual Feedbacks section.
