Waveform.Create method

Previous pageReturn to chapter overviewNext page

Remarks

 

Creates the Waveform object: once created, the Waveform will stay active until the termination of the container application: being a graphical object, the Waveform 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 Waveform.SetHwnd method.

 

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

 

For further details about using the embedded Waveform refer to the Waveform object section.

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