Waveform.Create method

Previous pageReturn to chapter overviewNext page



Creates an instance of the Waveform class: 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. For development environments like WPF, where controls don't expose a HWND, the usage of the Waveform.CreateNew method should be preferred.


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 class section.
