1 GetSelectedTrackEnvelope()

GetSelectedTrackEnvelope()

void* GetSelectedTrackEnvelope(ReaProject* proj)

Get the currently selected track envelope as an opaque pointer (can be passed to GetSetObjectState), returns 0 if no envelope is selected

Parameters

ReaProject* pro

Returns

void* a pointer to the currently selected track envelope

Examples

Perl

#
# Adds an envelope point at time=1 second, value=1.0
#
# This example shows the correct use of GetSelectedTrackEnvelope()
# but cannot be run as it also uses the obsolete function GetSetObjectState().
# GetSetObjectState() is no longer available and is being replaced 
# by object specific functions.
#
# The example will be re-written using the appropriate 
# GetSet function when it is available.
