This email sent to site_archiver@lists.apple.com In what context is parameterChanged being called? That is, is this in response to an event in a custom parameter or on-screen control, or just a value change for one of the standard plug-in types?

The documentation states this is possible in a filter ( which my plugin is ). I have not been successful at retrieving the FxParameterSettingAPI. I have not actually been able to retrieve any of the parameter APIs successfully. Any ideas? Should this be possible? Parameter Interaction When a user changes a parameter control for an FxPlug plug-in, the host application calls the plug-in method -parameterChanged:. In response, the plug-in can change the state of other parameters. For example, if the value of a toggle button changes, the plug-in can hide or reveal other parameter controls, or change their values. Note: In FxPlug 1.0, the -parameterChanged: method is included in the FxFilter protocol, but not in the FxGenerator protocol. Generator plug-ins that need to respond to parameter changes can use custom parameter UI. © 2005 Apple Computer, Inc. All Rights Reserved. (Last updated: 2005-06-04) smime.p7s
