Instance Method

startAction:

Informs the host application that the plug-in will begin accessing parameters.

Required.

Declaration

- (void)startAction:(id)sender;

Parameters

sender

The sender is either the custom NSView subclass which implements a custom control, or it is a class implementing the FxBaseEffect protocol which is updating or accessing its own parameters.

Discussion

It is important to note that plug-ins implementing the FxOnScreenControl protocol should not invoke the startAction: or endAction: methods as the host application is already aware that parameters are likely to change.
