Detailed Description

Abstract base class for SceneView Knob-specific methods.

Member Typedef Documentation

typedef void(* DD::Image::SceneView_KnobI::WidgetEventCallback) (CallbackReason, Knob *, WidgetEventCallbackParam &, const char *)

callback type passed from an op returns with the callback reason, the knob the callback was invoked for, plus two custom int and a const char* parameters.

CallbackReason - enumerated value giving the reason for the callback invocation

Parameters

Knob	- The knob invoking the callback
WidgetEventCallbackParam	- a vector of integer values giving context information for the callback. The values in this parameter are dependent upon the CallbackReason: eCustomMenuOptionSelected - The first element will be the index of the custom menu item selected. eItemNameChanged - The first element will be the index of the item that has changed eItemMoved - The first element will be the index that the selection is being moved to, The 2nd - n+1th elements are the indices of the n elements being moved (n can be obtained by the vector size()-1)
const	char* - a string giving context informtaion for the callback (can be NULL) The values in this parameter are dependent upon the CallbackReason: eCustomMenuOptionSelected - NULL eItemNameChanged - The new name of the item eItemMoved - NULL
