76 | NOTE ON CONTROL ACTION PROCS |
||
77 | |||
78 | When using the TrackControl() call when tracking an indicator, the actionProc parameter |
||
79 | (type ControlActionUPP) should be replaced by a parameter of type DragGrayRgnUPP |
||
80 | (see Quickdraw.h). |
||
81 | |||
82 | If, however, you are using the live feedback variants of scroll bars or sliders, you |
||
83 | must pass a ControlActionUPP in when tracking the indicator as well. This functionality |
||
84 | is available in Appearance 1.0 or later. |
