Constants and Data Types

Picker Icon Structure

A color picker responds to the kGetIconData request code by returning its script code and the resource ID of its icon family. The Color Picker Manager needs this information to display the color picker in the More Choices list. The color picker returns this information in a picker icon data (PickerIconData) structure.

typedef struct PickerIconData {
   short    scriptCode;    /* script code */
   short    iconSuiteID;   /* resource ID for icon family */
   ResType  helpResType;   /* resource type for help balloon */
   short    helpResID;     /* resource ID for help balloon */
} PickerIconData;
