Clock Control Data Tag Constants |
Header: ControlDefinitions.h |

Data type returned or set: LongDateRec structure
You can use the control data tag constants to set or obtain data that is associated with a control. The control data tag constants are passed in the inTagName parameters of SetControlData and GetControlData to specify the piece of data in a control that you wish to set or get. You can also pass these constants in the inTagName parameter of GetControlDataSize if you wish to determine the size of variable-length control data. These constants can also be used by custom control definition functions that return the feature bit kControlSupportsDataAccess in response to a kControlMsgGetFeatures message.
The data that your application sets or obtains can be of various types, dependent upon the control. Therefore, the descriptions of the control data tag constants list the data types for the information that you can set in the inData parameter to the SetControlData function and that you can get in the inBuffer parameter to the GetControlData function.
The control data tag constants are available with Appearance Manager 1.0 and later.
