Detailed Description

A Data Target allows a valuator widget such as a Slider or Text Field to be directly connected with a variable in the program.

Whenever the valuator control changes, the variable connected through the data target is automatically updated; conversely, whenever the program changes a variable, all the connected valuator widgets will be updated to reflect this new value on the display. Data Targets also allow connecting Radio Buttons, Menu Commands, and so on to a variable. In this case, the new value of the connected variable is computed by subtracting ID_OPTION from the message ID. A Data Target may be subclassed to handle additional, user-defined data types; to this end, the message handlers return 1 if the type is one of DT_VOID...DT_STRING and 0 otherwise. Thus subclasses can handle any data types not dealt with in the default implementation.

Member Enumeration Documentation

anonymous enum

Enumerator:

ID_OPTION	Will cause the FXDataTarget to ask sender for value.
ID_LAST	ID_OPTION+i will set the value to i where -10000<=i<=10000.
