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 substracting ID_OPTION from the message ID.

Member Enumeration Documentation

anonymous enum

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