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.

TnFOX adds an upcall mechanism whereby any number of FX::Generic::BoundFunctorV's may be attached to a data target which are upcalled when the value changes. This is particularly useful when combined with FX::FXDataTargetI for generating generic code not requiring subclassing FXObject (which is HARD in a template)
