pvbrowser manual (c) pvbrowser 2008

The slot functions are contained in a header file included by "mask<X>". This are the functions you have to fill out in order to code your own logic. Many usefull slot functions will be listed within this documentation. These templates you may use to Copy&Paste predefined solutions into your own pvserver.

DATA will define your local data structure for your mask. This may be compared to the private data of a C++ class, although it is expressed in ANSI C.

slot<X> will handle the events that occur. Within slot<X> you may evaluate the names of the widgets, that are listed in the enum of mask<X>.
