ApInfo_t

Data structure for information passed to PhAB callbacks and setup functions

Synopsis:

#include <Ap.h>

typedef struct {
    short           reason;
    PtWidget_t      *widget;
    } ApInfo_t;

Description:

This structure is used as the second argument to most functions generated by PhAB, including code callbacks and module-setup functions.

The possible values for reason are:

ABR_PRE_REALIZE

Pre-realize setup function

ABR_POST_REALIZE

Post-realize setup function

ABR_CODE

Code-type callback

ABR_DONE

Done-type callback

ABR_CANCEL

Cancel-type callback

The widget argument is a pointer to the widget that invoked the callback function. This is very useful in setup functions to determine which widget initiated the link callback.

Classification:
