Data structure for information passed to PhAB callbacks and setup functions
#include <Ap.h>
typedef struct {
short reason;
PtWidget_t *widget;
} ApInfo_t;
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.
