Detailed Description

Event structure.

QEvt represents events without parameters and serves as the base structure for derivation of events with parameters.

The following example illustrates how to add an event parameter by derivation of the QEvt structure. Please note that the QEvt member super_ is defined as the FIRST member of the derived struct.

typedef struct QCalcEvtTag {
    QEvent super;                                    /* derives from QEvent */
    uint8_t keyId;                               /* ID of the key depressed */
} QCalcEvt;
