Hi,
a have problem with EvtEventAvail.
I read data from serial port and have Form with Cancel button open.
I want to cancel the reading, when the button is pressed.
I test, if there is an event using EvtEventAvail.
If it is a perform SysHandleEvent and possibly FrmHandleEvent.
Code for the progress function follows.
It works OK on POSE. At real device (m515), it seems, that there is ALWAYS
some event (event.eType == 2)
(Seems like penUp).
How should I solve this problem?
Rudla
static Err CheckReadProgress(UInt32 bytes_to_now) /*
Purpose:
Serial port PortReadData progress function.
Returns cancel, if the user pushed some button.
*/{
UInt16 event_limit;
UInt8 buffer[100];
EventType event;
StrPrintF(buffer, "S:%ld", bytes_to_now);
WinDrawChars(buffer, StrLen(buffer), 0,12);
event_limit = 5;
while (event_limit-- > 0 && EvtEventAvail()) {
EvtGetEvent(&event, evtWaitForever);
ReportSubmessageInt("Event: %ld", event.eType);
if (event.eType == ctlSelectEvent) {
return ErrUserCancel;
}
if (!SysHandleEvent(&event)) {
FrmDispatchEvent(&event);
}
}
return 0;
}
