When 'Play' is pressed, it turns to pause.
If song does not play (file not found or pmo/pmi error) the button should not
become 'pause' really.
It should remain as 'play'.
Perhaps good solution would be not to do as:
[from HandleControlMessage()]
if (oControlName == string("Play") && eMesg == CM_Pressed)
{
int iState = 0;
// get control state
m_pWindow->ControlIntValue(oControlName, false, iState);
if (iState == 0) // PLAY
{
// set button state to PAUSE
iState = 1;
m_pWindow->ControlIntValue(oControlName, true, iState);
m_pContext->target->AcceptEvent(new Event(CMD_Play));
m_bPlayShown = false;
}
else // PAUSE
{
// set button state to PLAY
iState = 0;
m_pWindow->ControlIntValue(oControlName, true, iState);
m_pContext->target->AcceptEvent(new Event(CMD_Pause));
m_bPlayShown = true;
}
return kError_NoErr;
}
but to remove the above button manipulations and leave button state
transitions to code that already is under AcceptEvent():
case INFO_Playing:
{
int iState = 1;
m_pWindow->ControlIntValue(string("Play"), true, iState);
m_bPlayShown = true;
break;
}
case INFO_Paused:
case INFO_Stopped:
{
int iState = 0;
m_pWindow->ControlIntValue(string("Play"), true, iState);
m_bPlayShown = true;
break;
}
case INFO_DoneOutputting:
other:
[from HandeControlMessage()]
if (oControlName == string("Stop") && eMesg == CM_Pressed)
{
int iState = 0;
m_pWindow->ControlIntValue(oControlName, true, iState);
m_pContext->target->AcceptEvent(new Event(CMD_Stop));
m_bPlayShown = true;
return kError_NoErr;
}
what does code for Stop button do? My guess is disable it, but
how do I know? I could not find where these transitons/states are
defined/documented... aarrgh.
