Mcow: New code sample

New code sample

New page

This is a Python script demonstrating the handling of MediaMonkey events from an external program.

It requires Python and the pywin32 package. This code was developed using Python 2.6; it should work for any Python 2.x (at least from 2.3 on), but may require changes for Python 3.

<source lang="python">
# monitor player events from MediaMonkey. print event flag and player state info for each
# note: once started, script does not exit until MM is shut down.
import win32com.client
import pythoncom
import time

boolReps = ['F', 'T'] # hacky!
quit = False

class MMEventHandlers():
def __init__(self):
self._play_events = 0

def showMM(self):
# note: MMEventHandlers instance includes all of SDBApplication members as well
playing = self.Player.isPlaying
paused = self.Player.isPaused
isong = self.Player.CurrentSongIndex
print 'Play', boolReps[playing], '; Pause', boolReps[paused], '; iSong', isong,
if playing:
print '>>', self.Player.CurrentSong.Title[:40]
else:
print

def OnShutdown(self): #OK
global quit
print '>>> SHUTDOWN >>> buh-bye'
quit = True
def OnPlay(self): #OK
self._play_events += 1
print "PLAY #",
self.showMM()
def OnPause(self): #OK
print "PAUS #",
self.showMM()

def OnStop(self):
print "STOP #",
self.showMM()
def OnTrackEnd(self):
print "TRKE #",
self.showMM()
def OnPlaybackEnd(self):
print "PLYE #",
self.showMM()
def OnCompletePlaybackEnd(self):
print "LSTE #",
self.showMM()
def OnSeek(self): #OK
print "SEEK #",
self.showMM()
def OnNowPlayingModified(self): #OK
print "LIST #",
self.showMM()

# OnTrackSkipped gets an argument
def OnTrackSkipped(self, track): #OK (only when playing)
print "SKIP #",
self.showMM()
# the type of any argument to an event is PyIDispatch
# here, use PyIDispatch.Invoke() to query the 'Title' attribute for printing
print '[', track.Invoke(3,0,2,True), ']'

def monitor():
# running the script will start MM if it's not already running
SDB = win32com.client.DispatchWithEvents('SongsDB.SDBApplication', MMEventHandlers)

print "** monitor started"
while not quit:
# required by this script because no other message loop running
# if the app has its message loop (i.e., has a Windows UI), then
# the events will arrive with no additional handling
pythoncom.PumpWaitingMessages()
time.sleep(0.2)

# note that SDB instance includes members of of the MMEventHandlers class
print "** monitor stopped; received " + str(SDB._play_events) + " play events"

if __name__ == '__main__':
monitor()
