    <p>I am trying to write a small audio player in PyQt4. This is a part of the code I've written:</p> <pre><code>class Player(QMainWindow): def __init__(self, fileLoc, parent = None): super(QMainWindow, self).__init__() self.totTime = 0 self.audioOutput = Phonon.AudioOutput(Phonon.MusicCategory, self) self.mediaObject = Phonon.MediaObject(self) self.mediaObject.setTickInterval(1000) self.mediaObject.tick.connect(self.tick) self.mediaObject.stateChanged.connect(self.stateChanged) Phonon.createPath(self.mediaObject, self.audioOutput) #Define Play, Pause and Stop actions self.playAction = QAction(self.style().standardIcon(QStyle.SP_MediaPlay), "Play", self, enabled = False, triggered = self.mediaObject.play) self.pauseAction = QAction(self.style().standardIcon(QStyle.SP_MediaPause), "Pause", self, enabled = False, triggered = self.mediaObject.pause) self.stopAction = QAction(self.style().standardIcon(QStyle.SP_MediaStop), "Stop", self, enabled = False, triggered = self.mediaObject.stop) #Initiate User Interface self.userInterface() self.timeDisp.display('00:00') self.mediaObject.setCurrentSource(Phonon.MediaSource(fileLoc)) self.mediaObject.play() def tick(self, time): self.displayTime = QTime(0, (time / 60000) % 60, (time / 1000) % 60) self.timeDisp.display(self.displayTime.toString('mm:ss')) </code></pre> <p>My problem is, I am unable to figure out how to get the total duration of the file being currently played. I have tried printing the output of mediObject.totalTime() at the end of <strong>init</strong>(). But it returned -1 for all the videos. mediObject.totalTime() inside tick() is returning incorrect duration (10 - 15 seconds longer than the actual duration). </p> <p>Also, I may have to access the value of total duration from outside the class. How can I do this?</p> <p>Thanks in advance.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
