Where can we download all of the bitmaps for the buttons for it?

[Stefano Mtangoo]

I have attached the Icons. They are Tango Icons and are free to Download. Just extract to the folder with script following structure
folder\media_advanced.py
folder\icons

[lllllIllIlllI]

I have noticed that whenever i run it onSetPath() never seems to ever get run. Would this be a problem, or is it just me that this is happening to?

[Stefano Mtangoo]

Anyone got it working? It gives message that now playing but no sound! what is wrong? Have tried on XP and Vista, and will try on ubuntu.

[Stefano Mtangoo]

I think something might be wrong with Loading file and play it
Can someone explain how media ctrl loads file and plays it? May be from there I can find the bug and fix it!

[Freaky_Chris]

OK, here is my sugestion...please bare in mind i know nothing about Python GUI and event handling so i cannot really provide any sort of code examples.

You need to ensure that the media has loaded correctly before you can play it. So the best way to doing this is to play the sound inside the wx.media.EVT_MEDIA_LOADED event.

Hope that makes sense to you
Chris

[Stefano Mtangoo]

Yep Will take a look at that event!
Thanks Sir!

[Stefano Mtangoo]

can't see it in wxpy docs, any link or example?

[vegaseat]

Strange, in onCheck() I did a few testprints ...
print self.player.Load(path) --> True
print self.player.Play() --> False, should be True
print self.player.Length() --> 0, should be > 0

It seems to load the media file correctly.
Actually, when you load an .avi file and press stop the first frame shows.

In my own example code the media player works just fine on XP.

[Stefano Mtangoo]

Your own code? Can you post them? Have you noticed what is wrong??

[vegaseat]

As I read through my own code, I figured out your problem. You need to put a small delay in, so the file can be fully read before the player starts ...

[Stefano Mtangoo]

doesn't play file in my Machine!
Is something wrong with it?

[Freaky_Chris]

Make the delay bigger, thats the idea behind wx.media.MEDIA_LOADED event it triggers when the media is loaded and only then, unfortunately it seems poorly documented.

Chris

[Stefano Mtangoo]

Im working on this one:
http://docs.wxwidgets.org/stable/wx_wxmediaevent.html#wxmediaevent

[Stefano Mtangoo]

I at last solved it!
I added event to ListCtrl when the track get selected it calls setpath which calls oncheck which Loads the file. I have left onplay only for playing files

Thanks all for your contributions, I really appreciate!
Bugfixing is very challenging!
