WxGlade + PyGame...and making the two play together

[exodus]

As a fun little task to gain more knowledge of python, i decided to try to mimick the ipod UI with it. here's what i've got so far

everything works up to when it's time to play an mp3 file. as you can see, i have a TreeCtrl that lists the items in a folder. However, as you know, when you enter a new folder with an ipod it slides over to a new screen, so i had to have a go at that.. anyway, when it's time for pygame to play a song i get a seg fault (i expected as much).
what i'm trying to have the program do is...when it opens up that next frame (I haven't actually added the ipod-folder-slide effect yet..) and lists the contents and i click a file, i want pygame to play that file. the problem is that i have to idea how to tell pygame which file the user has selected...

all help would be greatly appreciated.

Right off the bat, I'd suggest a true subclass of wx.APP:

class MyApp(wx.App):
    def OnInit(self):
        self.main = frame_1(None)
        self.main.Show()
        self.SetTopWindow(self.main)
        return True
 
def main():
    application = MyApp(redirect=False) # or True depending...
    application.MainLoop()

I've noticed some differences in behavior between this an PySimpleApp.

Secondly, there's got to be a better module for playing MP3s than PyGame (unless you need other features of that package).

Can you tell us what you did differently? It's not totally obvious looking at the code.
Thanks.

hmm, i'll search around for a better module.

i'll try out what you suggested because after i got it to successfully play
[ here's what i did to get it to work:
once the directory is listed and displayed in the TreeCtrl, i use os.chdir('music'), then os.getcwd() (which would be /music) + "/" + filename; i then use pygaim to play that.

problem now is, when i try to open a frame and have pygaim play the song in that window i get a seg fault.

#edit..lol just noticed a little funnny string i used for debugging..whoops ^_^
here's where i'm at now..

I deduce from

item = os.getcwd() + "/" + item

that you are on an "other" OS (lol). So please tell us about your OS and platform.
Thanks.

[Smygis]

If you are on Linux you can use gstreamer.
In Debian/Ubuntu its:
python-gst0.10 - generic media-playing framework (Python bindings)
dont know about other distros, But i guess its something similar.
But something i think is nicer is MPD. The Music Playing Daemon (Realy geeky). Sorta easy to use. But the python bindings for it totaly sucks.

i don't know about being on an "other" OS ;)...Ubuntu is the only OS I have installed ^_^


I'll check into gstreamer, Smygis, thank you

"Other" refers to OSes who's path names that don't start C:\. Knowing which one you are using is required info if we are to give relevant suggestions/solutions.

[exodus]

taking all suggestions on how to pursue coding this ipod UI
ANY advice is very welcomed

i'm check out pygtk to see if i like it better than wx..

[bartonc]

i'll check out pygtk to see if i like it better than wx..

IMO, GTK is not as well structured as wx. We have on member on these boards who is required to use GTK and wishes he xould switch to wx. I've had a look at GTK's class structure and didn't see anything that I liked.

I also prefer Boa Constructor over wxGlade for GUI generation.

Just my two cents worth.
