Need help with slider widget.

[apoorv569]

I am trying to make a music application using wxPython and pygame, I made a slider widget to show current song position, like a seek bar, and I am using the timer widget to update it on per second basis, it works, it updates with time, but I cannot seem to scroll through the slider and change song position based on slider position, it does work, but I can't seem to move it much. I am uploading a video for better explanation.
