I'm doing software that controls my computer with a wireless navigator that includes Windows CE. I'm doing this with Python.
Okay, so lets begin. One of those control options is audio volume controlling. I have a code, that can change Windows XP WaveOut volume on a scale of 0-255. I want to make a horizontal bar so user can change computers volume over network. I have a function SetVolume(new_volume) that takes a argument called new volume. How can I make a horizontal bar what controls the volume? That bar should be like this:
0 |---------------------*----------| 255
The volume control is fixed in point *. For example like in Windows Media Player, or that tray icon, but it must be horizontal and on a scale of 0-255.
That image can help to understand. The red line should be movable with mouse. When the red line moves so it will need to pass a value between 0-255, depending on the point where it is.
PS. Sorry for my bad english. I'm not from a country where people speak english. I hope you understand.
