| TRACKMAP.C |
|
|
| |
|
|
| This file contains the code that implements the "MPlayerTrackMap" control. |
|
|
| The control displays the list of tracks contained in the current medium, or |
|
|
| a time scale appropriate to the length of the medium, in such a way as to |
|
|
| serve as a scale for the scrollbar. |
