Trackbars come in two styles: media position (seeking) and volume. They are created in the same way and have similar functions. For more details about trackbars, See the Trackbars section of the Skin Reference.
The Seek trackbar displays the current position of the current media content. The SeekThumb image changes location to match the media content position. For example, if the content is playing at the beginning of a track, the thumb image will be superimposed on the left end of the Seek trackbar image. If the content is nearly finished playing, the thumb image will be on the right side. The Seek thumb image moves horizontally.
The user can tap and drag on the Seek thumb image to change the current position within the content. For example, the user can tap and drag the thumb image to the center of the Seek trackbar, and the content will begin playing at the middle of the track.
The Volume trackbar displays the current volume that will be played through the speaker. The VolumeThumb image location matches the current volume level. For example, if the volume is all the way up, the thumb image will be superimposed on the right end of the Seek trackbar image. If the volume is turned all the way down, the thumb image will be on the left side. The Volume thumb image moves horizontally. The position of the Volume trackbar is not affected by the Mute button.
The user can tap and drag on the Volume thumb image to change the volume level. For example, the user can tap and drag the thumb image to the center of the Volume trackbar, and the sound output to the speaker will be 50 percent of full volume.
