Text viewers

For each tier different screen representations of the tier's annotation data can be displayed.  The idea is that each user task has it's own special visualization and interaction demands. The user can open a set of text viewers that best meets his/her current task.

To make these viewers manageable they are at all times synchronized in a couple of ways:

1. They all show the current media time, both static (when media playback is stopped) and dynamic (media is playing). Jumping to some specific media time causes all text viewers to adjust their display.
2. They all show the currently selected media time interval (= selection). Selecting one annotation in one viewer shows the annotation's time interval in all other viewers.
3. They all show a cursor. The cursor points to one annotation on one tier. Future editing commands will apply to this cursor.

Subtitle viewer

On the page for the video window also subtitle viewers were displayed. For each tier such a viewer can be added to the video window. Each viewer shows a general panel for the tags of the tier. At each moment in time the panel is filled with the values for the tag that is present at that time. When playing media this has the effect of showing and hiding subtitles at proper times.

The complete window, video plus subtitle viewers, gives a kind of time slice representation of selected tiers.

The display order of the viewers can be changed simply by picking up a panel by it's edge and dragging it to the proper position.
