The scrolling direction of a Ticker is language and localization dependant.
If the Ticker string consists of only white space,
it is not shown.
If setString() is called while the Ticker is visible, the Ticker restarts
with the new string.
If a Displayable has an active Ticker when a popup is activated, the Ticker is displayed
dimmed and active in the background.
The height of a Ticker may vary according
to the phone language selected by the user. Each time the Ticker string is updated, the Ticker height is adjusted, if necessary, to accommodate the text to be
displayed.
From Java
Runtime 2.1 for Symbian onwards, the text in the Ticker is cropped, if its length exceeds 8000 characters.
In earlier runtime and platform releases, if the text length exceeds
8000 characters, the behavior is unspecified.
