I'm trying to add a clock UIType so that Myth themes can include a
clock in themed dialogs.
I'm doing this because I want a clock on the watch recordings screen,
so I'll know if I should watch another MythBusters, or go to sleep.

I created a subclass of UITextType called UITimeType. It runs a timer
that is correctly calling back to the UITimeType's animate method
every second. This method is correctly updating the text of the
UITimeType, and calling refresh();
The remaining problem is that the clock only updates on the screen
when I manually cause an overlapping UIType to refresh, for example,
by scrolling up/down in the recording list.
How can I force the UITimeType to update itself on the screen every
time its timer calls its animate() method?
Do I need to get ahold of the MythDialog and tell it to refresh the
bounds of my UITimeType, as the UIAnimatedImageType seems to do? If
so, how the heck is UIAnimatedImageType's m_window getting set?
Typically things are redrawn on the screen during an updateRect call.
You might want to look at the timer code in playbackbox that updates the
preview video. It runs on a timer and paints that part of the screen.
Typically the code calls the theme subsystem to get the Rect for a
particular UI element, then updates that as appropriate. Your Rect
could get updated in a timer that fires every second and then repaints
that part of the screen only.
