Associating color-table with widget application [message #8754]

The problem is simple: in a widget application, I want the widget to
load its own color-table whenever the cursor is "in" the application,
and load a pre-existing color-table when the cursor is "out" of the
application. Sounds easy right? Please tell me it is...what keyword
did I miss this time?

I tried using tracking events, but you get color-flashing whenever
you leave one widget and enter another, even if you enable tracking
events for ALL widgets. If you enable tracking events for only the
TLB, you lose your colors whenever you move into, say, a slider
widget which adjust a plot which you really need to see in the
correct colors...

Then I saw the KBRD_FOCUS_EVENTS keyword to the WIDGET_BASE()
function, and I thought I was quite clever. But of course you
lose your colors again when, say, you press a slider widget that
adjusts a plot which you really need to see in the correct colors...

This seems so basic. It's easy to do for, say, a draw widget. But
how do you do it for an entire widget heirarchy? RTFM's welcome!
