I'm having problems with widget_table. On a single character insertion
(event.type = 0), I believe the event.offset is not always correct. Run
the test procedure in the example code (below). It creates a
widget_table in a widget_base. Whenever a widget_table event is
generated, the program dumps (help,/struct) the event.
When you run it you'll notice the string 123 has been placed in the
upper left cell. Double-click on this cell to put it into edit mode
and move the insertion point to just after the 3. Press the 4 key.
Observe that the event.offset value is 2 for the character insertion
event (type=0). Shouldn't it be 3? Now, delete the 4 and move the
insertion point to between the 2 and 3. Press the 4 key. Note the
event.offset is 2. How the heck am I supposed to tell the difference
between the user inserting a character at these two locations????

Am I missing something or is this a bug?
