Ryan,
You can use entry labels to both read and display data using the
"-textvariable" option. This is also accessable through the
attribute editor.
if you have an entry like this:
entry .e -textvariable time_data
you can change the entry display by setting the variable:
set time_data [exec date]
If you then type into the entry box, it will change the value
of time_data. You can avoid this by either using a label or
setting the -state on the entry to disabled.
