FreezeDemo- textlist

Introduction

This driver opens up a MultiColumnTextList in a Frame. It is intended to show off the freezing functionality. Here are some usage notes:

1. If you move your mouse into the MCTL frame, the background darkens and it enters "frozen" mode.
2. If you leave your mouse still for 5 seconds, the MCTL "thaws" and updates until you move your mouse again.
3. The first table row changes it's numbers every 1/2 second no matter what state the IconList is in. This is to show repainting on individual icons can happen properly.
4. A new table is added every 4 seconds, and the THIRD table is removed every 4 seconds once there are > 6 tables. Now we can see how both add and remove item works in both frozen or thawed states:
   • removing while thawed: removes the table and shifts everything over as expected.
   • removing while frozen: creates a blank spot where the table was.
   • adding while thawed: adds the table on to the end.and displays the new it immediately.
   • adding while frozen: shows no change. (underneath of course it still adds to the IconList)
5. Note that after several tables have been removed during a frozen state, unfreezing will force all the gaps created to be filled.
6. Of course when the Demo removes a selected table, MCTL de-selects it.
