Properties
integerCrntThumbPos

these are all private

Functions and Procedures
Beg_End_Data(Integer Direction Integer NoSave)
augment to set last direction, find at end and trigger a scroll bar change
integerColumn_Button(integer iCol)
prompt and spin button messages for columns
Get/set Column_Button to FORM_BUTTON_NONE|FORM_BUTTON_PROMPT|FORM_BUTTON_SPIN|FORM_BUTTON_SPIN_WRAP
get/set Column_Minumum_position
get/set Column_Maximum_position

Construct_Object()
integerDEO_Control_Object()
Returns TRUE to indicate that this is a DEO control. This is used by
if you are within a DEO control message and should therefore
send a DEO message.
DoDisplayCheckBox(integer iItm integer bSt)
This can be called from with entry_display to display a
checkbox. This is used for non-data entry checkboxes (most
often in sel-lists).
Displays a checkbox for the item passed based on passed state.
Display different ckboxes for displayonly and not. This can be
sent to display a checkbox. If a developer wishes to use different
bitmaps, they can augment this message.
Establish_Find_Mode(Integer mode)
augment to keep track of find direction, used by scrollbar
Header_Mouse_Click(Integer iItem)
augmented to change ordering direction of pbHeaderTogglesDirection is set.
Only do this if the selected column is already the selected column, if not
forward, which will do the normal column change and new index thing, if needed.
Insert_Row(integer row#)
IntegerLoad_Page(Integer Row#)
augment to set scroll info (it is needed to set the thumb)
OnBeginningOfPanel()
augment to always force the first column to be visible. This will occur during a
panels clear or save. It makes sense to restore the column. If you do no want this
behavior just cancel it.
OnInitSpin()
Read_Next_Record()
augment to set findatend. We use this to position the scrollbar
set(integer row integer col)
augmented to check if number of rows changed so we can support dynamic
resizing of non-batch lists.
Set(integer hmMsg integer iCol integer iParam)
Create interface to more easily get at column options:
This allows the developer to easiy get at all of the {...}
items in a dbGrid or dbList.

Advanced Message:
This is used to get/set the column message for the passed message
number. Other public column messages use this.
When SET : Pass message number, column, Integer param to Set.
When GET : Pass message number, column and return Integer param

set(integer iCol integer iPos)
set(integer iNewTop integer iNewCurrent)
the DFBaseEntryList class has it's own special Set_Top_item message (as of 9.0) which does not
set current_item. When used for non-batch lists, we don't want the set_current_item and
that is why it was removed. This fixes a problem when scrolling down/up when the entire
grid is shifted horizontally to the right. When you scroll, the grid would shift to col 0.
However, with batch lists we want the normal set_top_item or we get other problems. So we
we modify the method here to make it do a normal top_item (ie. set current_item).
