Hi, all!
I have a listbox with a column of checkboxes
that indicates whether or not a row is selected.
I'm trying to implement a "Select All" menu item
that would make sure all the rows in the listbox
are selected.
Is it the rows themselves you want selected, the checkboxes or both?
Corrected Quote:
If I do something like
for every = FIRST to listbox.listCount-1
listbox.cellCheck(every, kColumnSelected) = TRUE
next // every cell
I am assuming that First = 0 and kColumnSelected is the column with
the checkboxes (as Integer).
I also added -1 to listbox.ListCount as it would otherwise cause a
OutOfBounds exception. Remember there is a Row 0 at all times even if
there isn't data in it so 0 to 5 is Listcount = 6 but the last row is 5.
in the menu handler, is any event fired? If so,
which one? I've looked in the online reference
and the printed reference manual, but I haven't
found an answer.
In the above code neither CellAction nor CellClicked is fired if in
code but will be if done with the mouse.
The checkboxes will all be set to true.
FYI. If the mouse is clicked outside the checkbox the CellClick event
will be fired. If the mouse is clicked inside the Checkbox the
CellClick event will be fired and then the CellAction event will be
fired.
I hope this helps but I made some assumptions from your variable
names which weren't fully explained.

PS. Here's the code I used in a menuhandler for EditSelectAll where
column 0 is the checkbox column.
-------------------------------------
Dim every, FIRST,kColumnSelected As Integer
First=0
kColumnSelected=0
for every = FIRST to ListBox1.listCount-1
listbox1.CellCheck(every, kColumnSelected) = TRUE
next
