I used the Hotspot XML for testing, because it has a listview. So I
popped it up through Immed with:
dlg "t:\hotspot\hotspot.xml", "hotspotsDialog"
I then made a copy of the control:
set w = mouse.window.control
Then I nuked all the columns:
w.columns(1).delete (I did this several times until all the columns were
removed).
Then I created a new column:
Set c = w.newcolumn
Added it's text:
c.header = "Blah1"
Inserted it:
c.insert 0
Then set its width to autosize:
c.width = -2
I repeated those last few steps until I had columns Blah1 to Blah4.
Then I added several new list items:
set i = w.newitem
i.text = "Something"
i.insert 99
I repeated that about six times. That gave me several listview items,
all with the text "something."
Then came the fun part. x represents column headers. y represents
listview items.
for x = 0 to 3 : for y = 1 to 6 : w.text(y, x) = "r" & y & "c" & x + 1 :
next : next
That populated every listview item in every column with the RyCx
coordinates, like:
Blah1 Blah2 Blah3 Blah4
r1c1 r1c2 r1c3 r1c4
r2c1 r2c2 r2c3 r2c4
r3c1 r3c2 r3c3 r3c4
r4c1 r4c2 r4c3 r4c4
r5c1 r5c2 r5c3 r5c4
r6c1 r6c2 r6c3 r6c4

Subject: Re: Best way to do dynamic listviews in a WE dialog?
Well, I guess we should all prepare to be surprised. You really can
loop how you want to create listview items. You can add however many
columns you want, however many listview items you want, and then loop
through the items and populate them with whatever you want. We just
tried this using Immed and a blank listview control, and it worked
fine. You'll want to set the column widths to -2 so they autosize, and
pay special attention to the order in which you add them -- that seems
to make a difference. But it does work.
Whodda thunk it?

Doug,
As long as you specify a width (explicitly or implicitly) for the
containing listview control, the control itself should take care of
sizing the column widths.
Also, you don't have to write your dynamic XML to a file before using
it. You can pass XML data directly to the Dialog method via a string.
Take a look at the simple dialogs and message box objects in the toolkit
for examples.
Regarding your last question, you would indeed be surprised if that
worked. So would we. Each listview item is it's own entity, so you can't
get there from here via your route.

I have occasion to create a scripted dialog containing a ListView
control which, depending on runtime circumstances, will either have no
column headers or will have an unknown number of columns with dynamic
names. By "dynamic," I mean they will change from one dialog creation
to another; they will not change while one dialog is showing.
This scenario obviously outrules xml specification of column headers.
My basic question, though, is how dynamic is WE's code for positioning
and sizing things, and when does it run?
Specifics:
If I don't say in xml that there will be column headers, then I create
them at runtime, will things look out of whack on screen?
Related: Would it be better to say in XML that there will be column
headers, then turn them off in code when necessary?
If spacing and sizing is worked out at dialog creation time, I'm
wondering if I should pull the crazy stunt of writing out a dynamic
xml file and then using that to open the dialog. I doubt this is
necessary, but since I won't know the column count or widths in
advance, who knows...
And one final question, though I bet I know the answer: Text items
and subitems look writeable, but I don't suppose this means I can
shortcut the normal red tape of inserting rows and columns a cell at a
time with Insert calls, and just fill listview.text(i,j) as a
two-dimensional array to populate the control? I'll be surprised if
that one works...
