1. ListView first column indent in win32lib
Hi,
It seems that win32lib forces an indent for the first column of data in a
listview object to allow for an icon to be displayed, even if one is not
required.
I believe it has been requested before that win32lib be modified to make this an
option, see this post from 2001
http://www.openeuphoria.org/cgi-bin/esearch.exu?thread=1&fromMonth=3&fromYear=6&toMonth=5&toYear=6&keywords=%22Win32Lib+hacks%22
I've checked and commenting out line 2412 in win32lib.ew v0.70.4 does prevent an
ident on the first column (at the cost of not being able to display an icon I
suspect).
Is there any chance of win32lib being enhanced to make this first column indent
optional?
Cheers,
Mark

I'll check whether having no icon to display has any undesirable side effect. If
it hasn't, then I'll probably add a custom LVS_EX_NOIMAGELIST style, so that no
image list is associated to the LV when the style is given to createEx().
Inn the meantime, you can always try to:
w32VOID=sendMessage(lv_id,LVM_SETIMAGELIST,LVSI_NORMAL,0)
w32VOID=sendMessage(lv_id,LVM_SETIMAGELIST,LVSI_SMALL,0)
However, I am not sure you can remove the white soace where the image would go,
since MSDN says the following about the LVS_REPORT style, which I waaume you are
using:
" The leftmost column is always left justified and contains the small icon and
label. Subsequent columns contain subitems as specified by the application. "

Hi Chris,
Thanks for the reply. I tried your suggestion but it didn't work. I assumed that
LVSI_NORMAL was a typo for LVSIL_NORMAL etc.. and so I tried...
w32VOID = sendMessage(ListView11,LVM_SETIMAGELIST,LVSIL_NORMAL,0)
w32VOID = sendMessage(ListView11,LVM_SETIMAGELIST,LVSIL_SMALL,0)
You are right I am using the REPORT style, but only because it was the default
that the IDE chose. I also tested the LIST style and it kept it's indent as well.
So I guess you are right, as per the MSDN docs, once the indent/offset is there
you're stuck with it.
Cheers,
Mark

If I can hack something like setting the 1st column to 1px wide and using
whatever formatting on the second column (which would pretend to be the 1st etc),
I'll put it in a demo. But I don't think I can directly hack this into win32lib,
unless I find some brilliant idea.
