1. RE: listview items colors
Hi Tone & all,
There has been many requests for this feature, but there has never been
any thorough explanation on how to do it. This would be a valued
addition to win32lib. Perhaps when the current issues are sorted out
Derek or someone may be able to move this further up the todo list.

Hey,
These are the only routines Im aware of.
junk = sendMessage(id,LVM_SETBKCOLOR, 0, color)
junk = sendMessage(id,LVM_SETTEXTBKCOLOR, 0, color)
junk = sendMessage(id,LVM_SETTEXTCOLOR, 0, color)
substitute color for your rgb( ) and youre set.

I certainly don't know how to implement this but so I understand, are
you saying that you would have to draw the entire LV yourself?
I'd like to see it called something like this:
addLVItem(MyLV, MyIcon, {data1, data2, data3},{color1, color2, color3})
and
addLVItem(MyLV, MyIcon, {data1, data2, data3},default)
etc. I think you'll get the idea.
Just my 2c.
Thanks

Thanks Tone.
There is a bug. It is in the defineUserProperty routine. Replace the
lines...
-- If not, then add it a new property.
if lPropIdx = 0 then
window_tag[pControl][tagPropId] =
append(window_tag[pControl][tagPropId], pPropId)
window_tag[pControl][tagPropInit] =
append(window_tag[pControl][tagPropId], pData) -- BUG
window_tag[pControl][tagPropData] =
append(window_tag[pControl][tagPropId], pData) -- BUG
with...
-- If not, then add it a new property.
if lPropIdx = 0 then
window_tag[pControl][tagPropId] =
append(window_tag[pControl][tagPropId], pPropId)
window_tag[pControl][tagPropInit] =
append(window_tag[pControl][tagPropInit], pData)
window_tag[pControl][tagPropData] =
append(window_tag[pControl][tagPropData], pData)
My mistake was caused by copying a line of code twice and only changing one
element reference in each of the two copied lines. This is a common mistake
with using append() etc...

Tone,
your demo works great now that the defineUserProperty bug is fixed. I'll
merge it into the main stream library . Great work!
