1. [WIN] ListView: what event is response to clicking on item? (& attn: Fabio)
I've looked through back postings, and I cannot figure out how to know when
an item in a ListView has been clicked on. I gather that "getLVSelected()"
should be used instead of getIndex. I've seen suggestions for modifying
Win32Lib to allow onChange to work, but that makes it not work for anyone
who doesn't have that modification.
I found Fabio Ramirez's "Listview Styles", (what a nice looking demo! It
should be included with Win32Lib.), and that helped to make a whole row be
selected, but I can't see how to know when an item has been clicked on.
BTW, Fabio,
in your tabbed version of "Listview Styles", it doesn't appear that the
TreeView section works as you probably intended, in that there's only one TV
displayed with info, though you made 9, and it may not have the number &
"sub-ordering" that you intended. If so, here's my fix, it lets all 9 be
filled with items, 3 main & 3 under each main:
integer tvSubItemNo-- prevents mains & subs getting mixed together
procedure FillTreeView(atom tvId)
for i = 1 to 3 do
tvItemNo = addTVItem( tvId, icon03, icon03,
sprint(tvId) & " Item " & sprint(i), 0 ) -- 0 makes mains
for j = 1 to 3 do
tvSubItemNo = addTVItem( tvId, icon03, icon03,
sprint(i) & ": " & sprint(j), tvItemNo ) -- puts sub with
correct main
end for
end for
end procedure

I can give you advice
TRY: onMouse[LV] = routine_id( "proc/func" )
and below is a procedure I might call once I have a listview item
Keep in mind, the below I use to populate a tabitem of data from
snippets of info that lies in a listview your case may be different.
procedure Loadtab(integer event, integer x, integer y, integer shift) -- load
info into tab
sequence index, junk
-- In Update Mode?
-- if update then -- if in update mode then allow LV Mouse to update Focused
tabitem.
-- if event = WM_LBUTTONDOWN then
-- end if
-- else
if event = WM_LBUTTONDOWN then
descindex = getLVCount(ListLV)
if descindex = 0 then
else
index = getLVSelected(ListLV)
if length(index) < 1 then
else
descindex = index[1]
setFocus(TabItem5)
MasterTab()
end if
end if
end if
The way you've been handing out advice I thought you were the Guru...hmm?
Just picking Dan......Just picking! I asked this question before...when
listviews
came about being by Matt Lewis.

3. Re: [WIN] ListView: what event is response to clicking on item? (& attn: Fabio)
It seems that the library doesn't implement this yet. The best you can do
for now (other than euman's suggestion) is to trap the WM_NOTIFY event for
the listview's parent window. Then extract the notification code and if it's
NM_CLICK and the control id in the message matches the Listview's id, you
can then use getLVSelected() etc...
If you like, I can play around to get the exact code you'd need.

Euman,
Thanks, I'll try onMouse, seems pretty obvious now that you suggest it (I'd
tried onClick and onChange & they didn't seem to work, & then I tried
onEvent, but couldn't figure out what kind of event message returns to test
on).

Aku also asked a similar question earlier too, but the only advice I saw was
to change Win32Lib.
As shouldn't be hard to discern, I'm about as far from being a "guru" as is
possible, I just try to help out whenever I can so as to show my
appreciation for the useful answers & advice I receive here when I ask
questions :)
I also figure if I can answer a question or provide a code snippet, that
might save the really knowledgeable people some time that they could apply
to other questions, or possibly prompt people to answer a question in more
detail or better, or make a better code sample then I did.

Thanks Derek,
I'll try Euman's first, then if necessary yours. When you say trap the
WM_NOTIFY event, do you meant test for that in an onEvent?

I know for a fact my method works pretty well. I have an entire Family History
program written useing the listview that populates tabitems per item selected.
I can help you out further if you need me to, just let me know.

7. Re: [WIN] ListView: what event is response to clicking on item? (& attn: Fabio)
Euman,
Ok, it seemed to work ok for me except that each click on an item in the LV
gets the *previously* selected item, so I have to click twice on an item to
get it to work right. Here's what I did, is there something wrong with it?
procedure onMouse_ListView2(integer event, integer x, integer y, integer
shift)
sequence index ,mleBuffer
index = {}
mleBuffer = {}
if event = WM_LBUTTONDOWN then
if getLVCount(ListView2) then
index = getLVSelected(ListView2)
-- on first click, sequence is empty because nothing was actually
selected "yet"?
if length(index) then
for n = 1 to length(eMessages[index[1]][4]) do
mleBuffer &= eMessages[index[1]][4][n] & CrLf
end for
setText(MleText3, mleBuffer)
end if
end if
end if
end procedure
onMouse[ListView2] = routine_id( "onMouse_ListView2" )

hmmm, looks like it might work but I didnt test it. I do have an idea though.
try changeing the mask something like what I have here and get back to me if
you still have the same problem.
atom lvMask
lvMask =
or_all({LVS_EX_FULLROWSELECT,LVS_EX_HEADERDRAGDROP,LVS_EX_GRIDLINES,LVS_EX_ONECLICKACTIVATE,
LVS_EX_TRACKSELECT })
constant ListLV = create(ListView, "", hWnd, 152, 0,480, 160,
or_all({LVS_REPORT,LVS_SHOWSELALWAYS}))
--> insert all headers -->
insertListViewColumn(ListLV,1,0,LVCFMT_LEFT,60,"Index",0)
object junk
junk = sendMessage( ListLV, LVM_SETBKCOLOR, 0, rgb(192,192,228))
junk = sendMessage( ListLV, LVM_SETEXTENDEDLISTVIEWSTYLE, lvMask, lvMask)
the junks are important so dont forget those either.

Now that I think about it, it could be how you are populating the Listview
also....

10. Re: [WIN] ListView: what event is response to clicking on item? (& attn: Fabio)
Euman,
Well, here's something funny that would suggest the way I'm populating the
LV shouldn't be the problem: I tried using
"if event = WM_LBUTTONUP then"
to make sure the selection action had enough time to occur (after button
down), and
1. it wouldn't work *at all* (no response), & I would think it should, and
then
2. DOUBLE CLICKING worked EXACTLY right, pulled out the right text from my
var & everything!
So, when I can get the program to know when an item has been clicked on, it
gets everything I would want it to, but the difficulty is getting it to know
when an item is clicked on; WM_LBUTTONDOWN responds to the *previously*
selected item, as if the down button is being sensed *before* the item has a
chance to be/show selected, so it gets the item that *is* selected, the
previous one; and
WM_LBUTTONUP doesn't get responded to at all in the normal sense, but
*does* get responded to if I *double click*, which shouldn't (?) be
happening. I checked the constant declarations for them, too, and they seem
to be right, at least as far as "Winconst.ew" says.

12. Re: [WIN] ListView: what event is response to clicking on item? (& attn: Fabio)
Euman,
Ok, that's interesting. If I wait for the pointing hand to make the resting
on item selected, and *then* click on that item, then everything works ok;
but if I "rush" it, and click too fast (ie, before the hand has done its
work and made the rested on item selected), then it still works as before,
getting the *previously* selected item. I would suspect your app would
probably do the same?
Is it the trackselect that makes the pointing hand select the rested on
item?

This is the answer to the slow selection
junk = sendMessage( ListView2, LVM_SETHOVERTIME, 0, 10)
You'll be a believer!

15. Re: [WIN] ListView: what event is response to clicking on item? (& attn: Fabio)
Matt,
I did find that LVN_ITEMCHANGED constant in "Winconst.ew", but couldn't
figure out how to use it.
I can use the "onEvent" thingy in a sort of "cut'n'paste" way, but don't
really understand it very well. (I'm guessing that's what's involved?)
At your convenience, could you explain more fully how to make use of
LVN_ITEMCHANGED ?
I've used Eumans suggestion, for listview selection tracking mouse
movements, and single click activation, but LVN_ITEMCHANGED is maybe closer
to how one might expect to use it, like "onChange" (or at least consistent
with how we get stuff from other lists).

You may try my version of win32lib - 0.55.4. It has onChange for
ListViews. You can get it at http://www.webpark.cz/stachon .
