CListCtrl selection

Hello!
I am trying to set selection in list control ( CListCtrl derivative)
programmatically.
When user clicks on any place of the item (not only on the leftmost
column),program should select the item that was clicked.
I handle WM_LBUTTONDOWN message in CListCtrlEx (derived from CListCtrl):
{
...
UINT uFlags = 0;
int itemHit = HitTest(point,&uflags);
if(itemHit != -1)
{
LV_ITEM item;
item.mask = LVIF_STATE;
item.iItem = itemHit;
item.stateMask = LVIS_SELECTED;
item.state = 0xFFFF;
//I tried also this way -->> item.state = 1;
SetItem(&item);
}
}
itemHit is always right,but after executing these lines of code,nothing is
selected.
What's wrong in my code?
Thanks in advance.

Have you tried: =20
SetItemState(itemHit, LVIS_SELECTED, LVIS_SELECTED);

You should upgrade to MFC 4.2b by installing the patch. 4.2-flat
only works reliably against beta versions of certain operating
system components, and will cause you trouble sooner or later.

CListCtrlEx is probably a bad name for a class--you should expect
that MFC itself will use that name someday.

You should be using the state flag for the state member:
item.stateMask =3D LVIS_SELECTED;
item.state =3D LVIS_SELECTED;
Are you doing anything in response to NM_CLICK?

Try this,
if(itemHit !=3D -1)
{
LV_ITEM item;
item.mask =3D LVIF_STATE;
item.iItem =3D itemHit;
GetItem(&item);
item.stateMask |=3D LVIS_SELECTED;
item.state |=3D LVIS_SELECTED;
SetItem(&item);
}

You should change this line to
item.state =3D3D LVIS_SELECTED;
because stateMask holds the states you want to change and state holds the=
=3D
new value of this states. For example if stateMask is LVIS_SELECTED | LVI=
S=3D
_FOCUSED and state ist LVIS_SELECTED that means, that your item is select=
e=3D
d, but the focus is removed.

After changing an items state you should call Update( itemHit) to force t=
h=3D
e list control to redraw this item.

There are two reasons that I can think of:-
1)It _may_ be that you don't initialize item.iSubItem. Usually, it's set =
to 0.
2)The ListCtrl is not the active view or does not receive currently recei=
ve
focus. There are two ways to solve it:-
1)Add the style LVIS_SHOWSELALWAYS. Looks at the documentation on how th=
is
affect selection in your code. (Thanks to David Elliot, who pointed this =
out
earlier to me.)
2)SetFocus before begin selecting item (not sure whether this really hel=
ps
- don't bother putting it since the first method is fine).
One more, if what you want to accomplish is simple select an item, why do=
n't
you use the cleaner and simpler SetItemState. For example:-
SetItemState(itemHit, 0xffff, LVIS_SELECTED);
p/s: I'm quite lucky today. I was about to repost a question (was rejecte=
d
:) ) on almost exactly the same thing (selecting items programmatically i=
n
CListView), when I read your mail. I notice that you put 0xffff instead o=
f 1
in newState parameter (which solve my problem). Why is that..?

Hi Svetlana,
I'm amazed iItemHit is right. I want the same behaviour for my CListCtrl
and, as far as i remember, the hittest'ed point has to be on the leftmost
subitem.
Anyway, here's a code snippet from my apps :
void CMyList::OnClickList(NMHDR* pNMHDR, LRESULT* pResult) // NM_CLICK
reflected message
{
...
pt.x=3D4; // To be sure the point is on the leftmost subitem
int Index=3DHitTest(pt);
if (Index=3D=3D-1)
return;
=20
SetItemState(Index,LVIS_FOCUSED|LVIS_SELECTED,LVIS_FOCUSED|LVIS_SELECTED)=
;
}
Hope this helps.

I tried your code but it does not work: itemHit is always -1.
I wrote a piece of code for you:

void CListCtrlEx::OnLButtonDown( UINT nFlags, CPoint point )
{
// Use if (GetStyle() & LVS_REPORT) if want want it works for List mode A=

if ((GetStyle() & LVS_TYPEMASK) =3D=3D LVS_REPORT)
{
CRect theRect;
// Find the Rect around the label and force the point as =

it was clicked in this rect
GetItemRect(0, theRect, LVIR_LABEL);
point.x =3D theRect.left;
CListCtrl::OnLButtonDown( nFlags, point );
UINT uFlags =3D 0;
int itemHit =3D HitTest(point,&uFlags);
// Directly use SetItemState is better...
if(itemHit !=3D -1)
SetItemState(itemHit, LVIS_SELECTED | GetItemState(itemHit, 0xFFFF), 0=
xFFFF);
}
else
Default();
}
/////////////////////////////////////////////////////////////////////////=

CDialog::OnInitDialog();
// Just add 2 cols and 2 items in the List
CListCtrlEx* theList =3D new CListCtrlEx;

=09
LV_COLUMN theLVC;
theLVC.mask =3D LVCF_FMT | LVCF_SUBITEM | LVCF_TEXT | LVCF_WIDTH;
theLVC.fmt =3D LVCFMT_LEFT;
theLVC.cx =3D 100;

theLVC.iSubItem =3D 0;
theLVC.pszText =3D "Column 1";
theList->InsertColumn(0, &theLVC);
theLVC.iSubItem =3D 1;
theLVC.pszText =3D "Column 2";
theList->InsertColumn(1, &theLVC);
int theItem;
theItem =3D theList->InsertItem(0, "Item1");
theList->SetItem(theItem, 1, LVIF_TEXT, "SubItem", 0, 0, 0, 0);

// TODO: Add extra initialization here
=09
return TRUE; // return TRUE unless you set the focus to a control
}
By the way: this will not work for right button click and for Context Men=
us.
In the new common controls (ActiveX SDK) you can use the
LVS_EX_FULLROWSELECT style to do it...
Hope this helps...

If this is the same CListCtrlEx that is available from MSDN, then when
you first configure the control in the parent class, use the member
function
YourCListCtrlEx::SetFullRowSel(TRUE);
This will select a row (and paint it as selected) whenever the user
clicks anywhere on a row (provided you are using the CListCtrl in report
mode).

Hi,
I have a serious problem with CListCtrl. I have a list control
with items and subitems. When the user presses any alphabet, I would like to
take the selection to the item containing the pressed alphabet as the first
character. This is taken care of automatically by CListCtrl. But I would
like to get the index of the item. I tried capturing WM_KEYDOWN but I get
only the code of the key. I am not able to find any function in CListCtrl
similiar to GetCursel in CListBox. I tried doing it indirectly but to no
avail. Anybody know the solution, please help me.

Find *first* selected, retrieve column 0 text
const int index = m_ListCtrl.GetNextItem(-1, LVNI_SELECTED);
if(-1 != index)
return m_ListCtrl.GetItemText(index, 0);
else
return _T("");

I did something on these lines. I made the control owner-draw. Then,
when I added items to the control I put an index number in the ItemData
member. Then I made a handler for DrawItem (it is owner-draw) - this
handler is passed the value of ItemData (its part of the DRAWITEM
structure). That is how I knew which row was being selected.
I have a freeware source example of this at
http://www.voicenet.com/~pgerhart/_shware.html
Look for the app called GridList.
Hope this helped.

Maybe you need to trap WM_CHAR, not WM_KEYDOWN, for the list control. In
addition, if you call the CListCtrl version first, you should then be
able to find the current selection by using the sequence;
GetNextItem(-1, LVNI_SELECTED);
(Thanks to Mike B for pointing it out in his book!)
This should then do what you want.

You should catch the LVN_ITEMCHANGED message. You'll get one message for
the item that's become unselected, and one for the item that's newly
selected.

You can call CListCtrl::GetNextItem() with the LVNI_SELECTED flag.

Check the on-line help for the GetNextItem() function.
Use the LVNI_SELECTED flag, you should be able to do it.

This function is
int GetNextItem( int nItem, int nFlags );
if you want to find selected item in the single selection listcontrol,
then:
int index = list.GetNextItem(-1, LVNI_SELECTED);

-----From: "Alian Ltd."
--- Cut from the MFC CListCtrl Documentation. Title: =
CListCtrl::GetNextItem ---
int GetNextItem( int nItem, int nFlags ) const;
=20
Return Value
The index of the next item if successful, or -1 otherwise.
Parameters
nItem Index of the item to begin the searching with, or -1 to find the =
first item that matches the specified flags. The specified item itself =
is excluded from the search.
nFlags Geometric relation of the requested item to the specified item, =
and the state of the requested item. The geometric relation can be one =
of these values:
=B7 LVNI_ABOVE Searches for an item that is above the specified item.
=B7 LVNI_ALL Searches for a subsequent item by index (the default =
value).
=B7 LVNI_BELOW Searches for an item that is below the specified item.
=B7 LVNI_TOLEFT Searches for an item to the left of the specified =
item.
=B7 LVNI_TORIGHT Searches for an item to the right of the specified =
item.
The state can be zero, or it can be one or more of these values:
=B7 LVNI_DROPHILITED The item has the LVIS_DROPHILITED state flag set.
=B7 LVNI_FOCUSED The item has the LVIS_FOCUSED state flag set.
=B7 LVNI_HIDDEN The item has the LVIS_HIDDEN state flag set.
=B7 LVNI_MARKED The item has the LVIS_MARKED state flag set.
=B7 LVNI_SELECTED The item has the LVIS_SELECTED state flag set.
If an item does not have all of the specified state flags set, the =
search continues with the next item.
Remarks
Searches for a list view item that has the specified properties and that =
bears the specified relationship to a given item.
--- end of cut ---
Use either LVNI_FOCUSED (this is where the 'cursor' is), or =
LVNI_SELECTED (this is item, which is selected - be careful - there =
might be many selected items, if your CListCtrl allows multiple =
selection)
Wishing success !

If m_ListCtrl is your list control, you can use
int index = m_ListCtrl.GetNextItem(-1, LVNI_SELECTED);
to find the index of the selected item. index will be -1 if no items
are selected in the list.
There's an example of using this function in the ROWLIST sample,

You'd be better off handling LVN_KEYDOWN since that notification comes
from the list control.
You can handle LVN_ITEMCHANGED to find out when an item is becoming
selected, though you won't know if it's due to a mouse or keyboard action.
I'd try catching the LVN_KEYDOWN, giving it to the list to let it do its
thing, then doing listCtrl.GetNextItem(-1, LVIS_SELECTED) to find the
first selected item.

Hi Rams,
you can do this by handling the =LVN_ITEMCHANGED Message
void CYourList::OnItemchanged(NMHDR* pNMHDR, LRESULT* pResult)
{
NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
// TODO: Add your control notification handler code here
int selection;
if(pNMListView->uNewState & LVIS_SELECTED)
{
selection = pNMListView->iItem;
....
....
}
}
Hope this helps.

Cycle through the list checking the state of each item for LVIS_SELECTED
Keep a running index as you cycle through the list.

-----From: Harsh_Sharma@gw2k.com
Unfortunately you do not have any function like GetCurSel() in CListCtrl.
You have to iterate through each items in your ClistCtrl to find out the
selected item
Here is the code which will do this for you
int iItems = ListCtrl.GetItemCount();
int iIndex = 0;
while(iIndex < iItems)
{
if (ListCtrl.GetItemState(iIndex,LVIS_SELECTED) == LVIS_SELECTED)
{
// The current value of index is your slected Item index
}
}

The code below should do the trick. It will return all the selected
items one at a time.
int y = -1;
while ( (y = m_ListCtrl->GetNextItem (y, LVNI_SELECTED )) >=0 )
{
pItem->iItem = y; // The index of the selected item
m_ListCtrl->GetItem(pItem);

Hello
You can get the index of the first selected record like this.
CListCtrl& lcTheList;
int nStart = -1, nFirstSelected;
nFirstSelected = ::SendMessage((lcTheList), LVM_GETNEXTITEM, (WPARAM), nStart
,
MAKELPARAM((LVIS_SELECTED|LVNI_BELOW), 0);
This looks for the first selected record. You can use other values for nStart
to specify where you want the search to start from, other flags with or
instead of LVIS_SELECTED, and other search direction instead of LVNI_BELOW.
See the VC++ online help on LVM_GETNEXTITEM.
