CListCtrl selection without focus

Environment: VC++ 4.2b, Win 95
I would like to have the user pick at least one entry in several list
controls. So it would be best if there were some feedback which items
were selected even in the list controls without the focus. Is it
necessary to implement Owner Draw for this? (Urk.)

You will get LVN_ITEMCHANGED notification on your CListCtrl controls or use
CListCtrl::GetItem and check the LVIS_SELECTED flag in the state field.

To have the selection shown in the ListCtrl while the control does not have
focus, you need to set the LVS_SHOWSELALWAYS flag in dwStyle paramater of
the CListCtrl::Create. I've check the VC++ wizard for the List control and
this is not one of the setable properties but it is available.

Add LVS_SHOWSELALWAYS to the options of the list control in your .rc file.
The list control will now always show its selection, even when it does not
have the focus.
btw. this this option is not offered via the properties pop-up box of
a list control when editing a dialog template so it has to manually
inserted into the .rc file, but the option is documented in the
list view control reference in books online. Does anyone know what the
reason for this is? was it plainly forgotten or deliberately left out?

Try using the ModifyStyle member function to set
the LVS_SHOWSELALWAYS style on your CListCtrl.

You have to use the LVS_SHOWSELALWAYS flag with your list controls.
Unfortunately, Developer Studio does not allow to set this flag
directly, so you have to add it manually to your *.rc file:
[...]
CONTROL "List1",IDC_OBJ_LIST,"SysListView32",LVS_REPORT |
LVS_SINGLESEL | LVS_SHOWSELALWAYS | LVS_NOLABELWRAP
LVS_AUTOARRANGE | LVS_OWNERDRAWFIXED | WS_VISIBLE
....

Hi Andrew,
No need for an ownerdrawed CListCtrl to keep the
selection ( even if the focus is removed ).
Open your .RC in Text-Mode and set LVS_SHOWSELALWAYS
for your ListCtrl. (Must have been forgotten in the Properties-Dialog)
Best regardz
Sven

Answer: no, it's not necessary.
Just use the additional style LVS_SHOWSELALWAYS when creating your
CListCtrl objects.
But for nearly every other reasonable feature for list controls you
*have to* owner draw the controls items (e.g. showing the selection on a
whole row, drawing grid lines, ...)
MS has promised to provide such additional features to be shipped with
the Internet Explorer 4.0, but who knows when that will be?

Thomas Scholz

Thank you to the 4 people who sent this (Katy Mulvey was first).
Just so you-all don't think I'm an idiot, this flag is not
mentioned in the printed docs. (It is online.)
