? ListCtrl col align won't work when col added later

[Alec S.]

Hi,

I've got a dialog with a list control. It's associated with a CListCtrl
and I insert a few columns in InitDialog. Everything is fine so far. But
later I add some more columns to the CListCtrl but those always end up
Left-Aligned, and I can't get them to use a different alignment even if I
hard code it in the call to InsertColumn.

What's wrong? How can I fix it?


Thanks a lot.

Hi Alec,

Thanks for posting in the community.

From your post, I understand that you cannot set a different alignment to a
ListCtrl while hard coding it in the call to InsertColumn.

I created a test MFC dialog project according to your description, and used
the following code to test the InsertColumn method, it works OK:
BOOL CPListCtrlDlg::OnInitDialog()
{
...
// TODO: Add extra initialization here
m_lst1.InsertColumn(0, "1st Info",LVCFMT_LEFT, 90);
m_lst1.InsertColumn(1, "2nd Info",LVCFMT_CENTER, 90);
m_lst1.InsertColumn(2, "3rd Info",LVCFMT_RIGHT, 90);
m_lst1.InsertItem(1, "Left, left");
m_lst1.InsertItem(2, "2nd row");
m_lst1.SetItemText(0, 1, "Center..");
m_lst1.SetItemText(0, 2, "Right..");
...
}

void CPListCtrlDlg::OnOK()
{
// TODO: Add extra validation here

m_lst1.InsertColumn(3, "4th Info",LVCFMT_CENTER, 75);
m_lst1.SetItemText(0, 3, "New..");
}

So I think to isolate the problem on your side, would you please to upload
a stand-alone sample project(.zip) to the newsgroup, if not inconvenience?


Thanks!

Hi Alec,

Thanks for posting in the community.

I have received your sample project and can repro the problem.

However, based on my experience, the leftmost column of a ListCtrl is the
main item to a row, which can contains the small icon and label, this
column has alway the Left alignment style, it will ignore the specifying of
the alignment. It is by design to this control.

Hi, you can do this by setting the column order after inserting the column
(often useful when using drag n drop columns). In your code:

void CtestView::OnBnClickedButton1()
{
// TODO: Add your control notification handler code here
m_List.InsertColumn(1, "new col. (r)", LVCFMT_RIGHT, 100);

LVCOLUMN cl;
cl.mask=LVCF_ORDER;
cl.iOrder=0;
m_List.SetColumn(1,&cl);

m_List.InsertItem(0, "abcdef");
m_List.SetItemText(0, 1, "abcdef");
m_List.SetItemText(0, 2, "abcdef");
}

Hope that helps.

I see. I tried it and it works like a charm.

Thanks to both of you, now I know why it does that, and how to work
around it. Great, now I can continue work on that app.

Thanks again!

Hi Alec,

What's the thing going about your program?

However, if the problem still persists, please upload a small sample
project to help me for further troubleshooting.

Thanks!
