Cannot setupt image for the header of listctrl

[Z.J. Da]

Hi all,

I am using Iuri's GfxListCtrl in a formview, but cannot display images in its column headers. What I have found is that SetItem of CListCtrl is sucessful only for the first column then fails for all other columns. I have tried following code:
for(idx = 0; idx < 5; idx++ )
{
iChkIdx = pList->InsertColumn(idx, "");
pList->wndHeader.GetItem(iChkIdx, &hditem );
pList->wndHeader.SetItem(iChkIdx, &hditem );
}

SetItem returns 1 only when idx = 0 but GetItem returns 1 for all idx. Actually these functions are from CListCtrl (not GfxListCtrl). Because it fails to setup data, the header images are not drawn.

Has anyone any idea? Thank in advance!

If I am not wrong, you want to display images in the column headers. I did it for a CListCtrl in a dialog box. Create and set an image list for the listctrl.



m_ImageList.Create(IDB_MYICON,16,1,RGB(255, 255, 255));
m_listctrl.SetImageList(&m_ImageList,LVSIL_SMALL);





Add columns, items and subitems whichever way you want to. Then add the following code



LV_COLUMN lvc;
CImageList* pImageList;
for(int i=0; i<3; i++)//Max no of col = 3
{

// Set column mask
lvc.mask = LVCF_FMT | LVCF_SUBITEM | LVCF_WIDTH;

// Get column info
m_listctrl.GetColumn(i, &lvc);

// Set image for the column mask
lvc.mask |= LVCF_IMAGE ;
lvc.fmt |= LVCFMT_IMAGE | LVCFMT_LEFT;
pImageList = m_listctrl.GetImageList(LVSIL_SMALL);

// Set image index
lvc.iImage = i;

// Finally set the column with image
m_listctrl.SetColumn(i, &lvc);





I did this in OnInitDialog(). You can decide where you want to add images to the headers.

Hope this helps you.

Cheers!!!!
