I must fill my list but I don't want to fill the first column, how can I write?

C++

for (int nTagli = 0; nTagli< 10; nTagli++)
	{
		m_list.InsertItem(nTagli, _T(""), -1);
		m_list.SetItemText(nTagli, 1, _T("ciao"));
		m_list.SetItemText(nTagli, 2, _T("ciao1"));
		m_list.SetItemText(nTagli, 3,_T("ciao2"));
		m_list.SetItemText(nTagli, 4, _T("ciao3"));
	}

In this way I must fill the first column with an empty space..but I don't want to fill list not at all

What I have tried:

I tried to write in the first column but I don't find the correct way.

Why do you need the item text to be null?

Member 14594285 11-Jan-24 6:22am

because I must draw in the first column and the first column must be empty

If you set the text to the null string as shown above it should work.

Member 14594285 11-Jan-24 9:12am

yes but there is an empty space and the first column isn't drawn correctly

Richard MacCutchan 11-Jan-24 9:40am

Of course there is an empty space, that is what you asked it for. You need to explain exactly what you are trying to do here. Also, if you wish to reply to a comment then please use the Reply button above the message. That way I get a notification that you replied.

ok..I want to fill my list from the second column, not from the first, is there a way?

Member 14594285 11-Jan-24 11:01am

I tried:

for (int nTag = 0; nTag< 10; nTag++)
{
m_list.InsertItem(nTag, NULL, -1);

m_list.SetItemText(nTag, 1, _T("ciao"));

m_list.SetItemText(nTag, 2, _T("ciao1"));

m_list.SetItemText(nTag, 3,_T("ciao2"));

m_list.SetItemText(nTag, 4, _T("ciao3"));
}
but in the first column I hve an empty space

Richard MacCutchan 11-Jan-24 11:07am

And as I already told you if you don't put text in the first column it will leave an empty space. And I ask again: what are you actually trying to do with this control?

Member 14594285 11-Jan-24 11:10am

I want to fill the CListCtrl from the second column and I want to draw in the first column, but I don't see the drawn in the first column because there is a white space, if I don't fill the CList I see the drawn in the first column.

You probably need to use the LVS_OWNERDRAWFIXED style which allows you to draw the item yourself. See
List-View Window Styles (CommCtrl.h) - Win32 apps | Microsoft Learn[^] and also this article: Using virtual lists[^].

I wrote:
m_list1.SetExtendedStyle(LVS_EX_GRIDLINES | LVS_EX_FLATSB | LVS_EX_FULLROWSELECT | LVS_EX_SUBITEMIMAGES | LVS_OWNERDRAWFIXED);

but my problem isn't solved

Well unless you explain the problem in proper detail there is nothing we can suggest.

Member 14594285 11-Jan-24 11:50am

the poblem is that I can't draw in the first column of my list if I write:

for (int nTag = 0; nTag< 10; nTag++)
{
m_list.InsertItem(nTag, NULL, -1);

m_list.SetItemText(nTag, 1, _T("ciao"));

m_list.SetItemText(nTag, 2, _T("ciao1"));

m_list.SetItemText(nTag, 3,_T("ciao2"));

m_list.SetItemText(nTag, 4, _T("ciao3"));
}

I want to fill the list from the second column

Richard MacCutchan 11-Jan-24 12:13pm

No, because you are not following the rules for an owner drawn List control.

Solution 3

Use must fill the first column to use the ListControl. Use some graphic or some white picture.
Else redesign your app and try some other solution like text outside of the ListControl to provide the extra information.

I recommend that you take a look at this article and especially the code : Another Report List Control[^].

That is an owner-drawn list control in MFC and I use this class all the time. It is quite good I think.

I used this class, but I see that there isn't a method to color header of the column

Member 14594285 12-Jan-24 9:04am

Thank you, very useful
