Hi,
I am using the wxListCtrl in wxLC_REPORT|wxLC_VIRTUAL mode to insert
the data. Is there any way for me to assign some kind of hidden data
with each raw? (Which can be returned when mouse click event occur on a
raw)

Thanks,
Lloyd

You can define an objarr array,
then use it as usual in your click handler.
This is like I do in aUCBLogo's StackVars window:

//in the header:

wxArrayString namearr, valarr;
wxArrayPtrVoid objarr;

// in the implementation:

wxString StackVars::OnGetItemText(long item, long column) const
{
if (inupdate)
return wxEmptyString;
if (!column)
return namearr[item];
return valarr[item];
}

void StackVars::OnClick(wxListEvent &ev)
{
NodeP nd=NodeP(objarr[ev.GetIndex()]);
if (!nd)
return;
nd->setExpanded(!nd->expanded());
update();
}

Cheers,
Andreas

Thanks Andreas.

What I understood from your code is, when a mouse click event occurs it
gets the index of the currently selected item and it returns the data
from the Array (based on the index).

But my case is different! What I actually want is -

I have some column headers, and when the user clicks on the column
header I want to sort the list based on that column. In this case each
time the list is sorted, the index which returns will be changed for the
same data in the raw! (Because the raw position shuffles).

If it was not in wxLC_VIRTUAL mode I could have used
wxListCtrl::SetItemData() and wxListCtrl::GetItemData()


Any suggestions?

Thanks,
Lloyd

When you sort your column,
can't you just sort an array (while sorting your column),
which contains the row number?
You'd probably have to write some special sort function,
which simultanously sorts two things,
but it will work, I think.
Then you can access your objarr indirectly via your row array.

Cheers,
Andreas

It doesn't make much sense to do this. If you use wxLC_VIRTUAL mode you
already have the data shown in the control somewhere else, why don't you
just add whatever "hidden" data you have to the same place?
