Hello,

I'm trying to get wxListView to display large (32x32) icons on multiple columns. I managed to get it to display one column but I don't know how to add more.

This is what I have so far:

Code: Select all

wxListView* listView = new wxListView(this, wxID_ANY, wxDefaultPosition, wxDefaultSize, wxLC_ICON);

wxImageList* imageList = new wxImageList(32, 32);

for (int i = 0; i < 4; i++) {
  wxIcon* icon = IconGetter::GetExecutableIcon(_T("c:\\windows\\system32\\shell32.dll"), 32, i);
  int imageIndex = imageList->Add(*icon);
  
  wxListItem* item = new wxListItem();
  item->SetText(_T("text"));
  item->SetImage(imageIndex);
  listView->InsertItem(*item);
}

listView->SetImageList(imageList, wxIMAGE_LIST_NORMAL);

So it works well except that it displays everything on only one column. I would expect it to shows the icons on one row then wrap when it reaches the end of line, and keep displaying the icons on the next row (like the "Tiles" view on Explorer). Is it possible to do that?

Thank you,

Laurent

So this is what I'm getting at the moment:

and this is what I'd like to have:

Any suggestions? Can it be done at all?

you probably have to use wxListCtrl directly and not wxListView. Check the "listctrl" sample.

Ok I've just figured out what was wrong. I was assigning the image list after having created the items; however it apparently has to be done before otherwise it just doesn't work properly.

So the right order is:

1. Create the image list
2. Assign it the list the view
3. Create the list items

This is how I've changed my code and now it's working:

Code: Select all

wxListView* listView = new wxListView(this, wxID_ANY, wxDefaultPosition, wxDefaultSize, wxLC_ICON);

wxImageList* imageList = new wxImageList(32, 32);

for (int i = 0; true; i++) {
  wxIcon* icon = IconGetter::GetExecutableIcon(_T("c:\\windows\\system32\\shell32.dll"), 32, i);
  if (!icon) break;
  imageList->Add(*icon);
}

listView->AssignImageList(imageList, wxIMAGE_LIST_NORMAL);

for (int i = 0; i < imageList->GetImageCount(); i++) {
  listView->InsertItem(i, _T("text"), i);
}
