SingleSelListView with custom icons appearing as gray boxes

I'm having an issue putting custom icons into SingleSelListView rows. No matter how I assign the icon to the row, it always appears as a gray box.

I define a listview in the GRC file like this:

/* [ 2] */ SingleSelListView 40 60 370 350 LargePlain 40 40 150 50 singleColumn

then am trying to add the icons via code. I have tried this multiple ways.

Here is the code I'm using to setup the list view. The list view appears perfectly in the UI, except the icon's appear as grey boxes.

DGListViewSetItemSize(dialogID, listID, 150, 50); DGListViewSetImageSize(dialogID, listID, 24, 24); DGListViewDeleteItem(dialogID, listID, DG_ALL_ITEMS); //this code is inside a loop DGListViewInsertItem(dialogID, listID, DG_LIST_BOTTOM); DGListViewSetItemText(dialogID, listID, DG_LIST_BOTTOM, text); //icon set here DG::Icon aicon = DG::Icon(ACAPI_GetOwnResModule(), DG::Icon::GetIdFromString("35011")) DGListViewSetItemImage(dialogID, listID, DG_LIST_BOTTOM, DG_LVIT_ICON, aicon); //set status and userdata DGListViewSetItemStatus(dialogID, listID, DG_LIST_BOTTOM, DG_IS_ENABLE); DGListViewSetItemUserData(dialogID, listID, DG_LIST_BOTTOM, userData); //endloop

I have also tried this way of initializing icons and assigning them:

NewDisplay::NativeImage archimg(ACAPI_GetOwnResModule(), 35011, NewDisplay::NativeImage::Encoding::PNG); const void* dgPicture = GX::Image(archimg).ToDGPicture(); DGListViewSetItemImage(dialogID, listID, DG_LIST_BOTTOM, DG_LVIT_ICON, DG::Icon(dgPicture));

My final attempt, I added the icons as a DG::IconItems to my ModalDialog, displayed them somewhere so I knew they were working correctly, then did a .SetVisibility(false) and a .Hide() on the icons to not show them. I then did:

aIcon.SetIcon(DG::Icon(ACAPI_GetOwnResModule(), 35011)); //aIcon is an IconItem ... ... DGListViewSetItemImage(dialogID, listID, DG_LIST_BOTTOM, DG_LVIT_ICON, aIcon.GetIcon()); DG::Icon ai = aIcon.GetIcon(); bool empty = ai.IsEmpty(); //this is false bool valid = ai.IsValid(); //this is true

Despite all 3 of these methods, the icon in each row always displays as a grey box. I have tried using DG_LVIT_PICTURE and that didn't work either.

Does anyone have any suggestions, or has anyone encountered this before? Can I only use the default icons specified by Archicad?

The icon identifier variable must have "short" type. Your are passing 35011 that is outside of the short range in C++. Try using a number that is lower than 32767.
