switch WEBLIB missing

I wonder how to use this function because WEBLIB is not defined.
If I uncomment the switch it works.

procedure TTMSFNCBitmapContainer.AddFromURL(URL, BitmapName: string);
{.$IFDEF WEBLIB}
var
bmpi: TTMSFNCBitmapItem;
{.$ENDIF}
begin
{.$IFDEF WEBLIB}
bmpi := Self.Items.Add;
bmpi.Bitmap.LoadFromURL(URL);
bmpi.Name := BitmapName;
{.$ENDIF}
end;

This is because the AddFromURL is only working for a TMS WEB Core application. If you want to download images from an URL inside an FMX application, please use the TTMSFNCURLBitmapContainer instead.

Works. I have to load the urlImages in the moment I expand the tree. But the tree does not show the bitmap unless I click somewhere on the tree. Do I have to call a kind of update?

The TTMSFNCURLBitmapContainer OnDownloadComplete event can be used to repaint the treeview

I tried already tree.repaint but has no effect.

Can you try

TMSFNCTreeView1.BeginUpdate;
TMSFNCTreeView1.EndUpdate;

I found this workaround.

Instead of

BitmapContainer.AddFromURL(imgName, aPath);

I have to give space before the bitmap is actually loaded.

bmpi := BitmapContainer.Items.Add;
bmpi.Bitmap.SetSize(fsize);
bmpi.Bitmap.Clear(TAlphaColorRec.null);
bmpi.Bitmap.LoadFromURL(imgCmd);
bmpi.Name := imgName;

Maybe the sizing of the node is not done after bitmap "arrives".

This is because once the treeview is initialized, the bitmap size is set. You can reset the node structure with ClearNodeList.

TMSFNCTreeView1.BeginUpdate;
TMSFNCTreeView1.ClearNodeList;
TMSFNCTreeView1.EndUpdate;
