How to realise the folder dialog?

[Anonymous]

Hi.
I would like to filter the “files of type” to only folders, not seeing any other types of files.

DG::FileDialog dlg(DG::FileDialog::OpenFolder);
	OpenFolderDialogObserver dialogObserver(&dlg);
	if (!dlg.Invoke()) {
		return;
	}

I implement the IncludeFile function in The OpenFolderDialogObserver .But the method is invalid.
Thanks.

Hi akomporday.

I implement the IncludeFile function in The OpenFolderDialogObserver.

But when the dialog is opened, I can still choose other types of files.

Actually I want to filter the “files of type” to only folders, not seeing any other types of files
