This uses the normal file selection dialog, but allows you to select multiple items. The second, better way to do things would be to create a tree control. The FileBrowse.hs sample shows you how to create a tree control, but you will need to make some changes to allow multiple selections. Firstly you will need to call wxTreeCtrl_Create with wxTR_EXTENDED in the style field, instead of using treeCtrl. Secondly, you will need to modify the event handling for onTreeEvent to properly handle multiple selection and deselection but modifying the handling of TreeSelChanged. I hope this helps you to move forward. Regards Jeremy
