Type: Specifies the type of data the control edits. Choose from Folders, Files, Network Servers and Strings.
Reset button: The control should display a button allowing the user to reset it to its defaults.
Options button: The control should display a button allowing the user to configure it.
Allow duplicates: Duplicate entries are allowed if this is turned on.
Drag-and-drop: The control supports drag-and-drop.
Edit as text: The control provides a checkbox letting it be switched into a mode where it can be edited in text form.
Read-only: Disables built-in editing functions. In this mode, clicking an entry button sends a "click" notification rather than editing it.
Notify delete: Causes delete buttons to be displayed for each item even in read only mode, and clicking a delete button sends a "delete" notification to the script's message loop.
Name filter: Prevents the user entering characters that aren't allowed in filenames.
The remaining flags control which items the control allows the user to add; most are type-specific.
