## Description

TOpenOptionsEx is a set type used to store zero (0) or more values from the TOpenOptionEx enumeration. It is the type used to implement the OptionsEx property in TOpenDialog, and contains the widgetset-specific options enabled for a dialog.

In the current implementation, TOpenOptionsEx contains values specific to Windows Vista or later versions. It contains values which cannot be mapped directly to values in the TOpenOption enumeration.

## Version info

Added in LCL version 4.0.
