TFilterComboBox.Mask Property

Specifies the mask associated with the string selected in the filter combo box.

Pascal

property Mask: string;

C++

__property AnsiString Mask;

Description

Read Mask to obtain the mask that was selected by the user.

When the user uses the filter combo box to select a new filter, the mask associated with the selected file type becomes the value of the Mask property. If a file list box is linked to the filter combo box with the FileList property, the file list will update when the value of Mask changes.
