Declaration

function CheckAllFiles: Boolean; virtual

Function result

Description

CheckAllFiles is a Boolean function used to validate values in the FileName and Files properties using the Options enabled for the dialog.

FileName is checked when a non-empty string value has been assigned to the property, or when ofAllowMultiSelect has been omitted from the Options property. The lines of text in the Files property are validated when ofAllowMultiSelect has been included in the Options property.

CheckAllFiles calls the CheckFile method to validate and potentially update a file name. A file name modified in CheckFile to include a file extension is stored in the origin property (FileName or Files).

The return value is True if the file name(s) meet the requirements for the Options property and the local file system.
