Detailed Description

The QtxPathDialog class adds possibility to browse the file system with help of standard Open/Save dialog boxes or enter the file/directory path manually.

Default implementation provides only one "standard" file entry. Sometimes it is necessary to select several different files/directories from the same dialog box. In this case it is possible to derive from the QtxPathDialog class and use createFileEntry() method to add required number of file entries.
