Syntax
Pascal

The control represents the edit component known from FileOpen or Save dialogs and can be used in those use cases.  

It can easily be linked with other components such as an ExplorerBrowser and a TJamFilterCombo to make up a custom opening dialog. The path that was selected by the user can be retrieved using the SelectedPath property. Note, that this file need not actually exist in the file-system (as is needed for save dialogs).
