// This class creates a file selection dialog. It contains a combo box  //
// to select the desired directory. A listview with the different       //
// files in the current directory and a combo box with which you can    //
// select a filter (on file extensions).                                //
// When creating a file dialog one passes a pointer to a TGFileInfo     //
// object. When the TGFileDialog ctor returns the selected file name    //
// can be found in the TGFileInfo::fFileName field. This string must    //
// be freed by the users.                                               //
