This package provides a high level support for creating file selection dialogs by handling the signals internally.

function File_Selection_Dialog
(Title : Glib.UTF8_String := "Select File";
Default_Dir : String := "";
Dir_Only : Boolean := False;
Must_Exist : Boolean := False) return String
Open a file selection dialog and make it modal. Return when either the Cancel button is clicked or when a file is selected. Default_Dir is the directory to display in dialog initially. Note that it must end with a directory separator ('/' or '\', depending on your system). You can use GNAT.Os_Lib.Directory_Separator to get the correct value for your system. If Must_Exist is True, then the file (or directory if Dir_Only is True) must exist. If Dir_Only is True, then the dialog is modified so that the user can only choose a directory name, but not a file name. The value returned is the name of the file selected, or "" if none.
