This class represents the file chooser dialog.
+ It pops up a file selector box (native for Windows and GTK2.4+).
+
+ The path and filename are distinct elements of a full file pathname.
+ If path is "", the current directory will be used. If filename is "", no default
+ filename will be supplied. The wildcard determines what files are displayed in the
+ file selector, and file extension supplies a type extension for the required filename.
+
+ @remarks
+ All implementations of the wxFileDialog provide a wildcard filter. Typing a filename
+ containing wildcards (*, ?) in the filename text item, and clicking on Ok, will
+ result in only those files matching the pattern being displayed.
+ The wildcard may be a specification for multiple types of file with a description
+ for each, such as:
+ "BMP and GIF files (*.bmp;*.gif)|*.bmp;*.gif|PNG files (*.png)|*.png"
+ It must be noted that wildcard support in the native Motif file dialog is quite
+ limited: only one alternative is supported, and it is displayed without the
+ descriptive test; "BMP files (*.bmp)|*.bmp" is displayed as "*.bmp", and both
+ "BMP files (*.bmp)|*.bmp|GIF files (*.gif)|*.gif" and "Image files|*.bmp;*.gif"
+ are errors.
