+
+This editor is provided by a class named wxStyledTextCtrl.  As
+the name suggests, you can define styles that can be applied to
+sections of text.  This will typically be used for things like
+syntax highlighting code editors, but I'm sure that there are other
+applications as well.  A style is a combination of font, point size,
+forground and background colours.  The editor can handle
+proportional fonts just as easily as monospaced fonts, and various
+styles can use different sized fonts.
+
+There are a few canned language lexers and colourizers included,
+(see the next demo) or you can handle the colourization yourself.
+If you do you can simply register an event handler and the editor
+will let you know when the visible portion of the text needs
+styling.
+
+wxStyledTextEditor also supports setting markers in the margin...
+
+
+
+
+...and indicators within the text.  You can use these for whatever
+you want in your application.  Cut, Copy, Paste, Drag and Drop of
+text works, as well as virtually unlimited Undo and Redo
+capabilities, (right click to try it out.)
