-This editor is provided by a class named wx.StyledTextCtrl. 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,
-foreground 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.
-
-wx.StyledTextEditor 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.)
