 | 
						|
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.)
