95bfd958 18This editor is provided by a class named wx.StyledTextCtrl. As
f6bcfd97
BP
19the name suggests, you can define styles that can be applied to
20sections of text. This will typically be used for things like
21syntax highlighting code editors, but I'm sure that there are other
22applications as well. A style is a combination of font, point size,
8b9a4190 23foreground and background colours. The editor can handle
f6bcfd97
BP
24proportional fonts just as easily as monospaced fonts, and various
25styles can use different sized fonts.
26
27There are a few canned language lexers and colourizers included,
28(see the next demo) or you can handle the colourization yourself.
29If you do you can simply register an event handler and the editor
30will let you know when the visible portion of the text needs
31styling.
32
95bfd958 33wx.StyledTextEditor also supports setting markers in the margin...
f6bcfd97
BP
34
35
36
37
38...and indicators within the text. You can use these for whatever
39you want in your application. Cut, Copy, Paste, Drag and Drop of
40text works, as well as virtually unlimited Undo and Redo
41capabilities, (right click to try it out.)
