|
|
|
|
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.)
