true/false or TRUE/FALSE to prepare for the new boolean type and constants being added to Python. Added code to wx.py to test for the existence of the new constants and to create suitable values if not present. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/branches/WX_2_4_BRANCH@19335 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775

|
|
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.)
