A datatype holding textual data (textmodel) and a text widget (wxtextview) as demonstration. Textmodel does not depend on a specific gui-toolkit.
Project description
0. INTRO
Textmodel is a datatype which can hold textstrings together with format information. It is similar to GtkTextBuffer in functionality, but it is completely independent of a gui-toolkit.
Wxtextview is an example widget written for the wx toolkit. It has the basic functionality of a text editor. It is developed and tested mainly on windows, however it seems to work on linux and mac as well.
Textmodel and wxtextview are experimental. They are neither bug free nor stable. Wxtextview lacks the configurability which you might expect from a real text widget. Hack it to fit you needs.
With release 0.2 two demos were added which show the more advanced possibilities of textmodel:
- notebook.py:
A mathematica-like notebook interface for python
- math_demo.py:
A demonstration of typesetting mathematics
1. USAGE
Running the demos:
Just cd to the demo directory and execute the scripts. No installationis needed. External dependencies are wxpython (all demos) and matplotlib (notebook). The demos were tested on linux, windows and mac platforms.
$ cd demo/ $ python textmodel.py
Using textmodel:
from textmodel import TextModel, defaultstyle text = TextModel(u'Hello World!') # highlight the word "World" text.set_properties(6, 11, bgcolor = 'yellow') # query the color print text.get_style(0)['bgcolor'] # --> color of first character print text.get_style(10)['bgcolor'] # --> color of last character # defaultstyle is just a dict print defaultstyle # -> {'bgcolor': 'white', 'textcolor': 'black', 'fontsize': 10, 'selected': False} # you can change it defaultstyle.clear() defaultstyle['underline'] = False defaultstyle['italic'] = False # test: text = TextModel(u'Hello World!') text.set_properties(6, 11, underline = True) print text.get_style(10) # -> {'underline': True, 'italic': False}
Using the wxtextview-widget:
from textmodel import TextModel from wxtextview import WXTextView import wx app = wx.App() model = TextModel(u'Hello World!') model.set_properties(6, 11, fontsize=14) model.set_properties(6, 11, bgcolor='yellow') # display the texmodel in a view frame = wx.Frame(None) view = WXTextView(frame, -1) view.model = model frame.Show() # set cursor and selection view.cursor = 5 view.selection = 0, 5 # display the same textmodel in a second view frame2 = wx.Frame(None) view2 = WXTextView(frame2, -1) view2.model = model frame2.Show() app.MainLoop()
2. NOTES
Most python files contain tests and demos. For example:
$ cd textmodel/ $ python textmodel.py ######################## textmodel.py ######################## > test_00: remove w. simplify............................... ok > test_01: row, col......................................... ok > test_02: update linelengths bei insert.................... ok > test_03: TextModel........................................ ok ...
