textmodel 0.3

A datatype holding textual data (textmodel) and a text widget (wxtextview) as demonstration. Textmodel does not depend on a specific gui-toolkit.

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 your 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 installation is needed. External dependencies are wxpython (all demos) and matplotlib (notebook). The demos were tested on linux, windows and mac platforms.

$ cd demo/
$ python demo1.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 10th character

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()
