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 on
windows only and I have no idea if it works correctly on other
platforms.

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.


1. USAGE
~~~~~~~~

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-widet:

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. NOTE
~~~~~~~

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
...


$ cd ../wxtextview
$ python wxtextview.py
####################### wxtextview.py #######################
> test_00: ................................................. ok
> test_01: ................................................. ok
> test_02: ................................................. ok
...

$ python wxtextview.py demo_00
