I am using the following Highlighter class for Spell Checking to work on my
QTextEdit.
class Highlighter(QSyntaxHighlighter):
In Python 2.7, the re module has a somewhat limited idea of what a
"word" character is. It recognises 'DEVANAGARI LETTER NA' as a letter,
but 'DEVANAGARI VOWEL SIGN E' as a diacritic. The pattern ur'(?u)\w+'
will therefore split "नेपाली" into 3 parts.
pattern = ur'\w+'
def __init__(self, *args):
QSyntaxHighlighter.__init__(self, *args)
self.dict = None
def setDict(self, dict):
self.dict = dict
def highlightBlock(self, text):
if not self.dict:
return
text = unicode(text)
format = QTextCharFormat()
format.setUnderlineColor(Qt.red)
format.setUnderlineStyle(QTextCharFormat.SpellCheckUnderline)
The LOCALE flag is for locale-sensitive 1-byte per character
bytestrings. It's rarely useful.
The UNICODE flag is for dealing with Unicode strings, which is what you
need here. You shouldn't be using both at the same time!
unicode_pattern=re.compile(self.pattern,re.UNICODE|re.LOCALE)
for word_object in unicode_pattern.finditer(text):
if not self.dict.spell(word_object.group()):
print word_object.group()
self.setFormat(word_object.start(), word_object.end() -
word_object.start(), format)
But whenever I pass unicode values into my QTextEdit the re.finditer() does not
seem to collect it.
When I pass "I am a नेपाली" into the QTextEdit. The output is like this:
I I I a I am I am I am a I am a I am a I am a I am a I am a I am a I am a
It is completely ignoring the unicode. What might be the issue. I am new to
PyQt and regex. Im using Python 2.7 and PyQt4.
There's an alternative regex implementation at:
http://pypi.python.org/pypi/regex
It's a drop-in replacement for the re module, but with a lot of
additions, including better handling of Unicode.
