Hello,
I finally decide to try understand your code about LexerPygment so as to
define a custom lexer via Qsci.QsciLexerCustom. Here is the code I've made.
The problem with that lexer is that it doesn't colorize in red the line
which begins by #. Do you see why ?
=====================================================
class myLexer(Qsci.QsciLexerCustom):
def description(self, style):
if style == 0:
return 'ID_DEFAULT'
if style == 1:
return 'ID_COMMENT'
return ''
def defaultColor(self, style):
if style==ID_DEFAULT:
return QtGui.QColor(0,0,255)
if style==ID_COMMENT:
return QtGui.QColor(255,0,0)
return QtGui.QColor(0,0,0)
def styleText(self, start, end):
# Taken from the source code of Eric.
self.editor.startStyling(start)
if self.editor.text()[0] == '#':
self.editor.setStyling(end, ID_COMMENT)
self.editor.startStyling(start+end)
else:
self.editor.setStyling(end+1, ID_DEFAULT)
=====================================================
Can you help to find the mistakes I've made ?
Best regards.
Christophe.
