We've developed an application using wxPython 2.6.1.0 for text
postprocessing. The application is running on Windows 2000 and uses a
wxStyledTextCtrl (Scintilla) for text editing. For simple colorization I
use 'SetLexer(wxSTC_LEX_CONTAINER )' and a STYLENEEDED event handler.
This works very nicely, with one exception:
If the window containing the Scintilla control is partly off the screen,
the content doesn't get repainted properly: E.g. when moving some other
window across the Scintilla control, the content of that other window
appears in the text area of the Scintilla control. If I move the Scintilla
control back into the middle of the screen, until it's fully visible, the
repainting works fine.
This behaviour is definitely connected to the STYLENEEDED handler. If I
remove it, everything is OK.
I tried to add a Refresh command to the end of the STYLENEEDED handler. It
works, but slows down scrolling a lot.
One more observation: The line numbers in the left margin are repainted
correctly.
I'd appreciate your help very much.

This is my code:
class BaseDocument(wxStyledTextCtrl):
def __init__(self,parent, main, ID):
wxStyledTextCtrl.__init__(self,parent,ID)
.
.
.
self.SetMarginLeft(0)
width = self.TextWidth(wxSTC_STYLE_LINENUMBER,"9999999")
self.SetMarginWidth(0,width)
self.SetSelBackground(1, "cyan")
self.SetLexer(wxSTC_LEX_CONTAINER )
EVT_STC_CHANGE(self,ID,self.OnChange)
EVT_STC_STYLENEEDED(self,ID, self.OnStyle)
def OnStyle(self,event):
oldend =
self.PositionFromLine(self.LineFromPosition(self.GetEndStyled()))
pos = event.GetPosition()
text = self.GetTextRange(oldend, pos)
self.StartStyling(oldend, 0xff)
self.SetStyling(pos-oldend, 2)
start = 0
while 1:
mo = RXHIG.search(text,start)
if mo:
self.StartStyling(oldend + mo.start(), 0xff)
self.SetStyling(mo.end() - mo.start(), 1)
start = mo.end()
else:
break
