wxSTC toggle indic mask

As I saw in the wxPython demo, i used this code to temporary underline some text (for run-time error display):

    ed.StartStyling(836, wxSTC_INDICS_MASK)
    ed.SetStyling(10, wxSTC_INDIC0_MASK)

but now... how to toggle the underlines?

   You may need to turn off layout caching:
ed.SetLayoutCache(0)

   To see this work, in the wxPython/demo/wxStyledTextCtrl_2.py, modify the
PythonSTC class so that __init__ contains after the superclass __init__:

        self.underlineShown = 0
        self.SetLayoutCache(0)

and then in OnMarginClick:

        self.underlineShown = not self.underlineShown
        endStyled = self.GetEndStyled()
        self.StartStyling(19, wxSTC_INDICS_MASK)
        if self.underlineShown:
                self.SetStyling(19, wxSTC_INDIC0_MASK)
        else:
                self.SetStyling(19, 0)
        self.StartStyling(endStyled, 0xff)

run the demo and click in the fold margin to turn the underlining on and
off.

Sorry, to post again in this thread.. but it has a certain importance for me..

if i set up the code you sent me in the margin click event it works fine also for my application (i can't understand now..)
but the problem is that i don't want to put it in this event, but i would like that when a user click any key on keyboard the
underline text goes away.. so i put the same code inside my onModify handler, but there does not work!...

   This is correct and documented: no changes can be made in the handler for
the modified notification. You should either use the key notification or
perform the styling as a delayed task after the modification.
