I am probably too tired but I don't understand what can be the problem: $page is a Wx::StyledTextCtrl object
this line works: $page->MarkerAdd($line_number-1, 0); though I don't see any visible change on the margin. This line $page->MarkerDefine(0, wxSTC_MARK_ARROW, "#000000", "#FFFFFF"); give me "the invocant must be a reference at lib/Padre/Frame.pm line 659." exception. Wx version 0.84 wxWidgets 2.8.7 Perl 5.8.8 Ubuntu 8.04 So what's the problem? Gabor
