The value for wxstc.wxSTC_MASK_FOLDERS has to be -33554432 or maybe -0x2000000
or SetMarginMask should expect an unsigned int (I did not check that). both the following print(string.format('%x',-33554432)) print(string.format('%x',-0x2000000)) print(string.format('%x',wxstc.wxSTC_MASK_FOLDERS)) print(-0x2000000 == wxstc.wxSTC_MASK_FOLDERS) output: fe000000 fe000000 fe000000 false the values display identical string but are not equal.
