What does these colors mean? lazarus / 9-Editor ---------------------------------------------------------------------- majid.ebru · 2018-01-24 09:22 Hi What does these colors mean? thankyou ---------------------------------------------------------------------- Handoko · 2018-01-24 09:35 Hints tell that you may be able to improve the code although sometimes nothing you can do for it. For example the Parameter sender not used. Warning is something that can cause bug in your code. Sometimes the code just run correctly. No matter it can cause problem or not, warning can be fixed. Those are what I know. I usually make my code warning-free but it still has hints. ---------------------------------------------------------------------- majid.ebru · 2018-01-24 09:53 thank you does any list or linke about these hints? ---------------------------------------------------------------------- howardpc · 2018-01-24 09:59 from the wiki: Message Marks For each compiler message listed in the Messages window the Source Editor shows  an icon in the left gutter, a line in the right gutter and the offending token is given a wavey underline. Right-clicking on the left gutter icon shows a context menu with a list of quick fixes. The wavey underlines and other marks are only updated after compilation. This differs from the real-time syntax check in new Delphi versions where the wavey underline comes and goes while typing.
