Dynamic size of bar when line numbering is on is great feature, because we can easily support more than 9999 lines without unnecessarily wasting space. Of course our interface will be more scalable. Less lines = less bar size!

I have discovered that "EditorBar::SyncWidth()" should be implemented in following way:

void EditorBar::SyncWidth()
{
    int digits = 0;
    if (editor)
        digits = IntStr(editor->GetLineCount()).GetLength(); // <- Needs synchronization!!! (See description below)

    Width((line_numbers && editor ? editor->GetFont()['0'] * digits + 12 + 4 : 12 + 4) + annotations); // <- 4 is additional margin for annotation.
    Refresh();
}

The problem here is that SyncWidth should be invoking in different place in CodeEditor class for example putting new line or removing it or on file load. This is hard because I don't know where the file is loaded to code editor. Should we ovverride "SetData" method?

- In this task linenumbering should handle 999 999 lines or even more. It is usefull for huge files.
