[wx-dev] wxRichTextCtrl newline linking bug

[Tom Gersic]

Ah, I found _a_ way to fix it, but i don't know if it's a particularly 
good way to do it...In the OnMoveMouse function in richtextctrl.cpp 
(line 436), there's a bit of code that checks to see if "we need to 
change the cursor". If the mouse is positioned after the last character 
in a line, the position being returned here is the position of the last 
character in the line. I imagine the proper way to fix this would be to 
make sure that it doesn't return the last character in the line unless 
the mouse is actually over that character, but I'm not sure how to do 
that. One way to fix it, though, is to check whether the character after 
the position being returned is a newline. If it is, don't change the 
cursor. That solves the onMouseMove, but onLeftUp, etc. need similar 
adjustments.

        if (hit != wxRICHTEXT_HITTEST_NONE)
        {
            wxTextAttrEx attr;

            if (GetStyle(position, attr))
            {
                if (attr.HasFlag(wxTEXT_ATTR_URL))
                {
                    wxString daContent = GetValue().Mid(position+1,1);
                    if(daContent.CmpNoCase("\n") != 0)
                    {
                        SetCursor(m_urlCursor);
                    }
                    else
                    {
                        SetCursor(m_textCursor);
                    }
                }
                else if (!attr.HasFlag(wxTEXT_ATTR_URL))
                {
                    SetCursor(m_textCursor);
                }
            }
