I'm trying to convert text to HTML.

Here is the code.

m_pTextCtrl is a wxTextCtrl.

--- Code: ---wxString MainFrame::TextToHTML()
{
const wxString sOO = _T("00");
const wxString s8O = _T("80");
const wxString sFF = _T("FF");

wxString htmlString;

htmlString << _T("<html><head><title></title></head><body><tt>");

long max = m_pTextCtrl->GetLastPosition();

wxTextAttr style;

wxTextAttr oldStyle;

wxChar ch;

for(long pos = 0; pos < max; pos++)
{
m_pTextCtrl->GetStyle(pos, style);

if(style != oldStyle)
{
if(pos > 0)
{
htmlString << _T("</font>");
}

wxString sR, sG, sB;

wxColour colour = style.GetTextColour();

sR.Printf(_T("%02X"), colour.Red());
sG.Printf(_T("%02X"), colour.Green());
sB.Printf(_T("%02X"), colour.Blue());

htmlString << _T("<font color = \"#") << sR << sG << sB << _T("\">"); ;
}

if (m_pTextCtrl->GetInsertionPoint() == m_pTextCtrl->GetLastPosition())
{
ch = _T('\0');
}

else
{
ch = m_pTextCtrl->GetValue[m_pTextCtrl->GetInsertionPoint()];
}

switch(ch)
{
case _T('\n'):
{
htmlString << _T("\n<br>");
}
break;

case _T('<'):
{
htmlString << _T("<");
}
break;

case _T('&'):
{
htmlString << _T("&");
}
break;

case _T(' '):
{
htmlString << _T(" ");
}
break;

default:
{
htmlString << ch;
}
break;
}

oldStyle = style;
}

htmlString << _T("</font></tt></body></html>");

return htmlString;
}

--- End code ---

I get build errors though...

What am I doing wrong?

Ceniza:
It seems like there's no operator != overloaded for wxTextAttr, so if(style != oldStyle) cannot be compiled.

sethjackson:
but what about this.

--- Code: ---error: invalid types `<unknown type>[long int]' for array subscript

--- End code ---

Change ch = m_pTextCtrl->GetValue[m_pTextCtrl->GetInsertionPoint()];
to ch = m_pTextCtrl->GetValue()[m_pTextCtrl->GetInsertionPoint()];

(notice the parentheses)

sethjackson:
I tried that. I still get errors

--- Code: ---main.cpp:235: error: ambiguous overload for 'operator[]' in '*(((MainFrame*)this)->MainFrame::m_pTextCtrl->wxTextCtrl::_vptr$wxObject + 768u)()[(*(((MainFrame*)this)->MainFrame::m_pTextCtrl->wxTextCtrl::_vptr$wxObject + 936u))(((MainFrame*)this)->MainFrame::m_pTextCtrl)]'

--- End code ---

I got

--- Code: ---m_pTextCtrl->GetValue[m_pTextCtrl->GetInsertionPoint()];

--- End code ---

From the wxWidgets manual so it should work I thought....
