Phil,

Here is the relevant code:

//This will yield a tab that is as wide as 2 characters.

MyQsciScintilla::MyQsciScintilla()
{
   QsciScintilla();
   this->setMarginLineNumbers(1,true);
   QFont monospaced("Monospace",10);
   this->setFont(monospaced);
   this->setTabWidth(4);
}

//This will yield a tab that is as wide as 1 character.

MyQsciScintilla::MyQsciScintilla()
{
   QsciScintilla();
   this->setMarginLineNumbers(1,true);
   QFont monospaced("Monospace",10);
   this->setFont(monospaced);
   this->setTabWidth(2);
}

Thanks for the help.

Nick
