The QTextItem class provides all the information required to draw text in a custom paint engine.
When you reimplement your own paint engine, you must reimplement QPaintEngine::drawTextItem(), a function that takes a QTextItem as one of its arguments.

|---|---|---|
| QTextItem::RightToLeft | 0x1 | Render the text from right to left. |
| QTextItem::Overline | 0x10 | Paint a line above the text. |
| QTextItem::Underline | 0x20 | Paint a line under the text. |
| QTextItem::StrikeOut | 0x40 | Paint a line through the text. |
