## Detailed Description

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.

## Member Type Documentation

### enum QTextItem::RenderFlag
flags QTextItem::RenderFlags

Constant | Value | Description
--- | --- | ---
`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.

The RenderFlags type is a typedef for QFlags<RenderFlag>. It stores an OR combination of RenderFlag values.
