Struct qt_gui::QTextItem

#[repr(C)]
pub struct QTextItem { /* fields omitted */ }

The QTextItem class provides all the information required to draw text in a custom paint engine.

C++ class: QTextItem.

C++ documentation:

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.
