## Member Function Documentation

### `[static]` bool QFontDatabase::supportsThreadedFontRendering()

This function is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code.

Returns `true` if font rendering is supported outside the GUI thread, false otherwise. In other words, a return value of false means that all QPainter::drawText() calls outside the GUI thread will not produce readable output.

As of 5.0, always returns `true`.

This function was introduced in Qt 4.4.
