Questions tagged [qlabel]

The QLabel widget, part of the Qt framework, provides a text or image display.

No user interaction functionality is provided. The visual appearance of the label can be configured in various ways, and it can be used for specifying a focus mnemonic key for another widget.

The official Qt documentation can be found here for Qt 4.8 and here for Qt 5.
