Qlabel settext not updating

A QLabel is often used as a label for an interactive widget. Note: The text Interaction Flags set on the label need to include either Text Selectable By Mouse or Text Selectable By Keyboard.

By default, labels display left-aligned, vertically-centered text and images, where any tabs in the text to be displayed are automatically expanded.

When the content is changed using any of these functions, any previous content is cleared.

By default, labels display left-aligned, vertically-centered text and images, where any tabs in the text to be displayed are automatically expanded. When the user presses the shortcut key indicated by this label, the keyboard focus is transferred to the label's buddy widget. This method is also a Qt slot with the C signature .

For example: In this example, keyboard focus is transferred to the label's buddy (the QLine Edit) when the user presses Alt P.

If the buddy was a button (inheriting from QAbstract Button), triggering the mnemonic would emulate a button click.
