QToolButton + style sheet problem

[Lykurg]

I tried this. I wrote the above line in a .qss file and read it. But it didnt work, that is why I am am looking for a direct implementation.

Did you mean by "direct implementation" setting the qss on the toolbutton? If so, that makes no difference and also there you have to respect the css syntax:

tb->setStyleSheet ("::down-arrow {subcontrol-position: right center}");

tb->setStyleSheet ("::down-arrow {subcontrol-position: right center}");

To copy to clipboard, switch view to plain text mode

Si necesitas estilizar y/o quieres controlar la flecha hacia abajo de los botones QToolButton de un QToolBar, es posible que tengas problemas cuando los creas a partir de QAction. La manera de acceder a ello es utilizando QToolButton::menu-arrow {...} o QToolButton::menu-button {...}

Si tu tienes una barra de navegación la puedes nombrar barra->setObjectName("miBarra");
Y puedes controlar su flecha abajo con #miBarra QToolButton::menu-arrow {...} o #miBarra QToolButton::menu-button {...}
