[Interest] Re using graphics effects

[Graham Labdon]

Hi
I have applied a graphics effect to a widget -
        QGraphicsOpacityEffect* opacityEffect = new QGraphicsOpacityEffect(this); // make sure to create using new, since effect has to be alive as long as the target widget is using it.
        opacityEffect->setOpacity(0.0); // initially widget should be invisible
        ui.buttonLabel_4->setGraphicsEffect(opacityEffect);

Now I want the same effect on another widget so I did this -
        ui.buttonLabel_5->setGraphicsEffect(opacityEffect);

This has the effect of making the second widget transparent but makes the first visible.
Why am I unable to share the graphics effect object?

Thanks
