References explodeFactor(), and gapFactor().

        gapFactor( false) == r.gapFactor( false);
}

void PieAttributes::setExplode

(

bool

explode

)

Enable or disable exploding the respective pie piece(s).

The default explode factor is 10 percent; use setExplodeFactor to specify a different factor.

Note:

This is a convenience function: Calling setExplode( true ) does the same as calling setExplodeFactor( 0.1 ), and calling setExplode( false ) does the same as calling setExplodeFactor( 0.0 ).

References d.

{
    d->explodeFactor = (enabled ? 0.1 : 0.0);
}

void PieAttributes::setExplodeFactor

(

qreal

factor

)

Set the explode factor.

The explode factor is a qreal between 0 and 1, and is interpreted as a percentage of the total available radius of the pie.
