Constructor & Destructor Documentation

◆ QgsRendererCategory() [1/3]

QgsRendererCategory::QgsRendererCategory ( )

default

Constructor for QgsRendererCategory.

◆ QgsRendererCategory() [2/3]

QgsRendererCategory::QgsRendererCategory	(	const QVariant &	value,
		QgsSymbol *	symbol,
		const QString &	label,
		bool	render = `true`
	)

Constructor for a new QgsRendererCategory, with the specified value and symbol.

If value is a list, then the category will match any of the values from this list.

The ownership of symbol is transferred to the category.

The label argument specifies the label used for this category in legends and the layer tree.

The render argument indicates whether the category should initially be rendered and appear checked in the layer tree.
