createEditor() [1/2]

QWidget * QVariantDelegate::createEditor	(	QWidget *	parent,
		const QStyleOptionViewItem &	option,
		const QModelIndex &	index ) const

Creates an editor widget as child of a given widget for a specific QModelIndex

Parameters

parent	the parent widget for the editor
option	some style options that the editor should use
index	the index of the item the editor will be created for

Returns

QWidget the editor widget

createEditor() [2/2]

QWidget * QVariantDelegate::createEditor	(	QWidget *	parent,
		const QStyleOptionViewItem &	option,
		const QModelIndex &	index ) const

Parameters

editor	the editor widget that contains the new value
model	the model that contains the index
index	the index within the model whose data value should be set to the data value of the editor

setModelData() [2/2]

virtual void QVariantDelegate::setModelData ( QWidget * editor, QAbstractItemModel * model, const QModelIndex & index ) const

virtual

Sets the data of a specific QModelIndex to the value of the editor widget
