Detailed Description

StandardItemModel derives from QStandardItemModel and therefore shares all of its functionality, but this Qx variant provides additional functionality and mechanisms that are missing from its base class.

Note: One significant functional difference from the base class version to be aware of is that the Qt::ItemIsAutoTristate flag of any item managed by this model will always be respected, regardless of which view it is attached to. In base Qt the auto tristate flag only functions for items behind a QTreeWidget.

Constructor & Destructor Documentation

◆ StandardItemModel() [1/2]

Qx::StandardItemModel::StandardItemModel	(	int	rows,
		int	columns,
		QObject *	parent = nullptr )

Constructs a new item model that initially has rows rows and columns columns, and that has the given parent.

◆ StandardItemModel() [2/2]

Qx::StandardItemModel::StandardItemModel ( QObject * parent = nullptr )

Constructs a new item model with the given parent.

Member Function Documentation

◆ forEachItem()

void Qx::StandardItemModel::forEachItem	(	std::function< void(QStandardItem *)> const &	func,
		QModelIndex	parent = QModelIndex() )

Calls a user-defined routine on multiple items within the model.

Parameters

func	The function to call on each item. It must take a single argument of type QStandardItem* and return `void`.
parent	A model index pointing to the item for processing to start at. A null index causes processing to start at the root item of the model, thereby calling the routine on all items.

◆ isAutoTristate()

bool Qx::StandardItemModel::isAutoTristate ( )

Returns true if the item model is set to auto tristate mode; otherwise returns false.

See also: setAutoTristate().

◆ selectAll()

void Qx::StandardItemModel::selectAll ( )

Sets the check state of all checkable items that are managed by the model to Qt::Checked.

See also: setAutoTristate().

◆ selectNone()

void Qx::StandardItemModel::selectNone ( )

Sets the check state of all checkable items that are managed by the model to Qt::Unchecked.

See also: setAutoTristate().

◆ setAutoTristate()

void Qx::StandardItemModel::setAutoTristate ( bool autoTristate )

Enables treatment of all checkable child items as tristate if autoTristate is true

This enables model-wide automatic management of the state of parent items in the model (checked if all children are checked, unchecked if all children are unchecked, or partially checked if only some children are checked).

Note: Even if this option is false, items handled by the model that have the flag Qt::ItemIsAutoTristate will still be treated as such.

◆ setData()

bool Qx::StandardItemModel::setData	(	const QModelIndex &	index,
		const QVariant &	value,
		int	role = Qt::EditRole )

virtual

Reimplements: QStandardItemModel::setData(const QModelIndex& index, const QVariant& value, int role).

Reimplemented from QStandardItemModel.
