Detailed Description

The QItemSelectionRange class manages information about a range of selected items in a model.

A QItemSelectionRange contains information about a range of selected items in a model. A range of items is a contiguous array of model items, extending to cover a number of adjacent rows and columns with a common parent item; this can be visualized as a two-dimensional block of cells in a table. A selection range has a top(), left() a bottom(), right() and a parent().

The QItemSelectionRange class is one of the Model/View Classes and is part of Qt's model/view framework.

The model items contained in the selection range can be obtained using the indexes() function. Use QItemSelectionModel::selectedIndexes() to get a list of all selected items for a view.

You can determine whether a given model item lies within a particular range by using the contains() function. Ranges can also be compared using the overloaded operators for equality and inequality, and the intersects() function allows you to determine whether two ranges overlap.

See also Model/View Programming, QAbstractItemModel, QItemSelection, and QItemSelectionModel.

Constructor & Destructor Documentation

QtGui.QItemSelectionRange.QItemSelectionRange ( System.Type  dummy )

protected

QtGui.QItemSelectionRange.QItemSelectionRange

(

)

Constructs an empty selection range.

QtGui.QItemSelectionRange.QItemSelectionRange

(

QItemSelectionRange

other

)

Copy constructor. Constructs a new selection range with the same contents as the other range given.

QtGui.QItemSelectionRange.QItemSelectionRange

(

QModelIndex

index

)

Constructs a new selection range containing only the model item specified by the model index index.

QtGui.QItemSelectionRange.QItemSelectionRange	(	QModelIndex	topLeft,
		QModelIndex	bottomRight
	)

Constructs a new selection range containing only the index specified by the topLeft and the index bottomRight.

Member Function Documentation

new int QtGui.QItemSelectionRange.Bottom

(

)

Returns the row index corresponding to the lowermost selected row in the selection range.

new QModelIndex QtGui.QItemSelectionRange.BottomRight

(

)

Returns the index for the item located at the bottom-right corner of the selection range.

See also bottom(), right(), and topLeft().

new bool QtGui.QItemSelectionRange.Contains

(

QModelIndex

index

)

Returns true if the model item specified by the index lies within the range of selected items; otherwise returns false.

new bool QtGui.QItemSelectionRange.Contains	(	int	row,
		int	column,
		QModelIndex	parentIndex
	)

This is an overloaded function.

Returns true if the model item specified by (row, column) and with parentIndex as the parent item lies within the range of selected items; otherwise returns false.

virtual void QtGui.QItemSelectionRange.CreateProxy ( )

virtual

new void QtGui.QItemSelectionRange.Dispose

(

)

override bool QtGui.QItemSelectionRange.Equals

(

object

o

)

override int QtGui.QItemSelectionRange.GetHashCode

(

)

new int QtGui.QItemSelectionRange.Height

(

)

Returns the number of selected rows in the selection range.

new System.Collections.Generic.List<QModelIndex> QtGui.QItemSelectionRange.Indexes

(

)

Returns the list of model index items stored in the selection.

new QItemSelectionRange QtGui.QItemSelectionRange.Intersect

(

QItemSelectionRange

other

)

Use intersected(other) instead.

new QItemSelectionRange QtGui.QItemSelectionRange.Intersected

(

QItemSelectionRange

other

)

Returns a new selection range containing only the items that are found in both the selection range and the other selection range.

This function was introduced in Qt 4.2.

new bool QtGui.QItemSelectionRange.Intersects

(

QItemSelectionRange

other

)

Returns true if this selection range intersects (overlaps with) the other range given; otherwise returns false.

new bool QtGui.QItemSelectionRange.IsEmpty

(

)

Returns true if the selection range contains no selectable item

This function was introduced in Qt 4.7.

new bool QtGui.QItemSelectionRange.IsValid

(

)

Returns true if the selection range is valid; otherwise returns false.

new int QtGui.QItemSelectionRange.Left

(

)

Returns the column index corresponding to the leftmost selected column in the selection range.

new QAbstractItemModel QtGui.QItemSelectionRange.Model

(

)

Returns the model that the items in the selection range belong to.

static bool QtGui.QItemSelectionRange.operator!= ( QItemSelectionRange  arg1, QItemSelectionRange  arg2  )

static

Returns true if the selection range differs from the other range given; otherwise returns false.

static bool QtGui.QItemSelectionRange.operator< ( QItemSelectionRange  arg1, QItemSelectionRange  arg2  )

static

bool QItemSelectionRange::operator== ( const QItemSelectionRange & other ) const

Returns true if the selection range is exactly the same as the other range given; otherwise returns false.

static bool QtGui.QItemSelectionRange.operator== ( QItemSelectionRange  arg1, QItemSelectionRange  arg2  )

static

Returns true if the selection range is exactly the same as the other range given; otherwise returns false.

static bool QtGui.QItemSelectionRange.operator> ( QItemSelectionRange  arg1, QItemSelectionRange  arg2  )

static

new QModelIndex QtGui.QItemSelectionRange.Parent

(

)

Returns the parent model item index of the items in the selection range.

new int QtGui.QItemSelectionRange.Right

(

)

Returns the column index corresponding to the rightmost selected column in the selection range.

new int QtGui.QItemSelectionRange.Top

(

)

Returns the row index corresponding to the uppermost selected row in the selection range.

new QModelIndex QtGui.QItemSelectionRange.TopLeft

(

)

Returns the index for the item located at the top-left corner of the selection range.

See also top(), left(), and bottomRight().

new int QtGui.QItemSelectionRange.Width

(

)

Returns the number of selected columns in the selection range.
