## Detailed Description

The QTableWidgetSelectionRange class stores the top left and bottom right rows and columns of a selection range in a table. The selections in the table may consist of several selection ranges.

Note: If the item within the selection range is marked as not selectable, e.g., `itemFlags() & Qt::ItemIsSelectable == 0` then it will not appear in the selection range.

See also QTableWidget.

## Member Function Documentation

### `[constexpr noexcept]` QTableWidgetSelectionRange::QTableWidgetSelectionRange()

Constructs an empty table selection range, i.e. a range whose rowCount() and columnCount() are 0.

See also topRow(), leftColumn(), bottomRow(), and rightColumn().

### QTableWidgetSelectionRange::QTableWidgetSelectionRange(int top, int left, int bottom, int right)

Constructs the table selection range from the given top, left, bottom and right table rows and columns.

See also topRow(), leftColumn(), bottomRow(), and rightColumn().

### int QTableWidgetSelectionRange::bottomRow() const

Returns the bottom row of the range.

See also topRow(), rightColumn(), and rowCount().

### int QTableWidgetSelectionRange::columnCount() const

Returns the number of columns in the range.

This is equivalent to rightColumn() - leftColumn() + 1.

See also rowCount(), leftColumn(), and rightColumn().

### int QTableWidgetSelectionRange::leftColumn() const

Returns the left column of the range.

See also rightColumn(), topRow(), and columnCount().

### int QTableWidgetSelectionRange::rightColumn() const

Returns the right column of the range.

See also leftColumn(), bottomRow(), and columnCount().

### int QTableWidgetSelectionRange::rowCount() const

Returns the number of rows in the range.

This is equivalent to bottomRow() - topRow() + 1.

See also columnCount(), topRow(), and bottomRow().

### int QTableWidgetSelectionRange::topRow() const

Returns the top row of the range.

See also bottomRow(), leftColumn(), and rowCount().

### `[noexcept, since 6.3]` bool operator!=(const QTableWidgetSelectionRange &lhs, const QTableWidgetSelectionRange &rhs)

Returns true if lhs and rhs are not equal, otherwise returns false.

This function was introduced in Qt 6.3.

### `[noexcept, since 6.3]` bool operator==(const QTableWidgetSelectionRange &lhs, const QTableWidgetSelectionRange &rhs)

Returns true if lhs and rhs are equal, otherwise returns false.
