详细描述
The QTableWidgetSelectionRange class provides a way to interact with selection in a model without using model indexes and a selection model.
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.
参见 QTableWidget.
成员函数
QTableWidgetSelectionRange::QTableWidgetSelectionRange()
Constructs an table selection range, i.e. a range whose rowCount() and columnCount() are 0.
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.
参见 topRow(), leftColumn(), bottomRow(), and rightColumn().
QTableWidgetSelectionRange::QTableWidgetSelectionRange(const QTableWidgetSelectionRange &other)
Constructs a the table selection range by copying the given other table selection range.
QTableWidgetSelectionRange::~QTableWidgetSelectionRange()
Destroys the table selection range.
int QTableWidgetSelectionRange::bottomRow() const
Returns the bottom row of the range.
参见 topRow(), rightColumn(), and rowCount().
int QTableWidgetSelectionRange::columnCount() const
Returns the number of columns in the range.
This is equivalent to rightColumn() - leftColumn() + 1.
This function was introduced in Qt 4.1.
参见 rowCount(), leftColumn(), and rightColumn().
int QTableWidgetSelectionRange::leftColumn() const
Returns the left column of the range.
参见 rightColumn(), topRow(), and columnCount().
int QTableWidgetSelectionRange::rightColumn() const
Returns the right column of the range.
参见 leftColumn(), bottomRow(), and columnCount().
int QTableWidgetSelectionRange::rowCount() const
Returns the number of rows in the range.
This is equivalent to bottomRow() - topRow() + 1.
This function was introduced in Qt 4.1.
参见 columnCount(), topRow(), and bottomRow().
int QTableWidgetSelectionRange::topRow() const
Returns the top row of the range.
参见 bottomRow(), leftColumn(), and rowCount().
