详细描述

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.

注意： 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.

[constexpr noexcept] QTableWidgetSelectionRange:: QTableWidgetSelectionRange ()

Constructs an empty table selection range, i.e. a range whose rowCount () 和 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.

另请参阅 topRow (), leftColumn (), bottomRow ()，和 rightColumn ().

int QTableWidgetSelectionRange:: bottomRow () const

Returns the bottom row of the range.

另请参阅 topRow (), rightColumn ()，和 rowCount ().

int QTableWidgetSelectionRange:: columnCount () const

Returns the number of columns in the range.

这相当于 rightColumn () - leftColumn () + 1.

另请参阅 rowCount (), leftColumn ()，和 rightColumn ().

int QTableWidgetSelectionRange:: leftColumn () const

Returns the left column of the range.

另请参阅 rightColumn (), topRow ()，和 columnCount ().

int QTableWidgetSelectionRange:: rightColumn () const

Returns the right column of the range.

另请参阅 leftColumn (), bottomRow ()，和 columnCount ().

int QTableWidgetSelectionRange:: rowCount () const

Returns the number of rows in the range.

这相当于 bottomRow () - topRow () + 1.

另请参阅 columnCount (), topRow ()，和 bottomRow ().

int QTableWidgetSelectionRange:: topRow () const

Returns the top row of the range.

另请参阅 bottomRow (), leftColumn ()，和 rowCount ().
