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.

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.
