Method setSelectionRect

qcustomplot/qcustomplot.cpp:13275–13290

! Sets the \ref QCPSelectionRect instance that QCustomPlot will use if \a mode is not \ref QCP::srmNone and the user performs a click-and-drag interaction. QCustomPlot takes ownership of the passed \a selectionRect. It can be accessed later via \ref selectionRect. This method is useful if you wish to replace the default QCPSelectionRect instance with an instance of a QCPSelectionRect
