Add title : "QCPPlotTitle" cannot be recognized in my complierReturn to overview

I had managed to plot my curve and prepared to add tilte to my plot, but after I added the following two lines referring to some data from Internet :

ui.qplot->plotLayout()->insertRow(0);
ui.qplot->plotLayout()->addElement(0, 0, new QCPPlotTitle(ui.qplot, "title"));

but the complier told me "Syntax Error : Indentifer "QCPPlotTitle""
that meant "QCPPlotTitle " could not be recognized by my complier.
I use the newest version (2.0.0 beta) and I have included the "qcustomplot.h" and "qcustomplot.cpp" to my project , do I leave out someting else which needs adding to my codes ?

Or, any other idea to add title ?
I'll appreciate it if any one can help me out.

In QCP 2.0, the QCPPlotTitle was replaced by QCPTextElement. (See changenotes and documentation for details.)
