Text un-ordering on QPushButton if " x " surrounded by numbers.

I am trying to set the text of a QPushButton to show dimensions. Whenever it is in the format "123 x 321" the ordering of the text gets changed around to "x 321 123". However if I remove the spaces around the x, and have the format "123x321", it displays correctly.

The code I am using...

QString text = QString::number(width) + " x " + QString::number(height);
ui_>customDimensionButton_>setText(text);
