+    should be integers, and for QDoubleValidator they should be doubles. QRegExpValidator
+    has a single string property, regExp, which should be set to the regular expression to
+    be used for validation. An example of using validators is shown below, which allows
+    input of integers between 11 and 31 into the text input:

+    Set this property if you want the text to be smoothly scaled or

+    the item is displayed at its natural size, this property has no visual or
+    performance effect.
+
+    \note Generally scaling artifacts are only visible if the item is stationary on
+    the screen.  A common pattern when animating an item is to disable smooth
+    filtering at the beginning of the animation and reenable it at the conclusion.
