src/log4qt/rollingfileappender.h:79: Warning: Property declaration maxFileSize has no READ accessor function. The property will be invalid.
Per the QT docs (http://doc.trolltech.com/4.5/properties.html):
"A READ accessor function is required. It is for reading the property value. It must be const and must return either the property's type or a pointer or reference to that type. e.g., QWidget::focus is a read-only property with READ function QWidget::hasFocus()."
I wasn't clear on where that accessor was being used, but if it is used, my suggestion would be switch to using the function directly if possible. Or save the string on a "set" and return that for a "get" (or return null if "set" with a string was never called).
The accessor is needed by the PropertyConfigurator to set the property on the RollingFileAppender. I will add a corresponding get method.
