I have a QML based application in Qt that generates some warnings at runtime:
QDeclarativeExpression: Expression "(function $text() { return pinyin
})" depends on non-NOTIFYable properties:
hanzi::DictionaryEntry::pinyin
I believe it refers to this class which has some properties with no notifier (because not needed):
#ifndef DICTIONARYENTRY_H
#define DICTIONARYENTRY_H
namespace hanzi {
class DictionaryEntry : public QObject {
Q_PROPERTY(QString simplified READ simplified)
Q_PROPERTY(QString traditional READ traditional)
Q_PROPERTY(QString pinyin READ pinyin)
Q_PROPERTY(QString definition READ definition)
explicit DictionaryEntry(QObject* parent = 0);
const QString& simplified()
const QString& traditional()
const QString& pinyin()
const QString& rawDefinition()
const QStringList& definitions()
const QString& definition()
void setSimplified(const QString& v);
void setTraditional(const QString& v);
void setPinyin(const QString& v);
void setDefinitions(const QStringList& v);
#endif // DICTIONARYENTRY_H
Does anybody know why it's showing these warnings, and, if they are not important, is there any way to disable them?

If the property values can change, then QML needs a NOTIFY signal so it can know when they have changed and update property bindings.
If they can't change, add CONSTANT to your property declaration, for example:
Q_PROPERTY(QString simplified READ simplified CONSTANT).
In your case, there are set methods, which implies the properties can change, but if they don't change when they're being used in your QML, you can get rid of the warnings by marking them as CONSTANT.

following on from this thread
I have a problem that only sensibly gets the same title, and is very related (I think)
And as I can't put my question into that thread I have to create a new one.
Aslo this is a very long post (how do you include reports for file so as they have scroll bars
C:\mvn --version

I performed the steps as suggested by AKB. but no change. The result of
mvn -X archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false > z:\mvnError.txt
are rather long, so'll i'll post the first failure here, and the full output after my signature.

So I then navigated to the file maven-parent-16.POM and it is a self generated HTML file. It contains info about my works server, and a load of link references in the head of the file.
Obviously this being an HTML file it doesn't meet the strick XML standard for closing tags etc. Do I need to edit these so as they meet the XML strictness. If that is the case then that is fine, but sure if maven creates these files then it should be happy with the structure! I think I may have just understood... the server is blocking the site related to this POM, this is the page I get returned when I hit a 'banned' site from work (all MS sites are blocked as a 'security' measure, yes thats right our network sys admin is a true linux daemon!)...
So that changes my problem a little bit...
I've searched for the POM file that matches the maven-clean-plugin , and the file is there, so I guess it is one of the dependencies, how can I determine which it is that is causing the initial error (I'm sure it is in output, but I don't know what I'm looking for). Then I can just hunt down the requied jar and POM and yipee. Maven should work!
Very quickly, looking at the pom file there are a bunch of 'module' that I guess this file is attempting to dowload. I only have a small selection of them in my local reposiories folder. Is it caused by the server timing out? or am I really being blocked from the site?
Thanks in advance for any help or suggestions I have been trying to solve this now for 2 days!
I can't seem to add the full output of the failure, I'll try again if anyone requires it.

From the logs it is evident that dependant maven artifacts are not getting downloaded - most likely due to &proxy& misconfiguration.
It could be due to same reason as the
post referred in the question.
The local repository manager itself would not have solved the problem without appropriate changes to settings.xml since this also would have gone through the proxy.
