I don't think you convinced "the company Nokia" - most of the company will not even read your bugreport or this mailing list.

As with almost all programing concepts it's all about having guidelines for the concept's uses, so they don't get out of control. That applies to the examples above too, both friend declarations and nested classes. BTW, nested classes (and structs and enums in classes) are used at several places throughout Qt and Qt Creator, exactly for namespacing + encapsulation. -- Eike Ziller Software Engineer Nokia, Qt Development Frameworks Nokia gate5 GmbH Firmensitz: Invalidenstr. 117, 10115 Berlin, Germany Registergericht: Amtsgericht Charlottenburg, Berlin: HRB 106443 B Umsatzsteueridentifikationsnummer: DE 812 845 193 Geschäftsführer: Dr. Michael Halbherr, Karim Tähtivuori ___ Qt-creator mailing list Qt-creator@trolltech.com http://lists.trolltech.com/mailman/listinfo/qt-creator

I reported the crash-bug both on this list (several times) and here http://bugreports.qt.nokia.com/browse/QTCREATORBUG-199 but it was reported 'un-reproducable'.

You should write code based on best coding and design practice, not to
adhere to the whims of a particular IDE's syntax completion. Class nesting
is like function nesting in old C - it get's out of control fast. Pmpl is an
exception (and in that case the class is defined within the cpp file
anyway). For most other cases, class friendships are better.

Some people actually like to use trivial nested classes to aid in code
completion. It can be convenient to type in something like "aaa." and
then quickly choose what you want. Think of it as a namespace within a
class.
Two new discoveries:
1) Code completion is not the only problem. "Find usages" doesn't work
either.
2) If you separate the member declaration from the nested class
declaration, neither problem occurs. This a good workaround. See example
below:
class MainWindow : public QMainWindow {
Q_OBJECT
public:
explicit MainWindow(QWidget *parent = 0);
~MainWindow();
private:
Ui::MainWindow *ui;
class AAA
{
public:
int a;
int b;
int c;
} aaa; //code completion and "find usages" don't work
AAA bbb; //code completion and "find usages" work
};

Re: [Qt-creator] code completion anomaly
Creator seems to have issues with nested classes. It actually used to crash
in this case but that bug was fixed (once I finally convinced Nokia it was a
problem...).
My adivce is to not use nested classes.

[Qt-creator] code completion anomaly
Hi,
This is a question about code completion in Qt Creator. I have been
enjoying using Qt Creator built from the latest git sources.
Here is the issue:
Code completion in the does not seem to work right for member class
declarations. For the example below:
"aaa->" triggers code completion but should not.
"aaa." should trigger code completion but does not.
Is this really wrong, or is there more to this than meets the eye.
regards,
Mark
