Help: Forums, postings and threads

Forums, postings and threads

Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.

Layout of the posting thread(s)

The posting threads can be shown with/without the text of the postings ("Inline depth"). In addition the depth of the thread can be controlled ("Outline depth"). For both cases several values are provided, which can be toggled. Note that the displayed values are those, which can be chosen, they do not correspond to the actual display status of the thread(s).

Show subscribers

Click "Show subscribers" to get the List of all subscribers, who receive e-mail from postings to this Forum, if they have not explictly unsubscribed from a posting thread. This includes:

Subscribers to the forum
Explicit subscribers to the posting or any of its ancestors
The author of the posting (if he has not unsubscribed)
The authors of any ancestor posting (if they have not unsubscribed)

Some browsers display old pages from the cache

Some browsers (e.g. Firefox) display a page from the cache even though the page has been updated. As a result, one may not get the latest messages in the forum's outline or the logon ID of the previous session appears on the upper right corner. If one suspects that he or she does not get the latest content of a page, try clearing up the personal data from the browser's cache as the following:

Tools -> Clear Private Data -> Clear Private Data (from browser Firefox)

Tools -> Delete Private Data (from browser Opera)

then reflesh the current page to get the latest content.

Details on "Inline depth" and "Outline depth"

Threads and the follow-up messages are numbered. There is one line per posting, normally starting with the posting number. The URLs of a posting and its responses reflect the depth of the follow-up postings. Watch the URLs to see how this is done. Depending on the chosen display options, the thread-display may be incomplete; the number of messages at the next level is, however, displayed, e.g. "…3 message(s)". You may not see all contributors unless you choose "All".

Messages are "chained" if there are only replies at the first level, i.e. 1/1.html, 1/1/1.html etc. In case of "chained" messages the message number is replaced by the icon and there is no indentation.

Inline: Display the subject line only or also the text of the posting(s); for the choice "All" the "Outline" choices are switched off.

When building my program on Windows, I get this error: libG4OpenInventor.a(G4OpenInventorWin.o) : error LNK2019: unresolved external symbol "public: static class G4Win32 * __cdecl G4Win32::getInstance(void)" (?getInstance@G4Win32@@SAPAV1@XZ) referenced in function "private: virtual void __thiscall G4OpenInventorWin::Initialize(void)" (?Initialize@G4OpenInventorWin@@EAEXXZ)

This is Geant4.9.2.p01 on Windows Xp with Cygwin and VC++ express edition 9.0. The same program worked fine with the previous Geant4.9.1.p02. It also works fine on Mac OS X and Linux, using the current Geant4.9.2.p01. I do not know what changed. I do not use the Win32 user interface (though I build it in Geant4, in case I decide to use it).

Note that I am using Coin, and must edit G4OpeninventorWin.cc to comment out lines 54-55 (omit calls to RemoveDispatcher(...) and AddDispatcher(...)). The offending call above is one line earlier.

I have a workaround: copy G4Win32.cc into my program's src directory. This forces it into the link, and all is well -- Open Inventor comes up and works fine. So this looks like a library ordering issue. Again, I do not know what changed.

NOTE: there are also a number of error messages like "the macro max requires 2 arguments but only 1 given". I never noticed them before. This happens whenever G4Win32.hh is #included and then DBL_MAX is used (the culprit is that it includes windows.h which does #define max(A,B)...). I hope the result is OK (seems to work)....
