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.
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.
|1||0||1||no text / full text of posting|
|2||1||All||text for level 1 only / text for All postings|
Outline: Choose the depth of the posting thread, successive toggle controls provide increasing detail.

I've written a source where I generate a random gamma from a discrete spectrum, and feed the four-vector to G4ParticleGun for each event. The gamma energy and direction changes on each event, so this seemed like the easiest method:
G4LorentzVector myGamma = chooseGamma(); particleGun->SetParticleEnergy(myGamma.e()); particleGun->SetParticleMomentum(myGamma.vect());
Unfortunately, on every single event I get three lines of output:
[...] G4ParticleGun::gamma was defined in terms of KineticEnergy: 5.9541e-05GeV is now defined in terms Momentum: 5.9541e-05GeV/c G4ParticleGun::gamma was defined in terms of KineticEnergy: 5.9541e-05GeV is now defined in terms Momentum: 1.7061e-05GeV/c G4ParticleGun::gamma was defined in terms of KineticEnergy: 1.7061e-05GeV is now defined in terms Momentum: 5.9541e-05GeV/c [...]
It doesn't matter whether I set momentum or energy; I get the equivalent messages every time. I've looked at the source, and these messages are not protected. It wasn't obvious to me whether there was any calling sequence I could use which would let me change the gun on every event without the verbosity.
Does anyone out there have a suggestion for how I can configure G4ParticleGun on each event more silently?
