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.
|1||2||1||2 levels / 1 level (original posting)|
|2||3||2||3 levels / 2 levels|
|3||3||All||3 levels / all levels (all postings)|
For any step you have PreStepPoint and PostStepPoint. For any G4StepPoint you can get a pointer to a process defined the step:
G4VProcess* proc = G4StepPoint::GetProcessDefinedStep();
from that one can have:
G4int subtype = proc->GetProcessSubType(); G4ParticleDefinition* type = proc->GetProcessManager()->GetParticleType();
I would suggest to use first method as the most simple if you can. Subtypes per process are well defined and are available in Geant4 web or via LXR code browse.
We usually do not recommend to use string names to identify particles and processes in run time at each step, because it is not CPU effective.
