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)|
Hi, I would suggest you to check whether you have unnecessary "hard-coded" UI commands. For example, which is one of the most typical user's mistake, don't you use UI command instead of directly invoking the proper set-method for changing the direction of primary particles generated by G4ParticleGun? In current implementation, G4UImanager keeps all UI commands as history. Thus if your code has G4UImanager::ApplyCommand() method within event loop, the size of your program is getting begger as the number of processed event. This is not a memory leak. All stored history will be deleted at the end of program. In the next public release, G4UImanager will have a limit for the number of stored history. Thus you will not see any memory exhaust by UI commands. On the other hand, UI command should not be used for this kind of "frequent" and "massively used" setting. It is mush slower compared to direct method invokation.
