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 some of the examples using OpenGLStoreQt the detector is not displayed and the list of touchable on the left only shows the "World" volume.
(This appears to be specific to VisualC++. I don't see it on my Scientific Linux
In example B4a when I do:
Logical Volume "World": vis attributes: G4VisAttributes: visible, daughters invisible, colour: (-1.68976e+299,4.55526e-304,1.14503e-125,-1.15056e+297) linestyle: unrecognised, line width: 1.14503e-125 drawing style: forced to: unrecognized, auxiliary edge visibility: forced line segments per circle: forced to 15990152 time range: (1.14503e-125,-8.05742e+292) G4AttValue pointer is non-zero, G4AttDef pointer is non-zero Logical Volume "Calorimeter": vis attributes: G4VisAttributes: visible, daughters visible, colour: (1,1,1,1) (white) linestyle: solid, line width: 1 drawing style: not forced, auxiliary edge visibility: not forced line segments per circle: not forced. time range: (-1.79769e+308,1.79769e+308) G4AttValue pointer is zero, G4AttDef pointer is zero Logical Volume "Layer": vis attributes: G4VisAttributes: zero G4VisAttributes pointer Logical Volume "Abso": vis attributes: G4VisAttributes: zero G4VisAttributes pointer Logical Volume "Gap": vis attributes: G4VisAttributes: zero G4VisAttributes pointer
The problem was fixed by replacing line 265 of B4DetectorConstruction.cc by:
worldLV->SetVisAttributes (new G4VisAttributes(false,G4Colour::White()));
which defines a color for the world volume.
I am using Geant4.10.00, VisualC++10, and Qt4.8.4 under 64-bit Windows 7.
