TEve Segmentation fault at end of program + other questions

ROOT
1

Dear ROOT developers,

I am using TEve (which I find really pleasant to work with), but I face one problem: At the end of my program, independently from if I had drawn geometry or markers or anything else before or not I get a seg fault.

I tried to compile the smallest possible example (which you find attached).

When running it, it runs fine until the program stops, then I get a seg-fault.
Output of the program:

./run 

create TApplication
create TEveManager
libGL warning: 3D driver claims to not support visual 0x5b
redraw
pause
Press return to continue ...

last before end
Error in <RootX11ErrorHandler>: BadWindow (invalid Window parameter) (TGedEditor XID: 17826085, XREQ: 10)
TGedEditor:     17826085
        TGCompositeFrame:       17826051
        TEveGListTreeEditorFrame:       17826050

 *** Break *** segmentation violation

I’m probably missing some line of code somewhere. I would very appreciate any help on this issue.

Besides I have another question:

  • I am drawing BoxSets and I’ve seen the possiblity to create histograms right from TEve with buttons in the “Info” section of the digitSets. These histograms have entries as set with hits->DigitValue(int), the range is from 0 to 1e6 while my entries reach at maximum 15. How can I change the range.
  • Can I add other histograms (with their respective buttons) which I can fill with other values?

thanks,
Peter

Hi Peter,

To properly exit a root application it is best to call TApplication::Terminate(). See example from ALICE event display:
alisoft.cern.ch/viewvc/trunk/EVE … ot=AliRoot
You can omit TEveManager::Terminate() to get a faster shutdown.

TEveBoxSet inherits from TEveDigitSet which holds a pointer to TEveRGBAPalette – this class holds limits and provides signal-color mapping. So, you can manually create the palette and assign it to the box-set – see tutorials tutorials/eve/boxset.C and quadset.C.

To add more histograms, have a look at tutorials/eve/histobrowser.C

If you want to add extra buttons to object-GUI, the only way is to sub-class from TEveBoxSet and also implement the GED editor class for you new class, e.g. if you create:
class TEveMyBoxSet : public TEveBoxSet …
you should also implement
class TEveMyBoxSetEditor …
and put your widgets there. Have a look at various classes ending with Editor under gui/ged/ and graf3d/eve/.

It would help if you have some experience with ROOT GUI before trying that … but it is really not too complicated if all you need is a couple of buttons.

Thinking about this … it would actually make sense to be able to attach some GUI components to EVE objects.

Cheers,
Matevz
