TEve draw children

ROOT
1

Dear Rooters,
I have following problem. I have Event Display with V0 particles, V0 is one TEveTrack with two “daughter/elements” - TEveTracks that represent the decay products.
However I have problem with “highlighting” them - when I click on V0, negative or positive daughter only one TEveTrack is “highlighted”, Is it possible to highlight all three TEveTracks? Just like for TPointSet3D - here when i click on one point all of them are highlighted. I thought that CSCImplySelectAllChildren solves (at leas problem with highlighting daughters of V0) but it doesn’t work.

Hi,

IIRC, CSC is for compounds only, so you should put all your items into a single TEveCompound.

You probably also have to set selection mode to “master” (this is compounds and possible projectable parents):
gEve->GetSelection()->SetPickToSelect(TEveSelection::kPS_Master);
gEve->GetHighlight()->SetPickToSelect(TEveSelection::kPS_Master);

If you can’t get it to work, make me a simple example and I’ll fix it for you.

Cheers,
Matevz

Hi,
I added track and hits to compound object, but still - when I set point only point is highlighted, if I set track - only track is highlighted.

Hmmh, did you also set the SetPickToSelect()? Can you post a reporoducer, please?

Cheers,
Matevz
