RViz SelectionManager ignore marker
Hi guys,
I'm playing around with rviz right now and want to place an interactive maker over another cylindrical interactive marker, so that i can select a height with the smaller marker. My problem now is that the bigger marker blocks the arrows to drag the smaller marker along the axis. I already deactivated all interactive marker controls and made the marker transparent but i still can't select the arrow.
After some research i found out that i have to change the picking scheme of the object i want to hide.
"Objects without picking scheme are reliably ignored by assigning a zero selection handle"
Can someone help me with that. I don't have much experience with C++ so its hard to figure it out on my own. By the way is it possible to "reactivate" the marker again after i have selected the height?
Cheers, Alex
EDIT: i found another similar question on the forum but it didnt really help me, since it is really abstract too http://answers.ros.org/question/52853/rviz-get-interactive-object-behind-transparent-object/
