OK,

if have it running

But the problem now is, when i have multiple objects with lines connected, my CPU is around 80% increasing.

The only way i can do in the moment is to close the apllication, so my CPU is ddecreasing to (0 - 10 % ==> normal CPU usage).

Whats going on there?
If also noticed that the paint event in the "arrow.cpp" is called to often.

Can anybody help me?
