Hello, actually some stuff was moved from the ghemical source tree into libghemical source tree. I have been doing some work on molecular dynamics lately (pressure control) and therefore some stuff has been moving around. Please do cvs update -d -P for your both (ghemical and libghemical) working copies. Regards, Tommi PS: today I removed AtomUpdateAllItems() since the solution I suggested yesterday seems to work in both branches. So now from the atom list in "project view" one can set an atom locked (using the popup-menu) and set an atom frozen (using the checkbutton). The checkbutton-method is clearly more infromative, so now it would be cool to have two checkbuttons, one for selection and one for freezing. We don't need to remove the popup menu, let it just leave there as a code example that can have better use later. If you still wish to work on "project view", the checkbutton for selection would be nice. I could add into graphics code something that makes frozen atoms visible ; any ideas how to render the frozen atoms?
