Method Details [hide private]

onAddCmdToViewer(self)

source code 
method called when an instance of this command is added to the viewer. This enable viewer-addition time initializations
Overrides: ViewerFramework.VFCommand.Command.onAddCmdToViewer
(inherited documentation)

setupUndoBefore(self, atom1, atom2)

source code 
This method builds the self.undoCmds string. This method should have the same signature than the __call__. When this string is executed it should undo the actions of this command. This string will be appended to the undoCmdStack list if the command is successfuly carried out. This method handles only commands with the negateKw. Other commands have to overwrite it.
Overrides: ViewerFramework.VFCommand.Command.setupUndoBefore
(inherited documentation)

__call__(self, atom1, atom2, **kw)
(Call operator)

source code 

None<-removeBonds(atom1, atom2)

atom1 : first atom

atom2 : second atom
Overrides: ViewerFramework.VFCommand.Command.__call__

doit(self, atom1, atom2)

source code 
virtual method. Has to be implemented by the sub classes
