Tango ATK Tutorial

The code sample below can be used for these two viewers indifferently:
ICommand ic;
CommandList cmdl = new CommandList();
VoidVoidCommandViewer vvcv = new VoidVoidCommandViewer();
Try
{
ic = (ICommand)cmdl.add("elin/gun/beam/Off");
vvcv.setAttModel(ic);
}
catch (Exception ex)
{
System.out.println("Cannot connect device");
ex.printStackTrace();
}
Commands with DevBoolean input argument and no output argument
(BooleanVoidCommand)
The commands with DevBoolean input argument and no output argument are called
BooleanVoid commands in ATK. The following list presents all the command viewers
suitable for BooleanVoidCommands:
1. OnOffCheckBoxCommandViewer: is a sub-classes of swing JCheckBox. A click on a
OnOffCheckBoxCommandViewer will immediately execute the corresponding
command on the tango device. The value of the input parameter passed to the device
command depends on the state of the checkBox. If the checkBox is selected the device
command is called with “true” parameter, otherwise the “false” parameter is sent to
the command.
2. OnOffSwitchCommandViewer: A click on a OnOffSwitchCommandViewer will
immediately execute the corresponding command on the tango device. The value of
the input parameter passed to the device command depends on the state of the switch.
The difference with the previous viewer is only in the graphical representation.
