示例1: initProgressBinding

private void initProgressBinding() {
DoubleExpression tmp = constantOf(0);
for (Command command : registeredCommands) {
final ReadOnlyDoubleProperty progressProperty = command.progressProperty();
/**
* When the progress of a command is "undefined", the progress property has a value of -1.
* But in our use case we like to have a value of 0 in this case.
* Therefore we create a custom binding here.
*/
