Answer 1

You can very easily find all children matching a certain name pattern:

// C++11
auto pipes = findChildren(QRegExp("Pipe_[0-9]+"));
for (pipe : pipes) {
  pipe->setStyleSheet(pipe->property("defaultStyleSheet").toString() +
    " QProgressBar::chunk { background: #D7DF01; }");
}

// C++98
QList pipes = findChildren(QRegExp("Pipe_[0-9]+"));
foreach (pipe, pipes) {
  pipe->setStyleSheet(pipe->property("defaultStyleSheet").toString() +
    " QProgressBar::chunk { background: #D7DF01; }");
}
