如何将更改应用于适合特定名称模式的多个 ui 控件？

ui->Pipe_1->setStyleSheet(ui->Pipe_1->property("defaultStyleSheet").toString() +
" QProgressBar::chunk { background: #D7DF01; }");
ui->Pipe_2->setStyleSheet(ui->Pipe_2->property("defaultStyleSheet").toString() +
" QProgressBar::chunk { background: #D7DF01; }");
ui->Pipe_3->setStyleSheet(ui->Pipe_3->property("defaultStyleSheet").toString() +
" QProgressBar::chunk { background: #D7DF01; }");
ui->Pipe_4->setStyleSheet(ui->Pipe_4->property("defaultStyleSheet").toString() +
" QProgressBar::chunk { background: #D7DF01; }");
ui->Pipe_5->setStyleSheet(ui->Pipe_5->property("defaultStyleSheet").toString() +
" QProgressBar::chunk { background: #D7DF01; }");
ui->Pipe_6->setStyleSheet(ui->Pipe_6->property("defaultStyleSheet").toString() +
" QProgressBar::chunk { background: #D7DF01; }");
ui->Pipe_7->setStyleSheet(ui->Pipe_7->property("defaultStyleSheet").toString() +
" QProgressBar::chunk { background: #D7DF01; }");

我有这种代码，我想采用 for 循环来减少我的代码。管道是以下实例QProgressBar.

我尝试过：

for(x=1; x<75; x++){
QString y="Pipe_&d,x";
ui->Pipe_1->setObjectName(y);
ui->Pipe_1->setStyleSheet(ui->Pipe_1->property("defaultStyleSheet").toString() +
        " QProgressBar::chunk { background: #D7DF01; }");
}

但它不起作用我该如何处理？谢谢您的回答...

您可以很容易地找到与特定名称模式匹配的所有子项：

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

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