QProgressDialog：如何調整對話框的大小以適合其內容？

Question

我用下面的代碼進行測試：

QProgressDialog* dialog = new QProgressDialog("Message", "Close", 0, 10); 
dialog->setWindowTitle("Long Long Long Long Title"); 
dialog->setCancelButtonText("Long Long Long Click this button to cancel"); 
dialog->setWindowModality(Qt::ApplicationModal); 
dialog->adjustSize(); 
dialog->setValue(5); 

標題和取消按鈕上的文字被切斷。我調用了adjustSize（），但它不起作用。如何調整對話框的大小以適應其內容？

您可以使用以下方法：使用QLayout ...

QProgressDialog* dialog = new QProgressDialog("Message", "Close", 0, 10); 
dialog->setWindowTitle("Long Long Long Long Title"); 
dialog->setCancelButtonText("Long Long Long Click this button to cancel"); 
dialog->setWindowModality(Qt::ApplicationModal); 
dialog->setValue(5); 

QVBoxLayout *layout = new QVBoxLayout; 
foreach (QObject *obj, dialog->children()) { 
    QWidget *widget = qobject_cast<QWidget *>(obj); 
    if (widget) 
     layout->addWidget(widget); 
} 
dialog->setLayout(layout);
