ui->groupBox->layout()->addWidget(newButton);用不了

这里的问题可能是您没有设置布局。...layout->addWidget(newButton); ui->groupBox->setLayout(layout); 这将创建一个垂直布局，并将其设置为 groupBox 的布局，然后将新按钮添加到该布局中。

要实现显示圆形的好友头像并减小列表项的高度，你可以按照以下步骤修改...item->setSizeHint(QSize(widget->sizeHint().width(), 80)); 通过以上步骤的修改，你可以实现显示圆形的好友头像并减小列表项的高度。

要确保QLabel的大小能够完全...storage_path->setMinimumWidth(columnWidth / 2); 这将设置storage_path标签的最小宽度为列宽的一半。通过这些修改，您应该能够确保QLabel的大小能够完全显示其文本内容。
