在Qt中,如果你想要修改`QMessageBox::information`窗口中的字体大小,你可以通过创建自定义的消息框或者使用`setWindowFont()`函数来设置。以下是两个示例:
1. **创建自定义消息框**:
首先,你需要创建一个`QDialog`或`QWidget`作为基础,并在其上添加`QLabel`或者其他显示文本的控件。然后设置这个控件的字体。例如:
```cpp
QFont customFont("Arial", 24); // 更大的字体尺寸
QLabel *messageLabel = new QLabel("这是自定义信息", this);
messageLabel->setFont(customFont);
QMessageBox::information(this, "标题", QWidget::window()->layout()->addWidget(messageLabel));
```
2. **使用`setWindowFont()`**:
如果你想保持使用`QMessageBox::information`的原生样式,但想改变字体,可以在消息框创建之后动态调整其窗口字体:
```cpp
QMessageBox msg(QMessageBox::Information, "标题", "这是信息");
msg.setWindowTitle("修改字体的消息");
msg.setFont(customFont);
msg.exec();
```
记得在实际应用中,确保`customFont`已正确导入并指向你所需的字体。
