## Qt学习笔记与代码
阅读《Qt5 开发与实例》过程中记录Qt学习过程中一些笔记以及相应的代码
1. 计算圆面积: Dialog
**Note**: 书中P15页代码笔误：
```cpp
ui->areaLabel_2->setText(tempStr.setNum(area));
```
应更正为：
```cpp
ui->radiusLabel->setText(tempStr.setNum(area));
```
2015年7月17日读完第一章。
2. QHash类：STL风格迭代器。
3. 控件：按钮组。`setGeometry(x, y, w, h)`，`(x, y)`表示左上顶点。
**Note**: P56页:
```cpp
connect(quit, SINAL(clicked()), aApp, SLOT(quit()))
```
中`qApp`所指得槽对象是哪个？
