qt icon状态
在qt designer中我们可以看到，一些控件允许设置图标，然后在它下面会出现很多项目
对这些不同项目的解释见 enum QIcon::Mode
| Constant | Value | Description |
|---|---|---|
| QIcon::Normal | 0 | Display the pixmap when the user is not interacting with the icon, but the functionality represented by the icon is available. 控件可用时，如果没有检测到交互事件（如鼠标事件），显示该图标 |
| QIcon::Disabled | 1 | Display the pixmap when the functionality represented by the icon is not available.控件禁用时，显示该图标 |
| QIcon::Active | 2 | Display the pixmap when the functionality represented by the icon is available and the user is interacting with the icon, for example, moving the mouse over it or clicking it. 控件可用时，并且检测到交互事件（如鼠标事件），显示该图标 |
| QIcon::Selected | 3 | Display the pixmap when the item represented by the icon is selected. 控件被选中时（如check），显示该图标 |
