calibration\_win\_t是[window\_base\_t](window_base_t.md)的子类控件，
|
|
|
|
|
|
window\_base\_t的函数均适用于calibration\_win\_t控件。
|
|
|
|
|
|
|
|
|
|
|
|
在xml中使用"calibration\_win"标签创建电阻屏校准窗口。如：
|
|
|
|
|
|
|
|
|
|
|
|
```xml
|
|
|
|
|
|
<calibration_win name="cali" w="100%" h="100%" text="Please click the center of cross">
|
|
|
|
|
|
</calibration_win>
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|

[window.xml](https://github.com/zlgopen/awtk/blob/master/demos/assets/raw/ui/calibration_win.xml)
|
|
|
|
|
|
|
|
|
|
|
|
在c代码中使用函数calibration\_win\_create创建窗口。如：
|
|
|
|
|
|
|
|
|
|
|
|
```c
|
|
|
|
|
|
widget_t* win = calibration_win_create(NULL, 0, 0, 320, 480);
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
通过calibration\_win\_set\_on\_done注册回调函数，用于保存校准数据。
