|

|
|
* 滑块控件。
|
|||
|
|
*
|
|||
|
|
* slider\_t是[widget\_t](widget_t.md)的子类控件，widget\_t的函数均适用于slider\_t控件。
|
|||
|
|
*
|
|||
|
|
* 在xml中使用"slider"标签创建滑块控件。如：
|
|||
|
|
*
|
|||
|
|
* ```xml
|
|||
|
|
* <slider x="center" y="10" w="80%" h="20" value="10"/>
|
|||
|
|
* <slider style="img" x="center" y="50" w="80%" h="30" value="20" />
|
|||
|
|
* <slider style="img" x="center" y="90" w="80%" h="30" value="30" min="5" max="50" step="5"/>
|
|||
|
|
* ```
|

|
*

|
|
* > 更多用法请参考：
|
|||
|
|
* [basic](https://github.com/zlgopen/awtk/blob/master/design/default/ui/basic.xml)
|
|||
|
|
*
|
|||
|
|
* 在c代码中使用函数slider\_create创建滑块控件。如：
|
|||
|
|
*
|
|||
|
|
* ```c
|
|||
|
|
* widget_t* slider = slider_create(win, 10, 10, 200, 30);
|
|||
|
|
* widget_on(slider, EVT_VALUE_CHANGED, on_changed, NULL);
|
|||
|
|
* widget_on(slider, EVT_VALUE_CHANGING, on_changing, NULL);
|
|||
|
|
* ```
|
|||
|
|
*
|

|
|
* > 完整示例请参考：

* [slider demo](https://github.com/zlgopen/awtk-c-demos/blob/master/demos/slider.c)
|
|||
|
|
*
|
|||
|
|
* 可用通过style来设置控件的显示风格，如图片和颜色等等。如：
|
|||
|
|
*
|
|||
|
|
* ```xml
|
|||
|
|
* <style name="img" bg_image="slider_bg" fg_image="slider_fg">
|
|||
|
|
* <normal icon="slider_drag"/>
|
|||
|
|
* <pressed icon="slider_drag_p"/>
|
