## grid\_item\_t
|
|||
|
|
### 概述
|
|||
|
|
|
|||
|
|
|
|||
|
|
grid_item。一个简单的容器控件，一般作为grid的子控件。
|
|||
|
|
|
|||
|
|
它本身不提供布局功能，仅提供具有语义的标签，让xml更具有可读性。
|
|||
|
|
子控件的布局可用layout\_children属性指定。
|
|||
|
|
请参考[布局参数](https://github.com/zlgopen/awtk/blob/master/docs/layout.md)。
|
|||
|
|
|
|||
|
|
grid\_item\_t是[widget\_t](widget_t.md)的子类控件，widget\_t的函数均适用于grid\_item\_t控件。
|
|||
|
|
|
|||
|
|
在xml中使用"grid\_item"标签创建grid\_item。如：
|
|||
|
|
|
|||
|
|
```xml
|
|||
|
|
<grid x="0" y="0" w="100%" h="100%" children_layout="default(c=2,r=2,m=5,s=5)">
|
|||
|
|
<grid_item>
|
|||
|
|
<button x="c" y="m" w="80%" h="30" name="0" text="0"/>
|
|||
|
|
</grid_item>
|
|||
|
|
<grid_item>
|
|||
|
|
<button x="c" y="m" w="80%" h="30" name="1" text="1"/>
|
|||
|
|
</grid_item>
|
|||
|
|
<grid_item>
|
|||
|
|
<button x="c" y="m" w="80%" h="30" name="2" text="2"/>
|
|||
|
|
</grid_item>
|
|||
|
|
<grid_item>
|
|||
|
|
<button x="c" y="m" w="80%" h="30" name="3" text="3"/>
|
|||
|
|
</grid_item>
|
|||
|
|
</grid>
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
可用通过style来设置控件的显示风格，如背景颜色等。如：
|
|||
|
|
|
|||
|
|
```xml
|
|||
|
|
<style name="default" border_color="#a0a0a0">
|
|||
|
|
<normal bg_color="#f0f0f0" />
|
|||
|
|
</style>
|
|||
|
|
```
|
|||
