|
* 页面管理控件。
|
|||
|
|
*
|
|||
|
|
* 只有一个Page处于active状态，处于active状态的Page才能显示并接收事件。
|
|||
|
|
* 常用于实现标签控件中的页面管理。
|
|||
|
|
*
|
|||
|
|
* pages\_t是[widget\_t](widget_t.md)的子类控件，
|
|||
|
|
* widget\_t的函数均适用于pages\_t控件。
|
|||
|
|
*
|
|||
|
|
* 在xml中使用"pages"标签创建页面管理控件。如：
|
|||
|
|
*
|
|||
|
|
* ```xml
|
|||
|
|
* <tab_control x="0" y="0" w="100%" h="100%" >
|
|||
|
|
* <pages x="c" y="20" w="90%" h="-60" value="1">
|
|||
|
|
* ...
|
|||
|
|
* </pages>
|
|||
|
|
* <tab_button_group>
|
|||
|
|
* ...
|
|||
|
|
* </tab_button_group>
|
|||
|
|
* </tab_control>
|
|||
|
|
* ```
|
|||
|
|
*
|
