|
||
* system\_bar窗口。
|
||
*
|
||
* system\_bar窗口是一种特殊的窗口，独占LCD顶部区域，用来显示当前窗口的标题和关闭按钮等内容。
|
||
*
|
||
*> system\_bar窗口需要在打开第一个应用程序窗口之前打开。
|
||
*
|
||
* system_bar对两个子控件会做特殊处理：
|
||
*
|
||
* * 1.名为"title"的label控件，自动显示当前主窗口的name或text。
|
||
* * 2.名为"close"的button控件，点击之后向当前主窗口发送EVT\_REQUEST\_CLOSE\_WINDOW消息。
|
||
*
|
||
*system\_bar\_t是[window\_base\_t](window_base_t.md)的子类控件，
|
||
* window\_base\_t的函数均适用于system\_bar\_t控件。
|
||
*
|
||
* 在xml中使用"system\_bar"标签创建system\_bar窗口。如：
|
||
*
|
||
* ```xml
|
||
* <system_bar h="30">
|
||
* <column x="0" y="0" w="-40" h="100%">
|
||
* <label style="title" x="10" y="m" w="55%" h="100%" name="title"/>
|
||
* <digit_clock style="time" x="r" y="m" w="40%" h="100%" format="hh:mm"/>
|
||
* </column>
|
||
* <button style="close" x="r:5" y="m" w="26" h="26" name="close" text="x"/>
|
||
* </system_bar>
|
||
* ```
|
||
*
|
||
* > 更多用法请参考：
|
||
* [system_bar](https://github.com/zlgopen/awtk/blob/master/design/default/ui/system_bar.xml)
|
||
*
|
||
* 在c代码中使用函数system\_bar\_create创建system\_bar窗口。如：
|
||
*
|
||
* ```c
|
||
* widget_t* win = system_bar_create(NULL, 0, 0, 320, 30);
|
||
* ```
|
||
*
|
||
* > 创建之后，和使用普通窗口是一样的。
|
||
*
|
||
* 可用通过style来设置控件的显示风格，如背景颜色等等。如：
|
||
*
|
||
* ```xml
|
||
* <system_bar>
|
||
* <style name="default">
|
||
* <normal bg_color="#a0a0a0"/>
|
||
* </style>
|
||
* </system_bar>
|
||
* ```
|
||
*
|
||

|
||
* [system_bar.xml](https://github.com/zlgopen/awtk/blob/master/design/default/styles/system_bar.xml)
