关于STemWin如何回到指定窗口

Julius0072008 · 发表于 2020-1-2 20:16:44

尝试建立了以桌面窗口为父窗口A,然后父窗口下建立了子窗口B，子窗口B下再次建立了窗口C，目前调试发现，窗口C删除后返回偶尔是A窗口，偶尔是B窗口。不知道为什么返回到的不是各自的父窗口，一级一级返回去。 1.有什么方法可以指定返回到某个窗口吗？
2.emWin的运行机制是怎么样的？
比如在父窗口A回调函数内部按钮动作下创建子B窗口（非阻塞），然后B窗口显示，LCD就显示A窗口，然后就一直运行B窗口还是从A窗口函数回调函数break退出到按顺序执行？
对于没有操作系统的：还是程序一直按着while(1)里面的结构顺序执行，但是B窗口是有默认的焦点窗口，最上面的窗口，其他窗口在下面，有什么输入都是B窗口接收。请版主大概说一下，运行机制最重要，一直没有想清楚窗口之间怎么调用的。

方便的话，直接上代码，我帮你简单修改下。

仅需emWin部分的代码即可

上面界面B代码（是界面A的子窗口）建立了三个按钮，按钮进入不同的分支功能界面C(是B界面的子窗口，A界面的孙窗口）；
1.三个功能界面怎么设置退出之后，指定返回至A或者B界面？
2.孙窗口C可以相应WM_KEY消息进行ESC退出关闭界面，但是B里面总是不能相应WM_KEY消息退出到A界面，如果没有按下按钮，可以响应，按下按钮之后，B窗口就不能响应WM_KEY了。
3.我用的是PC端模拟器，按下的是电脑ESC进入WM_KEY

窗口有个Z轴，就是好几个窗口的覆盖顺序。 C关闭后，回到到哪个，取决于c的下面是哪个窗口。

查看是有Z位置，但是没有具体的设置，好像只有设置为底部，设置为顶部位置，那顶部关闭之后，就不知道哪个窗口在次顶部位置了。
是不是在WM_DELETE信息那里设置把需要返回到的窗口设置为顶部？
Z位置设置函数查找了，没有这个设置函数？
