请问，buiw,propcontainer下insert一个textwidget的问题。

[qingqing2300]

我在propcontainer下insert一个textwidget。运行模拟器，每次按下手机模拟器按键时，都没有反应，不能键入字符。
不知道为何？

我还在textwidget中自定一个TextWdgHandleEvent函数。
但是也是接收不到按键事件。

请问该添加什么语句啊？

多谢帮忙!

嗯，
我把propcontainer 放到了viewport里了，在viewport事件处理里在添加一个propcontainer的处理函数。这样就能正常处理事件了。谢谢啊！

请问，propcontainer 我设置了WIDGET_KEEP_EXTENT，LAYOUT_HORZ显示，并向里边insert了两个widget，分别是imgwdg,textwidget，两个大小不同。结果显示出来textwidget的高跟imgwidget一样了。怎么设置函数才可以正常显示啊？谢谢关注！

我在网上的资料中看到关于 propcontainer

“在PropContainer中的widget可以被垂直放置也可以被水平放置。
如果被水平放置，widget的上下边缘将被设置成容器的高度和vice-versa。“

是这样吗？ 是否可以修改以显示不同大小的widget在propcontainer中。

谢谢！
