当主窗体失去焦点时，HardwareButton键事件丢失 [英] HardwareButton key events lost when main form looses focus

问题描述

我在WM5应用程序中使用的是硬件按钮，几乎完全按照文档所说的那样顺利运行，直到.....你的主要形式失去对一个（子）按钮的焦点（位于主要形式）。

我也尝试将焦点重新恢复到主窗体但是调用它。从定时器上调用它主要是不起作用 - 可能是线程问题（？）。

提前感谢任何提示！

I am using HardwareButtons in a WM5 app pretty much exactly along the lines the doc says and it works well until.....
the main form looses focus that goes to a (child) button (located on the main form).

Also I tried to reinstate focus to the main form but calling this.Activate() on it main from a timer seems not to work - possibly a thread issue (?).

Thanks ahead for any hints!

推荐答案

不确定是否通过HardwareButtons表示实际按钮或某些按钮一种组件。如果是前者，将表单的KeyPreview属性设置为true通常会达到预期的效果。

Not sure whether by HardwareButtons you mean actual buttons or some kind of component. If it's the former, setting form's KeyPreview property to true usually works to the desired effect.
