提高QT QEvent :: WindowActivate事件 [英] Raising a QT QEvent::WindowActivate event

问题描述

以下是上一个问题。

我有一个Qt对话框窗口，其中包含一个 QPlainTextEdit ，为此我创建了一个软件输入面板（SIP），下面的例子这里。在该示例中，输入小部件 QPlainTextEdit ，必须单击两次才能显示SIP。这是因为（见示例）没有引发 QEvent :: WindowActivate 事件，点击了 QPlainTextEdit 。

I've got a Qt dialog window that contains a QPlainTextEdit widget, for which I've created a Software Input Panel (SIP), following the example here. In this example an input widget, e.g. QPlainTextEdit, must be clicked twice in order for the SIP to appear. This is because (see example) a QEvent::WindowActivate event is not raised the QPlainTextEdit is clicked.

我考虑的解决方法是在 QPlainTextEdit时产生 QEvent :: WindowActivate 获得焦点。因此，我想知道如何可以提出 QEvent :: WindowActivate 事件以及如何做 - 假设解决方法有意义。

The workaround that I'm considering is to raise a QEvent::WindowActivate event when a QPlainTextEdit gets focus. Therefore I'd like to know how if it is possible to raise a QEvent::WindowActivate event and how to do so -- assuming the workaround makes sense.
