如何为可编辑的QComboBox覆盖KeyPressEvent? [英] How-to override KeyPressEvent for an editable QComboBox?

问题描述

我有一个名为ValidableComboBox的类，直接从QComboBox派生.

I have a class named ValidableComboBox that derives directly from QComboBox.

每个ValidableComboBox实例都将setEditable()设置为true.我的目标是添加一些信号，只要有人按下QComboBox中的回车键，就会发出该信号.

Every instance of ValidableComboBox has setEditable() set to true. My goal is to add some signal that will be emitted whenever someone presses return key in the QComboBox.

为此，我在ValidableComboBox中重新实现了void KeyPressEvent(QKeyEvent* e).但是，当我在组合框中键入内容时，似乎永远都不会调用它.

To do so, I reimplemented void KeyPressEvent(QKeyEvent* e) in ValidableComboBox. However, it seems that it never gets called when I type something into the combobox.

有没有办法实现这一目标?我所做的事情可能出什么问题了?

Is there a way to achieve this ? What could possibly be wrong with what I have done ?

谢谢.

推荐答案

您似乎在kode中使用的功能具有Kapital K，而不是小k，好吗? :-D

The funktion you've seem to be using in your kode has a Kapital K, instead of a small k, ok? :-D
