PyQT标签的鼠标悬停事件过滤器 [英] Mouseover event filter for a PyQT Label

问题描述

我一直在尝试转换示例这里使用一个简单的标签.

I've been trying to convert the example here to work with a simple label.

代码如下:

class mouseoverEvent(QtCore.QObject):
    def __init__(self, parent):
        super(mouseoverEvent, self).__init__(parent)
    def eventFilter(self, object, event):
        if event.type() == QtCore.QEvent.MouseMove:
            print "mousemove!"

self.filter = mouseoverEvent(self)
self.label.installEventFilter(self.filter)

现在奇怪的是，它确实有效，但是在我的控制台中没有"mousemove！"垃圾邮件的情况下(良好)以及错误: TypeError:mouseoverEvent.eventFilter()中无效的结果类型

Now curiously, this actually works, but not without my console being spammed with "mousemove!" (good) as well as the error: TypeError: invalid result type from mouseoverEvent.eventFilter()

我还没有弄清楚事件之间的复杂关系，所以这对我来说有点希腊.那么，有什么用呢?

I've not quite figured out the complex relationship between events yet, so this is a bit greek to me. So, what gives?

谢谢.

推荐答案

我相信您需要从eventFilter返回True或False，以表明您是否已完全处理事件.

I believe you need to return True or False from the eventFilter, to indicate whether you have handled the event completely or not.
