eventFilter监控鼠标动作，请教

[tt2com]

bool Vrf_home::eventFilter(QObject *obj, QEvent *ev)
{
	if (obj==home_ui.monitor)
	{
		if (ev->type()==QEvent::MouseButtonRelease)
		{
			home_ui.monitor->setGeometry(QRect(55, 123, 106, 106));
			home_ui.monitor->setStyleSheet(QString::fromUtf8("border-image: url(:/test_memory/Resources/monitor.png);"));
			return true;
		}
		if (ev->type()==QEvent::MouseButtonPress)
		{
			home_ui.monitor->setGeometry(QRect(55-14, 123-14, 106+28, 106+28));
			home_ui.monitor->setStyleSheet(QString::fromUtf8("border-image: url(:/test_memory/Resources/monitor_light.png);"));
			return true;
		}
	}
	return QWidget::eventFilter(obj, ev);
}

我的按键是非标准的上面有不少其他信息，使用我用一个label作为一个鼠标响应区别，我按上面的方法来获取鼠标的按下和是否动作，但如果鼠标按的快一些，无法全部响应。我还如何改。

响应一次丢一次

哪位来教教我啊

[圆圆胖胖的车车]

不可能丢啊。。丢了就推翻了我Qt的知识了哈。。。

你确定你点在了你安装的filter那个Widget上了？

肯定安装了不然不会响应啊，我现在如果鼠标按键按的稍微快一点就会响应不到，我想知道为什么？

我测试了下，每次都能响应，但按下和弹起的图片是有变化的，在界面上显示不出来。
也就是说鼠标连续动作，按键响应了，但图像上面则丢掉了一些，我该如何处理？

QEvent::MouseButtonRelease 所有数据均能打印出来，
但 QEvent::MouseButtonPress的数据有不是每次都能打印，哪位指导下问题出现在那边？

[圆圆胖胖的车车]

呵呵。。 点快了。可能出现double clicked....

if( obj == ui->pushButton && e->type() == QEvent::MouseButtonPress)
{
qDebug() << "mouse press";
}

if( obj == ui->pushButton && e->type() == QEvent::MouseButtonRelease)
{
qDebug() << "mouse releaes";
}

if( obj == ui->pushButton && e->type() == QEvent::MouseButtonDblClick)
{
qDebug() << "mouse double clicked";
}
