如何在Qt4.8中创建滑动效果？
我需要创建一个屏幕，用户将左右滑动，上下滑动，并在每个屏幕上显示另一个屏幕。它就像一个十字，中心和两端是系统的另一个屏幕 我尝试使用GestureArea，但它唯一有效的事件是onTapAndHold，其他事件如onSwipe不会运行。后来我发现Qt4.8在GestureArea中有一个bug，其他事件都不起作用。问题是onTapAndHold事件也会在单击时运行，我只希望它与滑动事件一起运行 完成 我是如何做到的：如何在Qt4.8中创建滑动效果？,qt,qml,swipe,gesture,Qt,Qml,Swipe,Gesture,我需要创建一个屏幕，用户将左右滑动，上下滑动，并在每个屏幕上显示另一个屏幕。它就像一个十字，中心和两端是系统的另一个屏幕 我尝试使用GestureArea，但它唯一有效的事件是onTapAndHold，其他事件如onSwipe不会运行。后来我发现Qt4.8在GestureArea中有一个bug，其他事件都不起作用。问题是onTapAndHold事件也会在单击时运行，我只希望它与滑动事件一起运行 完成 我是如何做到的： import QtQuick 1.1 import Qt.labs.gestu

好。。。在检查了我上面使用的GestureArea导致的错误行为后，因为它们对点击onTapAndHold事件做出响应，而我只是想知道刷卡事件的答案，所以我决定删除它们并使用MouseArea进行刷卡模拟 刷卡操作有了很大的改进，GestureArea提出的点击事件问题已经得到解决，但导致了MouseAreas覆盖问题 这在使用GestureArea时不存在，因为它不会阻止单击位于其下方的鼠标earea，而鼠标eareas重叠会阻止它 无论如何，我在下面描述的GestureArea刷卡事件的解决方案：

我正在检查一种处理MouseAreas覆盖的方法。对我来说，它给出了一个错误：没有安装模块“Qt.labs.signatures”。@msribeir用于Qt 5。8@JimitRupani我的解决方案是Qt4.8。我知道GestureArea在Qt 5中已停止使用（这就是为什么会出现此错误消息），并已被PinchArea取代，但我从未使用过它，因此我不知道它是否以相同的方式工作。对我来说，它给出了此错误：未安装模块“Qt.labs.birters”。@msribeir用于Qt 5。8@JimitRupani我的解决方案是Qt4.8。我知道GestureArea在Qt5中已停止使用（这就是为什么会出现此错误消息），并已被PinchArea取代，但我从未使用过它，因此我不知道它是否以相同的方式工作。
