Python 模拟鼠标拖动事件PyQt5

我正在制作一个自动点击QWebEngineView小部件的机器人

我想模拟一个鼠标拖动到那个小部件上

即：-

• 在QPoint（100100）上按鼠标左键btn

• 将鼠标移动到QPoint（500500）

• 释放鼠标左键

我尝试了此代码，但不起作用：

def drag_from_to(browser_widget, x1, y1, x2, y2):

    for child in browser_widget.findChildren(QtWidgets.QWidget):
        if (child.metaObject().className() == "QtWebEngineCore::RenderWidgetHostViewQtDelegateWidget"):
            #I also tried sending the event to 'browser_widget' instead of 'child'
            event_press = QtGui.QMouseEvent(QtCore.QEvent.MouseButtonPress, QtCore.QPoint(x1, y1),
                                            QtCore.Qt.LeftButton, QtCore.Qt.LeftButton, QtCore.Qt.NoModifier, )
            QtCore.QCoreApplication.postEvent(child, event_press)

            event_move = QtGui.QMouseEvent(QtCore.QEvent.MouseMove, QtCore.QPoint(x2, y2),
                                           QtCore.Qt.LeftButton, QtCore.Qt.LeftButton, QtCore.Qt.NoModifier, )
            QtCore.QCoreApplication.postEvent(child, event_move)

            event_release = QtGui.QMouseEvent(QtCore.QEvent.MouseButtonRelease, QtCore.QPoint(x2, y2),
                                              QtCore.Qt.LeftButton, QtCore.Qt.LeftButton, QtCore.Qt.NoModifier, )
            QtCore.QCoreApplication.postEvent(child, event_release)
            return

编辑：我还尝试了QTest.mouseMove（）。。。它实际上移动了鼠标光标。。。但是，我想让机器人在后台运行。。。我希望用户能够在Bot运行时使用他的计算机

经过一些测试，我找到了解决方案：-

发布新QEvent.MouseMove后，我必须暂停代码执行至少1毫秒，我还必须将该事件顺序发送到两点之间的每一点[例如：将鼠标从QPoint（x1，y1）拖动到QPoint（x2，y2）]

以下是工作代码：

def wait(ms): QTest.qWait(ms) #pauses the code without freezing the UI
def getIntEquidistantPoints(x1, y1, x2, y2):
    n = int(((((x2 - x1 )**2) + ((y2-y1)**2))**0.5))
    def lerp(v0, v1, i): return v0 + i * (v1 - v0)
    return [(int(x), int(y)) for x,y in [(lerp(x1,x2,1./n*i), lerp(y1,y2,1./n*i)) for i in range(n+1)]]
def drag_from_to(browser_widget, x1, y1, x2, y2):
    x1 = int(x1);y1 = int(y1);x2 = int(x2);y2 = int(y2)
    for child in browser_widget.findChildren(QtWidgets.QWidget):
        if (child.metaObject().className() == "QtWebEngineCore::RenderWidgetHostViewQtDelegateWidget"):
            event_press = QtGui.QMouseEvent(QtCore.QEvent.MouseButtonPress, QtCore.QPoint(x1, y1),
                                            QtCore.Qt.LeftButton, QtCore.Qt.LeftButton, QtCore.Qt.NoModifier, )
            QtCore.QCoreApplication.postEvent(child, event_press)
            for p in getIntEquidistantPoints(x1, y1, x2, y2):
                QtCore.QCoreApplication.postEvent(child,
                                                  QMouseEvent(QEvent.MouseMove,
                                                              QtCore.QPoint(p[0], p[1]),
                                                              Qt.NoButton,
                                                              Qt.MouseButtons(Qt.LeftButton),
                                                              Qt.NoModifier)); wait(1)
            event_release = QtGui.QMouseEvent(QtCore.QEvent.MouseButtonRelease, QtCore.QPoint(x2, y2),
                                              QtCore.Qt.LeftButton, QtCore.Qt.LeftButton, QtCore.Qt.NoModifier, )
            QtCore.QCoreApplication.postEvent(child, event_release)

这回答了你的问题吗？不，QTest.mouseMove（）实际上移动鼠标光标。。。我想让机器人在后台运行。。。我希望用户能够在Bot运行时使用他的计算机
