QWebEngineView, post 视图内的KeyEvents

Question

我有自己的"Virtual Keyboard"。我已经将点击的按钮转换为 KeyEvents 并将其传递给 QTextEdit 等等。我现在的问题是我想对 QWebEngineView 内的可写区域做同样的事情。

例如，我用我的键盘编辑我的QLineEdit，并请求一个网站。完成

假设我请求了 google。现在 Google 网站就在我面前。我需要将 KeyEvents 从我的键盘发送到它的搜索框。（我的 QWebEngineView 内的框。

现在说几点：

我正在使用 PyQt5
正如我所读，API 告诉我它的父级应该将 KeyEvent 消耗到正确的位置。 here
这个片段说“......就像使用 QtWebKit 一样。”
我现在看到 QtWebKit 已经没有了，所以 Chromium 代替了。（也许这就是我没有参加这些活动的原因 post )

这就是我所拥有的，例如，将 KeyEvents 模拟到我的 QEditText 等等..

from PyQt5.QtCore import QCoreApplication
from PyQt5.QtCore import QEvent
from PyQt5.QtCore import QSize
from PyQt5.QtCore import Qt
from PyQt5.QtGui import QIcon
from PyQt5.QtGui import QKeyEvent
from PyQt5.QtGui import QPixmap
from PyQt5.QtWidgets import QPushButton


class KeyboardKey(QPushButton):

    __path = ""

    __size = [30, 30]
    __style = ""
    __icon_on = ""
    __icon_off = ""
    __auto_repeat = True
    __receiver = None
    __key = None
    __str_key = None

    def __init__(self, style, str_icon_on, str_icon_off, auto_repeat, size, receiver, key, str_key):
        super(KeyboardKey, self).__init__()
        self.__size = size
        self.__style = style
        self.__icon_on = str_icon_on
        self.__icon_off = str_icon_off
        self.__auto_repeat = auto_repeat
        self.__receiver = receiver
        self.__key = key
        self.__str_key = str_key
        self.set_up_button(style, str_icon_on, str_icon_off, auto_repeat, size, receiver, key, str_key)

    def set_up_button(self, style, str_icon_on, str_icon_off, auto_repeat, size, receiver, key, str_key):
        self.__size = size
        self.__style = style
        self.__icon_on = str_icon_on
        self.__icon_off = str_icon_off
        self.__auto_repeat = auto_repeat
        self.__receiver = receiver
        self.__key = key
        self.__str_key = str_key
        self.setText(str_key)

        self.setFixedSize(size[0], size[1])
        self.setStyleSheet(style)
        self.setIconSize(QSize(size[0], size[1]))
        self.setIcon(QIcon(self.__path + str_icon_off + ".png"))
        self.setAutoRepeat(auto_repeat)
        pixmap = QPixmap(self.__path + str_icon_off + ".png")
        self.setMask(pixmap.mask())
        self.pressed.connect(self.key_pressed)
        self.released.connect(self.key_released)

    def set_receiver(self, receiver):
        self.__receiver = receiver

    def key_pressed(self):
        self.setStyleSheet("""
                            border-width: 5px;
                            border-color: rgb(37,43,52);
                            color: white;
                            background-color: rgb(0,187,255);
                        """,)

    def key_released(self):
        event = QKeyEvent(QEvent.KeyPress, Qt.Key_A, Qt.NoModifier,
                          "a", False)
        # self.__receiver is my QEditText/QLineEdit/...
        self.__receiver.keyPressEvent(event)

最后一部分是我 post 我在 "self.__receiver" 上的活动。此接收器始终为调用它的 "QWidget" 设置。

我试过只说类似的话：

def key_released(self):
    event = QKeyEvent(QEvent.KeyPress, Qt.Key_A, Qt.NoModifier,
                      "a", False)
    # web_view is my QWebEngineView... but it won't consume. Or maybe it's not consuming to the right place.
    self.web_view.keyPressEvent(event)

Answer 1

当您将事件发送到 QWebEngineViews focusProxy 时，这应该可以工作 - 这样的事情应该可以工作：

recipient = self.web_view.focusProxy()
QApplication.postEvent(recipient, event)

QWebEngineView, post 视图内的KeyEvents

QWebEngineView, post KeyEvents inside the View
