QWebEngineView，在視圖中發佈KeyEvents

Question

我有我自己的「虛擬鍵盤」。我已經將單擊到KeyEvents的按鈕轉換爲QTextEdit等等。我現在的問題是我想對QWebEngineView中的可寫區域執行相同的操作。

例如，我用我的鍵盤編輯我的QLineEdit，並請求一個網站。 DONE

比方說，我要求谷歌。現在我的Google網站就在我的面前。我需要從我的鍵盤發送的KeyEvents到它的搜索框（盒這是我的QWebEngineView內

現在讓我們點了幾個要點：。

1. 我使用PyQt5
2. 正如我讀過的API說我，這是家長要消耗該KeyEvent到corect地方。here
3. 這個片段說：‘......就像是可能的QtWebKit的。’
4. 我已經看到現在沒有更多的QtWebKit，所以Chromium代替了。（也許這是我沒有得到發佈這些事件的原因）

這是我必須例如模擬的KeyEvents我QEditText和任何..

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) 

這最後一部分是我在「self .__ receiver」上發佈我的活動的一部分。該接收器始終爲調用它的「QWidget」設置。

我曾嘗試只是這樣說：當您發送事件到QWebEngineViews focusProxy代替

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

這應該工作 - 這樣的事情應該工作：

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