PyQt QPlainTextEdit：如何用组合键替换右键单击

Question

如何用组合键（例如 Ctrl-S）替换以下代码段中的 "right-click"？我搜索了 google 和 Qt 手册，但仍然不知道该怎么做。我是 Qt 的新手。任何帮助将不胜感激。

(P.S。致@ekhumoro：在你对“PyQt: How to insert text at the cursor in QTableView”问题的回答中，我似乎无法@你。我在这里使用了你的想法。但我想使用组合键或按钮。）

class MyDelegate(QStyledItemDelegate):
    contextMenuRequested = pyqtSignal(object, QPoint)

    def __init__(self, parent=None):
        super(MyDelegate, self).__init__(parent)

    def createEditor(self, parent, option, index):
        editor = QPlainTextEdit(parent)
        editor.setContextMenuPolicy(Qt.CustomContextMenu)
        editor.customContextMenuRequested.connect(
            self.commitAndCloseEditor)  # !!! right-click

    def commitAndCloseEditor(self):
        pass

您可以使用 QShortCut:

class MyDelegate(QStyledItemDelegate):
    def __init__(self, parent=None):
        super(MyDelegate, self).__init__(parent)
        self.shortcut = QtGui.QShortcut(
            QtGui.QKeySequence('Ctrl+S'), parent)
        self.shortcut.activated.connect(self.commitAndCloseEditor)

    def createEditor(self, parent, option, index):
        editor = QPlainTextEdit(parent)
        return editor
