python - 在两个 QTreeView 之间拖放

Question

我的目的是在两个QTreeView之间进行拖放。例如:将项目从本地 TreeView 拖到远程 TreeView ，远程 TreeView 将接受信号并触发一个功能(例如:打印一些东西，所以我知道它成功了)。

我搜索了一些帖子，他们只是用一个QTreeView来做，我仍然很困惑如何使用拖放。这是我的完整代码，包括 UI。

Answer 1

如果您在2个小部件之间交换数据，我建议使用QTreeWidget而不是QTreeView，因为QTreeWidget中的数据可以编辑动态数据，行和值(value)。在 2 个 QTreeWidget 之间拖放时，我们可以将它们等效为“复制和删除”。

很容易在2个QTreeWidget之间实现，您只需在QTreeWidget中拖动输入事件并复制到新的QTreeWidget时进行处理。 (如果您内部移动，我将自行删除旧数据)接下来，如果QTreeWidget之间有移动数据，请创建您自己的信号来处理它们。最后，将其集成到您的类或小部件中。

示例(不是您的代码，但您可以自己实现)，像这样；

import sys
from PyQt4 import QtCore, QtGui

class QCustomTreeWidget (QtGui.QTreeWidget):
    itemMoveOutActivated = QtCore.pyqtSignal(object)
    itemNewMoveActivated = QtCore.pyqtSignal(object)

    def __init__ (self, parent = None):
        super(QCustomTreeWidget, self).__init__(parent)
        self.setDragDropMode(QtGui.QAbstractItemView.InternalMove)

    def dragEnterEvent (self, eventQDragEnterEvent):
        sourceQCustomTreeWidget = eventQDragEnterEvent.source()
        if isinstance(sourceQCustomTreeWidget, QCustomTreeWidget) and (self is not sourceQCustomTreeWidget):
            eventQDragEnterEvent.accept()
        else:
            QtGui.QTreeWidget.dragEnterEvent(self, eventQDragEnterEvent)

    def dropEvent (self, eventQDropEvent):
        sourceQCustomTreeWidget = eventQDropEvent.source()
        if isinstance(sourceQCustomTreeWidget, QCustomTreeWidget) and (self is not sourceQCustomTreeWidget):
            sourceQTreeWidgetItem      = sourceQCustomTreeWidget.currentItem()
            destinationQTreeWidgetItem = sourceQTreeWidgetItem.clone()
            self.addTopLevelItem(destinationQTreeWidgetItem)
            sourceQCustomTreeWidget.itemMoveOutActivated.emit(destinationQTreeWidgetItem)
            self.itemNewMoveActivated.emit(destinationQTreeWidgetItem)
        else:
            QtGui.QTreeWidget.dropEvent(self, eventQDropEvent)

class QCustomQWidget (QtGui.QWidget):
    def __init__ (self, parent = None):
        super(QCustomQWidget, self).__init__(parent)
        self.my1QCustomTreeWidget = QCustomTreeWidget(self)
        self.my2QCustomTreeWidget = QCustomTreeWidget(self)
        self.my1QCustomTreeWidget.itemMoveOutActivated.connect(self.itemMoveOutActivatedCallBack1)
        self.my2QCustomTreeWidget.itemMoveOutActivated.connect(self.itemMoveOutActivatedCallBack2)
        self.my1QCustomTreeWidget.itemNewMoveActivated.connect(self.itemNewMoveActivatedCallBack1)
        self.my2QCustomTreeWidget.itemNewMoveActivated.connect(self.itemNewMoveActivatedCallBack2)
        listsExampleQTreeWidgetItem = [QtGui.QTreeWidgetItem([name]) for name in ['Part A', 'Part B', 'Part C']]
        self.my1QCustomTreeWidget.addTopLevelItems(listsExampleQTreeWidgetItem)
        self.allQHBoxLayout = QtGui.QHBoxLayout()
        self.allQHBoxLayout.addWidget(self.my1QCustomTreeWidget)
        self.allQHBoxLayout.addWidget(self.my2QCustomTreeWidget)
        self.setLayout(self.allQHBoxLayout)

    @QtCore.pyqtSlot(QtGui.QTreeWidgetItem)
    def itemMoveOutActivatedCallBack1 (self, goneQTreeWidgetItem):
        print 'QTreeWidget 1 has move QTreeWidgetItem to Another QTreeWidget'

    @QtCore.pyqtSlot(QtGui.QTreeWidgetItem)
    def itemMoveOutActivatedCallBack2 (self, goneQTreeWidgetItem):
        print 'QTreeWidget 2 has move QTreeWidgetItem to Another QTreeWidget'

    @QtCore.pyqtSlot(QtGui.QTreeWidgetItem)
    def itemNewMoveActivatedCallBack1 (self, newQTreeWidgetItem):
        print 'Another QTreeWidget has move QTreeWidgetItem in QTreeWidget 1'

    @QtCore.pyqtSlot(QtGui.QTreeWidgetItem)
    def itemNewMoveActivatedCallBack2 (self, newQTreeWidgetItem):
        print 'Another QTreeWidget has move QTreeWidgetItem in QTreeWidget 2'

app = QtGui.QApplication(sys.argv)
myQCustomQWidget = QCustomQWidget()
myQCustomQWidget.show()
sys.exit(app.exec_())

希望是有帮助的，
