Перетаскивание между двумя QTreeViews

Моя цель - сделать перетаскивание между двумя QTreeView. Например: перетащите элемент из локального древовидного представления в удаленное древовидное представление, удаленное древовидное представление примет сигнал и вызовет одну функцию (например: напечатать что-то, чтобы я знал, что это удалось).

Я искал несколько сообщений, они просто делают с одним QTreeView, и я все еще не понимаю, как использовать перетаскивание. Это мой полный код, включая пользовательский интерфейс.

Ваш код очень длинный. Конечно, вы могли бы сделать меньший (минимальный) пример, который показывает только интересные части вашей проблемы?   -  person Trilarion    schedule 02.09.2014

Если вы обмениваетесь данными между двумя виджетами, я предлагаю использовать QTreeWidget больше, чем QTreeView, потому что данные в QTreeWidget могут редактировать динамические данные, строку и значение. При перетаскивании между 2 QTreeWidget мы можем эквивалентно им «копировать и удалить».

Легко реализовать между 2 QTreeWidget, вы просто обрабатываете, когда перетаскиваете событие ввода в QTreeWidget и копируете в новый QTreeWidget. (Если ваше внутреннее перемещение, я сам удалю старые данные) Затем создайте свой собственный сигнал для их обработки, если есть перемещение данных между QTreeWidget. Наконец, интегрируйте его в свой класс или виджет.

Пример (это не ваш код, но вы можете реализовать его самостоятельно), вот так;

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_())

Надежда помогает,

Спасибо за ваше предложение и образец. я считаю QTreeView более сложным в использовании. - person soneedu; 29.08.2014
