QTreeView：获取仅高亮显示的项目列表（多选）

Question

我想获得多选的文件夹路径。我只想得到点击时突出显示的那些。理想情况下，一个列表将交互更新。我的意思是，如果一个文件夹被取消选择，它会自动从列表中删除。

下面是QTreeView的一个例子...请问您能提供支持吗？

谢谢

from PyQt4 import QtCore, QtGui 

class Ui_Dialog(object): 
    def setupUi(self, Dialog): 
     Dialog.resize(1150, 905) 
     self.gridLayout_2 = QtGui.QGridLayout(Dialog) 
     self.groupBox  = QtGui.QGroupBox(Dialog) 
     self.gridLayout = QtGui.QGridLayout(self.groupBox) 
     self.treeView  = QtGui.QTreeView(self.groupBox) 
     self.gridLayout.addWidget(self.treeView, 0, 0, 1, 1) 
     self.gridLayout_2.addWidget(self.groupBox, 0, 0, 1, 2) 
     self.fileSystemModel = QtGui.QFileSystemModel(self.treeView) 
     self.fileSystemModel.setFilter(QtCore.QDir.AllDirs | QtCore.QDir.NoDotAndDotDot | QtCore.QDir.AllEntries) 
     self.fileSystemModel.setReadOnly(True) 
     self.root = self.fileSystemModel.setRootPath('/home/') 
     self.treeView.setModel(self.fileSystemModel) 
     self.treeView.setRootIndex(self.root) 
     self.treeView.setSelectionMode(QtGui.QAbstractItemView.ContiguousSelection) 

if __name__ == "__main__": 
    import sys 
    app = QtGui.QApplication(sys.argv) 
    Dialog = QtGui.QDialog() 
    ui = Ui_Dialog() 
    ui.setupUi(Dialog) 
    Dialog.show() 
    sys.exit(app.exec_())

您可以使用QItemSelectionModel的selectedIndexes()方法。

from PyQt4 import QtCore, QtGui 

class Ui_Dialog(object): 
    def setupUi(self, Dialog): 
     Dialog.resize(1150, 905) 
     self.gridLayout_2 = QtGui.QGridLayout(Dialog) 
     self.groupBox  = QtGui.QGroupBox(Dialog) 
     self.gridLayout = QtGui.QGridLayout(self.groupBox) 
     self.treeView  = QtGui.QTreeView(self.groupBox) 
     self.gridLayout.addWidget(self.treeView, 0, 0, 1, 1) 
     self.gridLayout_2.addWidget(self.groupBox, 0, 0, 1, 2) 
     self.fileSystemModel = QtGui.QFileSystemModel(self.treeView) 
     self.fileSystemModel.setFilter(QtCore.QDir.AllDirs | 
      QtCore.QDir.NoDotAndDotDot | QtCore.QDir.AllEntries) 
     self.fileSystemModel.setReadOnly(True) 
     self.root = self.fileSystemModel.setRootPath('/home/') 
     self.treeView.setModel(self.fileSystemModel) 
     self.treeView.setRootIndex(self.root) 
     self.treeView.setSelectionMode(QtGui.QAbstractItemView.ContiguousSelection) 
     self.treeView.selectionModel().selectionChanged.connect(self.getItems) 


    def getItems(self): 
     selected = self.treeView.selectionModel().selectedIndexes() 
     for index in selected: 
      if index.column() == 0: 
       print self.fileSystemModel.data(index, 
        self.fileSystemModel.FileNameRole).toString() 

if __name__ == "__main__": 
    import sys 
    app = QtGui.QApplication(sys.argv) 
    Dialog = QtGui.QDialog() 
    ui = Ui_Dialog() 
    ui.setupUi(Dialog) 
    Dialog.show() 
    sys.exit(app.exec_())
