python，PyQt4 -使用Enter键获取QTreeView中的文件夹路径

from PyQt4.QtGui import QApplication, QTreeView, QFileSystemModel
from PyQt4.QtCore import Qt, QModelIndex

app = QApplication([])
treeView = QTreeView()
fileSystemModel = QFileSystemModel()

treeView.setModel(fileSystemModel)
treeView.setRootIndex(fileSystemModel.setRootPath('/'))

def handleEnterPressed():
    currentIndex = treeView.currentIndex()
    filePath = fileSystemModel.filePath(currentIndex)
    print(filePath)  # 在控制台输出文件夹路径

treeView.keyPressEvent = lambda event: handleEnterPressed() if event.key() == Qt.Key_Return else None

treeView.show()
app.exec_()
