我想从pyqt5中的树视图中获取文件路径和文件名。我可以使用它,但是我想实现搜索,但是可以,但是这样做牺牲了获取文件名和文件路径的能力。 这是我的树:
class Folder_Screeen(QDialog):
def __init__(self, parent = None):
super(Folder_Screeen, self).__init__(parent)
self.path = expanduser(os.path.dirname(os.path.realpath(__file__)))
self.pathRoot = QDir.rootPath()
self.labelFileName = QLabel(self)
self.labelFileName.setText("Search:")
self.labelFileName.resize(100, 30)
self.txtSearch = QLineEdit(self)
self.txtSearch.textChanged.connect(self.on_textChanged)
self.thumbnail = QLabel(self)
self.model = QFileSystemModel()
self.model.setRootPath(QDir.rootPath())
self.model.setFilter(QDir.NoDotAndDotDot | QDir.AllEntries | QDir.Dirs | QDir.Files)
self.proxy_model = QSortFilterProxyModel(recursiveFilteringEnabled = True, filterRole = QFileSystemModel.FileNameRole)
self.proxy_model.setSourceModel(self.model)
self.model.setReadOnly(False)
self.model.setNameFilterDisables(False)
self.indexRoot = self.model.index(self.model.rootPath())

self.treeView.setModel(self.proxy_model)
self.adjust_root_index()

self.treeView.customContextMenuRequested.connect(self.showContextMenu)
@QtCore.pyqtSlot(str)

self.adjust_root_index()

def on_treeView_clicked(self, index):
indexItem = self.model.index(index.row(), 0, index.parent())# print(indexItem)
fileName = self.model.fileName(indexItem)
filePath = self.model.filePath(indexItem)
self.thumbnail.setPixmap(QPixmap(filePath))
self.thumbnail.setAlignment(Qt.AlignRight | Qt.AlignBottom)
print(fileName)
print(filePath)
def dragEnterEvent(self, event):

if m.hasUrls():

return
event.ignore()
def dropEvent(self, event):
if event.source():
QTreeView.dropEvent(self, event)

# TREE VIEW END ====================================
我没有任何输出,只是一个空字符串或主系统驱动器。
如果我在第26行更改此行代码,则solotuons可以工作
self.treeView.setModel(self.proxy_model)
到
self.treeView.setModel(self.model)
但是,如果这样做,我将无法搜索文件。
答案 0 :(得分:1)
如果已将QSortFilterProxyModel设置为模型,则通过其信号发送QTreeView的QModelIndex将属于该模型,因此,如果您想从QFileSystemModel获取信息,显然它们将失败,解决方案是获取相应的使用mapToSource()方法的QModelIndex:
@QtCore.pyqtSlot(QtCore.QModelIndex)
def on_treeView_clicked(self, index):
source_index = self.proxy_model.mapToSource(index)
indexItem = self.model.index(source_index.row(), 0, source_index.parent())
fileName = self.model.fileName(indexItem)
filePath = self.model.filePath(indexItem)
self.thumbnail.setPixmap(QPixmap(filePath))
self.thumbnail.setAlignment(Qt.AlignRight | Qt.AlignBottom)
print(fileName)
print(filePath)
