【问题描述】：
我正在制作一个我想要一个 FileTree 的程序（我已经有了这个，但没有 QfileSystemMoodle，这使得以后做事变得更加困难）。在这里，我必须能够在活动文件夹（我还不能选择，所以现在是硬编码的）中输入的文件名（这工作）录制一些声音，然后必须更新文件树。我更喜欢为此使用 QFileSystemModel，因为它使之后的编辑变得更容易。
所以我的问题是：带有 QFileSystemModel 的树视图，活动/选定路径作为记录位置并在记录或其他修改后更新。
这个我试过了，但我不能让它工作，我不需要过滤器：
import os, sys
import sounddevice as sd
from scipy.io.wavfile import write
from PyQt5 import QtCore, QtGui, QtWidgets, uic
from PyQt5.QtWidgets import QTreeWidgetItem, QFileSystemModel
from pathlib import Path
qtcreator_file = "mainwindow.ui" # Enter file here.
Ui_MainWindow, QtBaseClass = uic.loadUiType(qtcreator_file)
class MyWindow(QtWidgets.QMainWindow, QtWidgets.QFileSystemModel, Ui_MainWindow):
def __init__(self):
QtWidgets.QMainWindow.__init__(self, parent=None)
Ui_MainWindow.__init__(self)
QtGui.QFileSystemModel.__init__(self, None)
self.checks = {}
self.FileStruckture
self.setupUi(self)
self.opnemen.clicked.connect(self.capture)
def data(self, index, role=QtCore.Qt.DisplayRole):
if role != QtCore.Qt.CheckStateRole:
return QtGui.QFileSystemModel.data(self, index, role)
else:
if index.column() == 0:
return self.checkState(index)
def flags(self, index):
return QtGui.QFileSystemModel.flags(self, index) | QtCore.Qt.ItemIsUserCheckable
def checkState(self, index):
if index in self.checks:
return self.checks[index]
else:
return QtCore.Qt.Checked
def setData(self, index, value, role):
if (role == QtCore.Qt.CheckStateRole and index.column() == 0):
self.checks[index] = value
self.emit(QtCore.SIGNAL("dataChanged(QModelIndex,QModelIndex)"), index, index)
return True
return QtGui.QFileSystemModel.setData(self, index, value, role)
self.dirTreeView = QtWidgets.QTreeWidget(self.FileStruckture)
self.dirModel = CheckableDirModel()
self.dirTreeView.setModel(self.dirModel)
def capture(self):
fs = 44100 # Sample rate
seconds = 6 # Duration of recording
myrecording = sd.rec(int(seconds * fs), samplerate=fs, channels=2)
sd.wait() # Wait until recording is finished
locatie = "D:/DemoGIPhoofdmap/bedrijf 08"
locatiepath = Path(locatie)
file_name = "/" + (self.filename.text()) + ".wav"
write_path = locatie + file_name
write(write_path, fs, myrecording) # Save as WAV file
if __name__ == "__main__":
app = QtWidgets.QApplication(sys.argv)
window = MyWindow()
window.show()
sys.exit(app.exec_())
这是最有效的，但它不适用于 QFileSystemMoodle，它不会更新，我无法从中获取活动路径：
import os, sys
import sounddevice as sd
from scipy.io.wavfile import write
from PyQt5 import QtCore, QtGui, QtWidgets, uic
from PyQt5.QtWidgets import QTreeWidgetItem
from PyQt5.QtGui import QIcon
from pathlib import Path
qtcreator_file = "mainwindow.ui" # Enter file here.
Ui_MainWindow, QtBaseClass = uic.loadUiType(qtcreator_file)
class MyWindow(QtWidgets.QMainWindow, Ui_MainWindow):
def __init__(self):
QtWidgets.QMainWindow.__init__(self)
Ui_MainWindow.__init__(self)
self.setupUi(self)
self.FileStruckture
self.file_tree("D:/DemoGIPhoofdmap", self.FileStruckture)
self.opnemen.clicked.connect(self.capture)
def file_tree(self, startpath, tree):
startpath = Path(startpath)
for element in os.listdir(startpath):
path_info = startpath / element
parent_itm = QTreeWidgetItem(tree, [os.path.basename(element)])
if os.path.isdir(path_info):
self.file_tree(path_info, parent_itm)
parent_itm.setIcon(0, QIcon('assets/folder.ico'))
else:
parent_itm.setIcon(0, QIcon('assets/file.ico'))
def capture(self):
fs = 44100 # Sample rate
seconds = 6 # Duration of recording
myrecording = sd.rec(int(seconds * fs), samplerate=fs, channels=2)
sd.wait() # Wait until recording is finished
locatie = "D:/DemoGIPhoofdmap/bedrijf 08"
locatiepath = Path(locatie)
file_name = "/" + (self.filename.text()) + ".wav"
write_path = locatie + file_name
write(write_path, fs, myrecording) # Save as WAV file
if __name__ == "__main__":
app = QtWidgets.QApplication(sys.argv)
window = MyWindow()
window.show()
sys.exit(app.exec_())
这是来自 QT Creator 的 XML 代码
