Hi,
I am trying to make a simple files app (or, file explorer app) and I am
using the QTableWidget to Display the files and directories. When the user
clicks an directory, I want the program to jump to that directory. I have
used the QTableWidget.cellClicked signal, and it does not currently work.
The signal part:
self.filesTable.connect(print)#self.updateUiCellClick)
Added print instead of self.updateUiCellClick for debugging purposes.
Code (probably you do not need this):
#!/usr/bin/python3
print('i Import Modules')
print(' | Import sys')
import sys
print(' | Import PyQt5.QtCore')
from PyQt5.QtCore import *
print(' | Import PyQt5.QtGui')
from PyQt5.QtGui import *
print(' | Import PyQt5.QtWidgets')
from PyQt5.QtWidgets import * # PyQt5 Support
print(' | Import os')
import os
print(' | Import subprocess.Popen') # For backward-compatibility
from subprocess import Popen, PIPE
print(' | Done')
print('i Define class Form')
class root(QMainWindow):
def __init__(self, parent=None):
'''self.__init__ - Initializes QMainWindow'''
print(' self.__init__ - Initializes QMainWindow')
super(root, self).__init__(parent)
# Create Variables
self.currentPath = '/'
os.chdir(self.currentPath)
self.currentItems = os.listdir()
self.currentItemsLsProcess = Popen(['ls','-l'], stdout=PIPE,
stderr=PIPE)
self.currentItemsLsProcessResult =
self.currentItemsLsProcess.communicate()
if self.currentItemsLsProcessResult[1].decode('utf-8'):
QMessageBox.warning(self,'Files - ls -l Error','ls -l responded
with non-blank stderr.Error is shown

(e-lsstderr)<br><hr><br>If you want to support the team, go to the <a href="

self.currentItemsLs =
self.currentItemsLsProcessResult[0].decode('utf-8').split('\n')[1:-1]
# Create Table Widget
self.filesTable = QTableWidget()
# Init Table Widget
self.filesTable.clear()
self.filesTable.setSizeAdjustPolicy(QAbstractScrollArea.AdjustToContents)
self.filesTable.setRowCount(len(self.currentItems))
self.filesTable.setColumnCount(4)
self.filesTable.setHorizontalHeaderLabels(['Name','TimeStamp','Type','ls
-l'])
# self.filesTable.setReadOnly(1)
# Create & Add Items
self.itemWidgets = [[],[],[],[]]
for i in range(len(self.currentItems)):
self.itemWidgets[0].append(QTableWidgetItem(self.currentItems[i]))
self.filesTable.setItem(i,0,self.itemWidgets[0][-1])
self.itemWidgets[3].append(QTableWidgetItem(self.currentItemsLs[i]))
self.filesTable.setItem(i,3,self.itemWidgets[3][-1])
# Init Widgets
# Align Widgets to root
self.setCentralWidget(self.filesTable)
# Signals-and-Slots
print('i Set self title')
self.setWindowTitle('{}'.format(self.currentPath))
def updateUi(self):
'''self.updateUi - None'''

self.filesTable.setItem(i,3,self.itemWidgets[3][-1])
self.filesTable.resizeColumnsToContents()
self.setWindowTitle('{}'.format(self.currentPath))
def updateUiCellClick(self, row, column):
'''self.updateUiCellClick - None'''
print('self.updateUiCellClick - None')
self.currentpath += self.itemWidgets[0][row].text+'/'
self.updateUi()
print(' | Done')
if __name__ == '__main__':
print('i Execute instance')
app = QApplication(sys.argv)
root = root()
root.show()
app.exec_()
print(' | Done')
Any help would be appreciated,
Ken
