Refresh/Re-open Qdialog with QTableWidget inside

I have a program that is "divided" in 6 classes, the first class is the Main Window where I can choose where I'd like to go (I have 4 choices, a page to visualize all the data, one to modify and the other 2 to visualize data with filters), each of theese pages is a QDialog that contains a QTableWidget, this table is connected to a SQL Server database and shows data from a specific table (to be honest it shows data from 2 tables).
My problem is:
In the 2 class ("modificaviaggi") I connected some signals to some action, first of all I connected the itemChanged signal to a method that stores the items written by the user and saves them in the SQL DB, the signal signal I used is the clicked signal, I connected this signal to a method that verifies if the cell clicked it's the 8 or 9, in case it's 8 or 9 it shows another QDialog (class "articoli") where the user can insert some data regarding weight of every product, this weight data are stored in a second table in the SQL Server DB, I use this table to get the weight for every product when I show my table.
So I get all the data from the table SQL "Viaggi" and then I verify if there are some values in the SQL table "Pesi" for each row of the table "Viaggi" using the row ID.
Now the complicated part is that when the user click the columns 8 or 9 it shows another Qdialog, I show this Qdialog everytime the user clicks the columns 8 or 9, then the user can write data on the table and those data will be stored in the table "Pesi", thanks to the variable "lastID" declared on the "modificaviggi" class I know for which row the user clicked the columns 8 or 9, thanks to that I store the values in the SQL table and for each value I have their row ID, now that the situation is more clear the real question is: How can "Re-load" the QTableWidget "tabella_registrazioni" inside the class "modificaviaggi" everytime the user clicks the QPushButton "get_back_button"? Because in the class "articoli" the user modifies/adds values for each row in the QTableWidget "tabella_registrazioni" but I can't reload the data inside here's my code :

One solution could be to set up signals that would update the table as the user makes changes so there would be no need to refresh at all.
For example:
Set up a signal in your dialog class that will be emitted whenever the user changes the data. Then in the original dialog with the table you want to update, connect to that signal after initializing the dialog.
here is a minimal example:
import sys
from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *
def populate_table(table):
for i in range(10):
table.insertRow(table.rowCount())
for j in range(2):
item = QTableWidgetItem(type=0)
item.setText(f"({i}, {j})")
table.setItem(i,j,item)
class Dialog2(QDialog):
tableInfoChanged = pyqtSignal([int, int, str])
def __init__(self,parent=None):
super().__init__(parent=parent)
self.layout = QVBoxLayout()
self.setLayout(self.layout)
self.table = QTableWidget()
self.table.setColumnCount(2)
self.layout.addWidget(self.table)
populate_table(self.table)
self.table.cellChanged.connect(self.emitChangedInfo)
def emitChangedInfo(self, row, col):
text = self.table.item(row, col).text()
self.tableInfoChanged.emit(row, col, text)
class Dialog1(QDialog):
def __init__(self,parent=None):
super().__init__(parent=parent)
self.layout = QVBoxLayout()
self.setLayout(self.layout)
self.table = QTableWidget()
self.table.setColumnCount(2)
self.button = QPushButton("Push to open dialog2")
self.layout.addWidget(self.table)
self.layout.addWidget(self.button)
populate_table(self.table)
self.button.clicked.connect(self.openDialog2)
def updateTable(self, row, col, text):
self.table.item(row,col).setText(text)
def openDialog2(self):
self.dialog2 = Dialog2()
self.dialog2.tableInfoChanged.connect(self.updateTable)
self.dialog2.exec()
app = QApplication(sys.argv)
window = Dialog1()
window.show()
sys.exit(app.exec_())
I have tested this code and should function as is.

How to read a SQL Stored Procedure into a pandas dataframe?

Thanks all for your suggestions. Adding self. before calling my functions fixed that issue. I'm now running into a different issue where the stored procedure I am using isn't getting properly read into the pandas dataframe. I don't get any errors, the tkinter window pops up like it should, but when the PDF gets generated, there is no data in the rows, just the column names and other formatting I've written in.
I added print(df) to the code to check if it was an issue with the data getting read from the dataframe to the PDF, but print(df) just returns Empty DataFrame.

How to place radio button at each row in qtablewidget and allow only one row to select from group of rows?

Below is my table :
In the above table, i have placed the Radiobutton at each row.
In the table, column 'field' has same values in the rows i.e startdate is present in two rows and validity is also repeating in rows.
What i want is to only select only one row consisting validity from the repeating values using radio button. if user selects another value,it must deselect previously selected value.

PyQt populate QTableWidget from excel

im trying to populate QTableWidget with some data from excel file, i want to add row to my QTable only if ID is on the listID, and i get no data in QTable cells
https://drive.google.com/file/d/0B_PFK3V2Ij4tSko4emplYmNuN1E/view?usp=sharing here an excel file, it don't contain any formatin or formula, just empty rows and columns, because file is generated automaticaly
here is my code
wb = openpyxl.load_workbook(os.path.join(os.getcwd(), file), read_only=True)
ws = wb.active
headers = []
for item in ws[4]:
headers.append(item.value)
headers.pop(0)
listID = []
for index in range(self.listWidgetID.count()):
listID.append(self.listWidgetID.item(index).text())
data = ws.iter_rows(row_offset=5, column_offset=1)
row_increment = 0
self.tableWidgetDATA.setRowCount(1)
self.tableWidgetDATA.setColumnCount(len(headers))
self.tableWidgetDATA.setHorizontalHeaderLabels(headers)
for x, rows in enumerate(data):
if str(rows[0].value) in listID:
for y, cell in enumerate(rows):
item = QTableWidgetItem(str(cell.value))
self.tableWidgetDATA.setItem(x, y, item)
row_increment = row_increment + 1
self.tableWidgetDATA.setRowCount(row_increment)

To add elements to the QTableWidget, the position must be setRowCount(), in your case you update after adding, so it will not be saved, Another error is that you do not verify if the data is valid.
class Widget(QWidget):
def __init__(self, parent=None):
QWidget.__init__(self, parent)
self.tableWidgetDATA = QTableWidget(self)
self.listWidgetID = QListWidget(self)
self.setLayout(QVBoxLayout())

self.listWidgetID.addItems(["113894", "113906", "113895"])
file = "Livro2.xlsx"
wb = openpyxl.load_workbook(os.path.join(os.getcwd(), file), read_only=True)
ws = wb.active

WX.EVT_LISTBOX_DCLICK click for get diffrent information from database

I have a problem when I do click on the listbox, In my program, I did click on the listbox will appear a video and explain about the video. I made a sample in the database are "name_link" which will appear in the listbox. expl1, expl2, expl3. Of each name_link have different information. However, that happens every time I click on one of these name_link, video that appears only Video3 and system never show the explain about video. When I click name_link video1 video2 emerging or always Video3. I am so stuck in this section.
this section during click :
tb4 = wx.StaticText(self, -1, label='explain', pos=(20, 145))
wx.TextCtrl(self, -1, pos=(80, 145), size=(220, 120))
self.opt = wx.ListBox(pan1, -1, pos=(10, 210), size=(480, 250), style= wx.TE_MULTILINE | wx.BORDER_SUNKEN)
def playFile(self, event):
self.player.Play()
def OnEnter(self, event):
self.opt.SetLabel(self.PatMatch())
def PatMatch(self):
con = sqlite3.connect('test.db')
with con:
cur = con.cursor()
for row in cur.execute("Select * From Video"):
klmt = self.inpt.GetValue()
if row[1] in klmt.lower():
self.opt.Append(row[2])
self.player.Load(row[4])
return self.Bind(wx.EVT_LISTBOX_DCLICK, self.playFile, self.op)
The data base like this :
id word name_link explain link
--- ------ ----------- --------- --------
1 python Video1 test C:\Users\Ihsan\Downloads\Video1.MP4
2 python Video2 test1 C:\Users\Ihsan\Downloads\Video2.MP4
3 python Video3 test2 C:\Users\Ihsan\Downloads\Video3.MP4

There are several issues:
You want bind wx.EVT_LISTBOX_DCLICK only once. When the event is fired, you want to read out which item (GetSelection) was selected when double-clicking. Use GetSelections for multiple selections.
Bad indentation: In the inner loop (self.player…) and with the return self.Bind… which should be in the innermost loop. As it is written now it will bind once to the last element. As written in point 1 this is not the way how it is done anyhow.
In Bind, self.op should be self.opt
See the wxPython demo on the download page to see how to use ListBox sensibly.

I was try create some code like this.
def playVideo(self, evt, temp):
self.player.Load(evt.GetClientObject())
self.Play(True)
self.pjs.Clear()
self.pjs.AppendText(evt.GetClientObject())
Its work for the video, the video can play. but for the information from column database explain, its not show. i want the information from column explain print in tb4. #nepix32
