Object not connected when change in combobox - python

Given a MainWindow with a menu (currently not used) and a table with editable data, there are two problems:
when I change the year or the month I get
table.itemChanged.disconnect(MainCalendar.cellChange)
TypeError: 'function' object is not connected
if I edit a cell of the initial table I get
File "/root/PycharmProjects/mre/cal_main.py", line 78, in cellChange
row = item.row()
AttributeError: 'str' object has no attribute 'row'
P.S. the scripts used in stand alone (not inserted in the MainWindow) work correctly

Many small tables include in a bigger table

I have to create one or more displayboards that will contain smaller tables as you can see from the photos.
Image with 10 names - unusable:
Image with 6 names - 5 are missing:
The problem is that I can't get either a display board extended in length with a scrollbar or two or more displayboards (it depends on how many names are to be entered). I have tried various systems but in the case of "long displayboard" even varying the values ​in window.setGeometry (QtCore.QRect (0, 0, 980, 620)) I can't get the scrollbar, in the case of more displayboards I just can't manage get nothing.
This is the starting piece of code that I used to get the code to work

You cannot and should not modify the GUI directly from another thread, in your case QTableWidget and QTableWidgetItem are part of the GUI so the code: self.tableWidget.setItem(2, 2, QTableWidgetItem(cnt)) is incorrect. What should be done is to send the information to the main thread through elements that are thread-safe such as signals, QEvents, etc.
On the other hand PyQt recommends not modifying the class it generates but creating a widget and using the generated class as an interface(1).
Considering the above the solution is:

(1) Using the Generated Code

Is there a way to change a label of one window from another window?

I've got some code that checks which checkboxes a user clicks. Those are then put into an array (aylm). Once the user clicks the book button, a small confirmation window pops up which says are you sure you want to book these rooms. In this confirmation window, I would like the label to say are you sure you want to book (aylm)? so that all the rooms and times selected can be seen by the user. I am not sure how to go about this since I'm using one main window which connects all the smaller windows together, which you can see below in the code.

for i in range(self.tableWidget.rowCount()):
for j in range(self.tableWidget.columnCount()):
item = self.tableWidget.item(i, j)
if item.checkState() == QtCore.Qt.Checked:
items.append(item)
for it in items:
r = it.row()
c = it.column()
v, h = self.tableWidget.horizontalHeaderItem(c).text(), self.tableWidget.verticalHeaderItem(r).text()
self._checked_items.append([h, v])
aylm = (self.checked_items())

Can't fill some cells of tablewidget. PyQt5

I'm programming a simple csv handler that will just look at two columns using python 3.7.2 and pyqt5. It will have a desired number of rows and all of them needs to be filled for my program to work. But when I run my loops only 11 out of 20 cells get filled. When I decrease the row count to 10 this ratio is 6/10 and for 6 this is 4/6. I can't find why this occurs.
Here is the loop that sets the headers firstly.
x = 0
while x<total_rows:
item = QtWidgets.QTableWidgetItem()
self.tableWidget.setVerticalHeaderItem(x, item)
x+=1
This is the loop that fills the first column with zeros.
x = 0
while x<total_rows:
print(x)
self.tableWidget.setItem(0,x, QtWidgets.QTableWidgetItem("0"))
x+=1
And this is the loop that fills the second column with zeros.
x = 0
while x<total_rows:
print(x)
self.tableWidget.setItem(1,x, QtWidgets.QTableWidgetItem("0"))
x+=1
For other details that you may need when you are solving my problems here is the whole code. (I have no file sharing platforms available right now. Please accept my apologies for sharing the whole code in text.)

I put the print statements if my loops were just wrong. I checked and all loops run 20 times (As the x values reach 19 everytime).
Edit: It seems like double-digits are the problem.But this syntax is surely true according to the documentation.
self.tableWidget.setItem(1,10, QtWidgets.QTableWidgetItem("0"))

You changed rows with columns
# ...
x = 0
while x < total_rows:
# --- self.tableWidget.setItem(0, x, QtWidgets.QTableWidgetItem("0"))
self.tableWidget.setItem(x, 0, QtWidgets.QTableWidgetItem("0")) # +++

And here is my Dialog window which contains a combobox:
class Ui_Dialog(object):
def setupUi(self, Dialog):
Dialog.setObjectName("Dialog")
Dialog.resize(281, 176)
self.comboBox = QtWidgets.QComboBox(Dialog)
self.comboBox.setGeometry(QtCore.QRect(90, 10, 71, 22))
self.comboBox.setObjectName("comboBox")
self.comboBox.addItem("")
self.comboBox_2 = QtWidgets.QComboBox(Dialog)
self.comboBox_2.setGeometry(QtCore.QRect(10, 10, 71, 22))
self.comboBox_2.setObjectName("comboBox_2")
self.comboBox_2.addItem("")
self.dateTimeEdit = QtWidgets.QDateTimeEdit(Dialog)
self.dateTimeEdit.setGeometry(QtCore.QRect(10, 60, 194, 22))
self.dateTimeEdit.setObjectName("dateTimeEdit")
self.label_2 = QtWidgets.QLabel(Dialog)
self.label_2.setGeometry(QtCore.QRect(10, 40, 91, 16))
self.label_2.setObjectName("label_2")
self.lineEdit = QtWidgets.QLineEdit(Dialog)
self.lineEdit.setGeometry(QtCore.QRect(150, 110, 113, 20))
self.lineEdit.setObjectName("lineEdit")
self.label_3 = QtWidgets.QLabel(Dialog)
self.label_3.setGeometry(QtCore.QRect(150, 90, 121, 16))
self.label_3.setObjectName("label_3")
self.lineEdit_2 = QtWidgets.QLineEdit(Dialog)
self.lineEdit_2.setGeometry(QtCore.QRect(10, 110, 113, 20))
self.lineEdit_2.setObjectName("lineEdit_2")
self.label_4 = QtWidgets.QLabel(Dialog)
self.label_4.setGeometry(QtCore.QRect(10, 90, 111, 16))
self.label_4.setObjectName("label_4")
self.pushButton = QtWidgets.QPushButton(Dialog)
self.pushButton.setGeometry(QtCore.QRect(150, 140, 111, 23))
self.pushButton.setObjectName("pushButton")
self.pushButton_2 = QtWidgets.QPushButton(Dialog)
self.pushButton_2.setGeometry(QtCore.QRect(10, 140, 111, 23))
self.pushButton_2.setObjectName("pushButton_2")
self.retranslateUi(Dialog)
QtCore.QMetaObject.connectSlotsByName(Dialog)
So, how do I fill the comboBox_2 exactly, with items from Table Widget?
I am thinking about some kind of cycle, but don't know how to realize it.
I already created classes for the Dialog window and Table Widget class.
class Dialog(QtWidgets.QDialog, Ui_Dialog):
def __init__(self, parent=None):
QtWidgets.QDialog.__init__(self, parent)
self.setupUi(self)
# cancel
self.pushButton_2.clicked.connect(self.reject)
# accept
self.pushButton.clicked.connect(self.accept)
self.dateTimeEdit.setDisplayFormat("d/M/yy hh:mm")
class Masters(QtWidgets.QDialog,Ui_Form):
def __init__(self, parent=None):
QtWidgets.QDialog.__init__(self, parent)
self.setupUi(self)

self.mapping.append((r, c))
self.layoutChanged.emit()
class MainWindow(QtWidgets.QMainWindow, Ui_MainWindow):
def __init__(self, parent=None):
QtWidgets.QMainWindow.__init__(self, parent)
self.setupUi(self)
self.addclient.clicked.connect(self.onAddClient)

You can set the model on the combo-box to the model from the table-widget, and then assign a specific column for the combo-box to use. This will automatically update the combo-box to show whatever items are in the first column of the table-widget whenever it changes. A sort-filter can be used to remove any empty items.
To get this to work, your code will need to look something like this:
class Dialog(QtWidgets.QDialog, Ui_Dialog):
def __init__(self, parent=None):
QtWidgets.QDialog.__init__(self, parent)
...
# set the model
model = QtCore.QSortFilterProxyModel(self)
model.setSourceModel(parent.tableWidget.model())
model.setFilterRegExp('.*\S.*')
model.setFilterKeyColumn(1)
model.setDynamicSortFilter(True)
self.comboBox_2.setModel(model)
self.comboBox_2.setModelColumn(1)
model.sort(1, QtCore.Qt.AscendingOrder)

A robust way to pass data to a QComboBox is to use a model, for this QComboBox has the method setModel(), but an inconvenience for this case is that you can only get the data from a column of QTableWidget, a way to solve that inconvenience is use a proxy to convert the model as a table to a list:
class Table2ListProxyModel(QAbstractProxyModel):
def __init__(self, parent=None):
QAbstractProxyModel.__init__(self, parent)
self.mapping = []
def setSourceModel(self, sourceModel):
sourceModel.dataChanged.connect(lambda: self.fixModel())
QAbstractProxyModel.setSourceModel(self, sourceModel)
self.fixModel()
def mapFromSource(self, sourceIndex):
if sourceIndex.isValid():
key = self.mapping.index((sourceIndex.row(), sourceIndex.column()))
return self.index(key, 0)
return QModelIndex()
def mapToSource(self, proxyIndex):
if proxyIndex.isValid():
r, c = self.mapping[proxyIndex.row()]
return self.sourceModel().index(r, c)
return QModelIndex()
def rowCount(self, parent=QModelIndex()):
return len(self.mapping)
def columnCount(self, parent=QModelIndex()):
return 1
def index(self, row, column, parent=QModelIndex()):
return self.createIndex(row, column)
def parent(self, child):
return QModelIndex()
def fixModel(self):
self.layoutAboutToBeChanged.emit()
self.mapping = []
for c in range(self.sourceModel().columnCount()):
for r in range(self.sourceModel().rowCount()):
ix = self.sourceModel().index(r, c)
data = self.sourceModel().data(ix)
if data is not None and data != "":
self.mapping.append((r, c))
self.layoutChanged.emit()
