It's been a while I'm searching all over the internet for that, but still couldn't get the answer... basically I have a QVBoxLayout which contains several frames - and each frame contains a button which function is to delete its parent frame. The main code was created using QT Designer and pyuic4. I wrote the two additional functions, one works perfectly ("createFrame") but I'm struggling with the "deleteFrame" one. the label inside the frame shows the index of that frame in the vert_layout "array". the problem I noted on my code is that, using it that way, I can only delete the last frame added. So, can someone help me with this issue?
please see my code below:

All you are currently doing is deleting the self.frame widget each time.
So only the last created one gets deleted. And not the one you actually click on.
Modified your code for what you need. Hope it helps you understand.

I need a signal or event from the QtableView to capture the row number user selects
Here I tried an event filter to get the Mouse Button Press event, but nothing got filtered out, yet the same filter works for Context Menu event, Is there any related method to capture signal from table view? (like cellClicked.connect in QTableWidget)

By this I tried to make a minimal reproducible example of what I now have.
Using QSortFilterProxyModel() to find text and a custom SortFilterProxyModel to show all the selected checkboxes.
It looks like both proxy's conflicting eachother and giving the wrong row number back. (There is also an option for adding value with a dialog and also this goes to the wrong row with the custom proxy enabled, but works without the custom proxy).

If I create my UI in QT Designer (and import UI to the script), how can I hide and show tabs in my script?
class Tool(QMainWindow, uiTool.Ui_Tool):
def __init__(self):
super(Tool, self).__init__()
# SETUP UI
self.setupUi(self)
# self.tabWidget.removeTab() ???
There is no way to hide/show the tabs in a tab-widget, so you will need to remove and replace them instead.
Below is a demo script that shows how to do this. I have not attempted to keep track of the original indexes in this example - it just shows the basic usage of the methods involved:

from PyQt5 import QtCore, QtWidgets
class Ui_Form(object):
def setupUi(self, Form):
Form.setObjectName("Form")
Form.resize(354, 268)
self.gridLayout = QtWidgets.QGridLayout(Form)
self.gridLayout.setObjectName("gridLayout")
self.tabWidget = QtWidgets.QTabWidget(Form)
self.tabWidget.setObjectName("tabWidget")
self.tabRed = QtWidgets.QWidget()
self.tabRed.setObjectName("tabRed")
self.tabWidget.addTab(self.tabRed, "")
self.tabBlue = QtWidgets.QWidget()
self.tabBlue.setObjectName("tabBlue")
self.tabWidget.addTab(self.tabBlue, "")
self.tabGreen = QtWidgets.QWidget()
self.tabGreen.setObjectName("tabGreen")
self.tabWidget.addTab(self.tabGreen, "")
self.gridLayout.addWidget(self.tabWidget, 0, 0, 1, 2)
self.buttonRemove = QtWidgets.QPushButton(Form)
self.buttonRemove.setObjectName("buttonRemove")
self.gridLayout.addWidget(self.buttonRemove, 1, 0, 1, 1)
self.buttonRestore = QtWidgets.QPushButton(Form)
self.buttonRestore.setObjectName("buttonRestore")
self.gridLayout.addWidget(self.buttonRestore, 1, 1, 1, 1)
self.retranslateUi(Form)
self.tabWidget.setCurrentIndex(2)
QtCore.QMetaObject.connectSlotsByName(Form)
def retranslateUi(self, Form):
_translate = QtCore.QCoreApplication.translate
Form.setWindowTitle(_translate("Form", "Form"))
self.tabWidget.setTabText(self.tabWidget.indexOf(self.tabRed), _translate("Form", "Red"))
self.tabWidget.setTabText(self.tabWidget.indexOf(self.tabBlue), _translate("Form", "Blue"))
self.tabWidget.setTabText(self.tabWidget.indexOf(self.tabGreen), _translate("Form", "Green"))
self.buttonRemove.setText(_translate("Form", "Remove"))
self.buttonRestore.setText(_translate("Form", "Restore"))
class Window(QtWidgets.QWidget, Ui_Form):
def __init__(self):
super(Window, self).__init__()

self.buttonRemove.clicked.connect(self.handleButtonRemove)
self.buttonRestore.clicked.connect(self.handleButtonRestore)

self.tab_pages.append((
self.tabWidget.widget(index),
self.tabWidget.tabText(index),

I have a little problem with a variable update.
I have my variable declared in my first function as such self.TestVar = 0
then if a certain count ==2 self.TestVar = 2
in a second function (in the same class) but called from within another class I want returning self.TestVar. no way.
AttributeError: 'ThndClass' object has no attribute 'TestVar'
I am most certainly not doing the good way, all I want is accessing self.TestVar = 2 from my other class that's it's but I can't find a proper way to do so in Python.
It looks like my issue is that I get my self.TestVar = 2 in a "if" statement which make it live in another scope (or I might be wrong).
import sys
from PIL import Image
from PyQt4 import QtCore, QtGui
class MainWindow(QtGui.QWidget):
def __init__(self):
super(MainWindow, self).__init__()
self.initUI()
def initUI(self):
self.TestVar = 0
self.TheCount = 2
if self.TheCount ==2:
self.TestVar = 2
ThndClass()
def Getit(self):
print("called correctly")
print(self.TestVar)
return self.TestVar
def main():
app = QtGui.QApplication([])
mw = MainWindow()
sys.exit(app.exec_())
class ThndClass(QtGui.QWidget):
def __init__(self):
super(ThndClass, self).__init__()
self.initUI2()
def initUI2(self):
print("Class Called")
print(MainWindow.Getit(self))
if __name__ == '__main__':
main()
If I remove the 2nd Class call :
import sys
from PIL import Image
from PyQt4 import QtCore, QtGui
class MainWindow(QtGui.QWidget):
def __init__(self):
super(MainWindow, self).__init__()
self.initUI()
def initUI(self):
self.TestVar = 0
self.TheCount = 2
if self.TheCount ==2:
self.TestVar = 2
self.Getit()
def Getit(self):
print("called correctly")
print(self.TestVar)
return self.TestVar
def main():
app = QtGui.QApplication([])
mw = MainWindow()
sys.exit(app.exec_())
if __name__ == '__main__':
main()
This works correctly, but I want to be able to call def Getit() from another class and get my result. Or simply get a way to directly access self.TestVar from my other class.
When you call
MainWindow.Getit(self)
in ThndClass.initUI2, you are treating MainWindow and ThndClass interchangeably, when they do not have the same attributes. Here is an actual minimal example:
class Parent():
def __init__(self):
pass
class Child1(Parent):
def __init__(self):
super().__init__()
self.foo = "foo"
def method(self):
print(type(self))
print(self.foo)
class Child2(Parent):
def __init__(self):
super().__init__()
self.bar = "bar"
c1 = Child1()
Child1.method(c1) # pass Child1 instance to Child1 instance method
c2 = Child2()
Child1.method(c2) # pass Child2 instance to Child1 instance method
and full output:
<class '__main__.Child1'> # gets a Child1 instance
foo # first call succeeds
<class '__main__.Child2'> # gets a Child2 instance (which doesn't have 'foo')
Traceback (most recent call last):
File "C:/Python34/so.py", line 25, in <module>
Child1.method(c2)
File "C:/Python34/so.py", line 11, in method
print(self.foo)
AttributeError: 'Child2' object has no attribute 'foo' # second call fails
However, as it is not clear what exactly the code is supposed to be doing, I can't suggest a fix. I don't know why you create but don't assign a ThndClass instance in MainWindow.initUI, for example.
Here is one possible fix; pass a Child1 instance to Child2.__init__, then use it either as an argument to Child2.method:
class Child2(Parent):
def __init__(self, c1): # provide Child1 instance as parameter
super().__init__()
self.bar = "bar"
self.method(c1) # pass instance to Child2.method
def method(self, c1):
c1.method() # call Child1.method with c1 as self parameter
(Note that c1.method() is equivalent to Child1.method(c1).)
or make it an instance attribute:
class Child2(Parent):
def __init__(self, c1): # provide Child1 instance as parameter
super().__init__()
self.bar = "bar"
self.c1 = c1 # make Child1 instance a Child2 instance attribute
self.method() # now no argument needed
def method(self):
self.c1.method() # call Child1.method with c1 as self parameter
(Note that self.c1.method() is equivalent to Child1.method(self.c1).)
In use (either way):
>>> c1 = Child1()
>>> c2 = Child2(c1)
<class '__main__.Child1'> # Child1.method gets a Child1 instance
foo # and is called successfully

All working good now : ) Thanks you very much !
I am working with a QMainWindow and adding a QTableView widget. The table is to be filled with data from a csv file. The csv file first row has the headers, but I cannot find how to write that row into the headers. Even inputting a test header list does not work.
Also I want to reverse sort on the "time" column.
Here is code restricted to mostly the table:
import sys
import csv
from PyQt4 import QtGui
from PyQt4.QtCore import *
from array import *
class UserWindow(QtGui.QMainWindow):
def __init__(self, parent=None):
super(UserWindow, self).__init__()
self.specModel = QtGui.QStandardItemModel(self)
self.specList = self.createSpecTable()

def specData(self):
with open('testFile.csv', 'rb') as csvInput:
for row in csv.reader(csvInput):
if row > 0:
items = [QtGui.QStandardItem(field) for field in row]
self.specModel.appendRow(items)
def createSpecTable(self):
self.specTable = QtGui.QTableView()
# This is a test header - different from what is needed
specHdr = ['Test', 'Date', 'Time', 'Type']
self.specData()
specM = specTableModel(self.specModel, specHdr, self)
self.specTable.setModel(specM)
self.specTable.setShowGrid(False)
vHead = self.specTable.verticalHeader()
vHead.setVisible(False)

hHead.setStretchLastSection(True)
self.specTable.sortByColumn(3, Qt.DescendingOrder)
return self.specTable
def initUI(self):
self.ctr_frame = QtGui.QWidget()

self.refBtn = QtGui.QPushButton("Reference")
self.stpBtn = QtGui.QPushButton("Blah")

class specTableModel(QAbstractTableModel):
def __init__(self, datain, headerdata, parent=None, *args):

return QVariant()
return QVariant(self.arraydata[index.row()][index.column()])
def headerData(self, col, orientation, role):

return self.headerdata[col]
return None
def main():
app = QtGui.QApplication(sys.argv)
app.setStyle(QtGui.QStyleFactory.create("plastique"))
ex = UserWindow()
ex.show()
sys.exit(app.exec_())
if __name__ == '__main__':

and here is a really short csv file:
Run,Date,Time,Comment
data1,03/03/2014,00:04,Reference
data2,03/03/2014,02:00,Reference
data5,03/03/2014,02:08,Sample
data6,03/03/2014,13:57,Sample
Also the rowCount & columnCount definitions do not work.
Worked out answers to what I posted: Wrote a 'getHeader' function simply to read the first line of the csv file and returned the list. Added the following to the createSpecTable function:
specHdr = self.getHeader()
self.specModel.setHorizontalHeaderLabels(specHdr)
self.specModel.sort(2, Qt.DescendingOrder)
The last statement solved the reverse sort problem. The header line from the csv file was removed from the table by adding a last line to the specData function:
self.specModelremoveRow(0).
Finally the rowCount and columnCount were corrected with:
def rowCount(self, parent):
return self.arraydata.rowCount()
def columnCount(self, parent):
return self.arraydata.columnCount()
