Hello guys.
I am having trouble with QTabWidget:
I can't add multiple widgets with addTab nor insertTab.
even when I try something like:
python Syntax (Toggle Plain Text) 
  1. self.widget1 = QListWidget()
  2. self.widget2 = QPushButton("Foo")
  3. self.widget3 = QLabel("Bar")
  4. self.tabs = QTabWidget()
  5. layout = QVBoxLayout()
  6. layout.addWidget(self.widget1)
  7. layout.addWidget(self.widget2)
  8. layout.addWidget(self.widget3)
  9. self.tabs.addTab(layout, "Foobar")

It will raise an error that the first argument (layout) is wrong. :/
Please, any help?

There is not enough code here or enough of the error message to help you. If you are not using a class, the "self." will yield errors. This is an example using QVBoxLayout that hopefully will help.

Yes I am using classes, here is some more information:
Here is a snippet of the code that I am having trouble with:
Python Syntax (Toggle Plain Text) 
  1. import sys
  2. import os
  3. from PyQt4.QtCore import *
  4. from PyQt4.QtGui import *
  5.  
  6. class PyQtFrontend(QDialog):
  7.  
  8.     def __init__(self, rp,parent=None):
  9.         super(PyQtFrontend, self).__init__(parent)
  10.  
  11.         """Initialize our widgets."""
  12.  
  13.  
  14.         self.tabs = QTabWidget()
  15.         self.rpNameLabel = QLabel("Name:")
  16.         self.rpName = QLineEdit("default")
  17.         self.rpName.selectAll()
  18.  
  19.         self.createPointButton = QPushButton("Create")
  20.  
  21.  
  22.         self.layout = QVBoxLayout()
  23.         self.layout.addWidget(self.rpNameLabel)
  24.         self.layout.addWidget(self.rpName)
  25.         self.layout.addWidget(self.createPointButton)
  26.         self.tabs.addTab(self.layout, "Create Tab")

And here's the exception that gets thrown:
Python Syntax (Toggle Plain Text) 
  1.     self.tabs.addTab(self.layout, "Create Tab")
  2. TypeError: argument 1 of QTabWidget.addTab() has an invalid type.

I'm still using qt3, but it should be somewhere in the vicinity of this
Python Syntax (Toggle Plain Text) 
  1.         self.tab_1 = QWidget()
  2.         self.tab_1.setObjectName("Create Tab")
  3.         self.tabs.addTab(self.tab_1, "")
  4.         self.layout.addWidget(self.tabs)

That works for one widget, but what I am trying to achieve is to add multiple widgets to the same tab.

I will only give you a hint since the answer is obvious. The variable is named self.tab_1.
