title: widgets placement in tabs
body: <p>So I have this code:</p>
  
  <pre><code>from PyQt5.QtWidgets import QMainWindow, QApplication, QPushButton, QWidget, QAction, QTabWidget, QVBoxLayout, QHBoxLayout, QComboBox, QLabel
  from PyQt5.QtGui import QIcon
  from PyQt5.QtCore import pyqtSlot
  from lang import getLang
  import sys, os, configparser
  
  config = configparser.ConfigParser()
  config.read("Settings.ini")
  
  # Config get setting and change setting
  #print(config.get("Main", "language"))
  #config.set("Main", "language", "danish")
  #with open("Settings.ini", "w") as cfg_file:
      #config.write(cfg_file)
  
  class App(QMainWindow):
      def __init__(self):
          super().__init__()
  
          # Window Settings
          self.x, self.y, self.w, self.h = 0, 0, 300, 200
  
          self.setGeometry(self.x, self.y, self.w, self.h)
  
          self.window = MainWindow(self)
          self.setCentralWidget(self.window)
          self.setWindowTitle("Window title") # Window Title
          self.show()
  
  class MainWindow(QWidget):        
      def __init__(self, parent):   
          super(QWidget, self).__init__(parent)
          layout = QVBoxLayout(self)
  
          # Run this after settings
          self.lang = getLang(config.get("Main", "language"))
  
          # Initialize tabs
          tab_holder = QTabWidget()   # Create tab holder
          tab_1 = QWidget()           # Tab one
          tab_2 = QWidget()           # Tab two
  
          # Add tabs
          tab_holder.addTab(tab_1, self.lang["tab_1_title"]) # Add "tab1" to the tabs holder "tabs"
          tab_holder.addTab(tab_2, self.lang["tab_2_title"]) # Add "tab2" to the tabs holder "tabs" 
  
          # Create first tab
          tab_1.layout = QVBoxLayout(self)
          tab_2.layout = QVBoxLayout(self)
  
          # Buttons
          button_start = QPushButton(self.lang["btn_start"])
          button_stop = QPushButton(self.lang["btn_stop"])
          button_test = QPushButton(self.lang["btn_test"])
  
          # Button Extra
          button_start.setToolTip("This is a tooltip for the button!")    # Message to show when mouse hover
          button_start.clicked.connect(self.on_click)
  
          button_stop.clicked.connect(self.on_click)
  
          button_test.clicked.connect(self.on_click)
          #button_start.setEnabled(False)
  
          # comboBox
          label_language = QLabel("Language")
          combo_language = QComboBox(self)
          combo_language.addItem(self.lang["language_danish"])
          combo_language.addItem(self.lang["language_english"])
  
          # Move widgets
          combo_language.move(50, 150)
          label_language.move(50, 50)
  
          # Tab Binding
          self.AddToTab(tab_1, button_start)
          self.AddToTab(tab_1, button_stop)
          self.AddToTab(tab_2, label_language)
          self.AddToTab(tab_2, combo_language)
  
          # Add tabs to widget        
          tab_1.setLayout(tab_1.layout)
          tab_2.setLayout(tab_2.layout)
          layout.addWidget(tab_holder)
          self.setLayout(layout)
  
      @pyqtSlot()
      def on_click(self):
          button = self.sender().text()
          if button == self.lang["btn_start"]:
              print("Dank")
          elif button == self.lang["btn_stop"]:
              print("Not dank")
  
      def AddToTab(self, tab, obj):
          tab.layout.addWidget(obj)
  
  if __name__ == '__main__':
      app = QApplication(sys.argv)
      ex = App()
      sys.exit(app.exec_())
  </code></pre>
  
  <p>Currently it creates a window that contains 2 buttons on tab one. A "Start" and "Stop" button with no actual function yet other than printing text.
  On tab 2 I have a label saying "Language:" and a dropdown menu that contains "Danish" and "English". </p>
  
  <p>The problem I have with this, is that it's placement is really really weird and annoying as shown here: <a href="https://i.stack.imgur.com/8X4D5.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/8X4D5.png" alt="Tab One"></a> <a href="https://i.stack.imgur.com/Gu4uz.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Gu4uz.png" alt="Tab 2"></a></p>
  
  <p>I'm not sure how to change the placement as I can't just use <code>.move</code> on the text label, buttons and dropdown menu since they are placed in tabs. </p>
  
  <p>For example, on tab two I would like the label "Language:" to be right to the left of the dropdown menu.</p>
