I'm Currently making a TextBased game with pyqt5 and I'm using the designer to make the Windows because it was easier, everything was fine until I tried to find out how to Destroy a single Child window I found some Answers but it didn't Fit my Situation (or I'm just bad at this).
Note: I'm using the Designer to Make the UI
Issue: Couldn't Find an Answer to My Problem Which is Destroying a Child Window (HuntTab) when Hp is lesser than 1

When a widget is set in a ScrollArea the size it uses is that of the widget at that moment, in your case it does not have any size so the widget will have size 0, 0 and although you add child widgets through a QScrollArea layout, it does not will take into account, so for QScrollArea to monitor the size you must enable the widgetResizable property:
self.scroll = QtGui.QScrollArea(widgetResizable=True)
I have three main sections of a main window, where the left side (critical data) should take the entire height of the window, while the data on the right should be split between top and bottom. Data in the lower right is related, but not critical - which is why I'd like it to be un-dockable/closable.
The Qt documentation shows an example of this in C++, but I have no idea how to turn this into Python code, as I have no C++ experience.
The Qt Designer application limits the user to Left/Right/Top/Bottom, and limiting the maximum width of the widget doesn't allow me to occupy the un-used space (i.e. doesn't allow the list widget on the left to take up the full height of the main window)
Long story short, to get a Qdockwidget into the lower right corner, you have to put another dock widget above it (it's still limited to Right/Left/Top/Bottom DockWidgetArea). After looking at the answer from eyllanesc below, I'll post two solutions. First, a simplified version of his code and then a modified version of the code I originally posted.
Eyllanesc's translation from the C++ example from I mentioned above:
from PyQt4 import QtCore, QtGui
class MainWindow(QtGui.QMainWindow):
def __init__(self, parent=None):
QtGui.QMainWindow.__init__(self, parent)
self.resize(600, 600)
self.centralWidget = QtGui.QTextEdit()
self.setCentralWidget(self.centralWidget)
# Upper table widget
dock = QtGui.QDockWidget("Upper", self.centralWidget)
dock.setAllowedAreas(QtCore.Qt.RightDockWidgetArea)
self.tableWidget = QtGui.QTableWidget(dock)
self.tableWidget.setObjectName("tableWidget")
self.tableWidget.setColumnCount(6)
self.tableWidget.setRowCount(7)
for i in range(7):
item = QtGui.QTableWidgetItem()
self.tableWidget.setVerticalHeaderItem(i, item)
self.tableWidget.verticalHeaderItem(i).setText("Item " + str(i + 1))
for i in range(6):
item = QtGui.QTableWidgetItem()
self.tableWidget.setHorizontalHeaderItem(i, item)
dock.setWidget(self.tableWidget)
self.addDockWidget(QtCore.Qt.RightDockWidgetArea, dock)
# Lower table widget
dock = QtGui.QDockWidget("Lower", self.centralWidget)
self.tableWidget_2 = QtGui.QTableWidget(dock)
self.tableWidget_2.setObjectName("tableWidget_2")
self.tableWidget_2.setColumnCount(6)
self.tableWidget_2.setRowCount(7)
for i in range(7):
item = QtGui.QTableWidgetItem()
self.tableWidget_2.setVerticalHeaderItem(i, item)
for i in range(6):
item = QtGui.QTableWidgetItem()

I have a simple python QT multiplication program. There are 3 fields, first random number(read only), second random number(read only) and third line edit for user to input result. If first * second = result then show Right Label, else show Wrong Label. I would like to replace exit button with play again button, so when the user press it, to regenerate random numbers and clear all result labels and user try again.

Let's say I have a simple window with three controls: a combo box, a push (toggle) button and a text edit control.
To spice it up, I needed the algorithm to run in a thread (while the toggle is pressed), but I guess the solution to the main problem I have won't be influenced with that
When the toggle button is pressed, I want to read the current ComboBox value and update the TextEdit's value.
This is the approach I've tried and failed to do it. Maybe it's a stupid mistake or I should change the design at all (would QML help in making this a bit easier?):
