  Actually the statement is Spot On -- and explained pretty much that way within their own documentation -- further Qt View does not require that you use a Qt Model (if I remember correctly) those are just nice tools and as such you do not need Qt Models to render a Qt View -- aka it works both ways So basically you are splitting hairs -- so okay yes they are not exactly a single entity -- BUT when used together they are not distinct autonomous entities either due to the fact they are tightly bound to one another making them pretty much a single non-separable entity if you plan to use them as prescribed Further yes the Qt Model (aka Controller) entity can be designed to be autonomous from the Data Source but your methodology was not doing that -- and when I say promoting it I am saying it is the idea you are putting forth as a possibility as no one else is putting that idea forth -- again you are splitting syntactical hairs when you say you are not promoting it Next those particular tools are not only not the best but perhaps one of the worst ways to implement said connectivity as I outlined -- yes but rarely (to almost never) is using an axe as you suggest a tool that one should use to pound a nail with using your analogy Look in a nutshell -- what I try to put forth are the concepts that are best to use in most if not all situations -- I rarely toy around with things (regardless of who provides them) with tools that utilize inferior methodologies such as those that do not implement a true MVC structure

  Well without seeing the code you use to create the object you are passing in -- it is hard to see what you might or might not be doing wrong -- better yet supply an MRE (Minimal Reproducible Example) that shows this functioning and produces the same error you are getting when it is run --- then we can help you troubleshoot your bug so much more effectively and quicker to boot

  @SGaist said in alignment for QCheckBox in QTableWidget: Why not use the Qt.ItemIsUserCheckable flag to get the checkboxes you want rather than widgets San you are doing ? Widgets set like that will not respond to any role because they are not part of the rendering of the model. I originally went with this and had issues with how I coded it, so I went with the checkbox route. But a clear head does wonders, and I did it this way. Thank you guys.

  Okay using the above file contents and restructuring you code a bit and removing the elements that were not doing anything currently -- which I am sure you can add back in now so they work appropriately with the new code layout -- here is a version that I hope helps you understand how to go about doing some of what you wanted to do as well as showing other aspects of it to help make it clearer over all --- note instead of call backs to your Parent you could use Signal/Slots but unless you are going to be Threading it -- it really is not really necessary to add that level of complexity from PyQt5.QtCore import Qt #from PyQt5.QtGui import from PyQt5.QtWidgets import QApplication, QWidget, QGridLayout, QVBoxLayout, QFrame from PyQt5.QtWidgets import QLabel, QPushButton, QLineEdit from zTest_03 import ObjectEncoder as objEncodr class TopFrame(QFrame): def __init__(self, parent): QFrame.__init__(self) self.Parent = parent self.setFrameShape(QFrame.Box) self.setFrameShadow(QFrame.Sunken) #

  Cheers, Yeah I don't think stylesheets will get me where I would like to go. So it tried to subclass a combobox and override the paintEvent. I had a look at the source cpp and ~think i got it... :P seems to work atm, not sure how safe this approach is though. I still need to add the logic to repaint a changed selection: from PySide2 import QtGui, QtCore, QtWidgets class CustomComboDelegate(QtWidgets.QStyledItemDelegate): def __init__(self, parent=None): super(CustomComboDelegate, self).__init__(parent) self.text_default = QtGui.QColor(199, 199, 199) self.text_hover = QtGui.QColor(255, 255, 255) self.cell_default = QtGui.QColor(67, 67, 67) self.cell_hover = QtGui.QColor(43, 43, 43) def paint(self, painter, option, index): painter.save() value = index.data(QtCore.Qt.DisplayRole) painter.fillRect(option.rect, self.cell_default) painter.setPen(self.text_default) painter.drawText(option.rect, QtCore.Qt.AlignCenter | QtCore.Qt.AlignVCenter, value) if option.state & QtWidgets.QStyle.State_MouseOver: painter.fillRect(option.rect, self.cell_hover) painter.setPen(self.text_default) painter.drawText(option.rect, QtCore.Qt.AlignCenter | QtCore.Qt.AlignVCenter, value) painter.restore() class CustomQComboBox(QtWidgets.QComboBox): def __init__(self, parent=None): super(CustomQComboBox, self).__init__(parent) self.__hovered = False def paintEvent(self, event): data = self.itemData(self.currentIndex(), QtCore.Qt.DisplayRole) if data: p = QtWidgets.QStylePainter(self) p.setPen(self.palette().color(QtGui.QPalette.Text)) opt = QtWidgets.QStyleOptionComboBox() self.initStyleOption(opt) p.drawComplexControl(QtWidgets.QStyle.CC_ComboBox, opt) painter = QtGui.QPainter(self) painter.save() pen = QtGui.QPen() pen.setColor(QtGui.QColor(199, 199, 199)) if self.__hovered : painter.fillRect(opt.rect, QtGui.QColor(43, 43, 43)) painter.setPen(QtCore.Qt.yellow) painter.drawText(opt.rect.center(), data) painter.setPen(QtCore.Qt.red) painter.drawText( opt.rect.center().x() + QtGui.QFontMetrics(painter.font()).size(QtCore.Qt.TextSingleLine, data).width(), opt.rect.center().y(), "(+)") else: painter.fillRect(opt.rect, QtGui.QColor(43, 43, 43)) painter.setPen(QtCore.Qt.yellow) painter.drawText(opt.rect.center(), data) painter.setPen(QtCore.Qt.red) painter.restore() else: super(CustomQComboBox, self).paintEvent(event) def mouseMoveEvent(self, event): if self.rect().contains(event.pos()): self.__hovered = True super(CustomQComboBox, self).mouseMoveEvent(event) def leaveEvent(self, event): self.__hovered = False super(CustomQComboBox, self).leaveEvent(event) app = QtWidgets.QApplication([]) combo = CustomQComboBox() combo.setMouseTracking(True) combo.setItemDelegate(CustomComboDelegate(combo)) combo.addItems(['one', 'two', 'three']) combo.show() app.exec_() Is it worth to investigate setting up signals on the combobox to test the hover state and indexChanged or to manage this in the events? This is an area I'm not sure what methodology has the best performance/less maintenance

  @bemlun you should do yourself a major favor and stop using the Qt Designer -- it might seem easier on the surface but under the hood it is a horrible mess and just a major headache to work with -- further you are probably not using it for what it was actually designed for. That being said creating using python-qt as it was meant to be used -- is rather easy once you get used to it -- further what you end up with not only do you understand how it works but you can now easily work with all the elements of the Gui because you fully understand how they inter-relate -- if you need help on this just ask or shoot me a PM and I can get you hooked up with a free classroom like environment

  @Jim-Gir I also meant to draw your attention to https://stackoverflow.com/questions/53296261/usage-of-qgenericargument-q-arg-when-using-invokemethod-in-pyside2. Which says there still isn't any Q_ARG in PySide2 and you can't do what you with no workaround :( As they point out in the answer that is a bug, it does not matter if it is QString or str, which still remains in PySide2 and unfortunately there is no workaround – eyllanesc Nov 14 '18 at 15:35

  My first suggestion is stop using the UI Designer as you never learn what it is you are working with -- further it creates very crappy code that is not proper python-qt. If you would post that python UI code I can show you how easy it is to make it actual python-qt code and when you see that you will get a better understanding of what your objects are actually doing and work

  @CKurdu I know nothing about QML, only about QAbstractListModel. If you are re-loading the whole data such that rowCount() changes, I'm thinking dataChanged is not enough, as that expects data inside existing rows to have changed, but not extra rows inserted/removed. I'm thinking you should be using https://doc.qt.io/qt-5/qabstractitemmodel.html#modelReset Note that if a model is reset it should be considered that all information previously retrieved from it is invalid. This includes but is not limited to the rowCount() ... Or possibly https://doc.qt.io/qt-5/qabstractitemmodel.html#beginInsertRows etc. if you want to do it by signalling as rows inserted/removed.

  Wait wait wait .... I am not sure how far this discussion has got but this seems woefully wrong way to do this The process flow should be --- Start Program Call Record_Audio Main Window Switch to Processing Window Call Recognizer Call SpeechConvert Call OtherProcessingFunctionsIfNeeded Switch to DisplayResults Main Window As such you never destroy the Main Event Thread as there is no need to -- you just switch between the various Windows you are using -- and if you sub-classed these various windows you can encapsulate what they do such that should you need a change to a single piece it you can easily do that without affecting any of the other pieces Create a Main Event Thread -- running a Window -- running some computational functions -- destroying the Main Event Thread and creating a new one to run another Window --- is far more complexity that is required and simply bad methodology

  @janhein_dejong nice in depth perusal of the inner workings nice to know this but for most beginners it is not going to worth a whole lot ;-) just too much information --- the basic principles I believe I pointed out -- and yeah you can use a multiprocessing to do this or you could have learned how to handle Event driven processing with Threads properly as well. I am not saying multiprocessing is the wrong solution -- but you are adding an additional layer of complexity that I am not sure was even necessary. K.I.S.S. (Keep It Simple and Smart) is always the best way to go in any program and I think a simpler solution just might have worked. Also keep in mind an issue with Multiprocessing is that the Sender sending data down a pipe must notify the Receiver that data has been sent -- as far as pickling is concerned in most (but not all) situations where you might need this the data you are sending is a non-issue -- you just have to make sure you do not send anything that cannot be pickled Still in order to set up the communication Pipe effectively you need to create a listening thread on the Receiving end that responds to the -- data sent message (which by the way is not a Signal because Signals/Slots do not work across Process boundaries) so it can pull the sent data from the pipe and then signals its parent that data has been received so you are still going to be dealing with a Thread and needing to be sure you are handling the Event stuff correctly Again thanks for that extra information -- I hope this helps you understand what you just stepped into ;-) @janhein_dejong said in Show QProgressbar with computationally heavy background process: In principle, mixing these types of threads in Python should not be a problem. Although the GIL enforces that only one thread is running at a single instance, the operating system in fact splits the processes up into smaller instructions, and switches between them. If a thread is running, it has the GIL and executes some of its instructions. After a fixed amount of time, it needs to release the GIL. Once released, the GIL can schedule activate any other 'runnable' thread - including the one that was just released. I want to say to this that "In principle" is kind of like saying "In Theory" -- and the take-away from this is while this is kind how it is supposed to work in actuality it does not work this way -- in short if you set up an endless while loop within a single process I can pretty much guarantee that your GUI is going to freeze up as that is the reality of what happens. Thus as I said you must learn how to handle Event driven code in a proper manner so that these secondary tasks remain secondary tasks and do not end up taking over the CPU rendering the rest of your code inert

  @Niagarer said in Widget class from pyside2-uic ui class not shown when adding to a tab widget: I just convert my UI files to python scripts with PySide2-uic. Is there something wrong with that? The code looks pretty efficient to me... I think it and using Qt Designer is fine, with about the same advantages & disadvantages as other GUI designers. @Denni-0 strongly objects to it. It basically boils down to whether you want a GUI designer or prefer to code your UI dynamically yourself, they both have pros & cons.

  @JonB Thanks that makes sense @Denni-0 I'm not sure I follow you. How can we explicitly set the image swap on only the last cell? Keep in mind the table is expandable so i cant make an image the size of the row. I saw that there is a setIcon() on the QTablweWidgetItem that places the image not tiled, but i cant seem to find a way to align it to the right :/ I have a working hacky solution atm... I added a new column on the right and replaced the item for a QLable. That way I can set a dynamic property on it. I then have a callback every time currentCellChanged() to manage the current selection and update the dynamic property of each rows QLable. I have to load the style sheet every table change though.... Any better solutions??

  In docs https://doc.qt.io/qtforpython/tutorials/basictutorial/uifiles.html#generating-a-python-class we are shown creating a class class MainWindow(QMainWindow): I thought the pyuic produced this class definition, and same for uic with C++. That is what I expected. I think not now. You are supposed to write that yourself. They only produce Ui_MainWindow class. Right? It turns out the code I am working on does not take that approach, hence my confusion. It does not create any MainWindow class at all. Instead it creates a plain QMainWindow instance and then passes that to the generated Ui_MainWindow.setupUi(). That changes the issue for me, I shall have to ask the author why that approach was adopted.... EDIT OK, he said "no reason". So now I am free to create my own subclass of QMainWindow in code, and thereby override closeEvent() as required.
