Hi, I would ask this question on the PySide mailing list. The method is also not available in PySide2 as it seems.

Ok, I've made a PoC for this issue, where both the "extra" tree element appears and when you try to load twice it will eat all the memory, freezing . I'm running Python 3.10.1 with PySide6 6.2.2.1 under Linux Fedora 35. I can't attach the zip file here, though you can download it from the following link: https://drive.google.com/file/d/1vBZDIAZGhnS_Gi-rFalpxZKgB5zqLh7a/view?usp=sharing Thanks :) EDIT: I finally caught the error! I was creating the model's root item and I was appending all the items in it, though I was also appending the root item to the model itself (see line 184 of the last example). It was as easy as that. Thanks for the support though :)

Since you use a QTableWidget, create a QTableWidgetItem with an icon from your image.

Hi, Load your picture in a QImage, rotate it and the make a QPixmap out of it before setting it on your QLabel.

pyuic has a couple of options, among them there is one called --from-imports that might solve your issue. https://www.riverbankcomputing.com/static/Docs/PyQt5/designer.html#pyuic5

Since you have a pretty reliable way to trigger the crash, sure, open a report providing the step by step instructions to reproduce this :-)

@shashankx86 and if you want a Python example using it, PySide has a couple of examples in the documentation page, like https://doc.qt.io/qtforpython/examples/example_widgets_layouts_basiclayouts.html?highlight=layout

@CristianMaureira @JonB Sorry... I mean

@CristianMaureira Thanks for the answer, dude, but I already know about QMovie, is it really possible to do a lot of gifs (20-30) with this in one window?

@JonB argh! I spend a whole day yesterday to figure out how to make it work, and all I needed to do is to write mySignal=Signal() not in the init, but in the class body! Jeeeez. Thanks a lot! Your advices and link helped!

@eyllanesc I am sorry but right now I can't. Downgraded from 6 to 5. I will wait for the best stable version of QT. Thanks a lot! P.S.: I was using fromImage method which is necessary for my app flow. Not type conversion with the class call (such as QImage() )

@haseeb These are slots attached to the same object-signal. They will be executed (when the signal is emitted) in the order in which you did the connect()s. I thought you want to start the thread first and then get it to execute self.worker._check_price(), but maybe I misunderstand. If you say it's OK to first call self.worker._check_price() and then call self.thread.start() that's fine, I had the impression you need to start the thread before asking the worker to check the price, but I defer to your knowledge of the code.

@ametefe said in PYQT5 Stacked Widgets not resizing: Do you have any other way to call another widget I do not know what this means. If you use Designer to produce .ui files, you can either run the Python uic to generate Python .py file code from it or you can use UiLoader thingie to load the file dynamically at runtime instead of generating code for it. Exacts depend on whether you are PyQt or PySide, the alternatives are documented somewhere in introductory topics for the two Python bindings. I don't see that either of these approaches will have any effect on the runtime behaviour of your widgets/QStackedWidget, if that is what you are expecting.

When using that technique you should rather determine the location of the current script using __file__ so that you don't hard code the path in it.

Thanks @SGaist! I just got a solution on StackOverflow, so I’m marking this as solved, but it’s always great to see how the pros do it, so I’m definitely reading about KExtraColumnsProxyModel too 😊

@JonB said in QSqlDatabase, SQLite and Decimal (on python): By the time MySQL's decimal type hit Qt's model it gets converted to float, even though Python (not C++) has a decimal type Oh, thanks for mentioning this fact. I didn't know it and expected that Qt would be able to handle Decimal itself. This way it appears I'll need to do similar job and also modify QSqlQuery to handle data updates properly. I'll think about it. Thank you very much for information.

@D-Drum Hi super :) I agree there could be some more info about this in the docs.

Do not use setCellWidget. Generate your images and store them in your model. Either use the decoration role to show them or a dedicated item delegate.

Hi, You might want to check the pydroid project. On a side note, please write your thread title in English as well. There's the International sub forums for native languages.

Hi and welcome to devnet, What is the back trace of your crash ?

@JonB Yeah,I abandoned the monkey patching thing. It's not a good way to edit widgets. I'll follow your promote solution.I'll try google it.I didn't even know there is a promote feature before. I'm not a native english speaker,hope my codes and typos didn't make you angry. Really appreciate the help of yours.Thanks alot.

You're welcome ! Since you have it working now, please mark the thread as solved using the "Topic Tools" button or the three dotted menu beside the answer you deem correct so that other forum users may know a solution has been found :-)

Solved. After lots of looking around I was able to find this issue with the recomendation NOT to use the python version that comes from Microsoft's Windows Store. Instead download the official python version from python.org https://bugreports.qt.io/browse/PYSIDE-1245?focusedCommentId=527588&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-527588

You likely forgot the .ui between the self and .label. Working with designer based UI requires some getting used to since you have all the code in the same file. You have the Ui_XXX classes for the aesthetics of your widget (and which is auto generated) and the corresponding XXX that is for the logic you want to apply.

@J-Hilk Thanks for the response, I'll look into that stackoverlfow thread

@Qt-Bot05 @JonB said in loadUi from outside directory: you can [go] upwards via ../something

@Suryansh-Singh Try to set Qt::NoFocus as https://doc.qt.io/qt-5/qwidget.html#focusPolicy-prop or remove focus from the button using https://doc.qt.io/qt-5/qwidget.html#clearFocus

Thanks @JonB and @SGaist for your suggestions, they led me to the right path. I tried to find a QVariantMap signature for QtPy5 but couln't find any. But after a bit more googeling i found QVariant which returned an Qt.Qml.QJSValue object.... which after quite a bit more googeling has to be transformed again with .toVariant() to be accessible with python. I don't fully grasp why, but it works now :) So for anyone stumbling across this on their google journey: main.qml stays the same as above to pass a json object. But in Python you need: main.py: from PyQt5 import QtCore, QtGui, QtQml ... class controller(QtCore.QObject): ... some working functions for buttons here... @QtCore.pyqtSlot(QtCore.QVariant) def saveSettings(self, saveditems): saveditems2 = saveditems.toVariant() print(saveditems2["textfield1entry"]) which prints the value of: textfield1.text

@SCP173 Try with: import sys import random from PySide6.QtGui import QGuiApplication from PySide6.QtQml import QQmlApplicationEngine, qmlRegisterType from PySide6.QtCore import QUrl from PySide6.QtCore import QObject, Signal, Slot class NumberGenerator(QObject): def __init__(self): QObject.__init__(self) nextNumber = Signal(int) @Slot() def giveNumber(self): self.nextNumber.emit(random.randint(0, 99)) if __name__ == '__main__': app = QGuiApplication(sys.argv) engine = QQmlApplicationEngine() qmlRegisterType(NumberGenerator, 'Generators', 1, 0, 'NumberGenerator') engine.load(QUrl("main.qml")) if not engine.rootObjects(): sys.exit(-1) sys.exit(app.exec()) import QtQuick 2.0 import QtQuick.Window 2.0 import QtQuick.Controls 2.0 import Generators 1.0 Window { id: root width: 640 height: 480 visible: true title: "Hello Python World!" Flow { Button { text: "Give me a number!" onClicked: numberGenerator.giveNumber(); } Label { id: numberLabel text: "no number" } } NumberGenerator { id: numberGenerator // Signal argument names are not propagated from Python to QML, so we need to re-emit the signal signal reNextNumber(int number) Component.onCompleted: numberGenerator.nextNumber.connect(reNextNumber) } Connections { target: numberGenerator function onReNextNumber(number){ numberLabel.text = number } } }

Try with: MAX_HEIGHT = 4096 # Arbitrary value class HeaderView(QHeaderView): def __init__(self, parent=None): super().__init__(Qt.Horizontal, parent=parent) self.setStyleSheet( "QHeaderView::section{background-color: #ffffff; " "font-weight: bold; " "padding-left: 2px; " "color: #3467ba; " "border:0px; " "border-left: 1px solid #ababab; " "border-bottom: 1px solid gray;}" ) self.setStretchLastSection(True) self.setDefaultAlignment(Qt.AlignCenter | Qt.Alignment(Qt.TextWordWrap)) def sectionSizeFromContents(self, logicalIndex): text = self.model().headerData(logicalIndex, self.orientation(), Qt.DisplayRole) alignment = self.defaultAlignment() metrics = QFontMetrics(self.fontMetrics()) width = metrics.boundingRect(QRect(), alignment, text).width() heights = [] for i in range(self.count()): text = self.model().headerData(i, self.orientation(), Qt.DisplayRole) size = self.sectionSize(i) rect = QRect(0, 0, size, MAX_HEIGHT) heights.append(metrics.boundingRect(rect, alignment, text).height()) height = sorted(heights)[-1] return QSize(width, height)

If that: @ZZR69 said in class HMI to another class how make the dialog?: Alstom2570class() #appel de la fonction permettant de sortir de class interface graphique Qt refers to: @ZZR69 said in class HMI to another class how make the dialog?: def Alstom2570class() then you have an issue in your understanding of how Python classes work as well as the signals and slots concept of Qt. I would recommend to take a step back and start with a minimal application showing a QSpinBox and a QLabel. Then connect the spin box to a slot that will update the QLabel with its value. Once you have that working, you'll be able to implement your application.

I have changed ":/newPrefix/text.pdf" from "qrc:/newPrefix/text.pdf"

Hi and welcome to devnet, That is indeed something strange but why are you using it in the first place ? QWidget already has support for resizing.
