You can pre-compute the BMP in a separate thread and then access the finished image in the main thread to use it in the splash screen.

I had the same problem using virtual environment and pyqt5. This solved the problem: set "QT_PLUGIN_PATH=%VIRTUAL_ENV%\Lib\site-packages\PyQt5\Qt5\plugins" and I added this to the virtualenv activation script .... @set "PATH=%VIRTUAL_ENV%\Scripts;%PATH%" @set "QT_PLUGIN_PATH=%VIRTUAL_ENV%\Lib\site-packages\PyQt5\Qt5\plugins" @if defined _OLD_CODEPAGE ( ....

@alan02011114 I don't understand what your question is. As the error message tells you, your slot requires a dfreceived/second position argument and you are not supplying it in your lambda so you get the error.

Okay. I found a solution myself by using the following command... Should be solved for now :D pixmap2 = pixmap.scaled(1920, 1080)

@jsulm Thank you very much ! It's exactly what I needed. In the top !

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 :)

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

Thanks for the reply @SGaist. What I wanted was to update some data (in form of text) from python backend, most of the tutorials I saw were based on using signals and slots. were as I only needed a slot to read without any triggering signal. Though I've been able to finally figure it out and spending this much time actually made me understood it more. I used QTimer to refresh the backend function every half a second.

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 [image: 399f382c-66a6-4864-923c-8fe7b55563dd.png]

@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() )

@Mindful i have this problem.~ you can explain better how you solve?

@aria_aa said in how too add an exciting ".ui" file to a "cpp widget application project"?: What should I do? clean up the build directory run qmake rebuild project Should work, code looks good. And another question: what is #include "ui_window_no_000.h" and #include "ui_window_no_001.h" in cpp files? there is no file such as ui_window_no_000.h or ui_window_no_001.h in project. These files are automatically generated from your .ui files by uic. It's part of the build process in Qt, same as with it running moc to generate meta-object functionality.

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 😊
