Qt for Python

@markugra your solution for windows 10 worked for me. Thanks!

Hi, You have here an example of how to build an area series. It's in C++ but easily translated to Python. I think it should provide you with the information you are looking for.

@Qt-Bot05 Well, it seems to me you're using Y values the wrong way round for upperSeries and lowerSeries! But I think the docs imply that doesn't actually matter, though you might want to verify by swapping. Also, you're testing with just 2 points, it's an area series so why would you test with less than 4? What are you expecting to see? Anyway, your issue is probably something else. Have you checked it works for you for other than QAreaSeries?

@hachbani Yes, like I wrote at the end, this way you never create any QCheckbox yourself, and you don't go into editable mode with createEditor() etc. The code is only to do with getting the checkbox centered. Just start out with using CheckStateRole to store the state and ItemIsUserCheckable in the flags. This allows the user to check the box without anything further.

@jsulm said in It looks like showFullscreen() and showNormal() have different effects: parents layout Thanks, that helped me out. I tried using setParent, but forgot to add it back to the parents layout.

@hachbani As @SGaist said. Make sure your Add button calls accept(), or done() with a particular value, to exit the dialog. And Cancel button should call reject(). Not just close() as you have now. That is what QDialogs should do. Then the return result of the exec() will give that value to the caller, for you to examine.

@JonB Is it possible to take the data from the table and store it in some Python structure, for example, a list and then put it in a QTableView?

@LaGuiche55 Following your question, I have uninstalled and reinstalled those components and now it works . I have uninstalled Qt with ./MaintenanceTool pip uninstalled PyQt5 pip uninstalled matplotlib sudo apt-get install qt5-default Qt install with online install executable pip install PyQt5 pip install matplotlib Thanks

@Black-Cat You can read resources out of a resource file. But you cannot but every time that I need to change this file I need to save the new file in resources and reload the resource file and this is inviable to me. even if it's what you say you have to have! Resource files are read-only, generated at compile time. You can of course change which file you read in that string, if you have a variety of files saved in the resources. But you cannot write back anything to a resource file at runtime. Nor should you need to. Where are these "new file"s, how to you propose to generate them at runtime? If you do have to save to external file, you can save to the actual OS file system and then read that back as a png or whatever, but not as an embedded resource.

@lumpynose said in window too big: Or, how can I make a window that's 800x600 pixels? https://doc.qt.io/qt-5/qwidget.html#resize-1

Great ! 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 :-)

@Black-Cat With the little code it is impossible to help you so if you want more help then you must provide a minimal and reproducible example

@Lucas_1603 As per the code in the RuntimeError you show, it is not the code you in your claimed code. Either you are not showing the code you are executing, or there is more going on elsewhere in your Python app than you show.

@goingwtheflow You have two .py files, each with their own main, hence standalone programs. How do you intend for them to interact? One would be better without the main. When you post code, please use the Code icon on the toolbar to make your code legible.

Install and use Qt Creator - it comes with contextual help included.

Hi and welcome to devnet, It seems you might be mixing two things here. .ui files are generated using the standard Designer. Can you explain exactly what you are currently doing ?

@JonB Honestly fair enough, thanks a lot.

Hi @SGaist, I've just created a new environment using conda and installed everything from scratch, now it works fine Thank you so much

Hi, Call setEnabled(false). Beware of your use of cell widgets. It's not meant as a solution to populate full columns.

Hi, Can you provide a minimal runnable script that shows that behaviour ? Which version of PyQt/PySide are you using ?
