General and Desktop

Ok, I will look into it. Thanks for the tip!

It works!! Thank you!! You saved my day :) QByteArray rawImage = QByteArray::fromBase64(base64); I think this was the main missing part...

@mpergand I actually found the exact code they use on VLC Media Player and it is Qt code. Downloaded the VLC source code Found the media position slider in input_slider.h/cpp in the directory: vlc-3.0.16\modules\gui\qt\util\input_slider.h/cpp and the tooltip class in the same directory with the name timetooltip.h/cpp

@n-2204 said in Qtableview to Qtablewidget: I have Qtableview (Qstandrditemmodel) : Then why do you want a QTableWidget at all? QTableWidget inherits QTableView, and supplies its own internal model to use. There is nothing you can do with a QTableWidget which you cannot do with a QTableView and your own model.

@TheCipo76 And just so you know. The capture [=] means "capture all local variables, by value" ([&] would be the same but all by reference). In this case you only need i, so you could have written [i] here, or [i, j, ..] for individual ones. Just so you know if you want to use that or see it elsewhere in examples.

Thank you, your messages were really helpful! I now understand how these work a lot more.

@lfreeman6490 Hi What kind of errors ? make sure to read the docs as its a bit hysteric with the compilers https://pybind11.readthedocs.io/en/stable/basics.html The PyObject_CallObject API didnt work for you or why did you give it up so fast ?

@mrjj yes right!

@JoeCFD Now I get this error. [image: 1d6286e8-d567-4855-8f7c-093396b97940.png] I take it back so I stay at the end and if it worked, thanks man. include_directories(${CMAKE_CURRENT_SOURCE_DIR}/lib/include) unset(MYLIB CACHE) find_library(MYLIB NAMES libQXlsx.a PATHS ${CMAKE_CURRENT_SOURCE_DIR}/lib NO_SYSTEM_ENVIROMENT_PATH) target_link_libraries(untitled2 PRIVATE ${MYLIB})

So how does that get added in VS2019? I have added the concurrent module in general -> Qt Modules but do i need to add/change anything in the qmake section? If so under what section do i need to make the changes? Thanks

Hi, @hael1902 said in Import data from txt file to QTableWidget in Qt: TableWidgetDisplay When is that method supposed to be called ?

@SGaist thank you.

@Christian-Ehrlicher oh so it does but in a very long chain of inheritance... I thought it derived only from QAbstractItemView but then I didn't realise the chain is QListView:QAbstractItemView:QAbstractScrollArea:QFrame:QWidget

Great! Thank you.

Hi, unfortunately not. I had to develop a wrapper to a python 3d library, i.e., mayavi, which provides very good and customizable antenna pattern representation. If you're familiar with python I suggest to move to that platform for this purpose.

@SeyMohsenFls Hi Well you would create an Installer for your app and then bundle the SQL Express installer with that and make it install the DB system as part of your app's setup. https://www.hanselman.com/blog/download-sql-server-express Qt has an install maker but it has a hard learning curve IMHO I like this one https://jrsoftware.org/isinfo.php

@Driftwood Hi https://doc.qt.io/qt-5/qtimer.html#timerId

@JKSH said in Unicode in the C++ code: Thanks. So I settled on using wchar_t and also QString::fromWCharArray() and that is able to post text properly: editbox->setText(stuff.........);

It's been a long time since I used OpenGL. OpenGL version 1.1 to 2.1 handle power of 2 textures. I think it is with GL 3.0 that non pow-2 textures work. I think you have to explicitly create a GL 3.0 or above context. But I could be wrong. Also, try making a 256 x 256 or 256 x 512 or 512 x 512 texture.

@SGaist I found solution for it. I use share network from my PC to jetson nano device so it make different subset: 10.42.0.* and 192.168.1.* After plug both PC and jetson nano with same router, it worked Thanks for your support
