@Kira said in Declare the given statement in h file and initialize in cpp file: session_inception = std::unique_ptrtensorflow::Session(tensorflow::NewSession(tensorflow::SessionOptions())); You can simplyfy to session_inception.reset(tensorflow::NewSession(tensorflow::SessionOptions())); no need to call the move constructor

@mrjj the transparency is working now in qt 5.5.1. The code is given below, QLabel* bg = new QLabel(&w); bg->setGeometry(100, 100, 200, 200); bg->show(); bg->setText("Hello"); bg->setStyleSheet("background-color: yellow;"); QPushButton* trans = new QPushButton(&w); trans->setGeometry(100, 100, 200, 200); QPixmap pixmap("transparent.png"); QIcon ButtonIcon(pixmap); trans->setIcon(ButtonIcon); trans->setIconSize(trans->size()); trans->setStyleSheet("border: None"); // It will make the image button as transparent trans->show(); If I have changed background color of QLabel, it will transparent to the image button window. I hope it may help. Thank you all.

Is the error coming from building the VTK library or from using the VTK library in your project? If it's the first then post OS, compiler, architecture, Qt Version and Cmake version used. If it's the second please show us your project file

Solution for this issue has been found in the below forum. Thanks all for the support. https://forum.qt.io/topic/97995/can-qt-access-windows-sdk-functions-in-a-third-party-static-libraries/3

@Christian-Ehrlicher win32:LIBS += -L"C:\Program Files (x86)\Windows Kits\10\Lib\10.0.17763.0\um\x86" -lUser32 I added this and the issues solved. Thank you @Christian-Ehrlicher for the support.

@wrosecrans thanks for your help!

Thank you for your reply.

@Ratzz and @Christian-Ehrlicher thanks to both of you for replying. I've tried the example in qt dir and now it works. I also had to add these lines in CMakeLists.txt : qt5_add_resources(RSC completer.qrc) # if next line is not added -> error but it will still work set_property(SOURCE qrc_completer.cpp PROPERTY SKIP_AUTOMOC ON) add_executable(completer ${SOURCE} ${RSC})

Hi and welcome to the forums My best bet is that your openGL is so new that glBegin(GL_QUADS); is no longer supported in the core profile/openGL 3.3 ( i think) Its part of the so called old fixed pipeline. It might be possible to request older profile but would be better just to use modern openGl. https://learnopengl.com/Introduction https://learnopengl.com/Getting-started/Hello-Triangle

Hi, From the looks of the error, your application is indeed innocent and that's one thing Apple needs to fix.

Yea, I spent a good chunk of time staring at the example and try to get it working in my context but it didn't quite work out. I eventually just made an invokable getter method that takes the index and using signals from the c++ class I tell the QML file when to update it's respective values with the getter method into my list.

@dheerendra I'm working on checking all of the plugin libraries and I think I found my problem. I had to enable plugin debugging and it's failing to load because it cannot find the plugin xcb. So I copied over the libqxcb.so to the other system but still ran into problems. The system I'm trying to get it running on is a 32-bit system but the libqxcb.so is 64-bit. This also seems to be true for the libqtvirtualkeyboardplugin.so in the /plugins/platforminputcontext. Now I'm wondering if there's a version of libqxcb.so that's even 32-bit or if the qtvirtualkeyboard can be loaded onto 32-bit systems. I'm still looking into this part as this is something I overlooked.

Hi Well TextEdit can sort of do it using @J-Hilk idea. [image: A8w6hQ.png] using [image: Iqhnx0.png] [image: Ikm46l.png]

QProcess

You can use the libraries directly. See http://doc.qt.io/qt-5/third-party-libraries.html and http://doc.qt.io/qtcreator/creator-project-qmake-libraries.html

@kshegunov said in Difference between Qt 5.6.x and 5.7.x ; floating precision: Thanks a lot to everyone.

@mrjj Yes you were right, now it's ok, i need to use QToolBox instead of QWidget. Thanks for help :)
