@kent-dorfman I tried. The lambda is not executed.

@bartoszpaj said in BindValue() in QPSQL is not working?: driver()->hasFeature(QSqlDriver::NamedPlaceholders) returns false. Good catch. I think it's because support for PostgreSQL 10 was added in a later version. If the version is not known to the driver it will fall back to the oldest.

@ronaldviscarral Thank you very much it works now.

Ah ha! Solved. I was using the wrong version of qmake to build the project. All sorted now.

doubtful...the json is a document format. so, to be parsed correctly it needs to be cached somewhere. The readall() pulls the whole document into memory so that it can be parsed.

@sgaist that's right! Thank you! QLineEdit *myLineEdit = new QLineEdit(this); QAction *myAction = myLineEdit->addAction(QIcon("test.png"), QLineEdit::TrailingPosition); connect(myAction, &QAction::triggered, this, &MyClass::onActionTriggered);

If I'm looking at the doc, I see: Header: #include <QGraphicsSvgItem> qmake: QT += svg Have you add this to your pro file ?

@christian-ehrlicher That's what I feared . so , thanks, i will manage with this.

@sonichy said in How to recognize QNetWorkReply.Error() form QNetWorkManager.get() or QNetWorkManager.put(): QNetworkAccessManager manager; Just for clarify, is your instance of QNetworkAccessManager still alive at the time your slots are called ? Because as you are declaring it on the stack, it may be already destroyed and I presume it will also destroy internal QNetworkReply objects.

Where did you open that thread ?

@iammhz said in Threads in PyQt and opencv: when i click other buttons , they can't access the Webcam What if you just have only one method/thread to access the webcam, independent on which button is actually pressed, and when the image is captured then pass that image to the specific processing method/thread depending on the button/effect pressed. This way you'll avoid the bottleneck of "sharing" the webcam among threads

@christian-ehrlicher Yes I know. I was trying to state in my comments that I obtained the byte array and was continuing. I agree that was not clear. I have solved the issue - my test jpg file had a non-compliant embedded profile. Many thanks for taking the time to help!

@devoo Are you trying to change textureSize of QQuickPaintedItem Class ?

@ofmrew please be sure to post book name in https://forum.qt.io/category/6/announcements :) (when its ready)

The best method to solve dependence problem is setting the environment variable. ``` C:\qt\qt-5.13.0-deploy\bin ``` But you should know it is a bad method for multiple qt.

@jonb Okay, I got it. Thanks bro!

According to this video, it should be possible to run the application both locally and remotely: https://vimeo.com/304349023
