@CJha The problem is that you can't just replace something in a file if new value has different lenght than the old one. In this case you need to read the file into memory, replace the value and write it back. To read such an ini file and replace something there Qt needs to know how to interpret the data it reads.

@Rockerz In a signal you create for this purpose you should pass as (a) parameter(s) whatever information you want to pass, e.g. a string you want displayed. A slot you write in your existing main window should receive that string and do whatever on the UI side, such as displaying it. You need to understand conceptually why creating a new MainWindow() will never be right and will never address your existing main window instance.

In that case, the likely easier path would be to follow the deployment steps for the Linguist you want to share and provide it as an archive (or use the QIF for that)

@AnneRanch Either start process with a delay QTimer::singleShot(), or through meta object system QMetaObject::invokeMethod(), or move it to another thread, or let the app process events before calling your blocking code: qApp->processEvents(); text = BTUL->ProcessCommand_Raw(" hcitool "," scan " );

@micha_eleric Impossible! My demo runs fine and I'm using Qt version 5.6

@JonB , thank you for your interest. I've found an old post where a similar problem to mine was posed (Run python script in Qt). In that case, a user wanted to run Python directly from a QProcess, while I intend to run indirectly (through a batch file). But the problem was exactly the same in both cases, and hence @NotYourFan 's solution has worked for me too. Regards,

@ademmler I use "-w width=950" You see the stringlist match.

@ChrisW67 Thank you, that fixed it! My bad for missing that. Calling QNetworkInformation::loadDefaultBackend() before calling the features function worked

@Rocky-Plantchair glad to hear it. You might want to mark your topic as solved.

I think what you want is Qt::DecorationRole. See here for more information.

@JonB , it looks like both signals are emitted. I realise it starts with no data, thats why when I set-it up with data I have a call to QSignalBlocker to prevent it emitting signals.

@mark-waston To use industrial cameras in Qt Application. As per my experience I suggest you should use Your camera SDK, Even i am also using industrial camera Like Baumer, Basler, HikRobot, ImagingSource, Matrix vision, Point Gray(Flir) in my Application. Even industrial Camera SDK provide almost every functionality like Connect Camera, Acquisition Control, Analog Control, etc... And without build own QtMultimedia plugin it''s may be not possible,

@SGaist Hi, this isn't so easy to explain. I can even have several device threads that are to interact with the hardware, whereby only the first thread sends the request to the hardware. The other requests are skipped. The hardware sends the response asynchronously, so I have to wait for it. During this time, the other threads have to wait in the function they are currently in. They cannot leave the scope in between.

@sierdzio said in QMouseEvent::pos() returns different values on different OS: No, it is not related to the style selected. I checked on Windows and it has no shift on Windows Vista, Windows and Fusion.

@Pl45m4 You can also moc a .cpp file even though it's unusual. e.g. when you've a small private, object-derived class in your cpp file (as some Qt source code is doing it) instead moving the class definition into an own foo_p.h. I mostly use it for small testcases only containing a main.cpp - then you need to include <main.moc> and cmake is doing the rest (instead fiddling around with a Makefile).

@Damian7546 Did it work? I think the form you write was declaring as Namespace::Struct, not Struct::struct.
