[Interest] QModbusTcpClient - More than one Modbus ID query in TCP Package

Hello dear all, I already wrote a post to the QT forum and got the suggestion to post my question at this site. Currently I'm using the class QModbusTcpClient. I want to read sequentially values from different Modbus addresses. In a thread I'm calling the following function via signal slot. void

Re: [Interest] Odd behavior with QTcpSocket::waitForReadyRead()

> int msecs = timeout * 100 I'm pretty sure that's the conversion for usec, not msec. Note that in most cases there is a hard-coded 75 second timeout TCP read timeout from the early days of the internet. And anything over 60 is likely to to dropped by firewalls. You shouldn't be using wait

Re: [Interest] Odd behavior with QTcpSocket::waitForReadyRead()

I'm refactoring the old code (modeled on Stevens' "UNIX Network Programming") to use the more modern Qt paradigm of signals/slots for async communications. So, the need for using waitforReadyRead() is obviated. I'm guessing the timeout period being used greatly exceeds the underlying stack's

Re: [Interest] How to provide a component to a QML item?

Hi Jason I am not sure if I have understood you correctly, but I think I have used a similar approach in some of my apps to create a dynamic-content list. I have done that by aliasing the data property of the column item as follows //StandardScreenWithSpecificContent.qml StandardScreenWithSpecif

[Interest] How to provide a component to a QML item?

I've got a situation where I have a variety of items ("screens" in a stackView) where they have a similar structure, but the content differs. Example: Screen { Column { StandardScreenContent { } ScreenSpecificContent{ } } } But I'd like to do it like: StandardScreenWithSpecificConte

Re: [Interest] Qt3D - Render to QImage

Hi, I've began to look a the QRenderCapture code to implement the QBufferCapture node and I've found that the problem that Philip described may happen because of the render target format used. The debugger says that the render target is a RGB8_UNorm which is not considered in the big switch case s

[Interest] Odd behavior with QTcpSocket::waitForReadyRead()

I'm porting a TCP/IP client from wxWdigets to Qt. I've tried this under both 5.4.2 and 5.6.2. I have a user-configured timeout value for network reads. The default is 300 seconds (5 minutes). I am feeding that to QTcpSocket::waitForReadyRead(), and it's basically ignoring--worse, it's gener

[Interest] Update breaks version

I have Qt installed on Windows using MinGW. I was at 5.7.0 and updated via the Maintenance tool to get to 5.7.1 and Creator 4.2.0. My programs build but when I deploy them to systems with 5.7.0 dlls they don't work. I thought the dlls were compatible through minor revisions? ___
