@Pl45m4 said in Custom widget using and extending Qt's pImpl: It was just about the naming?! Is this the way? :) I would say yes.

@PValentine As @Christian-Ehrlicher has said, you cannot read the effects of stylesheet in Qt code. Try not to set font in code at the same time as using stylesheets. Are you aware there is a QTableView::item CSS selector? This affects all the table's items, there isn't a way of selecting individual ones.

@starkm42 Yes, if it is only multiple slots in a thread, including the main one, which access a resource then everything is occurring serially, no locking would be needed.

@JonB I have also considered whether it is an issue with Android permissions, but I don’t know where to get the answer.

@Pl45m4 said in QRemoteObjectHost connected nodes: @beecksche Dunno if it's the right signal but maybe https://doc.qt.io/qt-6/qremoteobjectnode.html#remoteObjectAdded https://doc.qt.io/qt-6/qremoteobjectnode.html#remoteObjectRemoved to keep track of the current connections yourself That's what I thought at first. But if I understand the documentation correctly, the signal is emitted on enableRemoting(). The QRemoteObjectSourceLocation argument also contains no information about a client, only the hostUrl and typename.

@Paul-Colby Thank you for that detailed answer. I'm using qmake so I guess for now I will stick with that "old" structure. But your answer is bookmarked for future use :)

Further to @Pl45m4's observation, look at the prototypes of the functions you used to pass QwtDoubleRect objects to and you probably see that they now take QRectF @rock37 , what is the connection between the title of this thread and the content of this thread?

@SGaist thank you for your help

Hi, The usual way would be to follow the implementation done by the other plugins. Then you have to deploy it using the same folder structure in your application folder and it should be made available as the other plugins. If not, then you can copy your plugin beside the others in the Qt installation.

Hi, In addition to @Pl45m4, you don't print any information if the opening of the serial port failed. Doing that will help track the issue.

@NightShadeI Possibly related is that, on Windows, QtCreator's model editor used to have the same defect until the recent upgrade to QtCreator 12. It would leave behind graphics artefacts as you moved elements around. There may be clues in the QtCreator sources. By model editor I mean what you get when you "Add new..." => Modeling => Model

Hi, Based on the AWS documentation, the answer is "currently no".

@Seb-Tur You will find that you cannot bind to the list of values for an IN clause. Not supported by the driver. I think you would have to produce the actual IN ( ..., ... ) as a string for the query. Doubtless with caveats about injection. There may be MySQL possibilities to work around this, I don't know.

In fact I was wrong, the linked topic is about QTabWidget not QTabBar Anyone one know how I can do what is described ? ie adding a widget to the qtabbar. Thanks

Use a debugger and see from where it comes and fix your code.

@JonB , thank you, I will take a look now.

@richferrara said in Qt hangs when re-scaling Y axis: It doesn't happen every time -- only when the user selects certain data fields to be plotted. But then every time?! How do you update the x-axis? Via setRange? What else is happening while the axes are getting updated? Does the behavior change if you remove the axis and add a new one with updated scale? You could try that just to make sure that it's the axis and not some unwanted stuff happening with the data
