General and Desktop

@jsulm yes thanks now my application show the ui.

@sierdzio It seems that it is the MOC program can not handle "attribute", not g++.

so there's also .isPunct() to check for punctuation.

@Abderrahmene_Rayene There's got to be a way to do this without resorting to a text block. I just want the containing view to automatically resize to match the needed height of the text edit. The containing view is a table widget cell.

@JonB said: Which I have always regraded as devil's spawn Agreed. I see blockSignals() as an advanced tool to be used with great care and only when you're very aware of all consequences in given case. Similar to sender(). Definitely not something to be applied on a "let's see if it helps" basis.

@whatabout You would raise a bug report at https://bugreports.qt.io/

I found an interesting piece of information that -recheck-all is needed if it has been configured before.

@Paul-Colby Thank you

@Axel-Spoerl My bad! Actually, Qt 6.5.1 is being used and not 6.2

@ogoffart In your impementation of QDesignerContainerExtension::insertWidget, you can create your own custom widget instead of using directly the one passed as parametter (maybe you can just ignore it or you need to call deleteLater on it) I tried this and I'm pretty sure you can't do it in Qt 5.15 at least, you end up with a Qt Designer warning dialog saying that that's an unmanaged widget and you should use the domXml() instead (Heaven knows how); at some point later it makes crash the designer when adding a child to the custom widget page.

@SGaist He is using an iMac with AMD GPU - this would make it an intel cpu. @SPlatten I guess you are using qmake for your app? In any case what you could do: create an xcode project of your app with qmake and compile it using xcode. Follow this link to edit run scheme for the diagnostics malloc magic Xcode provides. Run with Xcode Hopefully this will lead you to your problem. Alternatively I think clang´s address sanitizer may be of help as well. For this to work sort of reliably you can add the following compiler flags to your app: -O1 -g -fsanitize=address -fno-omit-frame-pointer This should give reasonable performance while maintaining debugging capability. Note however that I have never used the Xcode approach on macOS. I am using CMake with the address sanitizer only. EDIT: AFAIR valgrind was never of much use on macOS and is much better supported on Linux.

Hi, From the looks of it, I would say that the transaction is what you are looking for.

@ChrisW67 A software that connects to Bluetooth Low Energy, which mainly uses Bluetooth modules, and the Qt version is compiled by Qt 5.12.11+VS2019. I tested it on two WIndows11 testers in the customer, only scanned the device, and then used spy++ to locate the pop-up program was caused by the second screenshot program

@sani1486 hi and welcome to devnet, Check the stackingMode property. It allows to check whether you see on widget at a time or all of them.

@StudentScripter great ! Then please mark the model as solved using the "Topic Tools" button or the dotted menu beside the answer you deem correct so that other forum users may know a solution has been found :-)

@SPlatten hi, You can add a widget to a QGraphicsScene and you get a QGraphicsProxyWidget that you can then add to your layout.

@marius-thorre i was thinking it change himself

@AnneRanch All I can say is if you try something like: // assume array has >= 3 elements for (int index = 0; index < 3; index++) connect(subMenu_checkableActionInMenu[index], &QAction::triggered, this, [=]() { qDebug() << index; } ); I would expect you to see 0/1/2 according as which one you click on. You might like to test that.
