@eschmo said in Problem connecting Signals and Slots in a modal dialog: I've removed it completely and everything is fine now! I'm afraid that credit goes to @mrjj ;) Sorry, not sure why this was in the files i've uploaded but this was allready changed yesterday. I'm talking header, not cpp [image: 6a5cfb98-2e73-4132-986f-84fdf14301f6.png]

@ailika said in How to use QTableWidget::setCellWidget() to set a widget such as a QComboBox and do the further handling?: the object is generated in the function which means that it will delete when the function end, am I right? Nope, it's allocated on the heap so it will live untill someone calls delete on it If it is this way, there will not be too much consumption by creating combox. No, this is the method chosen by the Qt architects to save on resources If I use openPersistentEditor, the combox will always preserve, I presume? Yes but you will have the same performance issues you would have with setIndexWidget

@Alok-Sinha Are you clicking it right ? [image: F3K1NI.png]

@Meera-Hadid You can do something like emitting signals on your own see more: https://doc.qt.io/qt-5/signalsandslots.html Create a slot , as you said update() What causes the button text to change emit signal there , and it will execute things in slot As others have said , a basic example is required for what you want

Thanks for your answers. So the best way to custom a combobox color is to edit StyleSheet Properties and manually make the combobox looks like Windows 10 apparence with a different color ?

@SPlatten If others didn't work then try using QMap QMap<QString,QString> icons; // first one for text or item no and second for path icons.insert("first selection", ":/ICN_CONNTD"); icons.insert("second selection", ":/SECOND"); // and on selection change you can simply get the icon using selectionChanged(QString text){ QString iconName = icons.value(text); // Here you can access the icon name } I don't think as good answer but it can get work done. LOL Thanks

@stretchthebits Which version of QT are you using ? Did you update or install the offline version of QT?

@Qt-embedded-developer Here the answers can take minutes, days, months or never but that does not imply that you abuse the system. You must be patient, show your research, make your post attractive. If you check you will see that the posts that show information are more likely to get a response. This post does not provide any but the other post has done so obtaining more feedback. I hope that some moderator takes action on the matter.

@Qt-embedded-developer [image: 2e756263-5c4b-425a-980f-636c9f8ccca2.png] this->ui.horizontalLayout->setStretch(0, 10); this->ui.horizontalLayout->setStretch(1, 300); this->ui.horizontalLayout->setStretch(2, 10); I changed it to a horizontal layout, but the middle is not aligned. The qt alignment is also centered.

@SGaist I tried to use COPY_FILE_NO_BUFFERING, but I had the same problem.

@ChrisW67 Ok I understood... Thank you.

@Qt-embedded-developer Have you tried compiling? Have you had problems doing it?

So what was the final solution@V0rtex Is it just a compiler switch？

@IknowQT Sometimes it happens that for efficiency reasons Qt does not update some properties and it does so when the widgets are just displayed. And it seems that this is the case.

@SGaist I was too sure I guess... :-) Thanks!

Hi, What is the stack trace of your crash ? Nothing stands out as really wrong from the example you linked except the understanding of the lifetime requirements for the QFile.

@ChrisW67 I got it working with QMAKE_CFLAG setting to c11 Not sure what I compiles fine in some distro without this, but at least this is the solution for others
