@m4t1 Did you try export LD_LIBRARY_PATH=HERE_PATH_TO_QT_LIBS_DIR && ./my_app ?

It is solved - I had to find some updates for external libraries and the problem was gone.

@SGaist mmh 🤔 right, May be a better approach, than what I currently have. I'll have to test it. Thanks!

Dupe of https://bugreports.qt.io/browse/QTBUG-13522 - don't use widgets in itemviews. We really should have deprecate this widget inside item views stuff in Qt6...

@canid as per qt doc.. On Windows, for 32-bit programs running in WOW64 mode, settings are stored in the following registry path: HKEY_LOCAL_MACHINE\Software\WOW6432node I feel 32 bit & 64 bit application registry locations are different..

@georgiav said in Running qt on external computer: Can I run my program on an external computer that doesn't have qt? Yes you can. Just deploy your application: https://doc.qt.io/qt-5/deployment.html for the open source version of qt, the application built can be run only within Qt , right? Nope, for 2 different reasons: The whole purpose of free and open-source software is to guarantee freedoms to users. So, you have the freedom to run the application anywhere you want. You're thinking about running the application within Qt Creator, the IDE (Integrated Development Environment). Qt is a library. Qt is not Qt Creator.

Thanks @SGaist @eyllanesc. Yes I am using a TableView to display the table of data and QFormLayout and QDataWidgetMapper to update, delete and insert records. I am passing configuration parameters to format column titles with friendlier text and format numbers and texts like @eyllanesc showed. As my app will have several different tables I just thought that a reimplementation of QSqlTableModel could be a one stop shop for everything and got stuck with the delete record. Thanks guys!

Hi Did you try https://doc.qt.io/qt-5/qml-qtquick-controls-splitview.html#details

That's the way I'd like to go. Unfortunately I can't use a Tool interface, as the only commonality between tools is that they emit a windowClosed() event; that means the interface will need to inherit QObject, and if a tool inherits QMainWindow, as it most certainly will, that will lead to multiple inheritance. But I can't be certain that a tool will inherit QMainWindow, so I'd like to avoid creating an abstract base class inheriting QMainWindow. With this in mind, I think the windowClosed() event should be renamed to something more generic, such as toolClosed(). Anyway, I think if a tool has a QMainWindow, or another widget, instead of inheriting from it, it will solve the problem with the inheritance. I'll try that and come back if I still can't figure it out. Thanks for the suggestion!

Thanks, @Christian-Ehrlicher. I wasn't aware of this function, I am going to try to remove all unknown arguments before running parse() and avoid having to ignore a return value on dubious purpose.

Yes, it was a custom widget in title bar. I wasn't able to figure out where this is coming from so I went with a different solution but still strange behavior.

@jbbb said in How to extract variable created in the function to the variable outside of the function?: any example? Take a c++ book, read about classes. Nothing Qt-specific here, simple c++ basics. Sorry.

Thanks it works!

@Christian-Ehrlicher, it work well now as expected after i created my own dialog inherit QDialog and used setStyleSheet for the whole personal dialog. thank you for your help.
