@DerReisende Goodness knows :) I'm wedded to VirtualBox coz I just about know how to use it. I did "ESXi", that's VMware isn't it, and found it a nightmare to manage! I will have a look tomorrow at graphics settings, normally I don't think about them, didn't occur to me as I'm only writing to a window title, but who knows. About the only UI that was 100.00% reliable was a VT220, ever since windowing systems there have always been problems....

@8Observer8 Good to know. Thanks. Actually, I wanted to ask you if you tried it. m_pStartGameButton->winId(); // add this <<=========this is the tricky part.

@JonB The input bitmap is my own format which contains (effectively) three vectors of type <T> in this case uint16_t, so incrementing pRed will move to the next uint16_t in the red channel. At least that's the theory! In practice it turns out there was a problem when converting a 16 bit QImage into the local representation that resulted in the local bitmap being corrupt! So the code I posted may even be correct!!! David

There is no difference, sliced() was only added because "This keeps the API symmetric with what we have in our string classes.": https://codereview.qt-project.org/c/qt/qtbase/+/305959

@JonB Thanks for the link! I learned that std::auto_ptr is removed in c++17. So I checked the upstream repo of my submodule and they really have a commit fixing that issue. Updating the submodule fixed my issue. Thanks again!

@JonB Yes this works for me, thanks.

Hi, I remember that I had a project to send fake mail to others without any mail server, unfortunately, I have not codes, but you can use this conception by using some mail server's adventures. good luck.

@Abderrahmene_Rayene Ha! I knew it would be something as simple as that...

https://code.qt.io/cgit/qt-creator/qt-creator.git/ . Build details are in https://github.com/qt-creator/qt-creator#readme .

@victor_wen Great. Feel free to 'resolve' this topic then.

@JonB much appreciate your directions，I'll give it a try.

@Mark81 While inside a Linux signal handler, such as from SIGINT/SIGTERM, you are very limited as to what you are allowed to do "safely". Basically you are in a context where you are supposed to do as little as possible (e.g. set a variable) and then exit the signal handler. You are not supposed to do anything at all "complicated". So, for example, using Qt I think it would be best to post a simple message/signal --- assuming that is safe --- and exit the signal handler, allowing the event loop to later pick that up and do the actual exiting, rather than doing the exit from within the signal handler directly. In your connect() above, for example, I would be making it a Qt::QueuedConnection. (For other reasons the code at https://doc.qt.io/qt-6/qcoreapplication.html#quit actually recommends/shows this anyway.)

Yes, it is possible. How to approach this depends on what you want to achieve. The translator can load any .qm file you give him. It does not matter if it is located in your resources (i.e. embedded into the .exe) or if it is an individual file on disk. If you want the possibility to add many more languages or give the user the ability to do their own translations, you can generate a dummy .ts file. Everyone can just change the language right at the top of this .ts file before opening it with Qt Linguist. So, you don't really need to generate multiple .ts files from source code, but can just copy an existing .ts file (most useful if there are no translations in it) and change the language. You could provide this .ts file without any translations to your users. Then, you can have two different methods how to apply additional translations. One suggestion was already to do this through the locale. However, you can also provide an option to load a specific translation file by filename. Then, it does not actually matter which language is set in the translation file. If users should be able to do their own translations, I'd prefer to select additional languages by filename. This is easier to explain.

@SGaist Ok I opened CmakeList.txt and it's ok. Thank you very much

Hi @AnneRanch I like to colorize parts (text) of the QDebug output. Here's how I do it in one of my open-source projects: #if defined(Q_OS_UNIX) #include <unistd.h> #elif defined(Q_OS_WIN) #include <Windows.h> #endif inline bool haveConsole() { #if defined(Q_OS_UNIX) return isatty(STDERR_FILENO); #elif defined(Q_OS_WIN) return GetConsoleWindow(); #else return false; #endif } void configureLogging(const QCommandLineParser &parser) { // Start with the Qt default message pattern (see qtbase:::qlogging.cpp:defaultPattern) QString messagePattern = QStringLiteral("%{if-category}%{category}: %{endif}%{message}"); if (parser.isSet(QStringLiteral("debug"))) { #ifdef QT_MESSAGELOGCONTEXT // %{file}, %{line} and %{function} are only available when QT_MESSAGELOGCONTEXT is set. messagePattern.prepend(QStringLiteral("%{function} ")); #endif messagePattern.prepend(QStringLiteral("%{time process} %{threadid} %{type} ")); } const QString color = parser.value(QStringLiteral("color")); if ((color == QStringLiteral("yes")) || (color == QStringLiteral("auto") && haveConsole())) { messagePattern.prepend(QStringLiteral( "%{if-debug}\x1b[37m%{endif}" // White "%{if-info}\x1b[32m%{endif}" // Green "%{if-warning}\x1b[35m%{endif}" // Magenta "%{if-critical}\x1b[31m%{endif}" // Red "%{if-fatal}\x1b[31;1m%{endif}")); // Red and bold messagePattern.append(QStringLiteral("\x1b[0m")); // Reset. } qSetMessagePattern(messagePattern); } Cheers.

what are they, Build folders. and what makes them , The compiler. and why Because something was compiled. ?? Why two question marks? Does it mean, you’ll ask the question again in a while? Or was the question mark forgotten the first time? I am confused.

Hi, QStackedWidget comes to mind for that. Put your labels in it and the buttons underneath.

@lukutis222 AFAIK, pre-built binaries for that module are available for commercial license holder. As for Qt Creator, most likely because Qt Creator is way younger than Qt itself and has likely not yet been used as much as other means to develop Qt. Note that having for example the qtbase completely loaded in an IDE is a pretty intensive task which might not even be doable due to the sheer size of the module. However, additional documentation on that matter would be something good.
