Hi, Is this the Qt version that comes with your distribution ? If not, can you try that one ? Did you also check with a more recent version ? 6.9 was released no too long ago.

Did you try to restart your machine once between two runs to check if it still comes up ?

@Don-Burner said in Throwing from QFuture::onFailed(): I use std::set_terminate, so unhandled exceptions call my terminate handler. EDIT: I thought std::terminate() always called std::abort(). Turns out, it calls the current terminate handler. In short, calling std::terminate() within QFuture::onFailed() works, at least for my purposes. Thanks!

Just in case, the systray example from Qt's documentation works as expected on macOS so it I think it would be good to compare the two code bases to see what is being done differently. The MacOSSysTray implementation takes quite a lot of detours to achieve the same outcome as the systray example. So I would suggest to simplify things there.

@jeremy_k I appreciate it. I successfully implemented that feature.

@Christian-Ehrlicher said in Remove default file association: You can't do this with Qt as it's to OS-specific. You are certainly right about the first part. However, I would claim that this is something (at least up to a certain point) that could actually fall into the realm of Qt. All operating systems have some sort of file type association. Windows and macOS should be pretty straight forward. I am not entirely sure about Linux if this is related to the window manager. There is certainly a certain standard with xdgutils. But, I believe this is mostly for the command line and not used by every window manager. A lot of people would already be covered by supporting Gnome and KDE (maybe another 1 or 2 window managers). What I'm saying is that it is not too crazy to expect this to be part of Qt. QSettings properly stores configuration according to common platform rules (even uses the registry on Windows).

@sirspot Hi and welcome to devnet, Please provide a complete minimal compilable example that shows this behavior.

Sorry, I've misunderstood your goal. So QCoreApplication::applicationDirPath is the simple way to do it.

Super, thanks!

Nice ! Don't forget to mark the thread as solved :-)

ok, thanks, your solutions work and I'm able to get the xcb connection. And I'm able to use xcb_change_window_attributes() (with above code using XCB_CW_EVENT_MASK) to turn on/off receiving native events for a Window (for example XCB_FOCUS_IN), but except the XCB_VISIBILITY_NOTIFY event. I just can not receive this event. is it related to something changed in Qt6?

@Christian-Ehrlicher Thank you, Christian, it worked.

@Pl45m4 I want the leftmost and middle layouts to keep the minimum size, and the rightmost to fill all the remaining space. Now I changed it to (1, 4, 10), the display effect is fine, but I think the effect of (0,0,1) is weird.

Suggestion duly noted. Since the widget(s) the code was adding and removing was the first QWidget I ever wrote, it definitely needs revisiting.

Hi about this topic there are many request, a additional tickets are: https://bugreports.qt.io/browse/QTBUG-67161 https://bugreports.qt.io/browse/QTBUG-134694 In the version of Qt 6.9.1 I found that: 10e546f015e QNetworkAccessManager: don't resend non-idempotent requests Non-idempotent requests are no longer incorrectly re-sent if the connection breaks down while reading the response. Codereview: https://codereview.qt-project.org/c/qt/qtbase/+/633298 After many year is it fixed !!! is time to forgot Curl for rest request? :-)

@Christian-Ehrlicher said in QTreeView::sortByColumn(int column, Qt::SortOrder order) Why does this function sort not by numbers but by characters: @Seb-Tur Don't add the values as QString but as numbers. -> QStandardItem::setData(value, Qt::DisplayRole) Yes, thank you. This gets the job done. AI and the above people came up with crazy stuff.

@JonB said in Concept for analyze several XML messages, sometimes incomplete.: What exactly do you mean by this? I send and receive XML messages via socket, which I have to evaluate. There may be 0000 between the messages, other characters that are not necessary for XML. Presumably buffer with 000 The idea is to read <Root> XXXXXX </Root>. It may be that two messages come at once, too fast. How can I solve this? RingBuffer? Do you have a good example of how to solve this?

If anyone comes across this, you can also achieve this by changing X11's WM_CLIENT_MACHINE property of your widget. Gnome will treat this as a different application. You can also see how gnome matches windows to applications here: https://github.com/GNOME/gnome-shell/blob/main/src/shell-window-tracker.c#L388.
