@ThirdStrand I see "Qt MQTT" in my installer (so under commercial license) for Qt 6 - it is under "Additional Libraries". So either it is missing from Open Souce installer (which would be weird) or maybe you are looking at Qt 5?

@yygk said in Configuring Qt5.15.2 for Linux '-no-xinput2' error?: ERROR: Unknown command line option '-no-xinput2'. This means that this configure option is not available - see configure --help to find out which options it provides.

@SGaist Yes, if the doc snippet is copypasted, and everything else is commented out, - same issue. I'll try on new project, maybe got any new ideas.

@MayEnjoy Did you try a lower version or a higher version to see if the issue is fixed?

I ended up leaving out EGLFS_DEVICE_INTEGRATION from the mkspec and compiling as-is, works fine.

@Damian7546 We don't know since we don't know what this->GetCRC16(buffer, buffer.size()) does or returns. If I had to guess, I would say this is not right. If you are passing buffer, buffer.size() to GetCRC16() what does that do in buffer and why would you want to append the result to CRC if you have already called something which perhaps/at a guess already appends there? [Actually, it may be correct, provided GetCRC16() reads buffer.size() bytes from buffer and returns a new QByteArray, does not write into buffer.]

@AnneRanch said in Qt Regular expresssion example - how to use it?: QRegularExpression expressions for multiple matches DOES NOT WORK As answered in your https://forum.qt.io/topic/152003/how-to-retrieve-match-at-least-next-pair-regular-expression, for your case you must use QRegularExpression::globalMatch() instead of QRegularExpression::match(). That is what you are looking for in your case. Like the following: QRegularExpression re("hci[0-9]+\t[0-9A-F:]+"); QRegularExpressionMatchIterator i = re.globalMatch(yourVariableOfTheInputString); while (i.hasNext()) { QRegularExpressionMatch match = i.next(); qDebug() << match.captured(); } So from your input string in that other post, complete program: #include <QCoreApplication> #include <QDebug> #include <QRegularExpression> int main(int argc, char *argv[]) { QCoreApplication a(argc, argv); QString input ( "Devices:\n\thci8\t00:50:B6:80:4D:5D\n\thci0\t00:15:83:15:A2:CB\n" \ "Devices:\n\thci8\t00:50:B6:80:4D:5D\n\thci0\t00:15:83:15:A2:CB\n" \ " SUCCESS test_contains Devices:Devices:\n\thci8\t00:50:B6:80:4D:5D\n\thci0\t00:15:83:15:A2:CB\n DEBUG TASK START Bluetooth " \ " MATCH result " \ "hci8\t00:50:B6:80:4D:5D" \ " MATCH result " \ " SCAN results hci8\t00:50:B6:80:4D:5D" ); QRegularExpression re("hci[0-9]+\t[0-9A-F:]+"); QRegularExpressionMatchIterator i = re.globalMatch(input); while (i.hasNext()) { QRegularExpressionMatch match = i.next(); qDebug() << match.captured(); } return a.exec(); } produces output "hci8\t00:50:B6:80:4D:5D" "hci0\t00:15:83:15:A2:CB" "hci8\t00:50:B6:80:4D:5D" "hci0\t00:15:83:15:A2:CB" "hci8\t00:50:B6:80:4D:5D" "hci0\t00:15:83:15:A2:CB" "hci8\t00:50:B6:80:4D:5D" "hci8\t00:50:B6:80:4D:5D" which is just what you wanted, right?

i think it may be effect for me。the question can close now。if has problem, i will ask again。thanks for all of you。

@kapabahwuk tesseract3.02.02.dll and llept.dll can you share? 1721849726@qq.com Thank you

@Chris-Kawa Thank you very much , this is what i needed.

@mitchSyd said in Dialog issues on macOS: can you tell me if there is an upgrade Without any code others can only guess what you are doing...

The problem was solved after I reinstalled Qt 6.6.0. However, I am still unsure of what caused the issue in the first place. Thank You @Christian-Ehrlicher

@apalomer said in Use qt installer framework in a windows docker container: I have solved the issue myself. Although I do not understand why, everything works if I use FROM mcr.microsoft.com/windows:20H2 instead of FROM mcr.microsoft.com/dotnet/framework/runtime:4.8-windowsservercore-ltsc2019. I tried that but got this error: (8007052E The user name or password is incorrect)

I couldn't find a solution, but as a workaround I used QProcess running wl-copy

@jsulm Where? Here: I had written C-style casts are forbidden where I come from! :-) he wrote away to jail with you than!(sic) int y = (int)x; and int y = int(x); are functionally the same in C++ I had not written "anything functionally the same as a C-style cast is forbidden" [which would forbid all named casts, so I'm unlikely to say that.] The "away to jail" jibe makes sense only if it is asserting that int(x) isa C-style cast. Enough.

@SPlatten said in QMenuBar, QMenu and QAction: pobjMenu->show(); pobjMenuBar->show(); Still weird that this seems to fix it because usually you dont have to show a QMenuBar explicitly. Or what fixed it in the end? QMainWindow::menuBar() says: Returns the menu bar for the main window. This function creates and returns an empty menu bar if the menu bar does not exist. And this, either existing QMenuBar or the newly created one, is already a child of QMainWindow. So I wouldn't expect that you have to show it or apply it to your mainWindow manually again. Dont know if this is somewhat relevant for you but reading the documentation further, it says: If you want all windows in a Mac application to share one menu bar, don't use this function to create it, because the menu bar created here will have this QMainWindow as its parent. Instead, you must create a menu bar that does not have a parent, which you can then share among all the Mac windows. Create a parent-less menu bar this way: QMenuBar *menuBar = new QMenuBar(0);

@roditu add this in your code for debugging. Then you may know why the size is so big. ScrollBar.vertical: ScrollBar { id: vscrollBar } Component.onCompleted: { console.log( "size = ",vscrollBar.size ) }

@gfxx for bool var only solution seems easy ... retval = UA_Server_readValue(this->m_server, this->m_StopCiclo, &val2); if((retval == UA_STATUSCODE_GOOD) && (val2.type == &UA_TYPES[UA_TYPES_BOOLEAN])) {Stop_bv = (((UA_Boolean*)val2.data)[0]); Stop = Stop_bv; } where Stop_bv and is bool var used for manipulate gui .... Stop is bool var used for write server node;

May be you can try this(Windows port) freedesktop.org
