General and Desktop

Thank you for your answers.

@jsulm No difference, unfortunately. That is acutally the reason why I use os.path.join in order to get backslashes for Windows an forwardslashes for Mac/Linux. And as I said, the path with backslashes works in Windows Explorer. Maybe it has to do with any QFrame properties (shape, style...) which have to be set in Windows to show background-images? I will try a bit...

@SimonSchroeder OKay thanks.We shall see when he explain more

Do you resolve this issue? I use vcpkg install qt:x64-windows-static,and found in release mode ,the ${Qt_LIBS_} is include some debug librarys,such as qwindowsvistastyled.lib, qwindowsd.lib, ets I think this is an error from Qt Tools, but i can't modify it.

@JonB Thanks JonB it's work now !!! I'am a very bad programmer ;) QFile file(QString(QApplication::applicationDirPath() + "/STMartin/Traitement/Traitement et contention.csv")); if(!file.open(QIODevice::ReadOnly | QIODevice::Text)) { QMessageBox::critical(this, tr("Je ne trouve pas le fichier "), tr("")); return; } int numeroDeLaligneAnalysee = -1; int numeroDuResident = -1; while (!file.atEnd()) { const QString ligneEnCourDeLecture = QString::fromLatin1(file.readLine()); QString ligneATravailler = ligneEnCourDeLecture; QStringList denominationDeChaqueResident; numeroDeLaligneAnalysee++; denominationDeChaqueResident.append(QString::number(numeroDeLaligneAnalysee) + ";"); if(ligneEnCourDeLecture.left(4) == "Mme." || ligneEnCourDeLecture.left(2) == "M.") { numeroDuResident++; denominationDeChaqueResident.append(QString::number(numeroDuResident) + ";"); if(ligneEnCourDeLecture.contains("(F)")) { ligneATravailler = ligneEnCourDeLecture.left(ligneEnCourDeLecture.indexOf("(F)")); } if(ligneEnCourDeLecture.contains("(H)")) { ligneATravailler = ligneEnCourDeLecture.left(ligneEnCourDeLecture.indexOf("(H)")); } if(ligneEnCourDeLecture.contains("née")) { ligneATravailler = ligneEnCourDeLecture.left(ligneEnCourDeLecture.indexOf("née")); } while(ligneATravailler.contains(",")) ligneATravailler.remove(","); while(ligneATravailler.contains("-")) ligneATravailler.remove("-"); ligneATravailler = ligneATravailler.simplified(); ligneATravailler = ligneATravailler.trimmed(); QStringList civiliteNomEtPrenom = ligneATravailler.split(" "); QString civilite; if(civiliteNomEtPrenom.at(0) == "Mme.") { civilite = "F"; civiliteNomEtPrenom.takeFirst(); } if(civiliteNomEtPrenom.at(0) == "M.") { civilite = "H"; civiliteNomEtPrenom.takeFirst(); } denominationDeChaqueResident.append(civilite + ";"); QString listNom; QString listPrenom; for (int i = 0 ; i < civiliteNomEtPrenom.size() ; i++) { QRegularExpression nom("[A-Z][A-ZÉ\s]"); QRegularExpressionMatch matchNom = nom.match(civiliteNomEtPrenom.at(i)); if (matchNom.hasMatch()) { listNom.append(civiliteNomEtPrenom.takeAt(i)); } QRegularExpression prenom("^[A-Z][a-z]*$"); QRegularExpressionMatch matchPrenom = prenom.match(civiliteNomEtPrenom.at(i)); if (matchPrenom.hasMatch()) { listPrenom.append(civiliteNomEtPrenom.takeAt(i)); } } if(!civiliteNomEtPrenom.isEmpty()) { QMessageBox::critical(this, tr("civiliteNomEtPrenom n est pas vide. Il reste cela"), civiliteNomEtPrenom.first()); return; } denominationDeChaqueResident.append(listNom + ";"); denominationDeChaqueResident.append(listPrenom + ";"); qDebug()<< "denominationDeChaqueResident" << denominationDeChaqueResident; } }

@loren Also remember you have to properly code sign your application if you want to distribute to other people. On intel macs it is not as bad as on Apple Silicon machines - these will not execute your program and you will find crash reports with SIGSEGV and code signature invalid on the machine using the console app.

@Vlad02 Maybe it will be useful for someone: in general, I decided to just replace drawing a polygon with drawing a set of lines, so I get symmetrical arrows. Thank you all for your help!

@JonB thx for help

@Ronel_qtmaster oh i understood what i wasn't getting yeah idk why i did that, thanks! onto the next mistake....

@GrecKo That is, I would instantiate a Scale object, and reparent the original component? And hope the component doesn't depend on a specific parent hierarchy to work.

@LinuxGuy I think it is not easy to see the mouse outside of your application windows. Might have to "grab" the mouse, which is not pretty and can leave window system unstable, might be able to "poll" on a timer (https://stackoverflow.com/a/29400627/489865). Google for qt mouse outside application. Then there is the complication that the windowing system is in the middle of a window-drag operation, which can only make it harder, and you want to detect drop as well. And if you are using Wayland wouldn't surprise me if it stops you doing this (I have no evidence for this, just that it sounds like what it would want to prevent). Can you name an application, other than something in the window manager itself, which does what you are wanting to do?

If your menu have actions & you want to add tool-tip for the respective actions , can follow these steps: 1: set tool-tip (action.settooltip("Your tool tip")) for every action. 2: write a connect statement on hovered() signal and write a slot for it. 3: in slot definition you have to write QAction* act = static_cast<QAction*>(QObject::sender()); QToolTip::showText(QCursor::pos(),act->toolTip(),menuObject_where you have added action);

@SeyMohsenFls As stated, you have to rewrite the complete file, can't be clearer. You have two possible ways: Read whole file into memory, in some structure (even if it's just a list of lines). Make modifications to it in memory. Write whole file back when completed, e.g. overwriting original file. This is how e.g. a text editor or sort works. Open existing file for read, open a new file for write. As you read each line in, make any modifications and write new line out. At the end probably/perhaps delete original file and rename new file to that. This is how e.g. sed works. Either way you completely rewrite new file. Difference is how much memory you use.

@Mesrine said in Qt cmake deployment API and Cpack not working for macos: Unspecified That was the problem. It seems that install(TARGETS QVaultCli BUNDLE DESTINATION . RUNTIME DESTINATION ${CMAKE_INSTALL_BINDIR} COMPONENT vaultCli ) Do not add the bundle to the cpack vaultCli component.

@SimonSchroeder See the discussion around https://forum.qt.io/topic/155461/qlineedit-returnpressed-when-something-else-has-a-key_return-shortcut/16 for the pointlessness/potential evilness of the NumPad Enter key ;-)

@SGaist yes
