OoI, why did Qt6 QString feel the need to introduce sliced() when we have had mid() for years?
EDIT Oh, mid() docs now say

If you know that position and n cannot be out of bounds, use sliced() instead in new code, because it is faster.

@ekkescorner Assam Boudjelthia has done a great work on this and now prepared cherry-picks for 5.15 🙂
see QTBUG-98974
can someone help and test ?

Hello, I want to know how to add a suffix to a file after saving it on filedialog in qml and I came here in hope to find my answer. But It makes me sad when I can't find it. I tried filePath = filePath + '.txt' but isn't working for me. Can anyone share a website with me in which I can find the solution? I will be very much thankful to you.

it worked. thanks @VRonin

@JonB Thanks a lot. Solved it by this:
outstream<<line<<'\n'; :)

@Christian-Ehrlicher No, and I asked you to check the original question rather than the latest update, which you seem to have trouble understanding without the original context. So here's the quote from the original question for you:

When I run this [code in question] under GNU/Linux the output hash is the same as a result of running command line tool md5 or md5sum. When I run the very same code under MacOS - I get different hashes from the application and command line.

I never wrote I was trying to compare hashes between two different OSes (and files for that matter). The mismatch was between hash given by the Qt code I quoted and the regular command line tool hashing a file on the same OS.

@suslucoder said in Double Spin Box Save to the file:

Is it possible to do it?

Is it possible to do what?

The fact that you divide your UI so that the data is presented on separate tabs/pages (which is fine) has nothing to do with whether it is possible to save data, nor whether you might adopt a QDataWidgetMapper approach.

@suslucoder As the error message tells you addSeries takes a QAbstractSeries, not a string list as parameter. You have to pass it one of the QAreaSeries, QBoxPlotSeries, QCandlestickSeries, QPieSeries, and QXYSeries.
You also should tell us what data your file actually contains? If it contains x/y values then you first have to convert the data to numbers and create a QXYSeries instance and fill it with that data (https://doc.qt.io/qt-5/qxyseries.html#append).

Okey thank u

I think you can bundle lupdate in your application and create qm file on the fly.

P.S. : TS files are just xml files, so you can change them in your own application, via user feedback or something else

@artwaw Yes, it works fine eventually :)

@JonB Oh yeah sorry.. I wasn't reading the right. It was opening in a VS text editor. I tried running it with notepad and it worked. I guess VS has something where they keep the file open, so i couldn't edit it and then update the display.

@shokarta try with Android FileDialog

FileDialog { title: qsTr("Select a File") fileMode: FileDialog.OpenFile onAccepted: { if(selectedFiles.length) { console.log("we selected: ", selectedFiles[0])

Selected File 'München.pdf' from FileDialog
...this gives you per ex:

content://com.android.providers.downloads.documents/document/32

// you can check from C++ and verify fileUrl:

QFileInfo fileInfo(fileUrl); qDebug() << "verifying fileUrl: " << fileUrl; qDebug() << "BASE: " << fileInfo.baseName(); qDebug() << "FileName: " << fileInfo.fileName(); qDebug() << "Path: " << fileInfo.path(); qDebug() << "absoluteFilePath: " << fileInfo.absoluteFilePath(); return fileInfo.exists();

this gives you:

verifying fileUrl: "content://com.android.providers.downloads.documents/document/32" BASE: "München" FileName: "München.pdf" Path: "content://com.android.providers.downloads.documents/document" absoluteFilePath: "content://com.android.providers.downloads.documents/document/32" file exists

@J.Hilk Thanks for your answer. But I want to ask how can I know I have to choose one over the another?

After running the application "Bluetooth File Transfer" I faced the following error:

Thanks in advance!

Take a look at the QSettings class here

Just had the chance to test. Thanx a lot

#include <QCoreApplication> #include <QNetworkAccessManager> #include <QNetworkReply> #include <QNetworkRequest> int main(int argc, char *argv[]) { QCoreApplication a(argc,argv); QNetworkAccessManager netMan; QNetworkReply* const repl = netMan.get(QNetworkRequest(QUrl::fromUserInput(R"**(ftp://131.225.104.13/linux/.snapshot/NDMP_AUTO_SNAPSHOT3210/fermi/contrib/obsolete/video/nvidia/5328/NVIDIA.5328.README.txt)**"))); QObject::connect(repl,&QNetworkReply::readyRead,[repl]()->void{ qDebug().noquote() << repl->readAll(); }); QObject::connect(repl,QOverload<QNetworkReply::NetworkError>::of(&QNetworkReply::error),[repl]()->void{ qDebug() << "Error: " + repl->errorString(); }); QObject::connect(repl,&QNetworkReply::finished,repl,&QNetworkReply::deleteLater); QObject::connect(&netMan,&QNetworkAccessManager::authenticationRequired,repl,[repl](QNetworkReply *reply, QAuthenticator *authenticator)->void{ if(reply!=repl) return; aAuthenticator->setUser("MyUserName"); aAuthenticator->setPassword("MyPassword"); }); return a.exec(); }

@Qjay
This may not help because I do not know quite how you would do this directly from Qt, but when we want to print a PDF under Windows we use the underlying Win32 function ShellExecute() (https://msdn.microsoft.com/en-us/library/windows/desktop/bb762153(v=vs.85).aspx) to go (effectively) ShellExecute("print", native-path-to-file), and let Windows shell sort it out.

This is effectively the same as right-clicking on the file and picking the Print action. So you don't need to know anything about the actual process which does the printing, its arguments etc.

@koahnig Thanx mate
