General and Desktop

Qt 5.11.2 on Windows. The data comes from a custom variant type. I can't really make a minimal example, unless I strip out my custom types. If I can't figure it out soon I'll try to make an example that duplicates the issue. I did notice that if I set all column's TextAlignmentRole to Qt::AlignRight that the text of the second and third columns disappears off the right side of the column when the table is expanded horizontally, which leads me to believe that there's a discrepancy between the size that's actually visible, and the size that's being used to render/position the text. In the table's resizeEvent() method I have: setColumnWidth(0, width() / 3); setColumnWidth(1, width() / 3); setColumnWidth(2, width() / 3); Which is the only thing I can think of that would be affecting this.

You would likely have to fiddle with the backend code.

Hi, That's not really clear. Can you show the code you are using ? Maybe a picture of what you are expecting VS what you are getting ?

@Christian-Ehrlicher said in Parsing large/big text files (quickly): or maybe even iterate over line with QByteArray::indexOf(' ', oldIdx) // edit: fixed the split to split by space instead \n, thx @mrjj Thank you, I am now using QByteArray::indexOf and what I used to do before in about 2 minutes, now takes about 17 seconds.. thanks again !

Hi, At your own risk but you can enable the use of private APIs. For example QT += gui-private.

Yes, it's per QNAM object.

Solved! :) The problem was with Windows firewall which prevented the Gradle to download things. I disabled both firewall and antivirus temporarily and tested the program once again. It was for a few minutes just showing lines: download http/ ...... Then it succeeded to show the app on the tablet. :) Then I enabled both firewall and antivirus and tested that and also other programs. No download anymore. It seems that only one time it's required. All apps are shown on the device. :) There's only few tiny red lines (apart from warnings) that make me rather worry. Here's the bottom section of the Output window: [image: 37e229d0-b050-4c08-89d1-3e95643afa91.PNG] Do you have any idea what they are and should they be solved too?

@Au7h please don't forget to mark your post as solved. Thanks.

Hi, I think you might be interested by QTextDocumentWriter. Sorry, I misread ODT for ODF.

I found a solution. Please see my stackoverflow post.

Hi, You didn't follow the guide properly. It says make sub-mysql. The way you did it, you are currently trying to build all the plugins which is not what you're after.

Is already reported: https://bugreports.qt.io/browse/QTBUG-72463

The Jenkins instance is hosted on a different server and is currently connected to several linux slaves that build properly. It's just the macos slave that has the issue. It seems to be slow in both qmake and make steps. We just found a solution that requires us to switch the user to itself before running the command. sudo -u <loggedinuser> -i bash /script/containging/build/commands.sh I'm not sure why this has to be done since we are already logged in as the user that we are switching to. My guess is that Apple enables certain restrictions for remote users.

The bug will be fixed in 5.12.1

@mrjj That sounds exactly like what I would like to do, is it possible for you to supply me with some more information on how I could approach this? possibly some pseudo-code or bullet points? What variables would you recommend storing in the controller class and how would you recommend it communicates with the rest of the classes?

@mrjj Worked perfectly with ultravnc thank you very much.

Hi @kripashree , to open a file use QFile. Following the example on the page MainWindow::onButtonClicked() { QFile file("in.csv"); if (!file.open(QIODevice::ReadOnly | QIODevice::Text)) return; while (!file.atEnd()) { QByteArray line = file.readLine(); QList<QByteArray> values = line.split(";"); // depending on your sperator in the csv file // do whatever you want with the values } } The onButtonClicked() function needs to be connected with a signal of your button. In general this connection is set in the constructor of your main window class. Eg: MainWindow::MainWindow() { connect(buttonPointer, &QPushButton::clicked, this, &MainWindow::onButtonClicked); }

C++ basics are needed before you start Qt. void myFunc(QLineEdit *lineEditObject) { LineEditObject->settext("some text"); }
