QTableView sort indicator not shows

I'd also put in a

hh->setSortIndicator(3, Qt::AscendingOrder);

before the last setSortIndicatorShown().

Still not work

MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent), ui(new Ui::MainWindow)
{
    ui->setupUi(this);

    QHeaderView * hh = ui->tableView_evaluator->horizontalHeader();

    hh->setSortIndicatorShown(true);

    ui->tableView_evaluator->setModel(&tableModel_evaluator);

    hh->setSortIndicatorShown(true);

    ui->tableView_evaluator->setSortingEnabled(true);
    bool b = ui->tableView_evaluator->isSortingEnabled();
    Q_ASSERT(b);

//    ui->tableView_evaluator->sortByColumn(3, Qt::AscendingOrder);

    hh->setSortIndicator(3, Qt::AscendingOrder);

    hh->setSortIndicatorShown(true);
}

Humour me: I see your Q_ASSERT() (you aren't compiling for no-debug, are you?), but try putting in an explicit ui->tableView_evaluator->setSortingEnabled(true).

Compiling in debug mode, I've set it to true in UI designer.

Don't know then. https://stackoverflow.com/questions/43535789/how-to-set-sort-indicator-for-qtableview-programatically reports the same as you, but was never answered if the indicators truly do not show for that user. It shows the principle of what you're supposed to write. There seem to be plenty of others for whom indicators are working fine. You're not using any special "skin"/"theme" on your platform (which is what?)? Or some table style or something which might not show the indicators?

P.S.
Last thing: try a setSectionsClickable(true), just in case that influences...?

No, a demo simply for testing.

Tried, failed.

OK. At this point: I can't help because I'm not C++, but:

• Can you produce a 20-liner minimal (2 data rows) complete which compiles? So someone can just paste and try.
• Tell us what version of Qt and what platform.
• Request someone kind who fancies compiling. @mrjj is known to be very helpful at trying other people's UI stuff. :) :)
• Compare their result to yours.
• If it truly turns out to be inexplicable, make post on Qt bug forum.

PS: rename to TestQt.tar.bz2
PS: cheating failed, the project can't be downloaded

• Tell us what version of Qt and what platform.

• Qt 5.13.1 AMD64
• OS: Manjaro xfce AMD64

• Request someone kind who fancies compiling. @mrjj is known to be very helpful at trying other people's UI stuff. :) :)
• Compare their result to yours.

I'll try it on Winows later.

No need to upload something (it doesn't work) - 10 lines of code are enough:

#include <QtWidgets>
int main(int argc, char **argv)
{
    QApplication app(argc, argv);
    
    QStringListModel model({"A", "B", "C", "D", "E", "F"});
    QTableView tv;
    tv.setModel(&model);
    tv.setSortingEnabled(true);
    tv.horizontalHeader()->setSortIndicatorShown(true);
    tv.show();
    return app.exec();
}

This is working fine for me.

@Christian-Ehrlicher
Thank you
It doesn't work for me.

[Christian Ehrlicher]

What style is this? Did you compile Qt by yourself? Please try with fusion style ("-style fusion")

[mrjj]

Hi
Just as a note.
works on Win 10.

Linux Mint

so it seems related to Arch linux.

@Christian-Ehrlicher said in QTableView sort indicator not shows:

What style is this?

default style of Manjaro xfce

Did you compile Qt by yourself?

No, installed by pacman

Please try with fusion style ("-style fusion")

Do you mean compile Qt with -style fusion?

@jronald said in QTableView sort indicator not shows:

Compile Qt with -style fusion?

No, start the app with this parameter.

No, start the app with this parameter.

Nice, any way to built in the style?
BTW, "Qt5 Settings (Qt5 Configuration Tool)" can change the style used by the demo.

Thanks

In your main() put QApplication::setStyle(QStyleFactory::create("Fusion"));
