how to translate key shortcut-CodePudding

I cannot force QKeySequence::toString() to return translated shortcut representation despite the fact that it documentation suggests it should work. The docs say: "The strings, "Ctrl", "Shift", etc. are translated using QObject::tr() in the "QShortcut" context." but I am not completely sure what it means by shortcut context. I am probably doing something wrong...

Here is my example. To make it work, I need to copy qtbase_es.qm from Qt installation directory to my project build directory. When the translation is correctly loaded, the action in the menu correctly shows "Action Control Intro" which is Spanish translation of the shortcut for "Action Ctrl Enter". But the tooltip on the main window is still "Action (Ctrl Enter)". I would expect it to be "Action (Control Intro)", like in the menu. What am I doing wrong?

#include <QAction>
#include <QApplication>
#include <QDebug>
#include <QMainWindow>
#include <QMenuBar>
#include <QTranslator>

int main(int argc, char *argv[])
{
    QTranslator spanish;
    qDebug() << spanish.load("qtbase_es.qm"); // should return true if correctly loaded
    QApplication a(argc, argv);
    QApplication::installTranslator(&spanish);
    QMainWindow w;
    auto menu = new QMenu("Menu");
    auto action = menu->addAction("Action");
    action->setShortcutContext(Qt::ApplicationShortcut);
    action->setShortcut(Qt::CTRL | Qt::Key_Enter);
    w.menuBar()->addMenu(menu);
    w.show();
    QApplication::processEvents(); // I also tried this line but it is useless...
    w.setToolTip(QString("%1 (%2)").arg(action->text(), action->shortcut().toString()));
    qDebug() << action->shortcut().toString(); // WRONG: returns Ctrl Enter but I expect Control Intro
    return a.exec();
}

CodePudding user response：

The QShortcut::toString has a SequenceFormat parameter, defaulted to ProtableText. The documentation of the format states, that portable format is intended for e.g. writing to a file.

The native format is intended for displaying to the user, and only this format performs translations.

Try:

qDebug() << action->shortcut().toString(QKeySequence::NativeText);
