Fix game window width/height setting being broken when using Arabic locale
Qt displays numbers differently in Arabic. The spinbox window height/width used
getText instead of value to get the value, which was wrong because this gets
the user-facing string (in arabic) instead of the number to use internally.
#include <QGuiApplication>
#include <QQmlApplicationEngine>
int main(int argc, char *argv[])
{
QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
QGuiApplication app(argc, argv);
QQmlApplicationEngine engine;
engine.load(QUrl(QLatin1String("qrc:/main.qml")));
if (engine.rootObjects().isEmpty())
return -1;
return app.exec();
}
