Managing string resources in Qt - qt

Question

I have a string that I need at various points in my program. I know that Qt can manage image resources, but I need similar functionality for a couple of strings. Currently I'm using a string resource class, which is a sloppy solution.
class StringRes {
public:
static const QString& appName() { return _appName; }
static const QString& appVersion() { return _appVersion; }
private:
static const QString _appName;
static const QString _appVersion;
};
Besides, this solution causes a segfault at a certain point in my code.
_fileStream << QString("This is ")
+ StringRes::appName()
+ " "
+ StringRes::appVersion()
+ " reporting for duty.\n";
How do Qt programmers (or C++ programmers in general) manage their string resources?

For storing just application's name and version and organization's name and domain you can use QCoreApplications's properties applicationName, applicationVersion, organizationDomain and organizationName.
I usually set them in main() function:
#include <QApplication>
#include "MainWindow.h"
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
// These functions are member of QCoreApplication, QApplication's
// parent class:
app.setApplicationName("My Application");
app.setApplicationVersion("3.5.2");
app.setOrganizationName("My Company, or just My Name");
app.setOrganizationDomain("http://example.com/");
MainWindow window;
window.show();
return app.exec();
}
And I can use them to show a nice about message:
#include "MainWindow.h"
#include <QCoreApplication>
...
// Slot called when ? -> About menu is clicked.
void MainWindow::on_aboutAction_triggered()
{
QString message = tr("<strong>%1</strong> %2<br />"
"Developed by %3")
.arg(QCoreApplication::applicationName())
.arg(QCoreApplication::applicationVersion())
.arg(QString("%2")
.arg(QCoreApplication::organizationDomain())
.arg(QCoreApplication::organizationName()))
;
QMessageBox::about(this, tr("About"), message);
}
