View Full Version : [solved] Translation context vs namespaces

Hello,

I have created namespaces for my modules in my project so that every sub module lives in its own namespace. Eg for the viewer classes I created the namespace ViewerUI like this in class MainWindow:



#include <QMainWindow>

namespace SubModule1
{
class HelperClass1
}
namespace SubModule2
{
class HelperClass2;
}

namespace ViewerUI
{
class MainWindow : public QMainWindow
{
public:
MainWindow(int argc, char* argv[]);

~MainWindiw();

[...]

void setHelperClass1(const SubModule1::HelperClass1* hc);

[...]
private:
HelperClass1* mHelperClass;
};
}


Using this namespace in cpp file:


#include "MainWindow.h"

namespace ViewerUI
{
using SubModule1::HelperClass1;

MainWindow::MainWindiw(int argc, char* argv[]) : QMainWindiw(argc, argv)
{
[...]
QTranslator* t = new QTranslator(this);
t->load(":/Viewer_de");
installTranslator(translator);
[...]
}

[...]
void setHelperClass1(const SubModule1::HelperClass1* hc)
{
mHelperClass = hc;
QString t = tr("Test output should be translated here!");
}
[...]
}

Installing the created translator in constructor of MainWindow class without namespaces results in translation of strings enclosed with tr() macro. But if I use namespaces, strings are no more translated to german.

In assistant docs to QObject there is an issue of so called translation contexts, using Q_OBJECT in a class derived from QObject results in setting the translation context to the name of the subclass? Don't understand this. I want to have translated strings everywhere in the project not just in main window class.

Any hints & help appreciated,
AlGaN

Edit: Ok, not to mind anymore, a new lupdate execution collected the translatable strings in a new translation context containing namespaces and classes. Thanks & Greetiongs :)
