Signal if application is translating?

[whitefurrows]

Hi,

i use this Example for dynamic translation.

How can i verify if my applicatin begin and end translating? I have try to send a signal:

application.h

class Application : public QApplication
{
	Q_OBJECT
 
public:
	explicit Application(int& argc, char* argv[]);
	~Application();
 
	//...
 
public slots:
	static void setLanguage(const QString& locale);
	// ...
 
signals:
	static void languageChanging(int);
};

class Application : public QApplication
{
	Q_OBJECT

public:
	explicit Application(int& argc, char* argv[]);
	~Application();

	//...

public slots:
	static void setLanguage(const QString& locale);
	// ...

signals:
	static void languageChanging(int);
};

To copy to clipboard, switch view to plain text mode 

application.cpp

void Application::setLanguage(const QString& locale)
{
	emit languageChanging(true);
 
	// remove previous
	if (current)
	{
		removeTranslator(current);
	}
 
	// install new
	current = translators.value(locale, 0);
	if (current)
	{
		installTranslator(current);
	}
 
	emit languageChanging(false);
}

void Application::setLanguage(const QString& locale)
{
	emit languageChanging(true);

	// remove previous
	if (current)
	{
		removeTranslator(current);
	}

	// install new
	current = translators.value(locale, 0);
	if (current)
	{
		installTranslator(current);
	}

	emit languageChanging(false);
}

To copy to clipboard, switch view to plain text mode 

but my compiler say error ... : static member functions do not have 'this' pointers
and i think thats OK but what can i do?

Chaning the translation language is done using events so a synchronous code such as your wouldn't make any sense. If you want, you can monitor the application (using event filters) for LanguageChange events. When they will stop comming, it means the changes have propagated themselves.

In the case you are about to remove your own translation monitoring, my intervention is useless.

But I can't stop me to tell you that the message your compiler displays is right : installTranslator and removeTranslator are not static, are they?

That’s right.

The problem was my QTreeWidget has send the signal currentItemChanged () if the language changing. But the bug was i have call a function in LanguageChange event. Now it’s all OK.

Thanks for your Help
