Singleton instance of QSplashScreen

[prakash02]

@SplashScreen* SplashScreen::m_pInstance = NULL;

SplashScreen* SplashScreen::getInstance() {

if(NULL == m_pInstance ) {

m_pInstance = new SplashScreen();

}
return m_pInstance;
}

void SplashScreen::destroyInstance() {

delete m_pInstance;
m_pInstance = NULL;
}

void SplashScreen::SetMessage(const std::wstring& message ) {

progressText = message.c_str();
char pC = (char)(LPCTSTR)progressText ;
splashMessage->append(QString::fromAscii(pC));
hostSplash_->showMessage(*splashMessage);

}
void SplashScreen::SetSplashScreen() {
hostSplash_ = new QSplashScreen(QPixmap(":Resource Files/splash.jpg"));
}@

prakash02, and?

[prakash02]

This is .cpp file.

I initialized the QApplication in main function, but my doubt does i can use the SplashScreen instance other than from main class.

Any help is appreciable.Thanks in advance.

prakash02, @SplashScreen* SplashScreen::m_pInstance = NULL;@ it's C style, it's better to use C++ style:
@SplashScreen* SplashScreen::m_pInstance = 0;@

And why do you use std::wstring instead QString?

[prakash02]

I defined resource file of strings,now i want to use those messages to be display on QSplashScreen when the program execution calls that function which can be on different namespace or on different class.

Why do you use CString and std::wstring for setting/storing text? Why not QString? Also using CString and LPCTSTR type will break cross-platform compatibility.

prakash02, how do you defiine resource file of strings?

[prakash02]

Yes i can use QString, but previously those are used to display on the native windows dialog.Now I want to change those to QT to improve the look and feel.

try to use QObject::tr("") for strings instead string table in resource file.
