QSplashScreen with QProgressBar

[Ratheendrans]

Hi All,


I want to put a Splash Screen with a progress bar showing the update,I have seen some of the example on Internet they are either incomplete or do not work.


can any give me a sample code example of implementation ,or links to working example.

Thanks,

QProgressBar syntax

QProgressBar *pbar = new QProgressBar();
    pBar->setMinimum(0);
    pBar->setMaximum(100);

QProgressBar *pbar = new QProgressBar();
    pBar->setMinimum(0);
    pBar->setMaximum(100);

To copy to clipboard, switch view to plain text mode 

hope it helps

Hi All,

I tried including progress bar in QSplashScreen with some success.
However I am not aware on updating the progress bar from the main progamme.

I am sharing the code below,in this code drawContents() is called only once.

class customSplashScreen: public QSplashScreen
{
QProgressBar *m_pProgressBar;
public:
customSplashScreen(const QPixmap& pixmap);
~customSplashScreen();

virtual void drawContents(QPainter *painter);
};

customSplashScreen::customSplashScreen(const QPixmap& pixmap):QSplashScreen(pixmap)
{
m_pProgressBar = new QProgressBar (this);
m_pProgressBar->setMinimum(0);
m_pProgressBar->setMaximum(100);
m_pProgressBar->show();

};

customSplashScreen::~customSplashScreen()
{
};

void customSplashScreen::drawContents(QPainter *painter)
{
m_pProgressBar->setValue(24);
m_pProgressBar->update ();
};

2.now in my main.cpp
main()
{
QPixmap pixmap("/home/sky/myimage.png");
customSplashScreen *splash = new customSplashScreen(pixmap);
splash->show();
// do some task and update the progress bar finally calling my main application

}

Kindly give your valuable suggestions.

Thanks and Regards,
