Hi sir...,

          Am unable to display splash screen in Qt 4.8.4, in beagle board...Please help me...here is my code..

@
#include "mainwindow.h"
#include <QApplication>
#include <QSplashScreen>
#include <QTimer>
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
QSplashScreen *splash = new QSplashScreen;
splash->setPixmap(QPixmap("/home/shirisha/Documents/images.jpeg"));
splash->show();
MainWindow w;
QTimer::singleShot(2500,splash,SLOT(close()));
QTimer::singleShot(2500,&w,SLOT(show()));

Hi Shirisha,

I don't see the slot mentioned in
@QTimer::singleshot()
@

For example:
@
#include <QApplication>
#include <QTimer>

int main(int argc, char *argv[])
{
QApplication app(argc, argv);
QTimer::singleShot(600000, &app, SLOT(quit()));
...
return app.exec();
}
@

"Link to Qt documentation":http://qt-project.org/doc/qt-4.8/qtimer.html#singleShot

And may I ask, what is the real reason for using QTimer? Are you processing the program or application related files when you want to display splash screen?

shirisha

no sir i menstioned ther bt in the post unable to write..the same thing i menstoned like...

QTimer::singleShot(2500, splash, SLOT(close()));
QTimer::singleShot(2500, &app, SLOT(show()));

May be as a quick test, can you try this code?

@
#include <QApplication>
#include <QPixmap>
#include <QSplashScreen>
#include <QWidget>
#include <QMainWindow>
#include <QTimer>
#include <QThread>

class I : public QThread
{
public:
static void sleep(unsigned long secs) {
QThread::sleep(secs);
}
};

int main(int argc, char *argv[])
{

QApplication app(argc, argv);
// change this file path
QPixmap pixmap("c://paris.png"); // Insert your splash page image here
QSplashScreen splash(pixmap);
splash.show();

splash.showMessage(QObject::tr("Loading Programs........."),
Qt::AlignLeft | Qt::AlignTop, Qt::black); //This line represents the alignment of text, color and position

qApp->processEvents(); //This is used to accept a click on the screen so that user can cancel the screen

QMainWindow mainWin;
mainWin.setWindowTitle("Qt Application"); //Set the title of your main Qt Application
mainWin.resize(600, 500);
I::sleep(5); // Splash page is shown for 5 seconds

mainWin.show(); //This will maximize to fullscreen the size of your application window after the splash page displays
splash.finish(&mainWin);
return app.exec();
}

Please note: Update the image path with yours
@
”/home/shirisha/Documents/images.jpeg”
@

And just to sure, what is the file details of the images.jpeg?

Thanks!
