[solved]shows splashscreen but does not show its message

tunde

i created a splashscreen for my application; however, it shows the splashscreen and then disappears but it does not show its message like loading modules and establish connections through the showMessage(). why?

attached is my code

@
#include <QtGui/QApplication>
#include "mobile.h"
#include <QSplashScreen>

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

QPixmap pixmap(":/images/mobile.jpg");
 QSplashScreen *splash = new QSplashScreen(pixmap);
 splash->show();
 a.processEvents();



 //Qt::Alignment topRight = Qt::AlignRight | Qt::AlignTop;
    splash->showMessage("Setting up the main window...");
                           //topRight, Qt::white);

a.processEvents();
splash->showMessage("Loading modules...");
//topRight, Qt::white);

a.processEvents();

        splash->showMessage("Establishing connections...");
                               //topRight, Qt::white);

a.processEvents();

mobile w;
w.show();
splash->finish(&w);
delete splash;


return a.exec(&#41;;

}

bad formating, making code hard to understand.

BTW, working sample:

But, i used QScoperPointer. You can replace it to standart pointer or non-pointer class instance.

@QApplication app(argc, argv);

QScopedPointer<QSplashScreen> splash(new QSplashScreen(QPixmap(":/splash")));
splash->show();
splash->showMessage(QSplashScreen::tr("Loading..."), Qt::AlignBottom | Qt::AlignHCenter, Qt::black);
app.processEvents();

// some code

splash->showMessage(QSplashScreen::tr("Settings Manager: loading saved settings"), Qt::AlignBottom | Qt::AlignHCenter, Qt::black);
app.processEvents();

// loading settings

splash->showMessage(QSplashScreen::tr("Plugin Manager: loading plugins"), Qt::AlignBottom | Qt::AlignHCenter, Qt::black);
app.processEvents();

// loading plugins

MainWindow w;
w.setWindowTitle(app.applicationName());
w.showMaximized();
splash->finish(&w);
int rslt = app.exec(); @

Hi,
I took the code and added a sleep, as the comments for do some stuff will not take time :-)
This code shows the texts:
@/**

this class is used to call sleep, as msleep is a protected function of QThread
/
class CxTestSleepThread : public QThread
{
public:
/*
- this method is used to call sleep, as msleep is a protected function of
- QThread
- @param nMSecs milliseconds to sleep
  */
  static void mySleep(int nMSecs)
  {
  msleep(nMSecs);
  }
  };

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

QScopedPointer<QSplashScreen> splash(new QSplashScreen(QPixmap(":/splash")));
splash->show();
splash->showMessage(QSplashScreen::tr("Loading..."), Qt::AlignBottom | Qt::AlignHCenter, Qt::white);
app.processEvents();

CxTestSleepThread::mySleep(500);
// some code

splash->showMessage(QSplashScreen::tr("Settings Manager: loading saved settings"), Qt::AlignBottom | Qt::AlignHCenter, Qt::white);
app.processEvents();

CxTestSleepThread::mySleep(500);
// loading settings

splash->showMessage(QSplashScreen::tr("Plugin Manager: loading plugins"), Qt::AlignBottom | Qt::AlignHCenter, Qt::white);
app.processEvents();

CxTestSleepThread::mySleep(500);
// loading plugins

MainWindow w;
w.setWindowTitle(app.applicationName());
w.showMaximized();
splash->finish(&w);
return app.exec();

}

Maybe you are just showing black text on a black splashscreen?

Yeah, seems to be truth
