QSplashScreen question

[graciano]

This was my interpretation also.
But by the way:

#include <QtGui>
int main(int argc, char *argv[])
{
     QApplication app(argc, argv);
     QPixmap pixmap("f0.png");
     QSplashScreen splash(pixmap);
     splash.show();
     //app.processEvents();
     //...
     QMainWindow window;
     window.show();
     //splash.finish(&window);
     return app.exec();
 
}

#include <QtGui>
int main(int argc, char *argv[])
{
     QApplication app(argc, argv);
     QPixmap pixmap("f0.png");
     QSplashScreen splash(pixmap);
     splash.show();
     //app.processEvents();
     //...
     QMainWindow window;
     window.show();
     //splash.finish(&window);
     return app.exec();

}

To copy to clipboard, switch view to plain text mode 

Commented this 2 lines and both splash and main windows open at the same time. Click closes the splash.
Thought this was only possible if using app.processEventes(); !

if you read the docs again.. it says that app.processEvents() is used because app.exe() is not called yet. When your mainwindow is shown, app.exe() is called so no need of processEvents().

And in this case:

#include <QtGui/QApplication>
#include "mainwindow.h"
#include <QSplashScreen>
#include <QTimer>
 
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    QSplashScreen *splash = new QSplashScreen;
    splash->setPixmap(QPixmap("f0.png"));
    splash->show();
    splash->showMessage(QObject::trUtf8("A preparar a janela principal ..."), Qt::AlignRight|Qt::AlignTop, Qt::black);
    MainWindow w;
    QTimer::singleShot(5000, splash, SLOT(close()));
    QTimer::singleShot(5000, &w, SLOT(show()));
    //delete splash;
    return a.exec();
}

#include <QtGui/QApplication>
#include "mainwindow.h"
#include <QSplashScreen>
#include <QTimer>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    QSplashScreen *splash = new QSplashScreen;
    splash->setPixmap(QPixmap("f0.png"));
    splash->show();
    splash->showMessage(QObject::trUtf8("A preparar a janela principal ..."), Qt::AlignRight|Qt::AlignTop, Qt::black);
    MainWindow w;
    QTimer::singleShot(5000, splash, SLOT(close()));
    QTimer::singleShot(5000, &w, SLOT(show()));
    //delete splash;
    return a.exec();
}

Obviously the commented line could not work ... but where to free the used memory by the splash screen?
Thanks
