Strange QPrintDialog behavior on my machine

[kkk777kkk]

Hi, help me please with my problem: listed code from main.cpp work in strange case, if line "splash.show();" commented it work right, but if it is not commented QPringDialog window can't be closed it any way: all buttons responding on my clicks but nothing more not happened. Mac OS X 10.6.6 Qt 4.7.4

#include <QApplication>
#include <QPrintDialog>
#include <QPrinter>
#include <QSplashScreen>
 
int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    QSplashScreen splash;
    splash.show();
 
    QPrinter printer(QPrinter::HighResolution);QPrintDialog dialog(&printer);dialog.exec();
    return app.exec();
}

#include <QApplication>
#include <QPrintDialog>
#include <QPrinter>
#include <QSplashScreen>

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    QSplashScreen splash;
    splash.show();

    QPrinter printer(QPrinter::HighResolution);QPrintDialog dialog(&printer);dialog.exec();
    return app.exec();
}

To copy to clipboard, switch view to plain text mode

i'm using the splash screen too, but I use it like this.

int main(int argc, char** argv) {
  QApplication app(argc, argv);
 
  QPixmap pixmap("./images/splash.png");
  QSplashScreen splash(pixmap);
  splash.show();
  app.processEvents(); // this is to allow the procesing of mouse clicks over the splash to close it
 
// some more code
 
MainWindow win;
    win.resize(1024, 768);
    win.show();   
    splash.finish(&win); // this finishes the splash when the program finished loading.

int main(int argc, char** argv) {
  QApplication app(argc, argv);
    
  QPixmap pixmap("./images/splash.png");
  QSplashScreen splash(pixmap);
  splash.show();
  app.processEvents(); // this is to allow the procesing of mouse clicks over the splash to close it

// some more code

MainWindow win;
    win.resize(1024, 768);
    win.show();   
    splash.finish(&win); // this finishes the splash when the program finished loading.

Check the way i'm using the splash, I'm inclined to think that the app.processEvents(); is key to your problem.

after some more investigation i understand that it is something wrong in my environment because it works at other developer machine. that is not Qt problem but i cant understand why cocoa dialog works wrong way...
