//protected variables in header file:
        QWidget *dialog_err;
        QLabel *text;
        QDialogButtonBox *button;
        QDesktopWidget *desktop;

//////////////////////////////////////////////////////
//cpp file:
#include "DialogErrorClass.h"

DialogErrorClass::DialogErrorClass( QWidget *parent ) : QWidget(parent) {

    desktop = QApplication::desktop();

    // create window
    dialog_err = new QWidget;
    dialog_err->setObjectName( QString::fromUtf8( "DialogError" ) );
    dialog_err->move( ( ( desktop->width() - 420 ) / 2 ), ( ( desktop->height() - 93 ) / 2 ) );
    dialog_err->setWindowTitle( QApplication::translate( "DialogError", "Chyba programu", 0, QApplication::UnicodeUTF8 ) );

    //label text error message
    text = new QLabel( dialog_err );
    text->setObjectName( QString::fromUtf8( "errorMsg" ) );
    text->setGeometry( QRect( 10, 10, 400, 21 ) );
    text->setStyleSheet(QString::fromUtf8("align: right;"));

    // close button
    button = new QDialogButtonBox( QDialogButtonBox::Cancel, Qt::Horizontal, dialog_err );
    button->setObjectName( QString::fromUtf8( "closeButton" ) );
    button->setGeometry( QRect( 169, 51, 81, 32 ) );
}

void DialogErrorClass::setMessage( const char *msg ) {
    text->setText( QApplication::translate( "errorMsg", (char*)msg, 0, QApplication::UnicodeUTF8 ) );

}

void DialogErrorClass::show() {
    connect( button, SIGNAL( accepted() ), qApp, SLOT( quit() ) );
    dialog_err->show();
}

Napiš mi obsah souboru DialogErrorClass.h, mrknu se na to.

Zdravim,

problem je v tom, ze objekt button obsahuje len tlacidlo QDialogButtonBox::Cancel, ktore emituje len signal rejected (nie accepted).

Toto by uz mohlo fungovat:

connect( button, SIGNAL( rejected() ), qApp, SLOT( quit() ) );
