Problems creating a ToolBar

[franco.amato]

Which code do you need? I exactly copied from the mainwindow example.
I get the icon in the menu but the toolbar is not created

void MainWindow::createToolBar()
{
	exitToolBar = addToolBar(tr("Exit"));
	exitToolBar->addAction(exitAct);
}

void MainWindow::createToolBar()
{
	exitToolBar = addToolBar(tr("Exit"));
	exitToolBar->addAction(exitAct);
}

To copy to clipboard, switch view to plain text mode 

and the action

/* Exit action */
exitAct = new QAction(QIcon(":/images/exit.png"), tr("E&xit"), this);
exitAct->setShortcut( tr("Ctrl+Q") );
exitAct->setStatusTip(tr("Exit the application"));
connect( exitAct, SIGNAL( triggered() ), this, SLOT( close() ) );

/* Exit action */
exitAct = new QAction(QIcon(":/images/exit.png"), tr("E&xit"), this);
exitAct->setShortcut( tr("Ctrl+Q") );
exitAct->setStatusTip(tr("Exit the application"));
connect( exitAct, SIGNAL( triggered() ), this, SLOT( close() ) );

To copy to clipboard, switch view to plain text mode 

the qrc file:

<RCC>
    <qresource>
        <file>images/exit.png</file>
    </qresource>
</RCC>

<RCC>
    <qresource>
        <file>images/exit.png</file>
    </qresource>
</RCC>

To copy to clipboard, switch view to plain text mode 

I don't understand why the toolbar is not created.

I solved the problem,
but now I would know if Qt support 48 x 48 icons in the toolbar because seems that only support 32 x 32.
