Updating MainWindow from slot

Hi,

I have the following slot -

Qt Code:

Switch view

QObject::connect(ui.addCasePushButton, SIGNAL(clicked ()), this, SLOT(browseToCaseFile()));
 
void SelectCaseWindow::browseToCaseFile()
{
	QString fileName = QFileDialog::getOpenFileName(this, tr("Browse to Case File"), "/home/", tr("Case Files (*.cas)"));
 
	repaint();
 
	// if a file is selected
	if(!fileName.isEmpty())
		localCaseList->addLocally(QDir(fileName));
}

QObject::connect(ui.addCasePushButton, SIGNAL(clicked ()), this, SLOT(browseToCaseFile()));

void SelectCaseWindow::browseToCaseFile()
{
	QString fileName = QFileDialog::getOpenFileName(this, tr("Browse to Case File"), "/home/", tr("Case Files (*.cas)"));

	repaint();

	// if a file is selected
	if(!fileName.isEmpty())
		localCaseList->addLocally(QDir(fileName));
}

To copy to clipboard, switch view to plain text mode

The problem is that addLocally takes about 20 seconds to process. As a result, there is a grey patch over the SelectCaseWindow where the file dialog was, which disappears after the slot function completes. What can I do to update this region of the screen before I call addLocally? The repaint doesn't seem to do anything.

I'm working on Ubuntu 9.04.

Thanks,

Barry.
