Close Dialog in showEvent

[pospiech]

If I do the following

void DialogExample::showEvent ( QShowEvent * event ) 
{
	close();
}

void DialogExample::showEvent ( QShowEvent * event ) 
{
	close();
}

To copy to clipboard, switch view to plain text mode 

The Dialog is not closed. Instead the Dialog Interface is frozen on the screen and can not be closed with the mouse anymore.

Why ? What is the solution?

The complete problem is the following

void DialogAgilentPowerSensor::showEvent ( QShowEvent * event ) 
{
	if (!m_isAgilentPowerSensorLoaded)
	{
		int ret = QMessageBox::critical(this, "Warning",
                   "Could not connect to Agilent Power Sensor",
                   QMessageBox::Cancel);		
		close();
	}
}

void DialogAgilentPowerSensor::showEvent ( QShowEvent * event ) 
{
	if (!m_isAgilentPowerSensorLoaded)
	{
		int ret = QMessageBox::critical(this, "Warning",
                   "Could not connect to Agilent Power Sensor",
                   QMessageBox::Cancel);		
		close();
	}
}

To copy to clipboard, switch view to plain text mode 

Thus, in the constructor a class is loaded and after the construction the dialog shall be closes if the device could not be loaded.
