problem connect signal - slot

[aamer4yu]

Can you tell the declaration of groupBox2 ?

You need to write your own slot which will call setEnabled() for the second groupbox. Here what the documentation says about toggled(bool) signal:

If the group box is checkable, this signal is emitted when the check box is toggled. on is true if the check box is checked; otherwise it is false.

If the group box is checkable, this signal is emitted when the check box is toggled. on is true if the check box is checked; otherwise it is false.

It means that when you enable your first group box the signal is emitted with 'true' and as a result you call setEnabled(true) for your second group box. But as I understand you need to to invert that bool flag. The same thing with clicked() signal.

You need your own signal, smth like this:

connect(groupBox1, SIGNAL(toggled(bool)), this,  SLOT(mySlot(bool)));
...
void
mySlot(bool ipFlag)
{
    groupBox2->setEnabled(!ipFlag);
}

connect(groupBox1, SIGNAL(toggled(bool)), this,  SLOT(mySlot(bool)));
...
void
mySlot(bool ipFlag)
{
    groupBox2->setEnabled(!ipFlag);
}

connect(groupBox1, SIGNAL(toggled(bool)), this,  SLOT(mySlot(bool)));
...
void
mySlot(bool ipFlag)
{
    groupBox2->setEnabled(!ipFlag);
}

connect(groupBox1, SIGNAL(toggled(bool)), this,  SLOT(mySlot(bool)));
...
void
mySlot(bool ipFlag)
{
    groupBox2->setEnabled(!ipFlag);
}

To copy to clipboard, switch view to plain text mode 

For that you can simply use QWidget::setDisabled().

connect(groupBox1, SIGNAL(toggled(bool)), groupBox2,  SLOT(setDisabled(bool)));

connect(groupBox1, SIGNAL(toggled(bool)), groupBox2,  SLOT(setDisabled(bool)));
