How to disable the Next button in a wizard until a certain condition is met

[pkjag]

Hi all
I was wondering how i would disable the Next button in a wizard page until i have set only four checkboxes checked or clicked them among a bunch of other checkboxes in the wizard page?

So i did this:

connect(checkmeCheckBox, SIGNAL(toggled()),wizard1->button(QWizard::NextButton), SLOT(reactToToggle()));
...
...
...
//for all the checkboxes in myPage
 
int myPage::reactToToggle(bool checked)
{
    static int i = 0;
    if(checked)
        ++i;
    return i;
}
 
void myPage::returns(bool checked)
{
    if(reactToToggle(checked)== 3)
        wizard1->button(QWizard::NextButton)->setEnabled(true);
    else
        wizard1->button(QWizard::NextButton)->setDisabled(true);
}

connect(checkmeCheckBox, SIGNAL(toggled()),wizard1->button(QWizard::NextButton), SLOT(reactToToggle()));
...
...
...
//for all the checkboxes in myPage

int myPage::reactToToggle(bool checked)
{
    static int i = 0;
    if(checked)
        ++i;
    return i;
}

void myPage::returns(bool checked)
{
    if(reactToToggle(checked)== 3)
        wizard1->button(QWizard::NextButton)->setEnabled(true);
    else
        wizard1->button(QWizard::NextButton)->setDisabled(true);
}

To copy to clipboard, switch view to plain text mode 

but the compiler returns a SIGSEGV error, is there anything wrong with my implementation apart from the SIGSEGV exception???

Why didn't you use isComplete()?
