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);
}


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()?
