connect button to stackWidget and radioButton to comboBox

isan

I want to connect pushButton to stackWidget index I used

connect(ui->user, SIGNAL(clicked(bool)), ui->stackedWidget,SLOT(setCurrentIndex(int)));

It is not complete and it does not work

And to connect radioButton to the comboBox (if radioButton was hit, comboBox would be enabled) I used

connect(ui->radioButton_co,SIGNAL(clicked()),ui->comboBox_co,SLOT(setEnabled(bool)));

It also not complete and it does not work
How should I do this without defining any function?

Hi
connect(ui->user, SIGNAL(clicked(bool)), ui->stackedWidget,SLOT(setCurrentIndex(int)));

Can never work as clicked can maximum send a bool and
setCurrentIndex expects and int that tells what index to go to.

What do u try to make it do with one button ?

for combobox
connect(ui->radioButton_co,SIGNAL(clicked(bool)),ui->comboBox_co,SLOT(setEnabled(bool)));
should work.
But not sure it works as you want as radio buttons normally comes in a group.
If you just have 1 radiobutton, its not possible to unselect it again.

If just to enable combo, then QCheckbox might be better.

I did this to change the page

void Healthy::on_user_clicked()
{
    ui->stackedWidget->setCurrentIndex(5);
}

But I want to use a connection to do this
comboBox is disabled for the first time

ui->comboBox_co->setDisabled(1);

I used QCheckBox, but when checking QCheckBox ,the comboBox is not enabled

connect(ui->checkBox_co,SIGNAL(clicked()),ui->comboBox_co,SLOT(setEnabled(bool)));

when I run the program I get this

QObject::connect: Incompatible sender/receiver arguments
        QCheckBox::clicked() --> QComboBox::setEnabled(bool)

Hi
But dont u need to slots like
nextPage and prevPage ?
to go back and forth. You can use lambdas for compact design.

you forgot the parameter type
connect(ui->checkBox_co,SIGNAL(clicked(bool)),ui->comboBox_co,SLOT(setEnabled(bool)));
also connects return true/false so u can spot when you have made error.

connect(ui->checkBox_co,SIGNAL(clicked(bool)),ui->comboBox_co,SLOT(setEnabled(bool)));

And I use this for change page

connect(ui->user, &QAbstractButton::clicked, [=](bool b){ui->stackedWidget->setCurrentIndex(5);});

it work thanks to u

Ok super.
So you just need button to go exact page. and not navigate back and forth.
