Where do i change the label on clicking a button QT - forms

Question

i made a GUI for a project, it has multiple forms and i don't know how to connect them.....the thing is that the navigation between these forms is not linear.
The user's choice on the first page (radiobuttons) decides what the next form will be, i developed a basic algorithm using if statements, but i don't know the navigation action.
here's the if statement
void InputChoice::on_commandLinkButton_clicked()
{
if (ui->radioButton->isChecked()){
//Go to state vector input;
}
if (ui->radioButton_2->isChecked()){
//Go to orbital element input
}
if (ui->radioButton_3->isChecked()){
//Go to TLE input
}
So i want to know
1- the syntax and/or the principal that we use to link the forms together.
2- How can i put it in a conditional statement.
3- i read in some place that it would be a good option to use the command link button
Thanks alot :))

Answer 1

void InputChoice::on_commandLinkButton_clicked() {
if (ui->radioButton->isChecked()){
//Go to state vector input;
vectorInput = new VectorInput(); // show the form
vectorInput->exec(); // Don't let anything else happen until choice is made on form
//or you could also just use show(); but the user can do other things while form is showing
vectorInput = new VectorInput();// show the form
vectorInput->show();
}
else if (ui->radioButton_2->isChecked()){
//Go to orbital element input
//Same as above
}
else if (ui->radioButton_3->isChecked()){
//Go to TLE input`enter code here`
//same as above
}
else{
//Do something.
}
//Should be something like this. If not, can you elaborate a little more or where can I see the code?
