how do I use comboBox

[QT++]

I want to use a comboBox but am having some problems with the signals. I want to have comboBox with the options

cat
dog
mouse

then when I click a pushButton (which I have already tested and coded) it calls the appropriate function. So the pushButton has the option of calling 3 different functions depending if the user has selected cat, dog or mouse from the comboBox. I know the code below isn't right but hopefully explains the idea.

if (comboBox == cat){
cat();
}
 
if (comboBox == dog){
dog();
}

if (comboBox == cat){
cat();
}

if (comboBox == dog){
dog();
}

To copy to clipboard, switch view to plain text mode

And what is the question?

What is the code to achieve what I have explained above.

And I dind't understand the use of QPushButton in your requirement.
But you can invoke this signal - void currentIndexChanged(const QString & text)

I think this helps

connect(comboBox, SIGNAL(currentIndexChanged(QString)), this, SLOT(onComboIndexChanged(QString)));
 
// Write your slot something like this
void CYourClass::onComboIndexChanged(QString str)
{
  if(str == "cat")
  {
    cat();
  }
  else if(str == "dog")
  {
    dog();
  }
}

connect(comboBox, SIGNAL(currentIndexChanged(QString)), this, SLOT(onComboIndexChanged(QString)));

// Write your slot something like this
void CYourClass::onComboIndexChanged(QString str)
{
  if(str == "cat")
  {
    cat();
  }
  else if(str == "dog")
  {
    dog();
  }
}

Connect to the button's clicked() signal and check the current index of the combobox.

[anda_skoa]

if (comboBox->currentText() == "cat")

if (comboBox->currentText() == "cat")

To copy to clipboard, switch view to plain text mode 

or, if you know that "cat" is the first option, as wysota said

if (comboBox->currentIndex() == 0)

if (comboBox->currentIndex() == 0)

To copy to clipboard, switch view to plain text mode
