How to set current value in a QCombobox

I've a basic question. I've QComboBox, as follows:

   ui->comboBox_1->addItem("200ms", QVariant(0.2));
   ui->comboBox_1->addItem("500ms", QVariant(0.5));
   ui->comboBox_1->addItem("1000ms", QVariant(1));
   ui->comboBox_1->addItem("1500ms", QVariant(1.5));
   ui->comboBox_1->addItem("2000ms", QVariant(2));

How do I set the current value? for example I want combo box to show 1500ms when the program starts.

After filling combobox, set the current index through setCurrentIndex()

ui->comboBox_1->setCurrentIndex(3);

So your code becomes

ui->comboBox_1->addItem("200ms", QVariant(0.2));
ui->comboBox_1->addItem("500ms", QVariant(0.5));
ui->comboBox_1->addItem("1000ms", QVariant(1));
ui->comboBox_1->addItem("1500ms", QVariant(1.5));
ui->comboBox_1->addItem("2000ms", QVariant(2));
ui->comboBox_1->setCurrentIndex(3);
