My goal:
To fully execute one set of commands before a while loop.
Followed by a 10sec while loop during which I will have to repeat a second set of commands.
Then execute a third set of commands.

Problem:
When I run the below code the delay works, but the phase1 and phase2 commands only execute after the delay.
Why is this?

@void MainWindow::on_StartBtn_clicked()
{
ui->status_label->setText("Phase1 commands started");

//set of commands that need to run before while loop executes.

QTime FutureTime = QTime::currentTime();
FutureTime = FutureTime.addSecs(10);

while (QTime::currentTime()<= TempTime)
{
    ui->status_label->setText("Phase2 commands started");

//Set of commands that need to repeat during the while loop
}

ui->status_label->setText("Phase3 commands started");

//set of things that need to execute after while loop is done
