problem with ui->pushButton->text()

[sax94]

hy,
i'm trying to create my first GUI application, I wanted to create a simple timer application, there is just one button on the interface with START write on it, when I press it I want my timer to start and the text to be changed in STOP. I can manage this, the problem is that when the text is STOP I want the timer to stop, to do this I have to undestrand if the button has got START or STOP write in it. I tried with

void MainWindow::on_pushButton_clicked()
{
    if(ui->pushButton->text()=="START")
    {
        ui->pushButton->setText("STOP");
    }
    else if(ui->pushButton->text()=="STOP")
    {
        ui->pushButton->setText("START");
    }
}

void MainWindow::on_pushButton_clicked()
{
    if(ui->pushButton->text()=="START")
    {
        ui->pushButton->setText("STOP");
    }
    else if(ui->pushButton->text()=="STOP")
    {
        ui->pushButton->setText("START");
    }
}

To copy to clipboard, switch view to plain text mode 

but none of this statements seems to be true!
can someone help me?
thank's

try this...

void MainWindow::on_pushButton_clicked()
    {
    if(ui->pushButton->text()== QString ("START"))
    {
    ui->pushButton->setText("STOP");
    }
    else if(ui->pushButton->text()== QString ("STOP"))
    {
    ui->pushButton->setText("START");
    }
    }

void MainWindow::on_pushButton_clicked()
    {
    if(ui->pushButton->text()== QString ("START"))
    {
    ui->pushButton->setText("STOP");
    }
    else if(ui->pushButton->text()== QString ("STOP"))
    {
    ui->pushButton->setText("START");
    }
    }

... then the button text is neither "START" nor "STOP". What do you want us to do about it? Have you thought to look at what the button text actually is? Perhaps the text is "&START" because you set a shortcut character. Perhaps the text is actually "Start". Perhaps this code is never reached.

thank's for your help, solved the problem, don't know why, tried to restart everything and worked just fine!

Changing the button text like that is not a very clever solution. Better have two buttons and either disable or hide one of them when the other one is active.
