settext

[seltra]

i have a very easy question. how can i settext an int value??

int length;
length=10;
ui->lineEdit->setText("The length is:", length);

int length;
length=10;
ui->lineEdit->setText("The length is:", length);

To copy to clipboard, switch view to plain text mode 

[tbscope]

ui->lineEdit->setText(QString("The length is: %1").arg(length));

ui->lineEdit->setText(QString("The length is: %1").arg(length));

To copy to clipboard, switch view to plain text mode 

[seltra]

ui->lineEdit->setText(QString("The length is: %1").arg(length));

ui->lineEdit->setText(QString("The length is: %1").arg(length));

To copy to clipboard, switch view to plain text mode 

thank you very much tbscope.
how can i setText with only the integer value?

ui->lineEdit->setText(arg(length));

ui->lineEdit->setText(arg(length));

To copy to clipboard, switch view to plain text mode 

[tbscope]

ui->lineEdit->setText(QString("%1").arg(length));

ui->lineEdit->setText(QString("%1").arg(length));

To copy to clipboard, switch view to plain text mode 

Or, and better:

ui->lineEdit->setText(QString::number(length));

ui->lineEdit->setText(QString::number(length));

To copy to clipboard, switch view to plain text mode
