dont want to scroll

[Santosh Reddy]

Add this in the beginning of the slot (i assume ui->horizontalLayout_2 does not have anything else, other than the layout you add)

void analysis::on_pushButton_clicked()
{
 QLayoutItem *child;
 while ((child = ui->horizontalLayout_2->takeAt(0)) != 0) {
     delete child;
 }
 
....
}

void analysis::on_pushButton_clicked()
{
 QLayoutItem *child;
 while ((child = ui->horizontalLayout_2->takeAt(0)) != 0) {
     delete child;
 }

....
}

To copy to clipboard, switch view to plain text mode
