QLabel setText not displaying text of QLineEdit if label size small

Question

I have a QLabel in which I want to show text from a QLineEdit. The size of line-edit is bigger than the label so I want to show the label ending with a dotted line

ui->LE_Serverpath// contains 20 charecters

ui->LB_UsernameInfo  // having size of 10 charecters

ui->LB_UsernameInfo->setText(ui->LE_Serverpath->text());

using wordwrap the line is getting cut but I need dotted lines at the end

ui->LB_UsernameInfo->setWordWrap(true);

You have to set an ElideMode for the label, you need a QFontMetrics instance from label font then set text elide mode for the label. to show dots by end of line, set ElidMode to Qt::ElideRight, on the text copied form QLieEdit:

//QFontMetrics metrics(ui->LB_UsernameInfo->font()); // QLabel already has font metrics

int width = ui->LB_UsernameInfo->width() - 2;
QString text = ui->LB_UsernameInfo->fontMetrics().elidedText(ui->LE_Serverpath->text(), Qt::ElideRight, width);
ui->LB_UsernameInfo->setText(text);
ui->LB_UsernameInfo->setWordWrap(true);
