how to call or change the text of a lineEdit which locates in another cpp

Hi all,
how can i reach the lineEdit which locates in another cpp?ui->roomnolineEdit->setText(qry.value(0).toString()); what i know all is not like this...

Hi,
Have a look at the signals and slots chapter of Qt's documentation. Basically, your widget handling the query should emit a signal containing that string value, and in your other widget, you implement a slot that will call
ui->roomnolineEdit->setText()
. Doing so also allows you to avoid tight coupling between your widgets.Hope it helps
