Qt C ++如何在textedit的开头获取光标？

Question

Basically I made a simple search function, however it only works if the user moves the cursor to beginning of the textedit. I was wondering if there was anything I can do to make the cursor automatically appear there. Any input would be greatly appreciated.

void Dialog::on_pushButton_clicked()
{
    QString month;
    QString day;
    QString year;

    month=ui->comboBox->currentText();
    day=ui->comboBox_2->currentText();
    year=ui->comboBox_3->currentText();

    QTextCursor textCursor = ui->textEdit->textCursor();
    textCursor.movePosition(QTextCursor::Start, QTextCursor::MoveAnchor,1);

    QString date= month + "/" + day + "/" + year;
    qDebug() << date;
    ui->textEdit->find(date, QTextDocument::FindWholeWords);

}

You were almost to the result.

By using QTextEdit::setTextCursor , you can move the visible cursor where you want:

QTextCursor textCursor = ui->textEdit->textCursor();
textCursor.movePosition(QTextCursor::Start, QTextCursor::MoveAnchor,1);
ui->textEdit->setTextCursor(textCursor); // The line to add
