如何从 QTabWIdget C++ 读取 textedit 对象的文本？

Question

I have called same TextEdit object whenever new tab is created. But the text on other tabs are inaccessible. How can I get the text from other TextEdit that are opened in new tabs.

I am trying to save text in a file.

same TextEdit in every new tab

void MainWindow::on_actionsavew_triggered()
{
    QString file_name = QFileDialog::getSaveFileName(this,"Open the file","X://");
        QFile file(file_name);
        if(!file.open(QFile::WriteOnly | QFile::Text)){
            QMessageBox::warning(this,"Error","File not Open");
            return;
        }
        QTextStream out(&file);
        QString text = ui->textEdit->toPlainText();
       out<<text;
       file.flush();
       file.close();
}

Answer 1

this here

QString text = ui->textEdit->toPlainText();

is aa hint to us indicating that you are actually adding those widgets to the tabs and windows using the qt designer in qt creator, therefore you can access ANY widget and its attributes using the same approach

eg

do

QString textFromTab1 = ui->textEditInTab1->toPlainText();
