How to select a line of text

[qratman]

Hi, I am very beginner myself but I tested out what Lykurg said and it works.



I created QTextEdit and QLabel with QTCreator UI editor (based on QDialog).

Added this to dialog class in header

private slots:
    void on_textEdit_clicked();

private slots:
    void on_textEdit_clicked();

To copy to clipboard, switch view to plain text mode 

Then I added this into constructor in dialog.cpp.

connect(ui->textEdit, SIGNAL(cursorPositionChanged()), this, SLOT(on_textEdit_clicked()));

connect(ui->textEdit, SIGNAL(cursorPositionChanged()), this, SLOT(on_textEdit_clicked()));

To copy to clipboard, switch view to plain text mode 

and into dialog.cpp:

void Dialog::on_textEdit_clicked()
{
    QTextCursor cursor;
    QString text;
 
    cursor = ui->textEdit->textCursor();
    cursor.movePosition(QTextCursor::StartOfBlock);
    cursor.movePosition(QTextCursor::EndOfBlock, QTextCursor::KeepAnchor);
    text = cursor.selectedText();
 
    ui->label->setText(text);
 
}

void Dialog::on_textEdit_clicked()
{
    QTextCursor cursor;
    QString text;

    cursor = ui->textEdit->textCursor();
    cursor.movePosition(QTextCursor::StartOfBlock);
    cursor.movePosition(QTextCursor::EndOfBlock, QTextCursor::KeepAnchor);
    text = cursor.selectedText();

    ui->label->setText(text);

}

To copy to clipboard, switch view to plain text mode 

Sorry, I dont use python. So you've got to translate it yourself.

Works great. I however expected the line to turn blue to indicate selection but this did not happen.
