QT GUI Help

Hey guys

 

Does anyone here know how can I find a word in the QTextEdit and change the color of it. 

 

Thanks for your help and remember that no idea is a bad idea.

You could try and use HTML markup (setHTML) instead of simply raw text and a stylesheet.

You'd have to search the text and replace it, eg:

string.replace( 'myword', '<font color="#FBFBFB">myword</font>' )

Thanks, but I have solved it.

 

The solution:

QString searchString = ui_lineEdit->text();
    QTextDocument *document = ui_textEdit->document();

    bool found = false;

    if (isFirstTime == false)
        document->undo();

    if (searchString.isEmpty()) {
        QMessageBox::information(this, tr("Empty Search Field"),
                "The search field is empty. Please enter a word and click Find.");
    } else {

        QTextCursor highlightCursor(document);
        QTextCursor cursor(document);

        cursor.beginEditBlock();

        QTextCharFormat plainFormat(highlightCursor.charFormat());
        QTextCharFormat colorFormat = plainFormat;
        colorFormat.setForeground(Qt::red);

        while (!highlightCursor.isNull() && !highlightCursor.atEnd()) {
            highlightCursor = document->find(searchString, highlightCursor, QTextDocument::FindWholeWords);

            if (!highlightCursor.isNull()) {
                found = true;
                highlightCursor.movePosition(QTextCursor::WordRight,
                                       QTextCursor::KeepAnchor);
                highlightCursor.mergeCharFormat(colorFormat);
            }
        }

        cursor.endEditBlock();
        isFirstTime = false;

        if (found == false) {
            QMessageBox::information(this, tr("Word Not Found"),
                "Sorry, the word cannot be found.");
        }
    }
