[Solved] outline on a QGraphicsTextItem

eric_vi

Hello,

i am using QGraphicsTextItem on a QGraphicsScene, i would like to have my QGraphicsTextItem as outline text, i cannot find a way to achieve that... Anyone has any idea how to do it.

Thank you for your help

Without re-implementing the paint method?! hum, I'm afraid not...

However, you can you use "QGraphicsSimpleTextItem":http://doc.trolltech.com/4.6/qgraphicssimpletextitem.html?
If so, you can use setPen to set the outline color and setBrush to transparent.

hello thank you for your answer...

well QGrahicsSimpleTextItem, is not rich text and does not let me reedit the text.

So reimplementing the paint method is what i am trying to figure out but unfortunately i cannot see how to grab the text to addit to a QPainterPath (if this mecanism can work!)

i have been helped to solve that, it works, you need to have the appropriate QCharFormat setup to the QTextCursor of your QGraphicstextitem

Can you post the code here?

Here's the code.
Context:
A widget is created in designer with a QGraphicsView.
A QGraphicsScene pointer is defined as a private member of the widget.
A QTextDocument is defined as a private member of the widget (although that is not necessary, the document of the QGraphicsTextItem can be used too)
A QGraphicsTextItem is defined as a private member of the widget.

@
ui->setupUi(this);

scene = new QGraphicsScene(ui->graphicsView);
ui->graphicsView->setScene(scene);

document = new QTextDocument;

QTextCharFormat charFormat;
charFormat.setFont(QFont("times", 24));

QPen outlinePen = QPen (QColor(255, 0, 0), 1, Qt::SolidLine);
charFormat.setTextOutline(outlinePen);

QTextCursor cursor = QTextCursor(document);
cursor.insertText("Test", charFormat);

textItem = new QGraphicsTextItem();
textItem->setDocument(document);
textItem->setTextInteractionFlags(Qt::TextEditable);

scene->addItem(textItem);

Thanks for the code. =)

I've just asked that because probably someone will have the same problem in the future and a "I solved it" message will not help them =)
