Some Questions about graphicsView

Im currently working on a small tool, that should just have a grid, clickable labels/buttons in each grid, and small picture on those and text in front of it.
I got everything to work, which looks good. The Code looks like this:
auto scene2 = new QGraphicsScene(ui->graphicsView_2); ui->graphicsView_2->setScene(scene2); auto document2 = new QTextDocument; QTextCharFormat charFormat2; charFormat2.setFont(QFont("Arial", 50)); QPen outlinePen2 = QPen (QColor(0, 0, 0), 1, Qt::SolidLine); charFormat2.setTextOutline(outlinePen2); QTextCursor cursor2 = QTextCursor(document2); cursor2.insertText("TEST", charFormat2); auto textItem2 = new QGraphicsTextItem(); textItem2->setDefaultTextColor(Qt::white); textItem2->setDocument(document2); textItem2->setTextInteractionFlags(Qt::TextEditable); scene2->addItem(textItem2); ui->graphicsView_2->setStyleSheet("background-image:url('test.jpg')");
On first load, the background image is there, and the Text is centert. Now the Problem:
When i change the Text with the following code, it wont re-center the Text, which looks werid then.
cursor2.select(QTextCursor::Document); cursor2.removeSelectedText(); cursor2.clearSelection(); cursor2.movePosition(QTextCursor::Start); QTextCharFormat charFormat; charFormat.setFont(QFont("Arial", 50)); QPen outlinePen = QPen(QColor(0, 0, 0), 1, Qt::SolidLine); charFormat.setTextOutline(outlinePen); cursor2.insertText(NewText, charFormat);
This looks like that in the Grid:
How can i re-center the text?
Another Question would then be, how can i make my Text Multiline, but both lines are centerd themself? Currently, when i insert the text with "TEXTTEXT\nTEXT", then there are 2 lines, but the second one starts on the same point as the first one, resulting in not-looking-good.
To the Question why i used a graphicsview and not just a qtlabel or something else - I want to have that text-outline. And on google i found only this. If there is another way for that, i would be happy to change it.
Hope someone can help ;)
For your alignment question, shouldn't you just set the alignment of the QTextBlockFormat to
As for your primary problem, do you have any spaces around there ?

Thanks for Reply and the point to QTextBlockFormat. It now does center it perfectly in the horizonale. but not in the vertical one. i tried to change the alignment to Qt::AlignCenter (which should be horizonal and vertical together), and also just Qt::AlignVCenter didnt help.
Anything i did wrong?
