<![CDATA[[~Solved] Set Alignment in QGraphicsTextItem?]]>How do I properly align a multi-line text in a QGraphicsTextItem?
The text seems to be always left-aligned, despite specifying

@ QTextOption option = pTextItem->document()->defaultTextOption();
option.setAlignment(Qt::AlignCenter);
pTextItem->document()->setDefaultTextOption(option);@

I have also tried assigning an alignment to all text blocks - no effect.

Ideas?

Edit: I only use plain text. I have found "this Bug":https://bugreports.qt-project.org/browse/QTBUG-312 regarding html text.

I expected it to work without the text width, based on the length of the longest text line.

As a workaround, did you try to resize the item as suggested in the bug report ?

  • when the object is created (when text is still empty)
  • on every contentsChanged() signal

I've tried setting the text alignment for all text blocks

  • whenver the block count changes

Any other places I should try?

Just a question, do you set the option before or after setting the text ?
