QTextCursor cursor = textEdit->textCursor(); QTextBlockFormat blockFmt; blockFmt.setAlignment(Qt::AlignCenter); cursor.setBlockFormat(blockFmt);
QTextCursor cursor = textEdit->textCursor(); QTextBlockFormat blockFmt; blockFmt.setIndent(2); cursor.setBlockFormat(blockFmt);In this example, we create a QTextBlockFormat object and set its indent property to 2. We then call the setBlockFormat function on a QTextCursor object, passing in the block format. This code will indent the current paragraph that the cursor is positioned on by 2 spaces. Overall, the QTextCursor setBlockFormat function is a useful tool for managing text formatting in Qt applications. Its ability to set text properties such as alignment and indentation allows developers to create professional-looking documents with ease.
