QTextCharFormat setfont not working

[IknowQT]

 // [ Text 폰트 사이즈 변경 ]
    QFont f("Arial", 140, QFont::Bold);
    QTextCharFormat format = cursor.charFormat();
    format.setFont(f);
    //format.setFontPointSize(140);
    //cursor.setCharFormat(format);
    cursor.mergeCharFormat(format);

Can you look at my code? The font attribute is not applied, so I want to change the text size or font.

@IknowQT try with: ui.textEdit->setTextCursor(cursor);

@IknowQT what is cursor? please provide a minimal and compilable example.

[IknowQT]

QTextCursor cursor(this->ui.textEdit->textCursor());
cursor.movePosition(QTextCursor::Start);
   
    // 프레임 생성 
	
	QTextFrame* topFrame = cursor.currentFrame();
	QTextFrameFormat topFrameFormat = topFrame->frameFormat();
	topFrameFormat.setPadding(16);                                  // 전체 Padding 여백
	topFrame->setFrameFormat(topFrameFormat);
	
    QFont f("Bahnschrift SemiBold", 30);
	QTextCharFormat textFormat;
    textFormat.setFont(f);

    QTextFrameFormat referenceFrameFormat;
    referenceFrameFormat.setBorder(1);
    referenceFrameFormat.setPadding(8);
    referenceFrameFormat.setPosition(QTextFrameFormat::InFlow);
    referenceFrameFormat.setWidth(QTextLength(QTextLength::VariableLength, 40));
    cursor.insertFrame(referenceFrameFormat);


	// [ 제목 표시줄 생성 ]
	{
        // [ Text 가운데 정렬 코드 ]		
        QTextBlockFormat textBlockFormat = cursor.blockFormat();
        textBlockFormat.setAlignment(Qt::AlignCenter);
		cursor.mergeBlockFormat(textBlockFormat);

		cursor.insertText("Measure Summary", textFormat);
		cursor.setPosition(topFrame->lastPosition());
	}

    // [ 측정 정보 란 생성 ]
    {
        QTextBlockFormat textBlockFormat1 = cursor.blockFormat();
        textBlockFormat1.setAlignment(Qt::AlignCenter);
        cursor.mergeBlockFormat(textBlockFormat1);

        textFormat.setFontPointSize(15);       
        referenceFrameFormat.setPosition(QTextFrameFormat::FloatRight);
        referenceFrameFormat.setWidth(QTextLength(QTextLength::PercentageLength, 25));
        
        cursor.insertFrame(referenceFrameFormat);
        cursor.insertText("Measure Info", textFormat);
        cursor.insertBlock();

        textFormat.setFontPointSize(10);
        cursor.insertText("Report Time\t[data]", textFormat);
        cursor.insertBlock();
        cursor.insertText("Operator\t[data]", textFormat);
        cursor.insertBlock();
        cursor.insertText("Instrument\t[data]", textFormat);
        cursor.insertBlock();
        cursor.insertText("Version\t[data]", textFormat);
        cursor.insertBlock();
        cursor.insertText("Temperature\t[data]", textFormat);
    }

QTextBlockFormat textBlockFormat1 = cursor.blockFormat();
        textBlockFormat1.setAlignment(Qt::AlignCenter);
        cursor.mergeBlockFormat(textBlockFormat1);

The 2nd QTextBlockFormat's text can't be aligned either.
