How to draw "Draw Arc Ticks".

@IknowQT said in How to draw "Draw Arc Ticks".:

When drawing an oval progress, it seems to be a problem due to increasing the pen thickness and changing the drawing right (adjusted), but can you automatically adjust the center even if the thickness is increased?

Sorry I don't understand what you want to do.

I want to move the ellipse to the center

============================================

Add
The move to the center was successful, but why is the ellipse cut off to the sides?

void wCtrl_Indicator::drawBackGround(QPainter* painter)
{
	//QRect		drawingRect(this->rect());
	QPoint		p = this->rect().center();
	QRect drawingRect(1, 1, this->size().width(), this->size().height());
	QBrush		brushBackgnd(QColor(63, 67, 70));
	QPen		pen(QBrush(brushBackgnd), 10);
	pen.setCapStyle(Qt::FlatCap);

	painter->setPen(pen);
	painter->setBrush(brushBackgnd);
	painter->setRenderHints(QPainter::Antialiasing | QPainter::SmoothPixmapTransform);
	painter->drawArc(drawingRect, 90 * 16, ConvertAngle(m_nMax) * 16);
	/*painter->drawArc(drawingRect.center().x(), drawingRect.center().y(), this->size().width(), this->size().height(),
		90 * 16, ConvertAngle(m_nMax) * 16);*/
}

I think there's a problem with drawing right.
