◆ updateCanvasSizeEstimate()

void UMLScene::updateCanvasSizeEstimate	(	qreal	x,
		qreal	y,
		qreal	w,

Unfortunately the XMI attributes "canvaswidth" and "canvasheight" cannot be relied on, in versions before 2.34 they sometimes contain bogus values. We work around this problem by gathering the minimum and maximum values of the widgets x, x+width, y, y+height into the variables m_minX, m_maxX, m_minY, m_maxY. These values are gathered, and the new scene rectangle is set if required, during loadFromXMI().

Parameters

x	If value is less than m_minX then m_minX is set to this value.
y	If value is less than m_minY then m_minY is set to this value.
w	If `x` plus this value is greater than m_maxX then m_maxX is set to their sum.
h	If `y` plus this value is greater than m_maxY then m_maxY is set to their sum.
