With this I'm getting resembling what I mean by "Dynamic Layout Scaling", still missing font scaling and is a bit hack.

Does Ultimate++ provide something like this or have anyone done something like this ?

- CalculatorDynLayout.h

#ifndef _CalculatorDynLayout_CalculatorDynLayout_h
#define _CalculatorDynLayout_CalculatorDynLayout_h

#include <CtrlLib/CtrlLib.h>

using namespace Upp;

#define LAYOUTFILE <CalculatorDynLayout/CalculatorDynLayout.lay>
#include <CtrlCore/lay.h>

class CalculatorDynLayout : public WithCalculatorDynLayoutLayout<TopWindow> {
	Rect initSize;
	Vector<Rect> childInitSizes;
public:
	CalculatorDynLayout();
	virtual void Layout();
};

#endif

- main.cpp

#include "CalculatorDynLayout.h"

CalculatorDynLayout::CalculatorDynLayout()
{
	CtrlLayout(*this, "Calculator");
}

void CalculatorDynLayout::Layout()
{
	if(childInitSizes.GetCount() == 0)
	{
		initSize = this->GetRect();
		for(int i=0, imax=this->GetChildCount(); i < imax; ++i)
		{
			childInitSizes.Add(this->GetIndexChild(i)->GetRect());
		}
	}
	else
	{
		Rect currSize = this->GetRect();
		double cxRatio = (currSize.right-currSize.left) / ((double)(initSize.right-initSize.left));
		double cyRatio = (currSize.bottom-currSize.top) / ((double)(initSize.bottom-initSize.top));
		entry.SetLabel(String() << initSize << "::" << currSize
			<< "::" << cxRatio << "::" << cyRatio
			<< "::" << childInitSizes.GetCount() << "::" << this->GetChildCount());
	
		for(int i=0, imax=this->GetChildCount(); i < imax; ++i)
		{
			Rect newSize, childSize;
			childSize = childInitSizes[i];
			Ctrl *childCtrl = this->GetIndexChild(i);
			newSize.left = childSize.left * cxRatio;
			newSize.top = childSize.top * cyRatio;
			newSize.right = childSize.right * cxRatio;
			newSize.bottom = childSize.bottom * cyRatio;
			childCtrl->SetRect(newSize);
		}
	}
}

	CalculatorDynLayout().Sizeable().Run();
