Hi,

Maybe somthing like this could do the trick:

template <class T>
class BlurringDecorator : public T {
	
	private:
	bool doBlur;

	void blurImage(Image& m) {
		m = Sharpen(m, -200);
		m = Sharpen(m, -200);
		m = Sharpen(m, -200);
		m = Sharpen(m, -200);
		m = Sharpen(m, -200);
		m = Sharpen(m, -200);
	}


	public:
	
	BlurringDecorator() : doBlur(true) {}
	virtual ~BlurringDecorator() {}
	void setBlur(bool blur = true)  { doBlur = blur; }
	
	virtual void Paint(Draw& w) {
		
		if (doBlur) {
			ImageDraw dw(T::GetSize());
			T::Paint(dw);
			Image im = dw;
			blurImage(im);
			w.DrawImage(0, 0, im);
		}
		else {
			T::Paint(w);
		}
	}
	
};

In layout

BlurringDecorator<CtrlToBlur>  myCtrl;

EDIT: just tried, works fine (but only blurrs the current Ctrl ... not what is under it !!!)
