Constructor & Destructor Documentation

TStylePreview()

TStylePreview::TStylePreview	(	const TGWindow *	p,
		TStyle *	style,
		TVirtualPad *	currentPad
	)

Constructor.

Create a new window and draw a clone of currentPad->GetCanvas() in it, using the style 'style'. Thanks to that method, one can have a preview of any style with any object.
