Which is the simplest solution for popup windows dragable with text and exit button?

<action name="draglayer_text">
      <!-- 控制文字层在特定区域中垂直方向上滚动 -->
		if(%1 != dragging,
			copy(drag_currenty, y);
			copy(drag_stagey, mouse.stagey);
			draglayer_text(dragging,%2);
		  ,
			if(pressed,
				sub(dy, mouse.stagey, drag_stagey);
				add(y1, drag_currenty, dy);
				add(y2, y1, pixelheight);
				sub(y2, %2);
				if(y1 GT 0, set(y1,0));
				if(y2 LT 0, sub(y1,y2));
				copy(y,y1);
				delayedcall(0, draglayer_text(dragging,%2) );
			  );
		  );
	</action>
