Make a list scrollable without the scrollbar

Report · Apr 22, 2018

I have a list called "list".

I want the scrollbar to be there, but I do want to be able to scroll the list dragging it up and down wherever I touch.

The code attached below I have used to scroll a Movieclip.

var maxY: Number = 0;

var minY: Number = Math.min(0, stage.stageHeight - list.height);

var _startY: Number;

var _startMouseY: Number;

addEventListener(MouseEvent.MOUSE_DOWN, mouseDownHandler);

function mouseDownHandler(event: MouseEvent): void {

_startY = list.y;

_startMouseY = mouseY;

stage.addEventListener(MouseEvent.MOUSE_MOVE, stage_mouseMoveHandler, false, 0, true);

stage.addEventListener(MouseEvent.MOUSE_UP, stage_mouseUpHandler, false, 0, true);

}

function stage_mouseMoveHandler(event: MouseEvent): void {

var offsetY: Number = mouseY - _startMouseY;

list.y = Math.max(Math.min(maxY, _startY + offsetY), minY);

}

function stage_mouseUpHandler(event: MouseEvent): void {

stage.removeEventListener(MouseEvent.MOUSE_MOVE, stage_mouseMoveHandler);

stage.removeEventListener(MouseEvent.MOUSE_UP, stage_mouseUpHandler);

}
