有谁知道是否有(像在Android)的柔性新版任何形式的庆龙preSS的姿态?
Does anyone know if there is any sort of Long-Press gesture (like on Android) in the new version of flex?
我期待在做一个列表编辑项/删除,能够在长期preSS,但我真的希望我不会有让我自己庆龙preSS的姿态与计时器和诸如此类的东西。
I'm looking to make an item in a list editable/delete-able upon long-press, but I'm really hoping I wont have to make my own Long-Press gesture with a timer and whatnot.
如果有没有内置的,没有人知道如何使远攻preSS姿态的任何资源/博客文章 - 或者,此外,如何使一个可编辑列表
If there is none built in, does anyone know of any resources/blog posts about how to make a Long-Press gesture - or, furthermore, how to make an Editable list?
flextras回答了这个问题,我只是想跟进一个code样品,似乎工作。现在,我有它只是一个弹出窗口,询问您是否想从列表中删除的项目。
flextras answered it, and I just wanted to follow up with a code sample that seems to work. For now, I have it just do a popup asking if you want to delete the item from the list.
private var deleteAlert:DeleteAlert = new DeleteAlert();
private var longPressTimer:Timer = new Timer(1500,1);
protected function LoadChartView_viewActivateHandler(event:ViewNavigatorEvent):void {
enableClick();
}
private function startLongPressMouse(event:MouseEvent):void {
startLongPressTimer();
list.addEventListener(MouseEvent.MOUSE_MOVE, endLongPressMouse);
}
private function endLongPressMouse(event:MouseEvent):void {
stopLongPressTimer();
enableClick();
list.removeEventListener(MouseEvent.MOUSE_MOVE, endLongPressMouse);
}
private function startLongPress(event:TouchEvent):void {
startLongPressTimer();
list.addEventListener(TouchEvent.TOUCH_MOVE, endLongPress);
}
private function endLongPress(event:TouchEvent):void {
stopLongPressTimer();
enableClick();
list.removeEventListener(TouchEvent.TOUCH_MOVE, endLongPress);
}
private function startLongPressTimer():void {
longPressTimer.start();
longPressTimer.addEventListener(TimerEvent.TIMER_COMPLETE, longPressHandler);
}
protected function disableClick():void {
trace("disable click");
list.removeEventListener(MouseEvent.CLICK, regularClickHander);
}
public function enableClick():void {
list.callLater(list.addEventListener, [MouseEvent.CLICK, regularClickHander]);
}
public function resetListSelection():void {
list.selectedIndex = -1;
list.validateDisplayList();
}
private function stopLongPressTimer():void{
longPressTimer.stop();
longPressTimer.reset()
}
public function longPressHandler(event:TimerEvent):void{
disableClick();
stopLongPressTimer();
deleteAlert.addEventListener(PopUpEvent.CLOSE, popupClosedHandler);
deleteAlert.open(this, false);
PopUpManager.centerPopUp(deleteAlert);
}
public function popupClosedHandler(event:PopUpEvent):void{
if (event.commit)data.removeItemAt(list.selectedIndex);
callLater(resetListSelection);
}
我用鼠标和触摸事件进行简单的测试:
I used both the mouse and touch events for easy testing:
<s:List id="list" top="0" bottom="0" left="0" right="0"
dataProvider="{data}"
touchBegin="startLongPress(event)" touchEnd="endLongPress(event)"
mouseDown="startLongPressMouse(event)" mouseUp="endLongPressMouse(event)">
