Actionscript 3 :: Dragging Items Within A Scrollpane?
Apr 18, 2011
I'm using the Flash ScrollPane component to hold a vertical stack of movieclips. I have implemented functionality to allow the user to drag and drop these movieclips up and down within the vertical stack so they can rearrange the order. My problem occurs when the user drags a movieclip towards the bottom of the scrollpane, I want the content to scroll so the user can drop the dragged movieclip below items which don't fit within the viewiable area of the scrollpane.
I attempted to automatically scroll the pane by incrementing the verticalScrollPosition when the dragged movieclip is towards the bottom of the pane, but this doesn't work as the dragged movieclip is part of the content of the scrollpane and gets moved with the rest of the content. The dragged movieclip moves up with the rest of the content and is no longer under the users cursor:
private function onDragged (e : Event) : void {
var draggedY : Number = ComponentHolder(e.currentTarget).y;
if(draggedY > this.height - 30 && draggedY > this.height - 25){
Im trying to make a flash map game.Now i have got items in a Movieclip and want this Movieclip into a scrollpane component but i have got probs cause the dragging dont go outside of the scrollpane.
Here is my Code
container.mc_item.buttonMode = true; container.mc_item.addEventListener(MouseEvent.MOUSE_DOWN, onDown); function onDown(event:MouseEvent):void {
I need t draw a rectangle on a movie clip(board_mc) by dragging mouse over it......It works fine till here but I want to put the movie clip(board_mc) in scrollpane. but after doing so the code doesnot work....can u plz guide me how to make this code work after placing the movie clip (board_mc) in scrollpane(say board_scp).
I know I'm using an older version of Flash (still using Professional 8) but I'm wondering if it's possible to have items be able to be more interactive in that the user can select an item with their mouse and drag it over another item and drop it on there.
how would you prevent dragging for some items of your List or DataGrid?
Let's say I had a list with two items: 'Tom' and 'Jerry'. Only 'Tom' should be dragable, not 'Jerry'.
Ideally I had a 'isDragEnabled(item:Object):Boolean' function, which is being queried by the drag source.
My difficulties start with the fact that the 'dragStart' event handler has a null value for the dragSource, so right from the start I find it hard to find out what the drag-start is about..
PS There have been a few discussions on preventing or canceling a drop, but I haven't seen much about preventing the drag start, hence this question.
I have a MovieClip inside a ScrollPane. Inside this MovieClip i have buttons. What i want to know is: how to click a button inside a Movie Clip, that is inside a scrollpane, and make it load a swf outside the scrollpane?
I have a project underway where I am making an interactive game. It is a personal character creator game and I need Actionscript 3 help with this.Something similar here:http:[url].... I have tried already with toggling visibility and 'gotoAndStop()' to make items appear over other items when the corresponding button is pressed, for example, when the user tries out different pants/shirts on their character.
I'm creating a facebook application in flex. I'm actually working on the friends component that shows your friends who are using the application. now, each friend has a profile image.
I created the component using a s:List element.
In the Skin Class of the element i configured the requestedColumnCount to 3, which means it shows 3 friends. i added buttons to scroll left and right in the list.
Whenever I scroll to see a different friend, for a half of a second i see no image because the List component is loading the image in order to view it.
is there a way to make the list preload all the elements so i won't have this kind of problem ?
im having some dificulties in the combobox of Flex 3, after defining the dataProvider and filling the combobox, how can i remove the items in the combobox later (without removing items in the dataprovider)? if i set the provider to "" or null, the items in the combobox are still there
how to get my CollectionEvent to work, and I seem to be able to see the problem, but I am not sure how to get it to work properly.
In my actionscript, it seems to only tell that event.items.length is 1, while I am calling my array collection from the HTTPService, and I have tested the length of my Array Collection, which seems to be accurate. What I tried to do is to use that number in the CollectionEvent function, but that does not work at all.
Attach Code
private function onChange(event:CollectionEvent):void{ for (var i:int=0; i< event.items.length; i++) { Alert.show(event.items.length.toString()); //This always gives me 1 when I have 12 items
I have placed TextFileds inside TileList Compontent. When i try to select the TextField it can't show the selected Textfield in the TileList items by default the TileList items are selected.Finally i need to select the TextFields.
Here is my code:
import fl.controls.TileList; import fl.data.DataProvider; import flash.display.Sprite; import flash.events.Event; function TileListExample() { var dp:DataProvider = new DataProvider(); var totalEntries:uint = 3; var i:uint; for(i=0; i<totalEntries; i++) { dp.addItem( { source:getTf(), scaleContent:false}
I want to if I can set a variable with the mc's name that the mc I'm dragging around hits.I did this before with eval() in as2 but there is not such a thing anymore. [code]...
I am looking for a way to "drag" several movieclips at a time and thereby create a panning effect on the entire stage. The movieclips are supposed to follow the cursor (a mask) on the X axis.
I can start dragging the symbol no problem but no amount of clicking will get it to stop. Am I doing something wrong? Using Flash CS4 with ActionScript 3.
so I am trying to drag around some images in a canvas. I am adding eventlisteners to the components and calling startDrag() and stopDrag() to pick them up and stuff:
The problem is that it is selecting the image at its (0,0) location and not where I initially click on it. So there's a sudden "jump" when I click on the image. It is not smooth.
I noticed that startDrag() has two default parameters, one of them is lockCenter and it is default to false. Maybe do I set it equal to true somehow? (I don't know how to pass arguments to my second parameter in addeventlistener)
Another question: if I want to add more conditions to it, like make a new function that uses component.startDrag(), how do I pass the component to this function while adding event listener to it at the same time? for example: I want to do:
I have a flash project with three non overlapping panels (visual spaces) each of which contains different movie-clips. Each movie-clip in a particular panel is the child of that panel.Now, I want to drag one of the movie-clips from one panel to another (remove it as a child from the first panel and add it to the other) without a jitter and proper drag.What is the appropriate way to handle the drag architecturally
