ActionScript 3.0 :: Reference To A List's Scrollbar?
Feb 9, 2010
If I have a list component on the stage, how can I reference it's scrollbar? I mainly want to see if it's vertical scrollbar is currently visible and get the scrollbar's width.
i have created some 6 -10 buttons and i want to keep these list of buttons in the scrollbar. so that a user can view only a set of 4-5 buttons at a time.i tried out the kirupa-scrollbar but when the masking is done on set of buttons all the buttons are under mask and i am unable to click any of those .i tried the UIscrollbar component, it works for the text area but not for the buttons
I'm using the List and UIScrollBar components. I've got a list with a scrollbar placed far from it. I want to disable the built-in scrollbar in the list and scroll it with a different scrollbar. How is this possible?
I've got a List component set up but some of the text exceeds the space available and so I'm trying to add a horizontal scrollbar as well as the vertical one.In the component inspector I've set the horizontal to "on" and given it a width of 200 (my component has a width of 150).However, it cannot be scrolled and I get this error message: TypeError: Error #1009: Cannot access a property or method of a null object reference. at AWorkingFile1_fla:: Main Timeline/baseData()Is it actually possible to get the scroll bar to work?
I've got an Horizontal List. It contains 6 XML Nodes at the moment. But what I'd like to do is remove the scrollbar so that an button can function to scroll through the nodes instead.
I'm trying to make my own component that behaves like a list and supports infinite scrolling (in 1-dimension : vertical or horizontal) - both directions. For eg, a vertically laid out list which the user can scroll up or down forever - without ever hitting the 'last' or 'first' item. A good use for this: a calendar that displays each month as a list item.
Anyway, there are a bunch of things to overcome. The first of which, I think, is to disable the scrollbar's bounce effects (introduced in the latest Flex 4.5 (mobile) SDK). If I can disable the bounce effects, I'm guessing I can then add/remove items as needed to the list and it would scroll infinitely.
I need to create a scrollable list of buttons. Only vertical scrolling is enough. The main thing is that, the buttons and scroll bar should be custom drawn. One and two dimension of button layout support is needed.
I had created a loader which can load an array of images. However, when there are more images, the images actually got hidden as the size of the application is too small to accommodate all the images. I would need to create a scroll bar. I tried creating a scroll bar but there were errors faced saying that "TypeError: Error #1009: Cannot access a property or method of a null object reference.". I am not really sure on how to do it,
I am having problems with a scrollbar tween on my site. I have tested the site ([URL]) on many browsers, and it tends to work fine. But, on a Firefox browser, I think with a new version of flash player, and also when I run the Debug on Flash, I get this occasional error:
[Code]...
This tends to happen if the user clicks on the scrollbar button, begins moving the scroller, and then, without clicking back on the scrollbar button to stop it, the user presses on a button on the left navigation. I think I understand what the error is telling me, that it can't complete a function for things that are not yet on the stage. But I am not sure how to fix the code regarding the Tween to get around this. Would anyone be willing to look over my files if I sent them? Here is the Tween code I am using:
I'm having this frustrating error showing up and I have no idea why. Let me show you my classes and see if you can spot anything wrong. First, here's my ILode interface:
So the problem I'm having is the compiler is throwing that 1000: Ambiguous reference error for any reference to instance.priority or instance.label. Why??? Instance is typed to IFlexLodeInstance, and IFlexLodeInstance lists method signatures of priority and label getters, and it inherits ILode, which lists method signatures for priority and label setters. What can I do to get the compiler to stop complaining?
My code is an external .as file. Google provides this code on their demo, which contains the this keyword:
[Code]...
Notice that I have 4 calls to console.log. The first 3 fire, but after the new GATracker statement, the 4th does not fire. I have a feeling that I'm overriding the entire package with the object created from new GATracker when I should be passing a different context. I believe the correct context I should pass is whatever this defaults to when not inside of a package/external file, I assume it references the main stage object.
I'm using flex 4.1 to write an application. i read in the documents that has the rowCount property to set how many items to display. the does not have that property. how can I limit the list to display 3 items ?
I am working on an older Flash project created in CS3 ActionScript 2.0 How can I make the pointer cursor change to the hand when hover over a list item?_root.slidePanel.myList'myList' is the list. I have traced out the contents of the List MC and it has a child MC called 'content_mc'. I assumed this was the object containing all of my list items but the only members of this MC I can see (when tracing them out) are 'setRGB' and 'searchKey'.
Creating a dynamic list and associating a picture with each list item. i need the list to be scrollable, and i want the list and it's associated picture to be displayed randomly when the application is re-launched. i.e it doesnt show the same list everytime.
I also what to be able to sort the displayed list items. e.g if the list items is about restaurants, i want users to be able to sort the displayed items by either; district, cusine type and gastro type.
I have a combobox and list component on the stage. The combobox has 3 selections. How do I get it so that each selection triggers the specific xml file to load into the list component? I can't get them to communicate to each other.
The 'recommendations' dataProvider is an ArrayCollection of String, which are generally sentences about as long as this one. By setting the variableRowHeight and wordWrap properties as shown, if a sentence is too long to fit on a single line, everything works fine- the row expands and the messages show on two lines, or occasionally three.
The space allocated for this panel within the entire canvas means if the total text size of 'recommendations' exceeds six lines, I need for the entire list scroll. This is also working just fine. The trouble is when using the mouse wheel to do the scrolling- Flex scrolls both the entire list and the single item where the mouse is hovering. Often this results in only the second half of a sentence being visible. Non-programmer friends I have asked to look at this noticed this, and tell me it as a problem. If a user does not notice the dual scrolling, and sees only a fragment of a sentence, it will be perceived as an error in the application.
I want to add a SimpleButton to a list item in a list component. I am getting the CellRenderer for the list item I want and using the addChild method to add the simple button. The button appears in the right spot on the list item but it doesn't function like a button. It's like the contents of the buttons first frame is added to the CellRenderer and nothing else.
When a user selects a category from the first drop down box then i want the 2nd drop down to be updated based on the selection of the first drop down. I have created multiple ArrayCollections whose names are set to the "data" values of the first drop down, for instance:
[Bindable] public var countries:ArrayCollection = new ArrayCollection([ {label:"USA",data:"USA"},
Why I have to press 2 times the arrow key down to get a navigation through the list items in a list component of Flash?
Theres any workaround for this? I have a listener for keyboard event that checks if keyCode is equal to 40 if it is then I use 'stage.focus = list', but I have to press 2 times key arrow down to start navigating through list items.
I'm trying to animate a list as I delete the top row. All the examples I can find use itemsChangeEffect to bind to the effect, but this property exists only in MX lists, not spark lists.
Any idea how I can get the same effect done in Spark Lists?
I'm trying to remove the top most item in the list with a slight fade out effect before the rest of the items move up to replace the gap.
I am creating a map of the USA and when a user mouses over a particular state,I want to display a movie clip (which is just a text list of our dealers in that state). When the user mouses out I want the list to disappear.However, I want the user to be able to mouse over the list to scroll the list and whenever I try it, obviously the state loses focus and the MOUSE_OUT Event fires.How to I get around this?Here is the code I have currently:
The traditional way to assign an icon would be to use the icon field of the item renderer,which reads the value of "icon" property in your data, for example:
But i want the DefualtThemeLogoutIconClass to changed to another class: ightThemeLogoutIconClass when the theme is changed.The only way to do this would be to use a style declaration containing a classReference to the icon, and change its the value in each of the CSS files of the various themes.The question is, is there any way to assign this style to an icon in a List, something as easy as intuitive as list[0].getIcon().setStyle("styleName");
