I am trying to create a thumbnail viewer using a list component. I used list.cellRenderer to display a test image and it displays that image about 50 times vertically down the list component. how to use this component with images?
View 1 RepliesI am an inexperienced user of Flash CS4 Pro (v10.0.2). I am attempting to use the List component with ActionScript 3.0 to make a different image display when a user clicks each item in a list. I did find a tutorial that showed me how to make different text display using a dynamic text box and the following ActionScript:
[code]...
...where My List is the instance of the List component and ListText is the dynamix text box. In this case, the user clicks an item in the list, defined by the label value in the dataProvider parameter of the List component, and text displays as defined in the data value in the dataProvider parameter.
However, as I mentioned to start, what I really want to do is make images display instead of text. Can anyone provide me the steps to do this?
the embed fonts stuff in flash, it sometimes works and then again it does not. my problem I need to embed a greek font to be used with the List Component. what I did so far:
1. library-> new Font ( Named it myFont, exported it as:MyFont )
2. put a list comp on stage called it myList
3. got a xml file called index.xml encoded in UTF-8 (so it displays greek chars) that gets loaded (makes no diff if you use component inspector to insert the labels)
4. set system.codepage to false;
Code: Select allmyList.setStyle("embedFonts", true);
myList.setStyle("fontSize", 13);
myList.setStyle("fontFamily" , "MyFont");
what it does not work. I am at a loss as to how to get this to work. I am attaching the file and the font used. (verdana arial should work too, but even they don't embed)
Mabe it has something to do with the xml encoding, but if you try to just copy the greek characters into the component inspectors lable field they are still not displayed. So I guess xml encoding is not the problem.
i want to create a chat app using flex 4.5 mobile project for android device. For the chat screen, i wanted it to look glossy and stylish. Hence i thought i would use the list component and disable the selection in it. I m able to add the chat messages into the list. But i doubt if large chat data might hinder the performance. Im using a collection and i ve binded it with the list. Whenever i receive a chat i update the collection and it gets displayed in the list. Can someone tell me if his could pose a performance problem as list component is not intended for this purpose.

... just not all that familiar with the format of actionscript when working with objects... using CS3 and as2 btw,
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'.

View 1 RepliesWhy 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 building a top view 2D map, that it's objects are stored on the server.The kind of objects are 10 and might be a photo, label, button, lists, mix of them or labels with tooltips.The component must request the "areas" that are missing on screen.An area is 1000x1000 px and is cached in flex.To move in the map, will be like in google maps (drag-and-drop).I should be able to have another list and move objects from one to another using drag-an-drop on objects. Ex.: I grab an objects from a list and I move it on this map, I release the mouse button and the item is placed there.Now the problem is: I build a custom component for this trying to emulate the item renderer for performance and recyclage, implement drag-and-drop on objects and request the areas that are missing?
or
I extend the List component from spark and I add some features as multiple kind of itemrenderers and use recycle on them. Of course it must be able to request the missing areas on the screen and cache it's data.Maybe create a custom layout is needed too.What I need is something that must be really fluid, so the lighter this component is, the better.
UPDATE: *There will be not any object over another.
*I will not use hitTest on bitmaps because all bitmaps are wrapped in another component,as they,for now are itemrenderers.
Anyway I already begin to do this using a class that extends the SkinnableDataContainer and a custom layout. As the layout is not like a grid, is sparse, random items at diferent points(x, y).How to get the localX and localY, relative to item renderer and not to the Spark List, from a DragEvent in Flex 4?
I have two Lists (components) on stage. The first one (mainList populates from an XML called topics.xml
[Code]...
on event handler change, I want to load the second list on the other list component, called subList..It's not loading.. I believe it's because when it reads the data from my topics list, it reads topic1.xml instead of "topic1.xml" ( reads without the quotes). If I unquote line v.list.load("subtopic.xml"), it works, but I need it to be loaded from the XML..

I'm a Flex noob and I've been struggling with this problem for a last week, and I'm at my wits end.
I have opened the following XML file

<place-of-death>qwert</place-of-death>

I would be so incredibly grateful if someone could help. I am pulling out my hair!
Since my original post got moved to Components thread, but no one is responding and the majority of the people on the Forum are here, I'm gonna repost it here. I have an AS created List Component that is dynamically populated using a dataProvider populated from an XML document. When I addChild to the main timeline, everything works. When I addChild it into a MovieClip, the list shows up with the appropriate number of rows, but no text.[url]...
View 0 RepliesI would like to have a List displayed that displays data collected from the user into an ArrayCollection. I have a main DataHandling.as class that "adds" the data to the AC as an Object, but when I use trace() on the AC from another class, it does not show any values being present in the AC.
I also added some test data to make sure I was populating the AC correctly and that works just fine. I just can't seem to figure out how to add data (text specifically) to the array from another class. (The other file is .mxml)Here is my mxml code (MyCards.mxml):
ActionScript Code:
protected function myCardsList_creationCompleteHandler(event:FlexEvent):void
{
// This traces the 'cards' ArrayCollection from the other .as class
// No values are listed

I have a Flash page that goes out and reads an XML file, then displays the information in it. Most of the time, it works great. However, when it comes to nested lists, it doesn't work. I am using CDATA so that I can use HTML code to display the information as intended. But Flash absolutely refuses to display a nested list correctly. For example, if I put in there <ul><li>item 1 <ul><li>subbullet 1</li><li>subbullet 2</li></ul></li></ul>, it displays everything as if I had made each of them individual list items under one master <ul></ul>.
There's got to be a way to get Flash to understand and display a nested list. It's a simple thing to do, I know it.
I have a screen which is essentially an address screen. Amongst other fields. there are two fields on the screen which are used to enter the region of the user. One is a combo box, the other is a plain text field.
After the user selects their country from a drop down list, if that country has a list of regions associated with it, a Combobox is populated and displayed, with the text field being hidden. If there are no regions associated with the country then the combobox is hidden and the text field is displayed:

I have a List, that is not showing any items until you scroll, then the items show up. Does anyone know how to fix this? I tried calling list.invalidateDisplayList(); and list.invalidateList();

I found that if I add creationComplete="{list.dataProvider = _xmlList }" It solves the problem.
I'm working on a flash cards application and am using an ArrayCollection of Objects to store each cards individual data. When the user click the 'save' button, the text from the two textAreas and the 'title' textinput are stored in the AC as one object with .title, .side1 and .side2 properties that contain the text from the flash card. I have made a List in a separate class I want to have display the title of each card the user has created, but after days of researching and looking around, I still cannot get the display to list the titles.
Part of my NewCard.mxml:

I seem to have is that the Autocomplete component that seems to be part of flex extras is not displaying the list of items in the dropdown list. Basically, I get a list of blank items. I know they are there and they are the right items because as soon as I click on one, I get the right text in the combobox.
my Code in the mxml looks something like this
<mx:FormItem label="Company:" width="750" fontSize="20" horizontalAlign="right" color="#000000" required="true">
<ns1:AutoComplete enabled="true" labelField="CompanyName" textAlign="left" dropdownWidth="450" id="txtCompany" width="450" />
[Code]....
Again, when I type "T" in the text box I see a dropdown list with 3 empty items. Clicking on the third item puts "Test3" in the textbox. But the items themselves are not visible.
It almost as if its a font/foreground color thing, but I've played around with some of those settings too with no success.

I have an issue with Spark Lists whereby I am trying to ensure that an item is always selected and ensure that the GUI displays this to the user.
The application (full code below) creates a List, a Label and a Button. The Label states what is selected in the List. The button removes the selected item. Changing the selection, updates the text in the Label. Important: The List has "requireSelection" set to true to ensure that an item is always selected.
If I select the first item in the List, the selection is correctly reflected in the label. Clicking "Remove" removes the item and the next item is selected. This is all working correctly.[code]...
In a kind of image browser where navigation is done through keyboard's arrow keys, I get the case where the user keeps the finger pressed on the arrow key. There, the list scroll faster and the screenshot doesn't have time to draw that the next item is already called.
I can see that in that case the CPU goes from an usual 1% when browsing "gently"..to about 20% when leaving the arrow key pressed and raging through the list of images.
I was thinking to:
1) Force the scroll rate to max out at 10 items per second
or
2) Only show pictures if key downs are > 10fps
or
3) Find a function that would wait for the last image to be drawn before continuing in the list.
So, to summarize:
- how to skip drawing pictures if the list is browsed to fast...or
- how to force the script to wait for the current image to be drawn before passing to the next item...or

View 9 RepliesI have a window on my Flash stage that has some scrollable copy in it. The problem is, I can't seem to have any formatting for the text ... if I select a word or two to make bold, it all turns bold. I gather I need to use the "Display Text as HTML" checkbox and then paste in some HTML formatted text but this doesn't seem to work. I searched this forum and found that others were designating "htmlText" in Actionscript instead of just "text" ... that didn't work either. I probably just did it wrong, or maybe it's becuase I'm using the UI component "UIscrollBar" for it's scrolling of the text.
Is there anything else I need to do to be able to format some text with strong tags and maybe some href links?
I have my properties inspector with the following check marks:
Display as HTML

I need info regarding ScrollPane tool in Flash CS4. As I need to display a image in it. I have a "zoom" effect set up to where when the user pushes the + button,the x and y scale is increased. But when I does so Scroll bar does not get resized automatically. And thus due to increased size only half of the image remain visible.
