Flex :: Calculate Absolute Height Of Dropdown?
Apr 5, 2012
I have many dropdowns in my flex application. Now I want to set rowCount property so that as many rows as possible so there is less scrolling when see the dropdown items.The flex application was running on a popup window. So I think I have to know the distance from dropdown to bottom border of window, and then calculate what number should be for the rowCount. Like Height/per row height.As I known, the dropdown.y is the relative y coordinate of itself. But my dropdown has many parent UI layout component, and also I have many dropdowns, it is hard to calculate one by one.

I am using the AutoComplete component in my Flex website. Everything is fine, but there is one issue. If I type something in the text area, and the items that are searched are alot, i want to increase the height of the dropdown box.
Below is the code to my autocomplete
<auto:AutoComplete borderStyle="none" id="txt_global_search"
textAlign="left" prompt="Search Content"
dataProvider="{global_search_list}"
allowEditingNewValues="true" allowMultipleSelection="true" allowNewValues="true"
backspaceAction="remove"

I have three datagrids inside VBox container. Since I don't want scrollbar in my flex widget i am increasing the height of SWF through javascript, which increases with each addition of row in my datagrid. My query is how can I get the exact height of my VBox which is the parent element of datagrid. I am not able to get the height of VBox. I have tried to use measuredHeight,height with no success.

I am tweeing a bunch of rectangles randomly on stage.
Code:
TweenLite.to(thumbArr[i],1,{
x:Math.random () * (stage.stageWidth - thumbArr[i].width),
y:Math.random () * (stage.stageHeight - thumbArr[i].height),
rotation: Math.random () * (60) - 30});
the problem is that after I added random rotation (between -30 and 30 degrees), the corners of my rectangles are still sticking out of the stage at the end of the tween.
If I trace objects width and height after the rotation I get the new values but this still doesnt help me because I am tweening to that rotation.
Code:
mc.rotation = 20;
trace(mc.width);
trace(mc.height);

I am tweeing a bunch of rectangular shaped objects randomly on stage.
Code:
TweenLite.to(thumbArr[i],1,{
x:Math.random () * (stage.stageWidth - thumbArr[i].width),
y:Math.random () * (stage.stageHeight - thumbArr[i].height),
rotation: Math.random () * (60) - 30});
the problem is that after I added a random rotation between -30 & 30 degrees they still stick out of the stage a little.how could I calculate width & height of the these objects based on their final rotation so they dont stick out of the stage?

I am working on a 3d zoom function. How can I calculate it it best? I have a placeholder_mc:
width: 400
height:400
_x:0
_y:0
In the placeholder_mc I have 10 obj_mc's:
orig width:400, scaled in placeholder_mc: _xscale=20
orig height:400, scaled in placeholder_mc: _yscale=20
the _x and _y are random positions
Now I need a formula that make the placeholder_mc zoom into obj_mc inside and the placeholder_mc must be _xscaled, _yscaled so that the width and height of the clicked _mc are exactly 400x400.
for the _x and _y I use.. onEnterframe=
placeholder_mc._x=placeholder_mc._x+(placeholder_m c.obj_mc._x-placeholder_mc._x)/8;
placeholder_mc._y=placeholder_mc._y+(placeholder_m c.obj_mc._y-placeholder_mc._y)/8;
So this makes the placeholder_mc move to the correct position of the clicked object but how can I scale it now the placeholder_mc so that he moves and scales correct?

On my website, I display uploaded PDF files in a flash player for my users to read. I already use various tools to extract the text and produce a serious of high quality images from the file and the system works well. The last piece of the puzzle is to be able to highlight specific parts of the document to help users with accessibility issues.
However I cannot figure out how to calculate where the specific text is positioned on the page? Notes: The documents uploaded to the system are from 3rd parties, so fonts may be embedded. Meaning that I cannot be sure of the width of specific letters. The text to be highlighted may not be unique, the same text may be repeated How can I calculate the coordinates, height and width of a specific piece of text on a PDF, so that I can then draw a box around it?

I looked around, and the latest reference I saw was from 2008 stating that the standard FileReference browser does not support retrieving the user's file's absolute local path unless it's an AIR app, and indeed there's nothing in the docs suggesting otherwise. The reasoning behind this is apparently some misguided security concern... I get it's not a great idea to let any Flash app know your directory structure, but if the user actually grants your app a file, I think it doesn't invalidate the security model to know just that file's absolute path.
I'm wondering if the state of things has changed at all with Flex 4 and there's a method of getting the local filename of anything. I need it because I'm making an application that when distributed runs locally in 99% of cases, so doing a full file upload just to save it somewhere else on the local machine seems silly. (Plus the standard file uploading method doesn't support SOAP, which is what I'm using for all my other services...)

I want to constrain the height of a flex component to the height of the browser viewport.
The component's children are populated from a database table using a repeater, and are basic checkboxes. There are enough of them that the flex app ends up being about twice the height of the screen, which means some of the rest of the layout goes crappy on me. How can I force the component that contains these to limit itself to the size of the viewport?

How to set a Spark List height to the height of its content?Tried this:
var lastRow:IVisualElement =
myList.dataGroup.getElementAt(myList.dataGroup.numElements - 1);
myList.height = lastRow.y + lastRow.height;
It works in case of a single item, but lastRow is null in case of more items.

By default the height of an Flex Accordion container is the height of the initially selected child. I'd like to be able to set the height to the tallest child so that no resizing or scrolling is necessary when other children are selected. I do not want to use the resizeToContent property. I want the size of the container to stay constant no matter what child is selected.
My current thought is to extend the accordion class setting the creation policy to "all" and then override the measure function to loop through all the children and find the tallest one and use that for the height. This seems a little kludgy though, so I'd like to know if there is a better approach. Ultimately my question is: is there a way to set the size of an accordion container such that the container never resizes and scoll bars are never necessary to display any of the children?

I am working with Flex, and I need to take a relative URL source property and convert it to an absolute URL before loading it.
The specific case I am working with involves tweaking SoundEffect's load method. I need to determine if a file will be loaded from the local file system or over the network from looking at the source property, and the easiest way I've found to do this is to generate the absolute URL.
I'm having trouble generating the absolute URL for sound effect in particular. Here were my initial thoughts, which haven't worked.
Look for the DisplayObject that the Sound Effect targets, and use its loaderInfo property. The target is null when the SoundEffect loads, so this doesn't work.
Look at FlexGlobals.topLevelApplication, at the url or loaderInfo properties. Neither of these are set, however. Look at the FlexGlobals.topLevelApplication.systemManager.loaderInfo. This was also not set.
The SoundEffect.as code basically boils down to
var url:String = "mySound.mp3";
/*>> I'd like to convert the URL to absolute form here and tweak it as necessary <<*/
var req:URLRequest = new URLRequest(url);
var loader:Loader = new Loader();
loader.load(req);
I would also be perfectly satisfied with some way to tell whether the url will be loaded from the local file system or over the network. Looking at an absolute URL it would just be easy to look at the prefix, like file:// or http://.

I am going to embed a Flex app on an html page. The html page is already going to have a scroll bar to scroll up and down. The contents of the flex app are very dynamic, and I don't want to have an extra scroll bar when there is already one. So is there a way to make the height of the swf match the height of the contents of the swf?

My Dataprovider for a grid is an arrayCollection which is dynamically loaded with Objects . for example : a person object with persionID,PersonName ..etc . I applied a filter function on my dataprovider based on personID . below is my function
public function FilterFunc(item:Object):Boolean
{
var same:Boolean=String(item.personID ) == filterpersonID ;
return same;
[Code]....
this function is called whenever a new object is being added to the arraycollection . The problem now is dp.length in the above function is returning only the no of objects of the particular personID on which the filterFunction was applied instead of the absolute value . Its not limiting the size of the other objects which are runnning into thousand's causing memory issues . once i change the filterFunction to different personID , it slowly starts limiting the respective personID objects. So the sizeHandler() limits only the personID objects for which filterfunction was applied instead of the whole objects , this is the problem .

I'm having with a menu navigation system. I'm using Flash MX. I have created a menu system for the site I'm building ([URL]) where one of the buttons "Choose photographer" drops down a list of names. All the other buttons just jump to another page. The drop down is currently using tweens also the logo moves to the left as the dropdown appears and returns when the dropdown returns. All working fine apart from its a bit jerky.
It's I just wanted to get away from tweening and use action scripts instead, as I'm a newbie to all things Flash I trawled the net for tutorials and examples so that I could cobble together the exact same effect. I have managed to get the drop down work and return using the action script and it does seem smoother and works slightly better. But can I get the logo to move to the left and back in time with the drop down...no.

Short version: ComboBox's dropdown works and renders properly before fullscreen, but not during or after. I'm not totally sure how to ask this, so I've actually made a page demonstrating the error, with a very simple Flex app, and all three directions you need to experience the problem yourself.
For those of you not daring enough to follow my link above, I'll do my best to explain here. I've built a rather extensive Flex application (not the one in the link) that has some graphs and charts and checkboxes and other controls for those charts. At the bottom of app in a few of the application States, there is a ComboBox (like a <select> tag in HTML). Because this is at the very bottom, when you click it to access it's dropdown menu, Flex thoughtfully has it come out of the top.

We are rewriting our multiscreen game from Flex Project to ActionScript Mobile Project (root object is flash.display.Sprite and not spark.components.Application). Aim is to increase performance on tablets and have better overview what exactly is going on, what listeners are added and so. (I just don't trust Flex in this.). Do you know any alternative for DropDownList and/or DataGrid? I can't use MinimalComps, because there are little options to customize.

I'm creating a webpage, and I have made some buttons.Image 1 is the homepage, which is frame 1 in Flash.Image 2 shows that when I rollover the button "Portfolio,"I get a dropdown menu.I have this set as frame 3 in Flash.Image 3 shows that I've gone down the dropdown menu and rolled over "Photography." But if I rollout of any of the things from the dropdown menu, it stays at Image 2 (Frame 3)with the dropdown menu visible. Which is a problem...I want to be able to rollout of these buttons to revert back to the homepage, Image 1 (Frame 1).But, for instance, telling "Graphic Design" to go to Frame 1 on rollout means that if I try to go below "Graphic Design" to "Photography," I've rolled out--and so the rest of the menu disappears.So I want to roll be able to select anything from the dropdown menu, and only rollout to Frame 1 if I go outside the entire dropdown menu, not just one button.

Background: I am doing some UI work where I allow the user to programatically add and resize controls on a canvas. Problem: When resizing a combo box through AS the dropdown stays at the same width as the first time it drops down. So user places combo box on the page, clicks the down arrow, sees the options, selects an option or clicks down arrow again to close, resizes the width of the drop down, clicks the down arrow. Now drop down is the same width as original. Have tried simple things like setting the width of the dropdown specifically and invalidating display list but it still doesn't work.

Trying to add handling for when the selected item changes in a drop-down. However, the Change/Changing events are fired before the drop down panel closes. This is too soon. I need to do some handling after the drop down is closed with the new selected value.

I have this datagrid which has columns with a NumericStepper as an itemEditor where the user can change the number of items he wants to buy. How can I calculate the sum of all cells when the user updates datagrid's values?
EDIT 1
My datagrid is about colors and sizes of a product. The columns are generated dynamically from this function
private function getColumn(dataField:String, headerText:String,editable:Boolean) : DataGridColumn
{
var column:DataGridColumn = new DataGridColumn(dataField);
[Code]....
the row.size28 is generated dynamically. So it could be row.size29,row.size30 etc.
How can I loop through all my cells without knowing their data.property?
