I have I datagrid, on which I want to select multiple rows on a other user interaction than the one intended by the Programm. I'm wondering, whether I can programmatically select some rows depending only on code?

I have a question I came up with 3 days ago about how to do the blue underlining of a datagrid row programmatically. I thought to have found the solution, with just adding the column and row Indexes to the datagrids editedItemPosition Property.It turned out, that this is just practical if you want to be able to edit the grids row right away. But what if I just want to underline it with the blue color?Additionally how to detect that a list based Item got this kind of selection? es there a event to detect that? whats the name of this kind of selection?
View 1 RepliesI have two datagrids which should do everything synchronic except the data entry. I already managed to make them scroll synchronic by using the scroll event. My question is now how to select a item of a datagrid only programmatically, and how to get the mouseover effect and underlining the corresponding row with a bright blue color?

View 1 RepliesIn a spark list I could use the change event to find out which item has been selected or deselected. The dispatched IndexChangeEvent object has the properties newIndex and oldIndex holding this information.
But with multiple selection allowed this doesn't work anymore because newIndex and oldIndex could refer to indices of still selected elements.
A solution would be to copy the selectedIndices vector to another variable and compare this variable with selectedIndices after a change in selection, but this seems to be somewhat complex.
Does anyone know if there is an easy way two get the index/item a user is deselecting while other elements are still selected?
I've two problems, the second of which is only an issue because it's a possible way to fix the first! I'm developing a Flex 4.1 application, using a Spark theme: I can't change these; Halo isn't an option. It's providing the facility to fill multiple-selected cells of an AdvancedDataGrid with a single character, from a single keypress. So the user selects their cells using the Shift key, hits H (for example) and sees all the cells update with H, without using an itemEditor but via grid keyDown events instead. Then they click somewhere else and the selection should clear.
However the visible selection isn't fully cleared and the newly coloured cells won't all change from their selected colour. Underneath I can verify that the selection has cleared: mygrid.selectedCells is empty. All behaviour afterwards points to some kind of display glitch with the grid: The cells aren't selected any more but they look like they are.

I have a populated list component with multiple selection enabled, on pressing a button i want to know all of the selections that have been selected. Instead i can only find the .getSelectedItem() thing, which only tells me the last selected thing. How would i do what i want to do?
Also, another thing. If i want to select a specific index of the list, how do i do that? I have tried
'_root.roomsAvailableList.index(i).label'
'_root.roomsAvailableList(i).label'
etc. non seem to work.
In Flash CS3 is there any way to scale a large number of symbols (each on their own layer) at the same time, about each symbols own center. For example after scaling down, every symbol is smaller but it's x,y position has not changed.
View 1 RepliesI've added checkboxes to a list component using the cellrenderer however the behavior is different from what i expected. I'm only able to check one box in the list at a time. I need to be able to check mutiple boxes in the list.
I'm aware you could hold down the control key and select individual the checkboxes, but the application i'm developing is a touch screen aplication hence no keyboard, no control key. I've tried programmaticaly setting the selectedindicies but the checkboxes don't appear checked after the selectedindices have been set.
I have a spark skinnable component which contains a datagroup with images. The datagroup is scrolled by hovering the mouse over it. Everything works fine except one thing: after I change the datagroup provider, I need to scroll down automatically. The problem is the images are not loaded immediately after I set the provider so (contentHeight - height) does not yet represent the actual maximum scrolling position. Is there an easy way of telling the datagroup to scroll down as its content loads? Because the workaround seems to be not so straightforward. This is the code for scrolling(thumbnailStrip is my datagroup):

I never realized that fl.getDocumentDOM().selection doesn't retain the selection order... <sniff>. I was hoping to build relationships based on the order. I guess I took if for granted that tools like Maya and Max store the selection buffer in order of what was selected. I'm trying to avoid: Select Object, <Press 'Parent' Button>, Select Parent, <Press 'Parent' Button>
View 2 RepliesI'm using a dateField component (with editable = true) as an itemEditor in a dataGrid. Interestingly, when editing the textInput part of the dateField it doesn't seem to react to an ESC keydown as I would expect, i.e. reload old dateField value and give up focus. This seems to be standard for most other components, but not for as most other components do.
How would you go about implementing such behavior? I can listen to keydown == escape on the TextInput portion, but just realized that I don't know how to tell dateField to give up focus and politely close - in fact I'm not even sure that's the right strategy (maybe I should work at the DataGrid level?
i am attaching a number of _mc (my_mc) with a for loop. Inside each my_mc is an input textfield (my_txt)I want to click on my_mc.my_txt and select the textfield .the following code allow this and i can enter text from the keyboard however I want to add text from a _mc keybooard on screen (here called myBtn_mc).As soon as I click on myBtn_mc of course I lose focus ... i have tried to use a variable (select) to keep scope&focus
View 6 RepliesI have a TabNavigator, and each tab is a Module. One of the modules is labelled Units and the full code of the module is posted in this post. There are several problems:
1) Forms are not populated with data from the datagrid selection.
2) Selecting a row and clicking delete gives the very-common error: TypeError: Error #1009: Cannot access a property or method of a null object reference.
A trace on the valueObject unit within the selectionChangeHandler function gives NULL. Why? Note: In other modules (other tabs of the TabNavigator), I have DropDownLists populated with units. This means that the valueObject Unit is defined in the other modules. However, valueObjects should be private to modules, and not shared.

I need to load several images as Bitmap or BitmapData objects. The images are hosted outside the Flex project, and they're referenced by an external configuration file, so I can't embed them. Because the images won't be displayed directly to the user (they're being added to a PDF that is generated for download), creating a grouping of Image objects, attaching them to the application, and waiting for their LoadComplete handler to fire seems inefficient.
What is the best way to load these images into an application? Programatically load images in it?

View 2 RepliesI would like to know the correct way to close an AIR application programmatically. In my Spark WindowedApplication I have:this.addEventListener( Event.CLOSING, shutdownApp );and of course an implementation of the shutdownApp method (which basically tidies up temporary files).his works fine for the top-right close button of the window. However I also have functionality which needs to shutdown the application. Within the code I have called:NativeApplication.nativeApplication.exit();However this doesn't trigger the Event.CLOSING method, and so my temporary files are not cleared up. Should I not be calling nativeApplication.exit ? If so, what should I call instead? I'd rather not have to call my shutdownApp method before the NativeApplication.exit() as this doesn't feel quite so elegant.

I have various components that are skinned through a programmatic skin. The skin class references a singleton class that holds various colors to be applied to different aspects of the component. The singleton class has default colors set to variations of black/grey etc. I'm loading in custom colors from an XML file that are then loaded into the singleton. I'm applying the custom skin through a css stylesheet that is included in the main Application mxml.
The problem is that when the swf initially loads, the components that are drawn on screen are black and don't reflect the changes in color loaded from the XML file. I have some dropdown windows that show on button clicks and those dropdowns do reflect the correct colors from the XML file. Therefore, the system is working correctly, but the initial drawing of components obviously happens before the XML is loaded and applied to the singleton.
My question is, is there a way to apply a skin to an element programmatically by calling the constructor?
I have this in my css file:
.PanControlsBackground {
borderSkin:ClassReference('skins.buttons.PanControlsBackground');
}
[Code]....
or something to that effect? This way, I can remove the loading of the skins in the css file and control when they are instantiated to ensure that the correct colors are applied before displaying the various components.
I need to programmatically add a set of controls with some amount of pixels between them. I can't seem to find how to do this in the Flex docs.
View 4 RepliesIn Flex you can stream microphone audio to an FMS/Red5 server using NetStream.attachAudio, which requires a Microphone object. Is it possible to stream audio through the NetStream from somewhere other than a Microphone? For example, from a file/embedded resource?

I created an application as part of an ASP.NET site. I would like to receive error notifications in my inbox whenever something goes wrong with that flash application.As I do not have control over our mail server (which has a different domain name), I cannot establish a cross domain policy allowing me to send error emails to my inbox.Instead, thought I'd send a request to an ASP.NET handler that sends an email on behalf of the flash app.Now the problem: the error report should include a screenshot of the flash application at the time the error occurred. The FileReference class however only allows file uploads with user interaction (browse dialog) and cannot be used programmatically to send the screenshot to my ASP.NET handler. The plain old POST back only allows files up to ~200K.

How to programmatically enlarge a flex 3 button's hitArea. Is there some function that I can override? There is no function in the button class called hitArea. What I have done is, I have created a programmaticskin for a button. The form of the skin consists out four arrows. In between the arrows there is nothing (meaning transparent). Because of the way the skin is shaped, it's difficult to click on the button. The skin has alter the buttons hitArea. What I'm looking for is a way to enlarge the hitArea and alter the hitArea shape in to an square. (the hit area must ofcourse still be invisible).
