Actionscript 3 :: Keyboard Navigation In Flex Datagrid?
Aug 21, 2009
I want to implement an Excel like keyboard (arrow) navigation in an Advanced Datagrid in Flex.The docu at [URL]states that arrow keys can be used to navigate around cells. However, in my case that does not work. I can only navigate rows up and down
When focus is on the AdvancedDataGrid control:
* Use the Left, Right, Up, and Down Arrow keys to move between cells.
* Use the Shift+Home and Shift+End keys to move to the first and last column in current row.
* Cells are only selected by default, they are not editable.
* Press the F2 key to make a cell editable.

Is there a code for the tab key like works for the return key. I am using AIR to write to an excel file and need the values to go horizontally in different cells, and all i can do right now is use to get them to enter vertically. In all my searching I can only find articles about keyboard navigation regarding the tab key.

Below is the working code I have for navigating a presentation composed of multiple scenes.It works by starting a listener that waits for key presses and then jumps to the scene where the letter that was pressed is present in the first frame of the scene.Example: Press the letter C and the presentation jumps to the scene where there is a frame marker with the uppercase letter C present.
ActionScript Code:
// Begin Keyboard Navigation
// This script goes to the frame/scene-frame labeled in a single uppercase letter.

I want to create an interface navigatable through keyboard. The interface is somewhat like nested DVD menus, and it is not known in advance how many buttons there will be or where they will be placed. So for example you would be on button 1, if you press right, the closest button to the right would be selected. how would I go about enabling this? The purpose is to enable keyboard navigation for complex management screens for a game I am doing;
I would like this to be as independant and reusable as possible, which means I would like it to work with any clickable object, not just buttons, and certainly not my own custom class of buttons. This also means the buttons might be placed through the flash IDE and so placing them on a grid is not an option (I'd like this to be easy to use for non-techies).
My thinking goes like this: add all buttons to a manager, then select the first one, then on keypress, triangulate and select the closest in an angle of (+45degrees,-45degrees) of direction pressed. But it seems overkill to me, and I guess in some edge cases, some buttons will be forever unselectable.

A 3*3 grid, consisting of 9 squares (0-0, 0-1, 0-2, 1-0, 1-1, 1-2, 2-0, 2-1, 2-2). I want to be able to navigate the grid using a keyboard by going up, down, left and right. If I hit the edge of the grid, I would like to "wrap" to the other side. This kind of menu is seen on games, mobile devices etc.
Does anyone have a good implementation of navigation algorithm (does not to be in AS3), rather something I can refer to?

I am developing a website completely on Flash, it has an option for Fullscreen as well as keyboard navigation to switch between slides. On windows, when i do fullscreen, everything works fine. On Mac machines, after full-screen the keyboard navigation script stops working. This is the script I am using for keyboard action. Is there any particular script for Macs too ?
on (keyPress "<Right>") {_parent.gotoAndStop(2);}

I am new to actionscript. I was trying to make a slide show frame by frame. I have my main timeline with the following code in first frame.
stage.addEventListener(KeyboardEvent.KEY_DOWN, fl_changeSlide);
function fl_changeSlide(evt:KeyboardEvent):void{
if (evt.keyCode = 37) // LEFT{
gotoAndStop(this.currentFrame-1);
}else if (evt.keyCode == 39 || evt.keyCode == 32){
gotoAndStop(this.currentFrame+1);
}}
In the third frame I am trying to load an external swf by clicking a button 'rrbutton' and unload the same when the user clicks left arrow.
var loadit = new Loader();
function ack(evt.keyboardEvent):void {
if(evt.keyCode == 37){
loadit.unloadAndStop();
stage.addEventListener(KeyboardEvent.KEY_DOWN, fl_changeSlide);
[Code] .....
The external swf loads on clicking the button and unloads when left arrow is pressed and the main time line frame appears. But thereafter the keyboard navigation in the main timeline(through function fl_changeSlide) is not working properly.

I'm writing an application using a DataGrid DG1 in a MovieClip MC1. The User can click on DG1 and edit it, ok, no problem. But when the User begins to edit the content of a specific cell of DG1, I want to open a dedicated wizard in front of it. In the first step of that wizard popup (MovieClip MC2, child of MC1), there is another DataGrid (DG2) and I would like the User to be able to directly use the up and down keyboard arrows to browse the DG2 content without having to click it first.
But the keyboard events are then captured by DG1. I tried to use a stage.focus, setFocus, I triggered MouseEvents on DG2 but nothing to do, I have to physically click on it before the keyboard events are sent to it. So, my question is: how to, within MC1, tell Flash the keyboard events will be triggered on DG2 ? Can we ask DG1 to loose the (keyboard) focus ?

This is a snippet of code in our custom item renderer which is in actionscript:
textCustomItemRendererTempForTab.tabEnabled=true;
textCustomItemRendererTempForTab.focusEnabled=true;
textCustomItemRendererTempForTab.setFocus();
Alert.show( "Without this alert focus goes to next grid " );
keyboardEvent.preventDefault();
keyboardEvent.stopImmediatePropagation();
keyboardEvent.stopPropagation();
Right now tab navigation works (on tab, focus goes to next editable cell) with the alert inserted in the code but I'm not sure why because I believe the alert in the code breaks the flow of event bubbling. However without the alert (which is what we are going for) the focus goes to the next grid in our UI.
You can see the attempts of trying to stop the event from going to other components. I have also tried to call preventDefault() and stopPropagation() on the datagrid when it receives a tab key event.
how to allow proper tab key navigation without an alert?

I am working on a problem since a week soon, but I still couldn't make it work as expected. I have a DataGrid which has HBox with a CheckBox an a Label as itemRenderer (see Code below). When I tap in to the Cell the standard itemEditor pops up and lets you enter the content of the label. Thats the standard behavior. I works fine except for 2 problems:
If I enter to much text, the horizontal srollbar pops up, and the cell is filled with that scrollbar. As you see I tried to set the horizontalScrollPolicy to off, but that doesnt work at all... I tried to do that for all the different elements, but the failure is still existent. When I have filled more than one row, there is an other mistake happening. If I tap on a row, the datagrid selects the one below that row. That's only if one line is already selected. If I tap outside the datagrid and then, tap at any row the itemEditor of the right row will show up... Is there anything now wright in the setup of my set data method?
package components
{
import mx.containers.HBox;
import mx.controls.CheckBox;

Following are some snippets of the related code. Hope someone can spot an error in it.

For poor performance reasons, the DataGrid will cache checkboxes and reuse them for different rows. If you have 50 rows, it won't create 50 checkboxes. It will create as many checkboxes at are visible, plus a few more for padding, and then reuse them as you scroll. This is why you need to explicitly manage their state. How can improve it ? How can fixed checkbox value ? i used checkbox like below But checkbox doesnot remembering the values

I am attempting to style the headers in a flex datagrid and I keep getting the warning:
Type DataGrid in CSS selector 'DataGrid' must be qualified with a namespace
What does this mean? I have gone through a bunch of tutorials and none of them have worked. It seems like changing a the colors in a datagrid should be relatively simple.
Here is a code sample:
<mx:Style>
.headerCustomStyle
{
fontWeight: "bold";

in Flex I have something like that: [code]and dg is ALWAYS pointing at DataGrid (even if dg1 has name DataGrid_test and dg2 = DataGrid_test2) and finally action is made on my first DataGrid (DataGrid_test).[code]and search still points at ColorColumn :/ My problem is really easy- I just want to pass to search different dataGrid on each state.But still I don't understand why it doesn't work. My search function uses algorhitm Boyer-Moor for searching through dataGrid.dataProvider for some text. If it find something then it is pushed into new array and after passing whole dataProvider I colorize rows with searched word.

I have 2 scenes. In both scenes, I have a movie clip that moves via keyboard control. If the goto next scene is triggered by the movie clip in the first scene the keyboard control works in the second. However, if I use a button to move to the next scene then there isn't any control over the movieclip in that scene. I've traced the keyCode in the second scene and it is picked up but the switch statement doesn't run. I'm migrating to Actionscript 3.0 and updating something I created in 2.0. I would like to do it without writing a class.

In my application, when I have got an modal window with tab navigation enabled for all the fields. When I am working with chrome, the navigation works fine but when i try it in IE, when i press on tab from the last field, instead of going to the first field, the control goes to the address bar. Does anyone know how to rectify this issue? Is it possible to set next-navigable-item on items?

I'd like to tell if a certain key is being held down around the startup of my AIR (desktop) application, and I'd like to tell if a specific key (ALT in this case) is being held down. Unfortunately, flex seems to be so event based that there is no way poll the keyboard directly. Can anyone verify this?
I know that it's possible to take the keyboard events and keep track manually. However, this won't work if the user presses the key right before startup, so it isn't a solution for my specific problem.

I'd like to arrange things so that I have a chain of keyboard event handlers in my flex application, all of whom are queried when key down events occur. Basically, when a visual component is on screen, it is a candidate for handling a key press event. Something like this (clearly this is pseudocode):
<application handles_keys="F5, F6">
<tabGroup>
<tab1 handles_keys="pgup, pgdn">
<control handles_keys="0,1,2,3,4,5,6,7,8,9" />
[code]...
I have a class written that will respond to the key events the way I want it to, so how do I register one or more instances of this class to have the results I want? Also, note that there are some situations where this class should receive events that would ordinarily be handled by a UI component. The TAB key is the main example; I have a few cases where I want my key down event handler to fire even when the focus is on a text field.
