A list of images that gives a smooth scrolling perception.

Way back when I built this:
http://www.axelscript.com/2008/09/25/building-a-simple-slider-component/

Its a simple proof of concept of how to slide some components.

This new one is built with flex for and uses a horizontal list, with HorizontalLayout to just slide the list left and right.

Notice it doesnt work by default?

use hasFocusableChildren=”true”

Controlling the soft keyboard “softKeyboard” in flex mobile.

Regex’s
http://oreilly.com/flex/excerpts/flex-4-cookbook/validation-formatting-regular-expressions.html

the problem is that mobile device hardware isn’t anywhere near desktop or laptop speeds…

I’m using an ipad2 developing a app that has a ton of screens on it, and a popup with about 20 more screens, that all have lists, buttons, and link to other popups.

Its said that you can use itemCreationPolicy=’deferred’ and itemDestructionPolicy=’never’, and then the item will stay in memory…

I’m finding that this works like shit….

example…

example not usable, its partial:

<s:ButtonBar
id="tabBar"
width="100%"
change="tabBar_changeHandler(event)"
styleName="ifButtonBar"
requireSelection="true"
height="48"
>

etc...

If you sub components are heavy that your trying to include in those states, you get a lag when clicking on them, and off of them, even after they are created once…

the fix…

NOTE: As long as your components that your trying to include in your states are spark.View components your good to use this. (its easy to convert almost any container to a view, with the “< layout >” attribute.)

use creationPolicy=”none”, then use visibility… visible.STATE_NAME=”true” show=”itemShowHandler(event)” then on show, use createDeferredContent()

NOTE: typically the first component in the views you DONT want to turn creationPolicy to none… you want to leave it default.

example not usable, its partial:


<fx:Script>
<![CDATA[

etc...

comments or email with questions.

REMEMBER TO SET

requireSelection=”true”

on a ButtonBar

var systemManager:SystemManager = FlexGlobals.topLevelApplication.systemManager
var popupStatus:* = systemManager.popUpChildren.getChildByName( 'popupStatus' );

if( popupStatus )
{
PopUpManager.removePopUp( popupStatus );
}

good for a little quick cleanup.

I use this jsut for a quick cleanup of a file, if i download it, or find source code online I want to use… its a nice quick way to get the code fairly readable to my eyes.

use Import (2) and copy and paste the settings below in the Flex Formatter.

So my good friend John Yanarella, and fellow flexer, made a great library! full of awesome utils… he’s planning on blogging about it, so i’ll just throw the link out there…

one of the coolest and most useful ones that i’ll probably use every day is IterableUtil… he’s got a great generic and reusable getItemById() function that will search child objects, and even can resolve .notation as sub proberties and child names… its pretty sweet.

You should be able to listen to events at the phone level… and intercept them… like a before and after event for each event that actually happens…

the biggest ones I can think of are

BEFORE_SMS_MESSAGE, AFTER_SMS_MESSAGE

BEFORE_PHONECALL, AFTER_PHONECALL, BEFORE_ENDCALL, AFTER_ENDCALL…

all of these could be used to log… or to fillter, or to add to your own application…

there are some requests out there for text and call blockers / filtering, and there are already some apps out there that do it, but I was just wondering CAN YOU EVEN DO THIS IN AIR?

as far as i know you can’t do this in air…

YOU SHOULD ALSO HAVE ACCESS TO THE NATIVE MENU WHERE THE BATTER ICONS SIT… a lot of apps add custom icons up there to show you things… can you do that in air either? it would be awesome!

thanks.

Just published on the android market, built using AIR, and flex 4.5.

The application is used as car dyno, and gives you the following:

0-10, 0-20, 0-30……. 0-100 times

60ft, 330ft, 1/8 mile, 1000ft, 1/4mile times…

it has a GPS Mode that lets slower cars run as well, ( they have trouble triggering the accelerometer ).

search it up, called “AXJDyno”

they were down 14 – 19… all they needed was a touchdown and to hold out the rest of the game… just a little under two minutes left!

they receive the kick off and start the drive, and drive it down the field looking like a completely different offense, and get up to somewhere around the 40, and throw up a pass to CALVIN JOHNSON #81… and he brings in the catch, and gets not one, not two, but then almost a half third before falling to the ground on his ass… then being absolutely thrilled that he had just pretty much won the game for them… he pushes the ball to the ground and gets up and runs celebrating!!!!

the refs ruled this an INCOMPLETE PASS!!!!!!!!!!!!!!! due to him letting go of the ball as he got up and ran to celebrate!!!!

SUCH F*ING BULLLLLLLLLLLLLLLLLLL!!!!!!!!!!!!!!!!!!

Step 2: Implementing Bezier Curve over the Application Background Skin
Now that you have your application background working, we can work on adding a layer on top of this. We will be adding a shape with a Cubic Bezier curve for a bottom border on top of the background creating a banner. To ensure that our Bezier curve is visible, we need to place it on top of the background (beneath the Rectangle in our code). s:Path is used to be given data to create a shape. Inside of the data property is where we define our shape. First off we have to set the data cursor to start at the X and Y values of 0,0 which would be the top left of the application. Now we make a line from 0,0 to 600,0 by using “l 600,0”. “l” stands for line. It is important to remember that these coordinates are based off of 0,0 being the last coordinates you left off on, not 0,0 being the top left of the application. Next, we need to create the rightmost border of our shape using 0,100. Again, think of this as saying, move horizontally from this location 0 pixels, move vertically from this location 100 pixels.

Now we are to the cubic Bezier curve. This part is a little tricky. To create a cubic Bezier curve and utilize control points, we use “c”. This takes 6 parameters, but you need to think of them as pairs, so three pairs of xy values. The last pair is the destination, so that part is easy. We will want our curve to reach the left side of the application, so the x value is -800, but we want our curve to end up a little lower on the left side, so we will give it a value of 50. The first two pairs are control points. Remember that our cursor is currently at the bottom right of our shape (800,100 in relation to the application). We now need to draw our curving line 300 pixels to the left, but up about 25 pixels. We do this by making our first control point -300, -25. Next we would like to draw our curving line 300 pixels to the left, but up about 50 pixels. We do this by making our other control point -300, 50. We already have our last coordinates set at -800,50. Our finished code for our cubic Bezier curve is, c -300 -25 -300 50 -800 50. To close up the left border of our shape all we have to do is use z which closes our path.

Finally, now that we have our shape, all we have to do is fill it. Just like the last step, we use s:Fill and inside of that we use s:RadialGradient to specify how to fill and s:GradientEntry to specify the colors.

I’m writing this post in regards to skinning in Flex 4 for people who are just starting Flex 4. Skinning is a very important part of Flex 4 and it will come up in pretty much every project that you make.

Step 1: Creating an Application Background Skin
First, you need to create the component. I like to put all of my skins in the same folder, so I created a skins folder. Right click on your folder and select New – MXML Skin. Name your skin, and make sure to specify the host component. In our case it will be “spark.components.Application”. Hit Finish, and this will give you the bare bones of your skin and include the states based on your host component. Since our host component is an Application, the only states we are given are disabled and normal. If we had specified our host component to Button, for example, we would be given the disabled, down, over, and up states.

Next we will be creating the first layer of our skin. It is important to remember that skins are based on layers and each layer you create will cover the one before it (the layer at the bottom of your code is the top layer). We will be using to cover the entire background which is a rectangle. Inside of this, we will use to fill the rectangle. Inside of the fill, we specify how we would like to fill the rectangle. In our example we are using a radial (circular) gradient, but we also could have used a linear gradient, solid color, etc. Inside of we specify the which are the two colors that are blended together. The first gradient entry is the color inside the radial, and the second gradient entry is outside.
Now that we have the Application Background Skin, we have to refer to it inside of our application declaration. You do this by using “skinClass” and referring to the skin file. Ex: skinClass=”com.skins.ApplicationBackgroundSkin”. Now you have a skin for the background of your application.

Its funny when you deal with graphic designers, and the hell they tend to put you through to make your application look good… but in the end it always gives me something to write about and keeps me working so its all good…

Flex 4, I’ve heard fixes the MultiLine Button issue fairly easily (I’ve heard) but I ran into the issue where the button not only needed to be multiline but also needed to be different font styles within the text…

The easiest way I could imagine would be to use the htmlText property of the flex 3, so after reading up on flex 4 and the changes to some of the base text classes, I decided to use the RichText component in flex.  That way I can use the new text stuff they added.

Here is my example, and please don’t hesitate to call me stupid… Flex 4 just got released, and I took no time to mess with the beta (busy working) and so now I get to write up on the stuff I encounter.
