DeMonstersDebugger an update

Tiago — Tue, 17 Feb 2009 16:18:49 +0000

almost 2 weeks passed by and I saved an insane amount of time debugging my applications with DemonsterDebugger, it’s an amazing piece of work what these guys did and I’m looking forward to see more updates, as soon as I have a bit of time I will come up with a wishlist from my side, and will try to send it over to them.

What I liked most was as expected the live editing feature, you can just select a component which is completely off the stage and align it properly just with a few clicks and at the same time you can test your application by accessing functions that are not even made public.

Guys, you did a wonderful job! Thank you very much for this great app!

Flex 3: Tabbar event

Tiago — Thu, 22 Jan 2009 12:58:50 +0000

Recently while working on an AIR app, I had to create some functionality when the user clicked on a different tab, therefore I wanted to simply check for the active tab using an event. Something that I have found was that as soon as you use a viewstack as a dataprovider no events will be sent. Which led me to the conclusion that it’s not possible to track which tab the user clicked.. UNTIL I came across the ItemClickEvent which was exactly the piece that I was searching for.

How to use the ItemClickEvent

 
import mx.events.ItemClickEvent;
 
private function tabChange(e:ItemClickEvent):void{
trace(e.label); //outputs the label of the selected tab
trace(e.item); //outputs the item in the dataprovider of the selected tab
trace(e.index); // outputs the index of the selected navigation item
}

and below the mxml tag for the tabbar component

"navBar" x="10" y="125" dataProvider="viewstack1" themeColor="#648B9A"  selectedIndex="0" itemClick="tabChange(event)"/>

Actually pretty simple, but when reading throuh the docs, then you pretty quick think that it’s not possible.. although nothing is impossible

Flex teaming options

Tiago — Sun, 10 Aug 2008 22:09:05 +0000

if you are a standalone flex user you probably never noticed the option when you do a right click on a project folder inside flex, yeh there is this option called “team”,

and how useful this one is, it allows you to use a CVS repository so you can easily share and keep track of the code changes. Really really useful, but what do you do if don’t have a CVS repository? Nowadays most hosting companies offer you an SVN repository and that’s not compatible with CVS, so there is no way to use that functionality in flex right? wrong!

Since Flex3 and it’l older versions are based on the Eclipse SDK, you can install any of the extra packages that come along with Eclipse, you can download them directly from the UI by going to Help-> Software Updates ->Find & Install.

By now that should be pretty clear, you can install plugins from Eclipse directly from the UI, but you didn’t found an SVN option right? Jump right over to this site: http://www.polarion.org/index.php?page=download&project=subversive, and add the two sources download the SVN and the SVN connector, you’ll be asked to restart Flex to apply the changes, go on and do that.

As soon as Flex started again, go have a look at the team option and select Share Project now you can choose between CVS and SVN

I’ll be writing a tutorial on how to install the SVN extensions and some first steps very soon, so stay tuned for an update
