Flex Effects Example in a ViewStack
February 16, 2009
Since Adobe got a hold of Macromedia, they had Flash in their arsenal. And when you are using Flash, you have the ability to create cool, smooth animations. Using that technology, Adobe added a number of standard effects to Flex to make your applications look even better with smooth transitions using those effects. To give you an idea, lets create a ViewStack that switches views using effects.
Image as Button in a DataGrid
February 14, 2009
Just as the MouseWheel controlled slider idea, I had this idea when I was working on my flex MP3 player as well. I wanted to give the user the possibility to add tracks to a playlist by clicking a small plus icon in a DataGrid. There are a couple of things that have to be done to achieve this:
- Use an itemRenderer to show an Image instead of text
- Put the image in button mode so that it can be clicked
- Put an event handler on the click or double-click event of the image
- Code the event handler
Control HSlider or VSlider with the Mouse Wheel
February 14, 2009
When I was working on my Flex MP3 player I thought it would be nice to make it possible to control the volume slider with the mouse wheel. I started scrolling trough the events of the HSlider component and luckily, there is a standard event that is dispatched when a user uses the mouse wheel.
Simple Flex & PHP Example
February 14, 2009
How do i get my data from Flex to PHP? I wondered about this a year or so ago when I was just getting to know Flex. I have to admit that my PHP skills are not that good, I can get things in and out of MySQL databases and that’s about it. But enough about me, let’s make a simple Flex application that calls some PHP script on the server.
Using the Repeater in Flex
February 14, 2009
So you might come across some situation in which you want to repeat some part of your layout for each data item, but the number of items is unknown.
Fortunately for us, Adobe provided a component with Flex which we can use to achieve just what we want: repeating parts of the layout for every item in the data collection.
ViewStack, LinkBar and ButtonBar Example

When you are developing your Flex or AIR applications you’ll probably have one or more views where you want to put your components. Adobe Flex offers you multiple components to work with multiple views. Two examples are the TabNavigator and the ViewStack.
Using A ComboBox in Flex
February 13, 2009
The ComboBox or DropDown in other development environments, is a very useful input element. The great advantage of it is the fact that you can determine the values that a user can choose.
The items that are choosable in a combo box can be both static as dynamic. The following examples show you how to use both approaches.
Using the ProgressBar with a file download in Flex
February 13, 2009
So sometimes you’ll have time consuming procedures in your Flex application. Flex provides a nice moving clock thingy to let the user know that it’s doing something, but it doesn’t give the user any information about the progress.
Fortunately, Adobe provided the ProgressBar with Flex. To see how you can use the progressbar in combination with a file download from the server, see the following example.
Images in DataGrid depending on data
February 13, 2009
Flex DataGrids are usually used to give the user some overview of data. Sometimes we want to use a certain value in the data to describe something else (derive a value from the data).
For example, we want to display if a product is in stock yes or no using the following data:
