Intuit’s flexy PaaS
Intuit, better known for its accounting software, is one of the latest entrants in the PaaS, ecosystem. It recently launched its Quickbase developer program, currently running in closed beta. What’s particularly interesting about it, is that it is based in Adobe Flex, as we shall see.
Of course, looking to assess the various PaaS offerings out […]
Using Force.com as a Flex back end…
or depending how you see it, using flex as a force.com application front end.
Either way salesforce is one of the PaaS (platform as a service) providers, that sees in Flex the technology for adding rich user interfaces to its applications. As we’ll have the chance to point out in numerous occasions, RIA’s and SaaS (software […]
What can be behind Flex?
Focusing enough on Flex capabilities we shouldn’t overlook the fact that Flex is a Rich Internet Application development tool, and as such will almost always have to exist ontop of an IT infrastructure, providing data persistence, logic, workflow and messaging. Actually there is a lot in that backend stack, that makes a whole difference in […]
Keeping rotated content clipped
Every container in Flex by default clips its content, when that exceeds the boundaries of the container. Clipping appears to be a computational behaviour that kicks in once a display object exceeds the container boundaries either due to its position coordinates (x,y) or its size (width, height) . Missing something? Well yes; a display object might also […]
A suggested Cairngorm based modular architecture
There have been a few discussions around after Flex 2.01 introduced the concept of modules, about issues with using modular architecture along with Cairngorm framework. I will not address here problems arising from using singletons along a shell and loaded modules (as done here), but rather present a way to integrate a Cairngorm based shell […]
DataGrid with flexible row height
In one project I needed to have a data grid cell present some hierarchical data and I thought I could just use a tree control as the item data renderer for that grid column.
This what I got:
As you can see if you open the trees, the data row is not adjusting […]
Time-delaying Cairngorm Commands Execution
In cases where data are edited in a Flex client and subsequently have to be saved on a server, one has to manage the frequency of those server calls.
One way of doing this, is adding an extra step, for the user to save the changes made. So image you have an editable data grid, presenting […]
Enhanced search string ComboBox
The standard behaviour of the Flex framework combobox, is to adjust its selected option as the user types in characters. However values are looked up only by the first character, i.e. user types in ‘a’ and the first option starting with ‘a’ is selected. He then types ‘b’ and the first option starting with ‘b’ is selected.
Now this […]
The illusive itemRenderer
The item renderer is a powerful concept in Flex, that enables custom implementations of data presentation and input within controls like Lists, DataGrids and Charts. In our last post, we saw how a custom item renderer can be used within a bubble chart to enable interactivity. We showcased that using a chart with one […]
