We are proud to announce that Webapper is sponsoring RIA Unleashed in Boston this year. Brian Rinaldi has been putting together some great Flex camps in years past, and we jumped at the chance to sponsor this expanded event. This year, it’s an all-day conference with three tracks: Flex/Air, ColdFusion, and Related Technologies. Steven Erat and [...]
We’re happy to announce another big notch in our Web application engineering belt–Steven Erat joined Webapper last month! Steven has spent the past decade of his life as a senior member of the ColdFusion engineering and support divisions at Allaire/Macromedia/Adobe. Most recently at Adobe he was an engineer on the Flex SDK team. Unless you’ve [...]
The other day, someone asked me how they could re-use the code sample from Igor Costa’s post about getting the Rich Text Editor to output XHTML. Whenever you want to add functionality to an existing control, you just need to extend it. Here’s how:
Here’s the top bit of code from my XHtmlEditor.as file:
The actual code [...]
Someone in #flex was talking about how there were no good examples for doing uploads with Flex and ColdFusion. Sounded like an excellent topic to cover here. Now this example is a tiny bit more complex than previous examples, because I needed to cover two methods of functionality: single file uploads and multi-file uploads. Both [...]
There was some confusion in #flex yesterday. The question came up on how a child component could access the parent component. Eventually, it came down to they wanted to pass some data from the child back to the parent.
Well, the “black box” method of component programming says that we should use custom events to send [...]
Someone on #flex asked about preventing text from appearing in a TextInput or TextArea, when the user is using a keyboard shortcut. After a little discussion, I came up with a working example. I decided to use shift-space to simplify things.
The first assumption is that you’re listening for keyboard shortcuts at the application level:
Now, you’ve [...]
Over the weekend I was writing a simple little app, and came across something that should have been trivial, but turned out to throw me for a loop momentarily. I needed to drive some data from XML instead of my tried-and-true ColdFusion components, and I realized I’d never done it before. So, here’s the example:
If you’ve ever created a form tall enough to require a vertical scroll bar in Flex, you may have not even have noticed that you have you scroll down manually when focus moves below the visible part of a window. Users, however, notice, especially if they don’t have a scroll wheel on their mouse.
I’ve decided since I attempt to help people in #flex (on EFNet) and #coldfusion / #cfflex (on DALNet) on a daily basis, that I’ll pick one simple question and try to whip up an example for everyone to see.
Today, someone asked how to scale all children of a container. The basic answer is to just [...]
I forgot to mention here that I wrote up a nice Actionscript library for manipulating lists. It includes a majority of ColdFusion’s list functions, plus a few that we commonly use here at Webapper. Sometimes you just need a list instead of an array.
Get the library here.
