A practical guide to connecting hardware to Flex

This session will look at the revolution in low cost easy to program embedded computing. We will focus on the arduino open source hardware and software platform and zigbee network modules and how both of these can be easily connected up to Flex.

You can find out more here.

After the talk I will be posting my slides and the code on this blog.

My current projects are coming to a close and I'm available from the last week of February onwards for 4 days a week. Anyone out there that could use my skills?

I have 10+ years CF experience, 5+ years Flash experience and 2+ years of Flex experience (inc commercial Flex 3 apps).

I'm a Adobe premium partner, an Adobe certified instructor and an Adobe certified developer in Flex, Flash and ColdFusion.

I find that the default sliders have a few minor usability issues a) the thumb is too small and b) the hit area of the the thumb is too small. Perhaps I just need new glasses or a bigger screen?

You could skin a slider and change the thumb graphic but it's just as easy to fix with a little actionscript.

When a user types a character the default behaviour of a list box is to jump to the first item that starts with that character. This is fine for small lists but for a long list of items it's not very useful. A better solution would be if the list box remembered what the user typed and keep looking for matches on the second character, the third character, etc etc.

Run into a nasty little bug with Flex datagrids the other, under some situations Datagrid columns with their visibility set to false will be displayed!

Here's a workaround.

If you have a list box with a large number of items in it it can be hard for someone to find the item in the list that they need. One way around this is you add a filter on the list box.

Here's how it's done.

With flex datagrids you sometimes find you have a datagrid with multiple columns but only one or two columns are editable.

Which column are editable are not immediately apparent to a user, they have to click on cells to find out what's editable or not editable.

You can add some sort of visual indication to show what cells are editable (see here) OR you can make clicking on a row edit a cell.
