Color name to uint value

Posted on by — No Comments ↓

Filing under the “why didn’t I find this before” folder. On the Adobe Flex forums, there was a question about changing the color value of a button based on a switch statement. The user was trying to change the value to “Red”, “Yellow” or “Green”. In the button, the type for color is uint value, so the input needs to be something like “0x990000” for “Red”. I usually just insert in the uint value for a color and not the name, since I usually have to change it. But, this question on the forum got me thinking and searching for Continue reading Color name to uint value→

DataGrid Row Move

Posted on by — No Comments ↓

Another question on the Flex Forum about how to move a selected row on the DataGrid up or down, based on a button click.  The answer is straight forward, but with a catch. When you click on the DataGrid, it will give you an index for the row you have clicked.  The first row in the DataGrid is 0.  If you wanted to simply move a row up and down the DataGrid, then you simply add or subtract 1 from the selected index. Simple enough.  Unless you sort the DataGrid, which throws that out of wack and is pointless.  So, Continue reading DataGrid Row Move→

Column Chart with Item Renderer – updated

Posted on by — No Comments ↓

Okay, it didn’t take me long to get back and do some more fiddling with the Column Chart Item Renderer. I went ahead and changed the static ArrayCollection to a dynamic one, because I was trying to figure out something with Themes and needed a button and the button should do something. The ArrayCollection is fairly simple for this chart, so all I did was create a couple of random values from 0 to 100 and made the “date” value the counter time 10. I set it up so that you can press a button and create new data, which Continue reading Column Chart with Item Renderer – updated→

Column Chart with Item Renderer

Posted on by — 2 Comments ↓

When doing the Column Chart with fillFunction for a question in the Flex Forum, the poster said that he was trying to do something a little different. Instead of a simple fill, he wanted the fill to be semi-transparent with a solid border. When I looked at the iFill function, it didn’t have a stroke option and it doesn’t seem that the standard column item deals with the column border. My guess was, that an item renderer should be used for the column instead. Within the item render, you can create a rectangle graphic and then adjust the border and Continue reading Column Chart with Item Renderer→

Column Chart with Fill Function

Posted on by — No Comments ↓

When you have a column chart, sometimes you want to change the column colors based on the data. A question in the Flex Forum asked how to alter the column color on each column. To do this, yo need to use the fillFunction on a ColumnSeries to set the color of the fill. One issue with doing this, is how it affects the chart legend. If you use the fills property or the fillFunction to define the fills of chart items, and you want a legend, you must manually create the Legend object for that chart. But, this just gives Continue reading Column Chart with Fill Function→

TextArea auto scroll update

Posted on by — No Comments ↓

There was a question on the Flex Forum about how to auto-scroll a TextArea. You can set the VerticalScrollPolicy to auto or you can add a little code to valueCommit to move the vertical scroller. Since I lost where I created the example of adding the code to the valueCommit, I decide to remake the example to show the difference. Both text areas are updated every 10 seconds with a random generated sentence, based off of quotes from Mark Twain. The left TextArea box uses the VerticalScrollPolicy set to “auto” The right TextArea box uses the valueCommit code to move Continue reading TextArea auto scroll update→
