[flexcoders] New to FlexBuilder Development Tool
Finally, I got my own FlexBuilder standard edition. I am quite new to this tool. I have mostly developed apps by simply using the command line compiler. I am browsing for some examples to load to my FB3 and I found this example: http://demo.quietlyscheming.com/ChartSampler/app.html As you can see from this site, the source can be downloaded (zip file). I have already downloaded the zip file and was trying to load it through FB3 via menu item - File | Import | Flex Project but it gives me the message that it is not a valid Flex Project. Next that I did was to simply unzip the file and copy the source codes (including the directory structure of those in the zip) and placed them into the source folder (SRC) of the New Flex Project which I created. When I try to run the application, it gives me a message saying Errors exist in required project(s): ChartSampler Proceed with Launch? How would I be able to load properly all the components which I have downloaded from the demo site and run it successfully? Am I missing something? Thanks.

Re: [flexcoders] Re: DateChooser Calendar pop up
There are too things that crop to mind. First, if you just want the user to select the number of days, isn't that an integer in a TextInput? I'm assuming that is the wrong path, so... You might be describing allowMultipleSelection which can allow the user to select multiple days in the DateChooser.

[flexcoders] Resizing transparent png
Hi All, I am trying to apply a roll over/out resize or zoom effect on a Button with graphical skins. When the mouse is over the image I want it to grow and shrink on exit(currently using roll over/out events). My png skins are transparent and have round shapes, when I resize/zoom up or down the image quality is poor and shows pixelization on the round edges. I have tried swapping the images (large vs small) when the effects end but it feels clunky. I have tried using a straight image vs a button component but get the same result. I also tried just specifying the large image as the over, down skins and applying a resize effect to the button but it also is clunky. Cache as bitmap, smoothing, maintain aspect ratio, scale content seem to have no effect on my resizing of these transparent pngs. Not sure what I am doing wrong, any help is much appreciated.

[flexcoders] different context menus for rows, columns and cells of a datagrid
I have a custom datagrid and I want to have it such that the context menu has different menu items based on what part of the grid is clicked. If a column header is clicked, show Insert column... The first column of the grid is a read-only, row id column. If one of the row headers is clicked, show Insert row If one of the cells in the grid is clicked show another menu. I see the DataGrid has a contextMenu property but this would apply to any area clicked. Not sure if I should (or how to) dynamically change the menu based on what area is clicked. For the column header, I see there is a DataGridHeader class that has a contextMenu property. I can get to the columns of the datagrid but not clear on how to get to the DataGridHeader for the columns. Any ideas how to approach this? Thanks, Phil

[flexcoders] Re: New to FlexBuilder Development Tool
Angelo You picked a pretty big project to start with. Here is what I did to get it running (Dirty Hack): 1. Extracted the zip file on my computer (And deleted the .svn directory) 2. Created a new project in Flex Builder named ChartSampler. 3. In Windows Explorer, deleted the ChartSampler.mxml file then copied the unzipped files into the src directory. 4. In the examples/styling/MXMLStyles.mxml file, commented out the s:Selector stuff (There is no Selector class there) 5. Copied the arial.ttf font from my fonts directory into the src directory. 6. Run the app.mxml file or the ChartSeriesStyles.mxml files. They should both work. This kind of thing happens quite a lot with downloaded examples.

Hello again, I am testing the Trader desktop sample with blazeds backend. when I use the polling amf, I am able to see the stock updates. while the flex frontend is running, if I restart the backend after 5 minutes, then the frontend no longer gets the updates. If I refresh the web page, then it works again. If I restart teh backend server quickly (lets say 10 seconds), then it works. It looks like if the flex client cannot connect to backend server, it tries to reconnect few times, once it cannot connect after many tries it gives up. where can I change the settings about how often to retry?

RE: [flexcoders] Re: variableRowHeight
The list always remeasures the renderers. It assigns the .data property, sets explicitWidth then calls measure(), then checks for explicitHeight then measuredHeight, and that's the height it uses. But if you can only see three renderers, it will probably create a new one for the one just off-screen, but it will re-use the first renderer for the fifth row assuming the first row is now off-screen. If that renderer still thinks it is in the expanded state when it is not representing row 5 which is not expanded, then scrolling will be off.
