Re: [flexcoders] Re: how to give focus to a new browser window
Maybe minimize the application if it's still the front most application, possibly after showing an alert to say what you're up to? Or maybe just throw up a dialog to say you've opened up a browser window, again maybe only if you're still front most? Just some ideas.

Re: [flexcoders] How do I make sure container's child components have applied new style before ImageSnapshot?
Thanks Alex for your response.
I tried all kinds of combinations of capturing the updateComplete
event on different components as well as chaining callLaters with
checking of properties etc, but couldn't get it to work without side
effects.
Eventually I found that all I needed to do was validate the container
and the Legend control before taking the snapshot, the important part
being that the container must be validated before the Legend so that
the Legend picks up the CSS changes when it's validateNow is called.
Here's my new method of saving pictures of charts etc for anyone that
might come across the same problem, it's not particularly efficient
what with all the validateNows (3 in total), but seeing as this is
triggered from a button press or hot key, the user isn't doing
anything else and must have the result as quickly as possible, it's
not such a big deal. It's pretty responsive.
private function saveToFile():void
{
var crossPlatform:ICrossPlatform;
crossPlatform = CrossPlatform.getInstance();
if (mainTabs.selectedChild.id == casesTab)
{
var dataString:String = delimitedCaseListString();
crossPlatform.saveStringToFile(dataString, currentFilter.sFilterName
+ .txt);
}
if (mainTabs.selectedChild.id == pieChartTab)
{
pieChartContainer.styleName = forPrint;
pieChartContainer.validateNow(); //*** Make sure container has style
set and displayed.
pieChartLegend.validateNow(); //*** Make sure troublesome child has
style set and displayed.
callLater(saveSnapshotAndResetStyleName, [pieChartContainer]);
pieChartContainer.validateNow(); //*** Kick off snapshot in timely
fashion.
}
}
private function
saveSnapshotAndResetStyleName(component:UIComponent):void
{
// Take snapshot and remove print style.
var dataBytes:ByteArray = byteArrayFromComponent(component);
pieChartContainer.styleName = null;
// Save image to file.
var crossPlatform:ICrossPlatform;
crossPlatform = CrossPlatform.getInstance();
crossPlatform.saveByteArrayToFile(dataBytes,
currentFilter.sFilterName + .png);
}
private function byteArrayFromComponent(component:UIComponent):ByteArray
{
var imageSnapshot:ImageSnapshot =
ImageSnapshot.captureImage(component);
return imageSnapshot.data;
}
It seems to work.
Thanks for trying to help, trying to implement something off your
suggestion lead to the final fix.

components have applied new style before ImageSnapshot?
Hi,
I'm having a bit of a problem with capturing a snapshot of a VBox's
contents with a simple colour change applied through a styleName
change.
The container layout is something like:
mx:VBox id=pieChartContainer width=100% height=100%
horizontalAlign=center
mx:Label id=pieChartTitle
text={currentFilter.sFilterName}
fontSize=14
fontWeight=bold
textDecoration=underline/
mx:PieChart id=pieChart width=100% height=100%
showDataTips=true dataTipFunction=pieChartDataTipFunction
resizeEffect={moveAndResize}
mx:series
// Some series, not relevant to problem.
/mx:series
/mx:PieChart
mx:Legend id=pieChartLegend
dataProvider={pieChart}
width=100%
visible={chkPieChartLegend.selected}
includeInLayout={chkPieChartLegend.selected}
direction=horizontal
resizeEffect={moveAndResize}/
/mx:VBox
Because by default my app has a dark theme with light text applied
through CSS, before capturing a snapshot, I set the style to:
.forPrint
{
color: #00;
}
This means the image should have black text which is good for print
etc.
I call saveToFile() to start the capture, only when the referenced pie
chart is visible.
private function saveToFile():void
{
pieChartContainer.styleName = forPrint;
callLater(saveSnapshotAndResetStyleName, [pieChartContainer]);
pieChartContainer.validateNow();

colour before the snapshot is taken, if the Legend control is included
in the container it still retains it's light label colour.
As you can see from the code above I've tried to delay the capture
until the refresh happens by using a combination of callLater and
validateNow, but that doesn't seem to help.
If I comment out the resetting of the container's styleName after the
snapshot has been taken, the Legend control is shown with the required
black text, so the change does happen, but not before I take the
snapshot.
Has anyone got any advice on how to make sure a container and it's
child controls have applied a new style before using ImageSnapshot?

[flexcoders] Capturing Cmd-C (or Ctrl-C) keyboard event from modular Flex application in browser or AIR.
Hi,
It seems that it is impossible to capture the keyboard event normally
used for copy when running a Flex application in the browser or as an
AIR app, presumably because the browser or OS is intercepting it first.
Is there a way to tell the browser or OS to let the event through?
For example, on an AdvancedDataGrid I have set the keyUp event to
handleCaseListKeyUp(event), which calls the following function:
private function handleCaseListKeyUp(event:KeyboardEvent):void
{
var char:String = String.fromCharCode(event.charCode).toUpperCase();
if (event.ctrlKey char == C)
{
trace(Ctrl-C);
copyCasesToClipboard();
return;
}
if (!event.ctrlKey char == C)
{
trace(C);
copyCasesToClipboard();
return;
}
// Didn't match event to capture, just drop out.
trace(charCode: + event.charCode);
trace(char: + char);
trace(keyCode: + event.keyCode);
trace(ctrlKey: + event.ctrlKey);
trace(altKey: + event.altKey);
trace(shiftKey: + event.shiftKey);
}
When run, I can never get the release of the C key while also
pressing the command key (which shows up as KeyboardEvent.ctrlKey). I
get the following trace results:
charCode: 0
char:
keyCode: 17
ctrlKey: false
altKey: false
shiftKey: false
As you can see, the only event I can capture is the release of the
command key, the release of the C key while holding the command key
isn't even sent.
Has anyone successfully implemented standard copy and paste keyboard
handling?
Am I destined to just use the C key on it's own (as shown in the
code example) or make a copy button available?
Or do I need to create the listener manually at a higher level and
pass the event down into my modular application's guts?
Thanks in advance for any help.

Re: [flexcoders] No Serial Numbers for Flex Builder 3?

Then ran the installer that I copied to my hard disk, and OK'd the This application was downloaded from the internet... dialog that now properly displayed (I think this dialog might have been to blame for the first no-show).

Fixed it.
I got close to solving the problem by removing the compareFunction from the
Sort I was
constructing at startup, but that meant numeric, date and compound columns were
always
sorted alphabetically instead of numerically, by date or through the two or
more data
fields that made up the column respectively. But at least it was sorting in the
right
direction and the direction could be changed correctly. This was definitely my
fault, I
shouldn't have used the custom compareFunction because I dynamically add a
sortCompareFunction to any AdvancedDataGridColumn that needs it when adding the
user's preferred columns to the AdvancedDataGrid, so I didn't need to reference
another
custom compare function on the data provider.
But why wasn't the AdvancedDataGrid using it's column's sortCompareFunction
definitions?
When I created the SortFields for the initial sort I was setting the ignore
case property to
true just as a means of getting to the descending parameter that I was truly
interested in,
when I set that to false, suddenly the AdvancedDataGrid was using the correct
sortCompareFunctions for it's columns. Very strange.
On reflection, it could be that the framework is assuming that if the SortField
has it's
ignore case property set to true then it must need to do an alphabetic sort,
regardless of
whether there's a custom compare function on the column or not.
Hey ho, it's fixed now.
Cheers,

* it's always in ascending order, even though the column headers show
the sort arrow correctly pointing down if the saved sort was descending.
* if you click on the column header to re-sort it nothing happens,
the sort arrow will flip-flop between pointing up and down as many
times as you like, but sort order is always ascending.
* The sorted column will not sort properly until I sort another
column by clicking it's header first, then it'll properly sort
ascending and descending when clicked.
The Sort object I'm assigning to the casesArray ArrayCollection above
looks OK, it just seems there is something not quite right in the
way the ADG uses it.
If anyone has any advice, I'd be very grateful.
Thanks,

Hi Kanu, You're correct, you need to create a handler for the result event of the first webservice, and in there call the second service.

Re: [flexcoders] Retrieving saved DataGrid columns array from local SharedObject.
Just to follow up...
I installed hot fix 2 yesterday, which cleared up my problem with
setting the width of non-visible columns (i.e. scrolled off to right
in this case).
So, thank you jake247, your code is working very well for me.

jake247, your code works pretty well, I think I could probably alter
it to get what I really want if I work on it a little more (the
columns may need to be added or removed).
However, I assume you're using a grid without a horizontal scroll
bar, as I seem to have found a bug in the DataGrid when running your
code. When it get's to the point where the width is set on the newCol
for a column that is off to the right and not visible until the
scrollbar is used, it complains about a missing property because it's
internally trying to reference an element in the visibleColumns array
which isn't there. I need to either fix this in the DataGrid source
or find a work around.

Is there a kind soul that can point me in the right direction?

Re: [flexcoders] Re: Datagrid auto sorting. Has anyone done this?
As a total newbie, having just seen this in the docs, I may be totally wrong, but have you looked at the DataGrid's placeSortArrow() method? I'm not sure how you use it, but it looks promising.

Basically you just set the sort on the collection, and the DataGrid will appropriately display a sort arrow on the header. So it's the collection you need to sort.
