Spark DataGrid with Safari
Hello,
I tried today spark datagrid and used the examples from Adobe Help. But when testing with Safari I have problems with the cursor.
For instance when I resize the column width, I can't see the cursor anymore, I have to click first outside datagrid to make the cursor
visible again. But I can move the cursor, can click even see the cell color changing but without exactly knowing where the cursor is.
Is this a known issue?
With Firefox there is no problem.
Thanks for your help.
Kind regards,
ND
The most recent Safari browser does not work well with the debugger player. I’ve had to switch to another browser.

Spark DataGrid with Dynamic Column Width
Lets suppose I have a Spark Datagrid with no explicit typicalItem. When the Datagrid is initialized, the column widths are calcualted correctly based on the contents of the dataprovider. However if I add/remove an item from the dataprovider, or modify the one of the objects in the dataprovider, the column widths never update to reflect the change. Is the the correct behavior for a DataGrid? If so, is there any method I can call to force the DataGrid to recalculate and redraw the column widths?
When Spark DataGrid doesn't have a typicalItem, it uses the first dataProvider item as the typicalItem. If you change that, the DataGrid won't pick it up immediately. You can invalidate the current typicalItem using dataGrid.invalidateTypicalItem().

Flex Spark Datagrid - Scalable (font size) with No scroll Bars
I was wondering what would be the most optimized way to scale (increase/decrease) the fonts size in a Spark DataGrid with NO Scroller, so as to make it when the User Resizes the DataGrid, the Fonts inside the Grid would increase/decrease.
Is there a way to listen for the size change of the DataGrid?
I would probably need to change the font size to increase/decrease as the event gets fired on Datagrid Resize.
Any suggestions?I've pasted as much code as I can legally can. What i would like to achieve is that when the the window resizes, the Content & the DataGrid Scales. I am also aware of scalemode on the VBox, though it scale oddly with width more than height (this is internal).
Else, I tried:
protected function vgroup1_addedToStageHandler(event:Event):void
//stage.scaleMode = StageScaleMode.EXACT_FIT;
stage.scaleMode = StageScaleMode.SHOW_ALL;
stage.align = StageAlign.TOP_LEFT;
scaleX = .5;
scaleY = .5;
/* if(stage.stageWidth != (event.currentTarget as VGroup).width || stage.stageHeight != (event.currentTarget as VGroup).height)
var scaling:Number = 1;
if(width>height)
scaling = stage.stageWidth / (event.currentTarget as VGroup).width;
else
scaling = stage.stageHeight / (event.currentTarget as VGroup).height;
scaleX = scaleY = scaling;

Flex Spark DataGrid BUG skipping rows on refresh
I have a small one file example that demonstrates this Flex DataGrid bug.
I tried to report it to Flex bugs and the page timed out.
I am filling a column in a spark datagrid with checkboxes to select that row.
In the header of that column is a checkbox to select ALL the rows.
However, the middle row is not getting refreshed so the display is wrong.
The checkbox looks empty when the backing value is correct.
I have added a print to the code that sets the values in the data and it is setting everyone.
But when I print the isSelected code it is NOT being called on ONE (the middle) visible row.
If I move away or scroll up and down the check box shows the check mark.
So My only conclusion is that refresh has a bug.
Here is the example that demonstrates the problem.
Simply select the header checkbox and the 3rd checkbox does not get updated on refresh.

Selection issue with editable Spark DataGrid
Hi everyone,
I am evaluating the new Spark DataGrid and I'm having a very strange issue with the behavior of selection in an editable instance.
Here is my test application: http://www.playcalliope.com/flex/DataGridSelectionIssue.html (code here: https://gist.github.com/1129160)
And here are the steps to reproduce the issue:
select the very first cell at the top-left corner of the grid (the one with "Gabriele");
click on it once more, the editor appears;
now click on the cell just to the right of it (the one with "Genta").
You should see that editing ends as it supposed to do, but selection is placed on the third cell (the one with a 5 in it) instead on the one you clicked on. Playing a little with the grid you should see that this isn't the only case, but selection is really behaving randomly.
I am using SDK 4.5.1.21328.
I think this is a very basic usage case.. I can't believe this is not working properly, what am I missing?
Thanks a lot,
Gabriele Genta
Message was edited to add live exampleYour running into a known bug, https://bugs.adobe.com/jira/browse/SDK-30088.
The bug will be fixed in the Mega release. To work around the bug you can create a custom editor and remove the "dataGrid.validateNow();" call in DataGridEditor.save().
Here's how I modified your example to workaround the bug:

Playing with the spark datagrid
I'm Playing with the spark datagrid and have a column set up like so:
<GridColumn width="140" headerText="Margin" headerText.editMode="Margin (editing)" dataField="margin" editable="false" editable.editMode="true" itemRenderer="gridColumnRenderer" >
</GridColumn>
I would like the item render to change colour based on the state of the outerDocuent, is this possible?
I tried this but can't get to the outerdocument
<?xml version="1.0" encoding="utf-8"?>
<s:ItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
autoDrawBackground="true">
<s:Label text="{data.margin}" backgroundColor="{ outerDocument.currentState =='editMode'?0xffffff:0xdddddd}"/>
</s:ItemRenderer>I believe you will need to use GridItemRenderer instead of ItemRenderer as your base class for renderers in the spark DataGrid. Does it work if you change to that?

How to resize the spark datagrid collumns based on the headertext?
Hi friends,
I am using spark datagrid for displaying the tablur data in my application, when i setting the dataprovider property of the datagrid, it displays the content exactally what i expeceted.
but the widht of the collumns are based on the content of the dataprovider, i am not able to see the full collumn name in the datagrid's header. I want to display the full collumn name to the users without setting the collumn width explicitly because the data are dynamically returned from the server. could you pls give me some ideas to acheive this...?
Thanks in advance.Hi Karthikeyan Subramain,
You can make use of typicalItem proberty to set the column width.
Here is the link for sample code which uses typicalItem:

Spark DataGrid Embedded Font Quandary
01. In everything that follows, I am talking about the latest [21328] version of the SDK, not that I believe that my problems have anything to do with that release, just so anyone interested and willing to help will know the version.
02. My application happens to be rooted in AIR's WindowedApplication, but again, I do not think that has any impact on my problems; I believe the same results would obtain for a Flex Application.
03. I have a custom renderer for the Spark DataGrid which extends DefaultGridItemRenderer. It works fine. Its primary job is to change the font characteristics of each row in the list as a visual clue to the user as to the specific nature of the content that is accessible. Some entries are just in the Regular font, some in Bold, some in Italic, and some in Bold-Italic.
04. I have, for most of the project, embedded the necessary fonts like this:
[Embed (source="C:/Windows/Fonts/ArnoPro-Caption.otf", fontName="ArnoPro_BI_4",
fontStyle="italic",
fontWeight="bold",
mimeType="application/x-font",
embedAsCFF="true",
unicodeRange="U+0021-U+00ff, U+20ac-U+20ac")]
private const ArnoPro_BI_4:Class;
As I said, that all works just as advertized. But, that method of embedding carries the somewhat painful burden of slower compilations, so for the last 24 hours I have unseccessfully been trying to replace that with:
[Embed (source = "../resources/assets/ArnoPro_BI_4.swf", symbol="ArnoPro_BI_4")]
private const ArnoPro_BI_4:Class;
where the swf file was produced via fontswf, using this incantation:
fontswf -4 -u U+0021-U+00ff,U+20ac-U+20ac -b -i -a ArnoPro_BI_4 -o ArnoPro_BI_4.swf C:/Windows/Fonts/ArnoPro-Caption.otf
06. By all that is holy, the two different means of embedding the font ought to yield the same result, but they do not. I have debugging code inserted to print out the list of fonts upon initiation of the application, and they are identical. Both means of embedding do succeed in getting the embedded fonts into the .swf, but the attempt to use the fonts fails using the second approach.
There is, of course, no change being made to the code in the item renderer which merely uses setStyle() to effect the row-by-row result. The result in the second case is that the only style of the embedded font that renders is 'regular'.
07. I have used the 'keep-generated' facility to look at the code being generated by the mxmlc compiler and can see that different code is emitted, but it does not help me find a fix to the problem. Both forms of the meta-tag do something; both methods of embedding seem to correctly register themselves with the FontManager, but only the method of embedding which actually performs the transcoding during compilation seems to result in a set of registered fronts which can be found and correctly used to render output based on the runtime setting of the font style.Thank for the reply
I hoped that my posting indicated how the fonts in the the .swf file were constructed. The "-4", argument to the command-line tool, fontswf, as far as I can tell, is the precise analog to the "embedAsCFF" argument in the [Embed] syntax. That is what makes it so perplexing. Given all the external documentation that is available for each tool/methodology, I would have thought that the resultant bytecodes, classes, flags, whatever, would have been identical. The only difference would be the timing of when the transcoding took place.
Since it is clearly more efficient to only transcode whatever set of fonts an application needs once, not once per build/test turn-around, I would really like to make the fontswf workflow work. For those of us outside the beneficial environment of your licensed tools, the kindly-provided alternative to the facilities built into Flash Professional and/or Flash Builder give us the greatest degree of productivity.
Whoever has access to the source code for Font [I can only see the uninteresting FontAsset in the SDK] can probably determine what difference might result from mxmlc working with this intermediate output, when inline transcoding is 'tagged':
package
import mx.core.FontAsset;
[ExcludeClass]
[Embed(fontName="ArnoPro_IT_4", _resolvedSource="C:/WINDOWS/Fonts/ArnoPro-ItalicCaption.otf", fontStyle="italic", _line="1189", _pathsep="true", embedAsCFF="true", fontWeight="normal", unicodeRange="U+0021-U+00ff, U+20ac-U+20ac", source="C:/Windows/Fonts/ArnoPro-ItalicCaption.otf", _column="2", exportSymbol="AIRZoom_ArnoPro_IT_4", _file="G:/FP/AIRZoom/src/AIRZoom_AS.as", mimeType="application/x-font")]
public class AIRZoom_ArnoPro_IT_4 extends mx.core.FontAsset
public function AIRZoom_ArnoPro_IT_4()
super();
versus this, when swf extraction is 'tagged':
package
import mx.core.FontAsset;
[ExcludeClass]
[Embed(fontName="ArnoPro_IT_4", _resolvedSource="C:/WINDOWS/Fonts/ArnoPro-ItalicCaption.otf", fontStyle="italic", _line="1191", _pathsep="true", embedAsCFF="true", fontWeight="normal", unicodeRange="U+0021-U+00ff, U+20ac-U+20ac", source="C:/Windows/Fonts/ArnoPro-ItalicCaption.otf", _column="2", exportSymbol="AIRZoom_ArnoPro_IT_4", _file="G:/FP/AIRZoom/src/AIRZoom_AS.as", mimeType="application/x-font")]
public class AIRZoom_ArnoPro_IT_4 extends mx.core.FontAsset
public function AIRZoom_ArnoPro_IT_4()
super();
The only difference is that value for '_line' which probably only indicates that one of the two processes has a comment or empty line somewhere. -
How to change header font style in Spark DataGrid?
I'm looking since last week for a way how to change the font style of the header in a Spark DataGrid. It drive me nuts that I can't find a way to do this. Have anyone one an idea how to achieve it? Any help is appreciated.
Thanks,
- ArturHi,
Some styles won't work because some text styles got hardcoded into the DefaultGridHeaderRenderer's Label. You'll run into this issue not just with the DataGrid headers but also things like the Panel's title and other places where we have text. One way to get around this issue is to create your own custom headerRenderer based on the default one and then redefine the headerRenderer skin part in the skin.
First, create a subclass of the DefaultGridHeaderRenderer and tweak the "labelDisplay" to your liking (or even just take out all the styles and style it on your own as you had earlier using your custom header renderer's name). Example below (I named it "CustomHeaderRenderer"):
<?xml version="1.0" encoding="utf-8"?>
<skins:DefaultGridHeaderRenderer xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
xmlns:skins="spark.skins.spark.*"
xmlns:comps="comps.*">
<fx:Declarations>
<!-- Remove fontweight="bold" and other styles as you wish
Must be a component and not a factory. -->
<s:Label id="labelDisplay"
verticalCenter="1" left="0" right="0" top="0" bottom="0"
textAlign="start"
verticalAlign="middle"
maxDisplayedLines="1"
showTruncationTip="true" />
</fx:Declarations>
</skins:DefaultGridHeaderRenderer>
Next, create a simple DataGrid skin by creating a subclass of the spark.skins.spark.DataGridSkin in MXML and defining a new headerRenderer component in the fx:Declarations section. Example below (I named it "CustomDataGridSkin"):
<?xml version="1.0" encoding="utf-8"?>
<skins:DataGridSkin xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
xmlns:skins="spark.skins.spark.*"
xmlns:comps="comps.*">
<fx:Declarations>
<!-- Must be a factory with the right id for the skin part -->
<fx:Component id="headerRenderer">
<comps:CustomHeaderRenderer />
</fx:Component>
</fx:Declarations>
</skins:DataGridSkin>
Last, assign your new skin as the skinClass of your DataGrid (either in MXML or as a style):
<s:DataGrid skinClass="comps.CustomDataGridSkin">
I know it's not pretty, but it's the result of trading off between having completely custom skinning vs. having knobs to tweak every style. Hope this helps.

Column stretch event in spark datagrid
Hi everybody,
These days I'm converting our Flex application from Flex 3 SDK to Flex 4.5 SDK (Hero).
I've a problem with the spark datagrid, and more specifically, the events listening on the columns.
How can we know that the columns in the spark datagrid are stretched or shrinked?
In Flex 3, there was a DataGridEvent.COLUMN_STRETCH event on the datagrid and I can't find the equivalent in Flex 4.5.
If you have any tips.... thanks!!!!When a GridColumn is interactively resized "widthChanged" events are dispatched because the column's width property is set. To track the entire column separator press-drag-release gesture you can listen for GridEvent.SEPARATOR_MOUSE_DOWN,SEPARATOR_MOUSE_DRAG, etc..events on the DataGrid's columnHeaderGroup skin part. If you wanted to change the way the interactive column resizing works you'd have to subclass DataGrid and override protected methods like separator_mouseDownHandler(event:GridEvent), separator_mouseDragHandler(event:GridEvent).

Can I create a custom scrollbar for my spark datagrid
Basically I'm trying to customize the look of my spark datagrid.
I'd like to change the header appearance and I'd also like to create a custom scrollbar.
If only Catalyst would implement a custom datagrid component. I mean the datagrid is a very popular component, isn't it?
Thanks
kristinYou need the password for free apps as well as for paid apps. The only ways that you can control what your child downloads is for you to supervise while the downloading is taking place or by totally restricting download apps with restrictions.
When you enter your password and download content, you have 15 more minutes to continue downloading before you have to enter the password again. So if you download and app - then give the iPad to your child - he or she can continue downloading apps or music or any content for the next 15 minutes without any restrictions. IF you sign out of your account, then the child can no longer download. IMHO - You should NOT give your password to your child. That really is not a good practice.
You can set restrictions on the iPad so that the child cannot download any apps at all. Go to Settings>General>Restrictions>On. Then you will have to enter a passcode for the device which you do not want to forget (if you do, you have to restore the device) so if you do this remember your passcode. You can then go to the apps settings within the restrictions and Enable Restrictions and turn off Installing Apps.
This article will provide more information for you.

Overriding Spark DataGrid item renderer's prepare method - renderer's child is initially null
I am currently using the 4.12.0 SDK. I have a Spark DataGrid setup that makes use of an externally-defined itemRenderer:

Running the debugger shows that this occurs with the first item in the data provider. If I alter the prepare method to check for the existence of imgActions before doing anything, everything works fine after the first item. So I'll have one row in the DataGrid with a missing icon, and all the rest will have icons.
So the question is, is it normal for prepare to run before any children of the item renderer are created? If so, how should I handle this?
Many thanks in advance.A little more info. I added some event handlers to the renderer and the image (for events that I thought would be relevant), and here is the order of events based on trace statements within the handlers:

Setting font style on hover for spark datagrid
I'm trying to skin a Spark datagrid. I have most things sorted by creating a custom skin, but one thing I can't find is how to set the colour of the row's font on hover. I can set the background colour fine, but how would I go about changing the font colour when a user hovers over the row?
ThanksHi
You don’t actually deal with the text that’s displayed in the a datagrid inside of the skin
Look at item renderers for the grid columns. You can style your text or whatever else you would like to display in the grid, in the renderer
Hope that helps a little
If you are still stuck just let me know and I’ll send you some code
Cheers
g
heres some code
NOTE: I am making this up as I sit here so I may be forgetting something. Don’t be surprised if this doesn’t work, but the basic idea is right I think
So in the spark datagrid when you set your column (if you use mxml) this will replace a glob renderer so you can have a different one for each column if you wish.
<s:GridColumn dataField="Status"
headerText="name"
width="37"
itemRenderer="fooRenderer"
/>
Or set a gloabel renderer in the grid def itself
<s:DataGrid itemRenderer=”fooRenderer” />
Then write a custom renderer: fooRenderer.mxml
<?xml version="1.0" encoding="utf-8"?>
<s:GridItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009"

Questions about Spark DataGrid (Header Font Styles, Header Gradient)
Just starting out in 4.5 SDK, and just a tad confused on the Spark DataGrid.
1) Trying to set the font style for just the header, but don't see those properties in the designer....as they appear to apply to every part of the DataGrid.
2) Want to set a linear gradient for the header utilizing two specific colors, alphas and ratios. Not sure where to set them now.
I think that is it for now. From what I have done with it so far, I love it....just obviously not as much user documentation as the MX DataGrid.
Thanks in advance!
BillYou can do per column header renderers by setting the headerRenderer property on the column. But if you want to swap out all the headers, the header renderer has to be specified in the skin. One neat trick you can do is subclass the DataGridSkin and replace the "headerRenderer" declaration. This also works with the other skin parts.
