[flexcoders] Datagrid sorting and ArrayCollection Filtering
Hello,
I am having a problem related to sorting by a certain column and
applying a Filter on an array collection. I'm not sure if this is a bug
or not.
I have an array collection that has a filter function associated to it.
I have a datagrid that is binded to this array collection. Two of the
datagrid columns however do not have a dataField defined, but they do
have a labelFunction since they are a combination of some of the
properties in the arraycollection.
The problem is if I am sorting by the second data grid column that
doesn't have a dataField defined, and then reissue a refresh() on the
array collection, the sort arrow appears next to the wrong columns.
See the attached example for behavior:
I have a data grid and I click on the header to sort by "Name and
grade" column. I then hit the "Apply Filter By name button" and now the
sort arrow appears next to the "Name and Age" column.
Thanks

[flexcoders] Re: ImageSnapshot and PopUpManager
Thanks it worked. This is what I ended up doing
private function captureImage() : void
{
var sn : ImageSnapshot;
sn =
ImageSnapshot.captureImage(this.systemManager.getTopLevelRoot(),100,new
PNGEncoder());
var file:FileReference = new FileReference();
file.save(sn.data, "captured.png");
}

[flexcoders] ImageSnapshot and PopUpManager
Hi, I have an application that has several windows that were created using the PopUpManager. I would like the user to be able to take a screenshot of the the app so I am using the ImageSnapshot class. The application is being captured but none of the pop up windows are showing up. Is there any way I can achieve this? I have attached an example of the problem. You will need to ensure that the project is set to require Flash Player Version 10.0 in the flex compiler options. To see the problem click on 'Pop up box' then click on 'Capture Image' Thanks in advance http://www.adobe.com/2006/mxml"; layout="absolute">

[flexcoders] Hand Cursor and datagrid
I have a datagrid and for each row I would like to show the hand cursor (to indicate to users that it is clickable). I've tried setting useHandCursor and buttonMode to true on the datagrid but that makes the entire datagrid show the hand cursor. Has anyone done this before? Is there a way to do this?
[flexcoders] Re: HTTPService Busy Cursor
Thanks. But this example assumes that I have full control over when I want to show and hide the cursors. The HTTPService, however will show and hide the busy cursor for me automatically (hence the property showBusyCursor). I guess I would have to set that property to false and then manually show the cursor before I issue my send and then in my result or fault methods I would have to hide the cursor. I was just hoping that there was a cleaner and more general solution to this. --- In flexcoders@yahoogroups.com, "valdhor" wrote: > > Check out > http://www.switchonthecode.com/tutorials/flex-custom-cursor-tutorial > > > --- In flexcoders@yahoogroups.com, "shafram" wrote: > > > > I am using the mx:HTTPService from Flex and it has a showBusyCursor > > property that I set to true: > > > > > showBusyCursor="true" > > result="handleResult(event)" > > fault="handleFault(event)" > > method="GET" > > url="http://someurl/"; > > /> > > > > When the HttpService is issued a send request, the busy cursor is > > shown as an animated clock.

I am using the mx:HTTPService from Flex and it has a showBusyCursor property that I set to true: http://someurl/"; /> When the HttpService is issued a send request, the busy cursor is shown as an animated clock. I would like to use a custom gif. Is there any easy way to do this? Thanks

Thanks for the responses. As a follow on question, is there a way to control the spacing in between the lines (for example single space, double space) When the word wraps there is too much of a gap in between the lines, and it would be nice to control that spacing.

[flexcoders] Re: DataTip targets
Hi thanks, yes I've set showDataTipTargets="true", but this will only
cause the targets to appear when the user mouses over the graph. Is
there a way to always have it appear? And is it possible to have it
appear for bars that don't render in the graph?
I'm trying to find the tip renderer for the ColumnSeries but I don't
see it. Can you give an example?
Thanks.

[flexcoders] DataTip targets
Hi, I've been searching around for any example to do this but I haven't found anything so far I have a Cartesian chart with a column series. Some of the bars don't render on the chart because their values are very small. However showing the datatips for these bars is still useful. The only problem is that there is no indication that there's a datatip unless the user rolls their mouse over the graph where they may see a datatip for one of the very small bars. My question is, is it possible to always show just the data tip target for the bars that don't render on the graph? Thanks

[flexcoders] Wierd behaviour with selectedItem on Datagrid
Hello I am encountering a strange problem when I try to select an item after an initial sort order has been provided. In this example, I have 5 items with all the same count. My initial sorting is on the count field. Once the initial sort has been set, I programmatically select the 4th item in my array which is Letter "D". If I then try to click on Letter "A" which is right above "D", The alert box will display "D" not "A" in Flex 3. In flex 2 the event.target.selectedItem is null and an exception is thrown. Here is the source code. Am I doing something wrong or is this a bug in flex? http://www.adobe.com/2006/mxml"; layout="absolute" creationComplete="cc()">

[flexcoders] Cairngorm and Menu Object
Hi, I have a catesian chart that allows you to click on a single bar which will display a Menu object. Now inside my mxml that contains this chart there is an itemClick event and in there is where I create my menu and do a menu.show(). In order to build this menu there is several business logic involved depending on which bar was selected and so on... Is there any better approach to creating the Menu for instance in a Command class? Any feedback would be appreciated.
[flexcoders] Setting canDropLabels=true may drop all labels on a cartesian chart
Hi, I have a Cartesian chart and I have the horizontal axis renderer set to canDropLabels to true. I am reading my category axis from a file and in certain cases when I resize my window, all labels seem to be dropped. If I set my category axis from inside my flex app instead of relying on the xml file, it seems to drop labels just fine. Here is some sample code showing the problem I've tried this in flex 2.01 hotfix 3. Is there something I'm doing wrong? Is this a bug in flex?

[flexcoders] Controling item selected in a datagrid
Hello, I have a datagrid displaying data, but my last column is suppose to display an image and when this image is clicked, I'm suppose to popup a menu that will allow the user to change the color of the text in that row (kind of like marking that row as read). As such whenever the user clicks on that image, I simply want to catch the item click event without actually displaying that row as selected. For example, the user selects a row by clicking on any of the columns displaying text and that row becomes highlighted. Then on another row they click on the column displaying the image to popup the menu. I don't want to have that row selected, I want to keep the previous row selected. I've tried to set the datagrid's selected item back to the previous row, if I see that the column selected was the image, but I'm hoping that there's a better solution since you can clearly see that the previous row is being re-selected. Thanks in advance.
