[flexcoders] Setting fontWeight on a DataGrid Row
Hello,
Is there a nice easy way to set the font weight of each cell in a
DataGrid *row* (not column)? I can set (e.g.) the backgroundColor by
using something like:
dg.setPropertiesAt(1, {backgroundColor:0xFF})
But setting fontWeight has no effect. I could loop through each cell
individually within the row an set the fontWeight on that, but this
seems like a long-winded way of doing it.
Any suggestions?
Thanks,
Tim.

[flexcoders] DataGrid Editable Header Renderer
Hello, I'm attempting to create a custom headerRenderer for a DataGrid which will allow the user to edit the column name (headerText) in exactly the same way as the standard editable DataGrid cellRenderer. Before I spend any more time on it, does anyone have an example of such a thing hanging around, or can point me in the right direction?

That > ways I can get the reference of individual tabs. I'd already thought about doing something like this but wasn't sure about spending the time doing it.

[flexcoders] Styling individual tabs in a TabNavigator
Hello,
Is it possible to style the colours of individual tabs in a tab
navigator? For example, in the following code I'm attempting create a
TabNavigator with three tabs, each of a different colour, but having no
joy... I can style all tabs by using the Tab{} declaration, but I'm
looking for a way to style each tab seperatly.
http://www.macromedia.com/2003/mxml";>
.tab1 {
fill-colors: #99cc00, #ccff66;
selected-fill-colors: #00cc00, #66ff66;
}
.tab2 {
fill-colors: #FFF04B, #CC;
selected-fill-colors: #E9C414, #CC;
}
.tab3 {
fill-colors: #8AC7D2, #CBEEF1;
selected-fill-colors: #00A3B2, #CBEEF1;
}
Any suggestions/solutions?
Thanks,
Tim.

[flexcoders] Auto-scroll on TileList
Hello, I have a TileList component which I add items to via a drag/drop operation; this is all working fine. The problem I'm having is that when the item has been dropped onto the TileList, it appears the resetScrollPositions() function is automatically called and the TileList automatically scrolls back to the beginning. How can I get this to scroll to the position that the new item has been added?

RE: [flexcoders] Disappearing images in custom cell renderer
Manish, > What happens if you set 'source' directly instead of using > binding? Try it. Unfortunately, because of the way the data is fetched from the server, the data required (i.e. the thumbnail URL) may not be back before the component is initialised, hence the binding. But your suggestion did point me in the direction of a fix... It seems that there was a problem initially setting the source as effectively a non-existant image and then overwriting that when the "proper" URL was actually retrieved. What I ended up doing was not initially specifying a source for the tag, but then when the appropriate asset data had been retrieved from the server, using an explicit img.load() call to load the thumbnail. So now the image source gets (re)set when and only when the effective "source" is both a non-empty string and is different to the current source. Seems to be doing the job!

[flexcoders] Disappearing images in custom cell renderer
What is it with me and images at the moment...?
Anyway, I'm having trouble with displaying thumbnails in a custom cell
renderer within a TileList component. The code for the cell renderer is
displayed below (AssetThumbnail.mxml) and the line that defines the
TileList is also shown (ThumbnailView.mxml).
When the user clicks on a given item, a search is performed which
populates the aAssetSearch array with the appropriate Asset instances to
display thumbnails for; this is then bound to the TileList as the
dataProvider. When the list of images are displayed, one of the
following happens:
1. the thumbnail displays correctly;
2. displays correctly, then after a second or so vanishes;
3. nothing is displayed.
My guess is that #3 is actually #2 happening very quickly so the "in
between" redraw doesn't actually happen. I can often get the missing
images to redisplay by performing a new search and then going back to
the original, at which point the original search's assets have already
been pulled back from the database and cached. Sometimes this can be
achieved by scrolling the TileList up and down to redraw the appropriate
cells. Neither of these two methods either works 100% of the time, and
quite often the cells remain blank.
This pointed me towards the thought that there was something strange
going on with the Asset instances that meant they weren't returning the
appropriate URL for the image, or it was being returned and then reset.
However, I tried adding a trace into the dynamic "get" function for the
thumbnail URL (see code for Asset.as below) and all looks fine (i.e. it
returned the URL correctly).
Has anyone got any idea why this may be happening?
Thanks,
Tim.

[flexcoders] Image not being resized in mx:Image tag
Hello, I'm having trouble with images not resizing to fit the tag specfied (and also with SWFs not resizing to fit the appropriate ). An example can be seen at the following URL, where the image (green boxes) *should* be contained within the grey box top right: http://kryten.rawnet.com/flex/flex-corrupt.html#lgimage The MXML to output the image is as follows: Extra information: - "assetURL" is a simple string like http://server/path/ - "asset" is an instance of an AS class - "asset.assetURL" is a dynamic property of the "asset" instance, with an appropriate changeEvent defined Any idea why this should be the case?

[flexcoders] Serious corruption in Flex-generated SWF
Morning all, We're having severe issues with components within a Flex-generated SWF being displayed corrupt. The problem is that this doesn't happen all the time, and I can't seem to find a reproducable method of "forcing" the corruption. Examples of the sort of thing we're seeing can be seen here: http://kryten.rawnet.com/flex/flex-corrupt.html All corruption occurs at the same time (i.e. when one thing goes, they all go), but not all components are affected. The problem only seems to affect components displayed within an accordian, but again not all contained components are effected. If you look at example 1 on the page above, the items under "edit existing..." are corrupt, whereas those under the "create new..." heading are displayed fine. Does anyone have any idea what's going on here? Has anyone seen this before?

[flexcoders] Pre-selecting Tree nodes
Hello,
Does anyone have an example of pre-selecting nodes in a Tree component
based on the data item associated with that node? I'm tearing my hair
out here...
Example: I have the following files (tree.xml and tree.mxml) -- on
initialisation (or button click etc) I would like the nodes with the
data value of 39, 40 and 47 ("Collections", "Kettles" and "Juicers") to
be selected, and the tree open at the appropriate places. I've pasted
the test code I have in place.
What happens with the test code below is that on the first click of the
"populate" button (without manually expanding any of the tree nodes
first), nothing happens. If I then expand both the root ("Assets") node
and the "Brand" node below it, click the button again will open up the
correct nodes but will mark the root node as selected. After these
nodes have been displayed, I can close all nodes and then the populate()
works as expected in opening the correct nodes, but again selects on the
root node.
Any help greatly appreciated!
Cheers,
Tim.

Even when setting the value of the cells in each new row to
something
other than "" I still couldn't edit the cells without first
creating a
new column. Additionally, the value of the cells wasn't
displayed until
after the new row had been added.
In the end I had to do two things to get it to work, the first
of which
is a temendous hack that I really don't like. Because I
couldn't edit
cell information until after a new columnn had been created,
when adding
a new row I forced creation and then immediate deletion of a new
column:
// new "row" added to the patta provider in the lines above
myDataGrid.addColumn(new DataGridColumn("temp"));
myDataGrid.removeColumnAt(myDataGrid.columnCount-1);
Additionally, as Manish suggested, I had to give the initial
value of
each cell a non-empty string value (a single space) or even
after
editing the field, the label wouldn't be shown until after a new
row is
created.
As I said, hacky and not nice, but at least I have it working
they way I
expected it should! So the question is -- what's going on here?
Bug?
Tim.

[flexcoders] Dynamically poplulating an editable DataGrid
Evening all, I'm having some issues with an editable data grid. Basically it starts of as an empty grid and the user can populate it by adding columns and rows, but it doesn't appear to be working as I expect it to. I can add columns using dg.addColumn() absolutely fine, and they are displayed as expected. However, when I add a new row (by adding a new Object to the dataProvier array), I can't actually edit the field until I've added another column. Once I've done this, the new row can be edited normally. I can also "force" the row to be editable by tabbing from one (already editable) row to a newly created one. Additionally, after editing a cell, it appears that sometimes the underlying data model is updated but the display is not updated. For example, using the code below, if I edit the one and only cell that's automatically created and the move the focus somewhere else, the new value isn't displayed (although I can get it back by re-editing the cell). Can anyone shed some light on this situation, or recommend another way of going about things? Thanks, Tim. PS. The code I'm testing with is as below: http://www.macromedia.com/2003/mxml";> -- --- Badpen Tech - CF and web-tech: http://tech.badpen.com/ --- RAWNET LTD - independent digital media agency "We are big, we are funny and we are clever!"

[flexcoders] Handling "status" event types with Remoting/CFCs
Afternoon,
I have a number of CFCs which I'm accessing through RemoteObject calls.
I've noticed that if CodlFusion throws an error (built-in or custom)
then the reponse comes back with an event type of "Status", which isn't
handled by either the result or fault handlers specified for the
callback.
I'm using the following to set up the remote call:
And then this ActionScript to call it:
function getSlideResult(event:Object) { ... }
function getSlideFault(event:Object) { ... }
Function getSlide(slideid:Number) {
var call = rSlide.getSlide({slideid:slideid});
call.resultHandler = Delegate.create(this, getSlideResult);
call.faultHandler = Delegate.create(this, getSlideFault);
}
If an error occurs (in this case, the item we're trying to get doesn't
exist so a custom error is thrown) then neither getSlideResult or
getSlideFault fire. I get the following information back from the
NetConn debugger:
DebugId: 0
EventType: "Status"
MovieUrl: "http://localhost:8700/flex/remote.mxml.swf";
Protocol: "http"
Source: "Client"
Time: 1114687271399
Date (object #1)
."Thu Apr 28 12:21:11 GMT+0100 2005"
Status (object #2)
.code: "SERVER.PROCESSING"
.description: "Service threw an exception during method invocation:
[Slide.GetSlide.SlideNotFound] The requested slide (ID 6) cannot be
found."
.details: "coldfusion.runtime.CustomException:
[Slide.GetSlide.SlideNotFound] The requested slide (ID 6) cannot be
found." [long error report snipped]
Is there any way of specifying a handler for these "status" events?
Cheers,
Tim.

[flexcoders] Disappearing struct from CFC using RemoteObject
Hello, I'm slowly going crazy here. I'm trying to make a simple RemoteObject call to a ColdFusion CFC using Flash Remoting. Nothing exciting -- pass a couple of vars, get a structure containing user data back. Whenever I try and return a type of struct (and only struct, as far as I can see) from the CFC, things go a little strange and I don't get the results I expect back (an object containing thye keys: sessionid, userid and valid). In the net conection debugger I get back the following, which looks correct to me: DebugId: 0 EventType: "Result" MovieUrl: "http://localhost:/flex/test.mxml.swf"; Protocol: "http" Source: "Client" Time: 1114533397451 Date (object #1) ."Tue Apr 26 17:36:37 GMT+0100 2005" Result (object #2) .SESSIONID: "7F3D91BB-8A11-29EE-1B5963898741A372" .USERID: 1 .VALID: "TRUE" However, the network monitor only shows this: [array] : length[Number] : 0 >From some further poking, when checking the return data, event.result is undefined; the private member data __result *does* contain the correct data, but I can't access this using event.result. Does anyone have an idea what's going on here?
