[flexcoders] AdvancedDataGrid: Disable Dragging Columns

[Paul Whitelock]

In the Adobe documentation it says the following about disabling the
ability to re-arrange columns by dragging:

To disable dragging of all columns in a group, set the
AdvancedDataGridColumnGroup.childrenDragEnabled property to false. To
disable dragging for a single column, set the
AdvancedDataGridColumn.dragEnabled property to false.

However, I don't seem to see any trace of the dragEnabled property
for AdvancedDataGridColumn. I'm probably just missing something
obvious, so can someone point me in the right direction? Thanks!

[flexcoders] Detecting the Access of a Non-Existant Property

[Paul Whitelock]

I thought I read somewhere that there is a way to intercept an
attempted access of a non-existent object property.

For example, suppose an attempt is made to access the property bar
of an object foo which is an instance of the class FooBar (i.e. x
= foo.bar). Further suppose that the property bar does not exist for
foo. Is there a way to define a method in FooBar that will catch the
attempt to access the non-existent property bar and return a value
as if bar actually did exist?

Even something similar to the way the prototype property works would
be helpful (if it is scoped to the instance rather than to the class).
Thanks.

[flexcoders] When are asynchronous events processed?

[Paul Whitelock]

When a response is received from a web service (for example), when is
the listener code executed? The beginning of the next frame? I'm
assuming that currently executing code is not suspended so that an
asynchronous event can be handled, but I was curious as to exactly
when asynchronous events are serviced. Thanks.

[flexcoders] Re: When are asynchronous events processed?

[Paul Whitelock]

Thanks for the explanation. I found the following in Colin Moock's
book and assume that asynchronous events are handled during step 2:

1.Execute Frame 1's frame script. 

2.Wait until the next scheduled frame-render time. While waiting, if
any events are triggered, execute all registered event listeners. 

3.At frame-render time, check if the screen needs updating. The screen
needs updating if any of the following is true: 
* Frame 1 contains changes to the contents of the Stage made manually
in the Flash authoring tool. 
* Code in Frame 1's frame script created new visual content or
modified existing visual content. 
* Code in a listener function executed during Step 2 created new
visual content or modified existing visual content. 

4.If necessary, update the screen to reflect all changes detected in
Step 3. 

5.Repeat Steps 1-4

 Currently executing code will never be suspended in a single-threaded
 environment, which is what Flash is. The asynchronous events are
 handled when your application is idle. Although I don't know how
 exactly the Flash Player does this, I imagine that events are pushed
 into an event queue from where they are processed one by one. So at
 some point, when your network call has returned, its event might go
 into the queue and from there it might get dispatched and subsequently
 handled by your app.
 
 The frame rate has nothing to do with event processing.

Alrighty then, I filed a bug report since the following outputs int:

trace(describeType(uintVar)[EMAIL PROTECTED]());

 I think there is a conceptual distinction between the runtime type of an

 such a value.
 
  
 
 The 'is' operator works on values. A value like 5 'is' both an int, a
 uint, and a Number because it is a legal value in the set of possible
 values for each of these types.
 
  
 
 But I would expect a var declared as
 
  
 
 var u:uint;
 
  
 
 to report itself via describeType() as a uint, just like int and Number
 do. It seems like a bug that it doesn't.

[flexcoders] [Fixed] Flex Weirdness: Verify Errors and E4X

[Paul Whitelock]

Actually, it's more of a surrender than a fix :-)

I finally removed the E4X code and used the old XMLDocument object to
process the XML and the verify errors went away.

I guess that E4X is not quite mature enough to be dependable in all
cases, though it's a bit surprising that the compiler chokes on fairly
simple E4X expressions.

 Hmmm, odd. I wasn't doing anything out of the ordinary. What I did to
 fix the problem in two of the cases was to move the code that creates
 the new event outside of the dispatchEvent method (can't remember
 exactly what I did for the other three or four instances to fix things).
 
  As far as E4x goes, the code you showed may mean that XMLDataItem3 
  may not be in the default namespace.
 
 The root tag has a xmlns declaration, but all of the children are just
 simple tags (not even any attributes). The structure is similar to this:
 
 ?xml version=1.0?
 
 Root xmlns:http://mynamespace;
 
 Result
 XMLDataItem3String1/XMLDataItem3
 XMLDataItem3String2/XMLDataItem3
 XMLDataItem3String3/XMLDataItem3
 /Result
 
 MetaData
 XMLDataItem1String/XMLDataItem1
 XMLDataItem22/XMLDataItem2
 /MetaData
 
 /Root

  For some reason I've been seeing a lot of verify errors on a project

  VerifyError: Error #1025: An invalid register 5 was accessed.
  
  It seems to be related to constructing an event within a

[flexcoders] Re: Flex Weirdness: Verify Errors and E4X

[Paul Whitelock]

 Verify errors generally mean that you fooled the compiler somehow.
 Sometimes, name collisions can fool the compiler.

Hmmm, odd. I wasn't doing anything out of the ordinary. What I did to
fix the problem in two of the cases was to move the code that creates
the new event outside of the dispatchEvent method (can't remember
exactly what I did for the other three or four instances to fix things).

 As far as E4x goes, the code you showed may mean that XMLDataItem3 
 may not be in the default namespace.

The root tag has a xmlns declaration, but all of the children are just
simple tags (not even any attributes). The structure is similar to this:

?xml version=1.0?

Root xmlns:http://mynamespace;

Result
XMLDataItem3String1/XMLDataItem3
XMLDataItem3String2/XMLDataItem3
XMLDataItem3String3/XMLDataItem3
/Result

MetaData
XMLDataItem1String/XMLDataItem1
XMLDataItem22/XMLDataItem2
/MetaData

/Root

 Subject: [flexcoders] Flex Weirdness: Verify Errors and E4X
 
  
 
 For some reason I've been seeing a lot of verify errors on a project
 I'm working on. The error always seems to be:
 
 VerifyError: Error #1025: An invalid register 5 was accessed.
 
 It seems to be related to constructing an event within a
 dispatchEvent call, but I've done this countless times and have
 never seen a VerifyError. So far I've been able to restructure
 the code a bit and it goes away, but this doesn't seem normal. Anyone
 know what might be going on?
 
 The other bit of strangeness is related to E4X. I have something
 similar to the following:
 
 var returnedXML:String = event.result.content as String;
 var myXML:XML = new XML(returnedXML); 
 var xmlNS:Namespace = myXML.namespace();
 default xml namespace = xmlNS;
 
 var dataItem1:String = myXML..XMLDataItem1;
 var dataItem2:Number = Number(myXML..XMLDataItem2);
 
 if (event.result.header.code == someValue) {
 switch (switchVar) {
 case 1:
 var dataItem3:XMLList = myXML..XMLDataItem3;
 break;
 }
 }
 
 The problem is that dataItem3 is always set to null UNLESS I
 recreate the XML object just before the dataItem3 statement, like so:
 
 myXML = new XML(returnedXML);
 var dataItem3:XMLList = myXML..XMLDataItem3;

[flexcoders] Re: How do I get status codes and responses from httpservice faults?

[Paul Whitelock]

When an error occurs a web service will typically return a HTTP error
code with the error message in the body. The problem is that Flex does
not allow you to access the body and just throws a 2032 error. None of
the information from the HTTP response describing the actual error is
available in the fault event.

[flexcoders] Re: error when ttring to create web application which uses HTTP service

[Paul Whitelock]

One thing to check is if the web service is returning an error.

Normally if there is a problem with the request (parameters, etc.) the
web service will return a HTTP error code with the error message in
the body. The problem is that Flex does not allow you to access the
body and just throws a 2032 error.

[flexcoders] How to Clear/Reset Item Renderers When the Data Provider Changes?

[Paul Whitelock]

I have a single row DataGrid with a typed object bound as a data
provider. When data is entered in all columns the handler for
itemEndEvent updates another DataGrid and creates a new empty object
that replaces the previous data provider for the DataGrid.

Even though the data in the new object that replaces the old data
provider is empty, the data that was previously entered in the
DataGrid columns randomly fills one or two of the five columns that
should be empty (it most often happens with two DateFields that are in
custom item renderers). Though data appears in the column cell, if you
try to get the data it comes back as null.

Somehow the DataGrid or the custom item renderer is caching the
previous data and randomly re-displaying it. I've tried setting the
DataGrid data provider to null, then attaching the new empty object as
the data provider, but the ghost data still comes back.

Any ideas how I can clear this old data when I replace the data
provider for the DataGrid so it doesn't reappear in columns that
should be empty? Thanks.

[flexcoders] Re: How to Clear/Reset Item Renderers When the Data Provider Changes?

[Paul Whitelock]

After a bit more investigation it appears that it might be a redraw
issue since the last cell that is clicked is the one where the ghost
data appears. 

Is there a way to force the DataGrid and all custom renderers to
redraw? I've tried calling validateNow() on the DataGrid but it did
not have an effect.

I just tried removing the DataGrid from the display list and then
immediately re-adding it. The ghost data did not go away, so perhaps
it's not a redraw issue.

I can't understand why the last item edited in the grid sticks around
when the data provider is changed.

Shiv,

Thanks for the suggestion. Unfortunately the remote service is an
Amazon Web Service so I don't have any control over what is being sent.

I could create a proxy to intercept a HTTP error, reformat it, and
then pass it along to the Flex app but I was hoping to avoid a proxy
altogether.

I wish that Adobe had documented this so I didn't have to spend the
time just to find out it's not possible to get the body data. Of
course what I wish for the most is that it worked :-)

 The only way I've circumvented this is to tailor the response in the

 exceptions based on user agent. Then on the Flex side to look at this
 special case and throw an exception with the data in the response.
 
  
 
 So in the case where the user agent is flash player (don't remember the
 actual user agent), trap the exception and send back a status code
of 200
 (instead of 500) and in the response, have a way to indicate that
there was

The additional styles include an inner shadow for the content area, a
gradient background for the content area, a tiled image background for
the content area, a tiled image border, and the ability to
independently adjust the transparency of a background image and the
transparency of the content area. 

An interactive design application is included so that you can
experiment with different styles and copy the resulting CSS class
selector to your application.

[flexcoders] Free Image Cropping Component

[Paul Whitelock]

Greetings!

I've just completed developing a component for Flex that enables an
image to be cropped. 

A cropping rectangle is used to select the portion of the image to
retain. The cropping rectangle may be resized using four corner
handles and the rectangle may be repositioned by clicking inside of
the rectangle and dragging. The dimensions of the rectangle may be
unconstrained, or they may be constrained to an aspect ratio.

The component is free and includes full source code (licensed under
the MIT License). You can see an example of the component, read the
documentation and download the component, documentation and source
code here:

 Subject: [flexcoders] Disable Auto-Highlighting in FlexBuilder 3?
 
 I just started working with the FlexBuilder 3 beta and found that it
 highlights (in an ugly cyan color) all instances of a variable name,
 function name, etc. whenever you click in one. Is there any way to
 disable this or change the color? Can't seem to find anything in the
 Eclipse 3.3.1.1 preferences. ...

[flexcoders] Blurring Application Area Beneath TitleWindow (Like an Alert)

[Paul Whitelock]

I need to blur the application area beneath a TitleWindow based on
what's going on in the TitleWindow. The blur effect I'm looking for is
the same that is drawn when an Alert window pops up but the difference
is that I want to be able to programatically disable or enable the
application blur based on a control in the TitleWindow.

Any suggestions how I might accomplish this? Thanks!

[flexcoders] Re: Blurring Application Area Beneath TitleWindow (Like an Alert)

[Paul Whitelock]

Thanks! I just discovered that I can apply/remove a BlurFilter to
Application.application, but I'll check out the PopUpManagerImpl.as to
see how it SHOULD be done :-)

[flexcoders] Keycode for Cmd-V (Paste) on Mac?

[Paul Whitelock]

I'm trying to detect when a paste is performed from the keyboard when
I get a KeyboardEvent. On Windows I just look for event.ctrlKey and
event.keyCode == 86 but this does not work on the Mac. The keyCode
that I get for a CMD-V on a Mac is 0x (charCode = 0).

How do you detect a paste operation from the keyboard on the Mac
(CMD-V)? Thanks!

[flexcoders] ContextMenu: Detecting when Paste is selected

[Paul Whitelock]

I have a TextArea and I need to know whenever a user selects the
Paste option from the ContextMenu. 

I tried creating and adding a ContextMenu to the TextArea, but I can
only add an event listener for MENU_SELECT since I believe you need to
have a reference to the menu item in order to add a MENU_ITEM_SELECT
event listener.

Any idea how I can detect when Paste is selected from a ContextMenu
in a TextArea? Thanks!

[flexcoders] Re: Vista, Eclipse 3.2.2 and a Microsoft Mouse

[Paul Whitelock]

Well the verdict is in -- the Logitech (VX Nano Wireless) mouse wheel
works just fine in Eclipse 3.2 and the Microsoft (Wireless Laser Mouse

I'm using a clean install of Vista, so there are no other drivers
monkeying around behind the scenes that can be blamed. Maybe Microsoft
just doesn't like Java applications ;-)

[flexcoders] Vista, Eclipse 3.2.2 and a Microsoft Mouse

[Paul Whitelock]

My old mouse went to the big cheese factory in the sky and I replaced
it with a Microsoft Wireless Laser Mouse 8000. The problem is that the
scroll wheel does not scroll source code in Eclipse 3.2 (the scroll
wheel works in every application other than Eclipse).

I tried uninstalling the Microsoft IntelliPoint 6.2 driver reverting
to the generic mouse driver and scrolling began to work in Eclipse,
but the next time I booted my machine I was back to a having a
disfunctional scroll wheel.

I did some Googling and apparently there are other people with the
same problem (scroll wheel does not function with a Microsoft mouse in
Eclipse), but I haven't seen any solutions. Has anyone here had the
problem and found a workaround? It's a real pain not to be able to
scroll through my Flex code with the scroll wheel

Thanks!

 I the past I had problems with a Logitech mouse not scrolling in MS

[flexcoders] Re: Programatic Icon

Thanks Mike and Paul for the style solution. I changed my class so
that the icon is controlled by styles rather than using mx_internal. 

The only change I made was to override the styleChanged() function
rather than retrieving style information in updateDisplayList().

[flexcoders] Programatic Icon

[Paul Whitelock]

Would anyone know if there is a way to create an component that can be
used as an icon for any component that accepts an icon?

For example, TitleWindow accepts a titleIcon. I would like to create
an AS3 class that I can instantiate and specify for the TitleWindow's
titleIcon. As conditions change in the window, I'd like to be able to
make a function call to the icon class and have it update the icon
displayed by the TitleWindow. The class would programatically create
the icon (i.e., it would not use an embedded asset).

Ideally the icon component should be able to be used for any component
that accepts an icon.

Any idea if this can be done and if so where I should start looking to
create such a component? Thanks!

Paul

[flexcoders] Re: Programatic Icon

[Paul Whitelock]

Well here's the deal. I've created an simple icon class that draws a
red square like this:

package components {
   
   import mx.skins.ProgrammaticSkin;

   public class Icon extends ProgrammaticSkin {
  
  private var iconColor:uint = 0xFF;
  
  public function Icon()   {
 super();
  }
  
  public function set color(value:uint):void {
 iconColor = value;
 invalidateDisplayList();
  }

  override public function get measuredHeight():Number {
 return 16;
  }
  
  override public function get measuredWidth():Number {
 return 16;
  }

  override protected function
updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void {
 super.updateDisplayList(unscaledWidth, unscaledHeight);
 graphics.beginFill(iconColor, 1);
 graphics.drawRect(0, 0, unscaledWidth, unscaledHeight);
 graphics.endFill();
  }
   }
}

I can place this icon in a Panel like this:

mx:Panel id=myPanel titleIcon={Icon} ... 

So far so good -- the red square is drawn in the top left corner of
the title area and it appears that I can call the color setter
function like this:

myPanel.titleIcon.color = 0x00FF00;

But when I do this the icon color never changes. It appears that the
calling invalidateDisplayList() never results in a call to
updateDisplayList().

Any ideas? 

Paul

[flexcoders] Re: Programatic Icon

[Paul Whitelock]

Unfortunately that did not work. It looks like the setter is not
really being called after all. When I do this:

myPanel.titleIcon.color = 0x00FF00;

What seems to be happening is that it is creating a property called
color just as if myPanel.titleIcon was a generic Object.

I tried creating a doIconColor function (rather than using a setter)
in Icon and calling it like this:

Icon(myPanel.titleIcon).doIconColor(0xFF00FF);

But this results in an TypeError:

TypeError: Error #1034: Type Coercion failed: cannot convert
components::Icon$ to components.Icon.

I can't simply do this:

myPanel.titleIcon.doIconColor(0xFF00FF);

because I get a compile error (call to a possibly undefined method
doIconColor)

So the question now becomes, how do I call a function of my Icon
class? Thanks for any suggestions!

 I can place this icon in a Panel like this:

 So far so good -- the red square is drawn in the top left
corner of
 the title area and it appears that I can call the color setter
 function like this:

 myPanel.titleIcon.color = 0x00FF00;

 But when I do this the icon color never changes. It appears
that the
 calling invalidateDisplayList() never results in a call to
 updateDisplayList().

 Any ideas?

Since this is ProgrammaticSkin, if the size doesn't change, the

I had this same problem.
   
In your color property, call validateDisplayList(); that will

[flexcoders] Re: TitleWindow, Borderskin, and the Move Effect

[Paul Whitelock]

I doubt if anyone is interested in this, but I have some additional
details that I'll record here just in case someone needs it someday.

It appears that if the content of a TitleWindow exceeds the boundaries
of the content area that the content area is filled with the
background color after the borderskin is drawn.

Forms sized at 100% seem to be very aggressive in taking up all
available space, so it's possible that using a Form sized at 100%
could cause the condition where the content area is filled with the
background color after the borderskin is drawn in some situations
(such as during a Move effect).

The solution appears to be to set the backgroundAlpha for the
TitleWindow to zero. This way if the background color fill is
triggered after the borderskin is drawn it will not wipe out the
content area background drawn by the borderskin.

Of course if the borderskin does not draw in the content area, then
this problem may never occur.

I'm not sure why PopUpManager.centerPopUp and/or the Move effect
triggers the background color fill because it doesn't in all cases.
Regardless, setting backgroundAlpha to zero seems to solve the problem
when it occurs.

[flexcoders] Re: White box problem with custom scrollbar skins SOLVED

[Paul Whitelock]

I ran into the scrollbar white box problem also and this posting
helped, but there is a problem with the workaround. While it will work
if the scrollbars are static, if they are dynamically added and removed
then an error will occur when the scrollbars are removed because they
will attempt to remove the child whiteBox which is no longer on the
display list.

Here's the technique that I came up with that is even easier. In your
container add the following event listener to the initialization code:

addEventListener(Event.ADDED, whiteBoxCheck);

And then add the following listener function:

private function whiteBoxCheck(event:Event):void {
 if (event.target.name == whiteBox) {
 FlexShape(event.target).alpha = 0;
 }
}

If you'd rather create a solid color white box, use this:

private function whiteBoxCheck(event:Event):void {
 if (event.target.name == whiteBox) {
 var whiteBox:FlexShape = FlexShape(event.target);
 var g:Graphics = whiteBox.graphics;
 g.beginFill(0xFF);
 g.drawRect(0, 0, whiteBox.width, whiteBox.height);
 g.endFill();
 }
}

Hope this is useful to someone!

[flexcoders] 1 Pixel Gap Between Scrollbar and List Component

[Paul Whitelock]

I have a scrollbar skin that was created in Flash, but I've discovered
a problem when the vertical scrollbar is first displayed in a List
component.

When an item is added to a list causing the vertical scrollbar to be
drawn for the first time, there is a 1 pixel gap between the right
edge of the vertical scrollbar and the right side of the List. If an
additional item is added to the List then the scrollbar is correctly
redrawn flush against the right side of the List. The gap also
disappears if the browser window is resized. This also happens in the
DataGrid, but sometimes the DataGrid will automatically refresh itself
and draw the scrollbar correctly.

Anyone have any idea why the first time a vertical scrollbar is
displayed in a List there is a one pixel gap between the scrollbar and
the component's edge? I don't think it's the skin because the same
scrollbar is drawn correctly in other components.

By the way, I've got the borderStyle set to none but the gap appears
regardless of whether or not the borderStyle is set to none or solid.

Thanks for any suggestions!

Paul

[flexcoders] SOLVED: 1 Pixel Gap Between Scrollbar and List Component

[Paul Whitelock]

Wow! This is like magic! I post a question and suddenly I figure the
answer out myself :-)

The answer, it turns out, did have to do with the skin, but there's a
twist. I was using the Flash skin template supplied by Adobe and the
scrollbar width in the template is 15 pixels. Just on a hunch I tried
redesigning the scrollbar with a width of 16 pixels and the problem
with the 1 pixel gap was solved.

I would suggest that if you are creating a scrollbar using Adobe's
skin template that you consider using a width of 16 pixels instead of
the 15 pixels that Adobe recommends.

[flexcoders] Re: Setting the Font Color for a Selected ComboBox Item

[Paul Whitelock]

Yes, that's what I would have thought too :-)

On the ComboBox close event this is all I'm doing:

if (cb.selectedItem.status == a) cb.setStyle(color, #0B333C);
else cb.setStyle(color, #AA);   

If I select an item in the list that has the color #0B333C (the
default dark gray font color for list items), then everything is fine
(the #AA items in the list stay red and the #0B333C items in the
list stay gray).

If I select a list item that has the red color, then when the
setStyle(color, #AA) executes all of the list items are
rendered in red (#AA).

A odd thing is that if I next select one of the (now red) list items
that should be gray, then when the cb.setStyle(color, #0B333C)
executes the list items are rendered properly (gray items are gray and
red items are red).

It seems it's only when setStyle changes the color to something other
than the default that the itemRenderer no longer has an effect. When
the color is changed back to the default, then the itemRenderer works
again.

Very strange, and very irritating :-)

 Item 
 
 I'm using a ComboBox with an itemRenderer to control the font color of
 items in the dropdown list (items in the dropdown list have their font
 color determined by a property value for each item).
 
 I'd like to have the font color for the selected item in the ComboBox
 match the font color that the item has in the dropdown list. By
 default, this doesn't happen. If I do a setStyle on the ComboBox to
 manually set the selected item's font color to match the font color
 the item has in the list, this works to set the selected item's font
 color, but it also sets the font color for every item in the dropdown
 list (it seems to override the itemRenderer).
 
 Is there a way that I can set the font color for a selected item in a
 ComboBox without impacting the font color (set by an itemRenderer) of
 dropdown list items?
 
 Thanks for any tips!

ComboBox
 Item



 Yes, that's what I would have thought too :-)

 On the ComboBox close event this is all I'm doing:

 if (cb.selectedItem.status == a) cb.setStyle(color, #0B333C);
 else cb.setStyle(color, #AA);

 If I select an item in the list that has the color #0B333C (the
 default dark gray font color for list items), then everything is fine
 (the #AA items in the list stay red and the #0B333C items in the
 list stay gray).

 If I select a list item that has the red color, then when the
 setStyle(color, #AA) executes all of the list items are
 rendered in red (#AA).

 A odd thing is that if I next select one of the (now red) list items
 that should be gray, then when the cb.setStyle(color, #0B333C)
 executes the list items are rendered properly (gray items are gray and
 red items are red).

 It seems it's only when setStyle changes the color to something other
 than the default that the itemRenderer no longer has an effect. When
 the color is changed back to the default, then the itemRenderer works
 again.

 Very strange, and very irritating :-)

[flexcoders] SOLVED: Setting the Font Color for a Selected ComboBox Item

[Paul Whitelock]

I gave up on using MXML to write the list item renderer and instead
wrote it in ActionScript using a TextField. The ComboBox now doesn't
have the problem with setting list items to the color assigned to the
control.

Sometimes MXML is just more trouble than it's worth ;-)

[flexcoders] Disabling Selectable Text for a ComboBox

[Paul Whitelock]

I've got a ComboBox in a Form and for some reason the text is
selectable (i.e., the I-bar cursor is displayed when you move over the
ComboBox and you can drag-select the text displayed for the currently
selected list item). The editable property is not defined, and it
doesn't make a difference if editable is explicitly set to false
(note that it is not possible to type text into the ComboBox, just
select the text that is there). There's no selectable property for a
ComboBox, so I can't use that to disable text selection.

I have ComboBoxes in other Forms that don't have this problem and I
don't see any differences between this ComboBox and the others in my
code. Any ideas on what I can do to make the ComboBox text
non-selectable? Thanks!

Paul

[flexcoders] Re: Disabling Selectable Text for a ComboBox

[Paul Whitelock]

Thanks Ben, that helped a bit. 

I have two ComboBoxes on the Form and each had an enabled=false in
the MXML. However, when I removed the enabled=false from the MXML I
was still getting the i-beam and selectable text.

In my code I'm also programatically changing the enabled state of the
ComboBoxes, so I tried removing the code where the ComboBoxes are
disabled in response to other settings in the form. This time it
worked: the i-beam cursor was gone and the text was no longer
selectable. Of course the ComboBoxes are always enabled now, which is bad.

I did discover something else odd. With the enabled=false gone in
the MXML I can programatically enable and disable the SECOND ComboBox
without it becoming selectable (the first ComboBox still has the
problem when it is programatically disabled and enabled).

Anyone know of a way to disabling/enabling a ComboBox without running
into this problem of the text becoming selectable?

[flexcoders] Re: Disabling Selectable Text for a ComboBox

[Paul Whitelock]

I just discovered why the second ComboBox was not affected -- it's
because I was disabling the ** Form item ** that wraps the ComboBox
and not the ComboBox itself. 

I changed my code so that I enable and disable both ComboBoxes by
setting the enabled property for the Form item rather than for the
ComboBox and now the problem with the selectable text is gone (you can
even set the enabled property for the Form item to false in the MXML
without causing a problem).

One possible drawback that I found in doing this is that the Form
item's label text is dimmed when the Form item is disabled (disabling
only the ComboBox left the Form item's label untouched). Still, it's
better than the alternative of selectable text in the ComboBox.

[flexcoders] Trace Output Stopped Working

[Paul Whitelock]

Yesterday for some mysterious reason the trace() statement stopped
sending data to the console. Event a simple statement like
trace(Here) did nothing (and yes, I was in debug mode). I tried
restarting Eclipse, rebooting the computer, etc. and nothing helped.
Finally I uninstalled the Flex plug-in, trashed Eclipse and all
Eclipse workspace preferences and reinstalled everything cleanly from
scratch. That fixed the problem ... or so I thought.

This morning I started working and tossed a trace statement into some
code I'm working on and again there was no output in the console. The
only thing that shows up is:

[SWF] /cmq/FTApp-debug.swf - 715,093 bytes after decompression

I don't want to have to continually reinstall Eclipse and Flex
everyday as it's a bit time consuming. Anyone have an idea of what's
going on and how to get trace statements working again? Thanks!

No, I'm on a PC. Flex Builder connects to the SWF and I can set

makes a difference.

I think I've figured out how to fix the problem. I first quit Eclipse
and deleted the .metadata folder in my workspace after first making a
copy of it. Next I restarted Eclipse and imported my project (Eclipse
was reset to it's default workspace without the metadata). I tried
debugging the project and trace statements started working again.

I next quit Eclipse and tried copying all of the subfolders in the old
.metadata directory that I saved except for the com.adobe.flexbuilder
subfolders back into the live workspace. When I restarted I was back
to my old configuration and trace was still working.

There must be something in those com.adobe.flexbuilder subfolders that
caused the problem, but I don't know what it is or why it caused the
trace statement to stop functioning. Anyway, it was a lot easier to
fix the problem this way than the other way of re-installing the whole
development environment ;-)

 You can use the as3  PNGEncoder or JPGEncoder libraries at
 http://code.google.com/p/as3corelib/ to do the image format conversion
 within the flex application.  You can post it to a server using either
 remoting, web service, or http service.  Remoting/AMF3 is fastest and
 easiest, but the other methods work well too.  Remoting does not require
 any base64 conversion for the binary data; you can send it across the
 wire as is.
 
  
 
 -Andy
 
  
 
 This is from a previous post I wrote here on flexcoders...
 
  
 
 If you are using AMF3 (RemoteObject), you can serialize binary data
 without any conversion.  If you are trying a standard HTTP post, I would
 use a HTTPService with the method= POST.  Then you have to Base64
 encode the binary data and attach it to the parameters of the http
 service.  On the server side, you will need to decode the base64 encoded
 data back into binary.
 
  
 
 Example:
 
  
 
 mx:HTTPService 
 
 id=httpService
 
showBusyCursor=true
 
useProxy=false
 
method=POST
 
resultFormat=text
 
url=/BinaryData/cf/HTTPImageSave.cfm 
 
 result=onResult('Data Saved via mx:HTTPService') 
 
 fault=onFault(event) /
 
  
 
 private function base64Encode( data : ByteArray ) : String
 
 {
 
 var encoder : Base64Encoder = new Base64Encoder();
 
 encoder.encodeBytes( data );
 
 return encoder.flush();
 
 }
 
  
 
 private function sendData() : void
 
 {
 
 var data : ByteArray = encoder.encode( myPngByteArray );  
 
 var params : Object = { data : base64Encode( data ) };
 
 httpService.send( params );
 
 }
 
  
 
 In ColdFusion, you can decode the base64 data simply by using the
 toBinary function.  Other languages have similar functions as well.  
 
  
 
 Just a FYI... using the JPG instead of PNG requires significantly less
 bandwidth  time to post the data to the server.  Base64 encoding the
 data also increases the size of the data being transferred across the
 wire.  It is much more efficient to use a remoteObject method with
 JPG-compressed data.

[flexcoders] Re: Full Application Reset?

I've found that if you have open windows created by an application you
can't just remove the application from the display list and set it to
null -- the windows will remain open. Also, any listeners that have
been registered will continue to fire even though the application
component is no longer in the display list.

If you are going to use the shell model then it seems to me that
you'll have to make sure to close all open windows created by the
application and unregister listeners prior to dereferencing the
application when logging off.

 or ideally destroyed and re-created. There are portions of this
   application
 that may contain sensitive data, and thus, I'm not willing to
   leave it to
 chance by manually calling custom initialization functions on
each
   component
 / sub-component / etc.
 
  I've thought about recursively iterating through the
Application's
 children, looking for these custom methods and executing them
when
 encountered, but there has got to be a cleaner, simpler way
that I am
 missing. I didn't see much on the mx.core.Application
   documentation that was
 relevant, beyond accessing children properties manually.
 
  Ideas?

[flexcoders] Re: Flex Builder no longer compiles

[Paul Whitelock]

I occasionally have a similar problem in that I'll make changes to
code but when I run or debug the application in Firefox from Flex
Builder it's the same version as the one before the changes were made.

It turns out that for reasons unknown Firefox caches the SWF and
doesn't recognize that it's been changed. If I clear the browser cache
(using the Firefox Web Developer Toolbar plug-in) and run again
everything is fine. It took me a while to figure out what was going
on, but it's now quite easy to solve this problem when it occurs.

Browser caching might not be what is causing your problem, but try
clearing the cache next time you see this problem and see if it helps.

[flexcoders] Problem with Visibility at Beginning of Effect Animation

[Paul Whitelock]

I've been trying to figure out this problem for a few hours now and
I'm not getting anywhere so I figured it's time to ask :-)

I have a simple panel onscreen but with visible=false. When a button
is clicked I want to move the panel from an off screen position to its
current position (or vice versa).

The problem is that sometimes when the panel is being moved on screen
it flashes briefly in the ending (current) position before the
animation starts. It should be hidden until the animation starts at
the off screen position. It's like the effect displays the panel,
moves it off screen, and then animates it to the ending on screen
position. 

Is there any way to prevent this occasional visibility flash from
occurring when the move_on animation begins?

Here are the relevant bits of code:

mx:Move id=move_on xFrom=-200 /   
mx:Move id=move_off xTo=-200 /

mx:Panel id=panel1 visible=false showEffect={move_on}
hideEffect={move_off} /

mx:Button label=+ width=20 click=panel1.visible=true; /
mx:Button label=- width=20 click=panel1.visible=false; /

Thanks for any help!

[flexcoders] Installing Flex 2.0.1 Update

[Paul Whitelock]

What's the deal with installing the 2.0.1 update? Do you need to
uninstall Flex Builder 2.0, install the demo download, and then
re-register with your current serial number? I've got other plug-ins
installed in the Flex Builder version of Eclipse and I'd hate to have
to reinstall everything, but I don't seen any documentation from Adobe
with upgrade instructions.

[flexcoders] Flex 2 Updater Available for Download

[Paul Whitelock]

It can be found here:

http://www.adobe.com/support/flex/downloads_updaters.html

It's not clear to me whether the updater updates Flex Charting and
Flex Data Services. The page says: 

The 2.0.1 updates for these Flex products can be implemented by
installing the full, updated versions of the products.

So I don't know whether you have to install the product from scratch
if you are using Flex Charting and Flex Data Services.

[flexcoders] Re: Flex 2 Updater Available for Download

[Paul Whitelock]

I used the updater to upgrade to 2.0.1 on Windows XP SP2. The update
completed normally and everything seems to work (haven't done much
yet, though). I'm just not sure if I got the updates for Flex Charting
and Flex Data Services with the update or if those products require a
different updater.

[flexcoders] DataGrid Background Anomoly During Vertical Scroll

[Paul Whitelock]

I've got a basic DataGrid inside a VBox which is inside of a
TitleWindow. Sometimes during vertical scrolling the white background
will be drawn *above* the top of the DataGrid component. It's a solid
white filled rectangle about 50 pixels high with a width that matches
the DataGrid's width. The TitleWindow's title is drawn on top of the
white rectangle (probably due to z-depth order). It's almost like a
clipping rectangle is removed allowing the DataGrid to draw its
background outside of the its display area.

Again, it doesn't occur all the time, just at certain scroll
positions. The DataGrid has an itemRenderer, but it's just a simple
mx:Text component, so that shouldn't have anything to do with it.

Anyone know what's going on and how to prevent the DataGrid from
sticking a white rectangle up at some scroll positions? Thanks!

[flexcoders] Re: DataGrid Background Anomoly During Vertical Scroll

[Paul Whitelock]

Yes! That's the problem! After reading through the thread I changed my
code to set cacheAsBitmap=false on the instance of the PopUpWindow
rather than in the MXML component definition. In other words, this:

var crRTEW:ContentRowRTEWindow =
ContentRowRTEWindow(PopUpManager.createPopUp(this, ContentRowRTEWindow));
crRTEW.cacheAsBitmap = false;

And NOT this:

mx:TitleWindow xmlns:mx=http://www.adobe.com/2006/mxml;
xmlns:v=views.* cacheAsBitmap=false ... 

Problem solved!

Thank you very much for finding that thread!!!

[flexcoders] Converting Rich Text to HTML

[Paul Whitelock]

Is there some sample code anywhere that shows how to convert

[flexcoders] Anchor Tags in Rich Text

[Paul Whitelock]

Whenever an anchor tag appears in Rich Text the cursor always changes
to a hand when you move over it and the link is clickable. In some
instances I would like to disable this behavior so that the anchor
text behaves just like normal text (i.e., it is not clickable).

I don't want to remove the anchor tags because they are needed
elsewhere. Is there any way to do disable anchor text behavior in a
component that displays Rich Text (e.g., in a mx:Text component)?

[flexcoders] Re: change markup in richTextEditor

Funny, I must have posted my question about the RichTextEditor
(Converting Rich Text to HTML ) at just about the same time as this
thread was started.

If the methods referred to below are undocumented, where can
information about them be found? Also, since they are undocumented is
there a chance they might be changed or removed in the future thereby
causing code to break?
