[flexcoders] Printing in IE Crashes IE But Firefox Ok
I am adding a very simple component. It crashes IE, but it prints fine in
Firefox. Here is the component:
?xml version=1.0 encoding=utf-8?
mx:VBox xmlns:mx=http://www.adobe.com/2006/mxml;
mx:Label text=Patrick is testing here/
/mx:VBox
HERE IS THE PRINT CODE:
printJob.start();
for each(var page:Page in pages)
{
printJob.addObject(page);
}
printJob.send();
[flexcoders] TileList Item Spacing
I need to increase the spacing horizontally and vertically between the items in my TileList. I don't see how to do it. Please advise.
[flexcoders] How do you create a mask with a semi transparent background color?
I created a mask that covers an image completely except for a rectangle in the middle. It works like I want it to, but I can't apply a color to the non masked area around the rectangle in the middle. I also want to apply an alpha to that color so the image can be seen but it will be grayed out. I am trying to create an effect like the photo crop feature on picnik.com.
[flexcoders] Why empty rows are showing in datagrid
My datagrid shows alternating colors for rows that are empty (there is no data for that row). My dataprovider has only one data item in it. Why are the rows showing?
[flexcoders] Crossdomain.xml allow-access-from domain Question

[flexcoders] Creating a Modal Window
Is there an easy way to create a modal window without using the popup manager? I want to gray out every window but the current one so no mouse clicks or keyboard input can happen except this window. I have tried using the PopUpManager with a Canvas, but Canvas in the PopUpManager turns the background to transparent. The whole screen looks grayed out. I am using the Canvas to draw on over the top of another component.
[flexcoders] FlexPrintJob doesn't print
I have noticed while playing around with FlexPrintJob that sometimes it won't print. I call printJob.start() , printJob.addObject() and printJob.send(). Has anyone else seen this? The print dialog comes up and I click the print button, but it doesn't actually get sent to the printer.
[flexcoders] Print Image and Text Problem
I am trying to print a text header with an image control. I scale the

a bitmap. Here is the code:

[flexcoders] Get TextArea Line Contents
I wish there was a method to get the text for each line in a TextArea control. I have some text that I don't want to get broken up by word wrapping. Is there a way to access the content of each line of text in a TextArea? I have this line of text: Here is a whole bunch of text [ Images Only ] Sometimes it wraps and breaks up [Images Only] like this: Here is a whole bunch of text [ Images Only ] If I could access the text, I could put a newline to force it to wrap where I need it to wrap. Maybe there is a better control for this situation.

[flexcoders] Re: ComboBox Disable Drop Down Items
There is a weird thing happening here. Maybe someone could explain
it. I changed back to having a disabledFunction variable instead of
having the function in this class. I am trying to set the
disabledFunction like this:
var dropDown:DisabledItemList = DisabledItemList
(collectionCombo.dropdown);
dropDown.disabledFunction = disabledCollectionItem;
It sets it but then in the DisabledItemList the disabledFunction
turns to null. Is this because it is a factory? I know I am setting
this function on a sub component of ComboBox and that it isn't the
best way, but it should work.

[flexcoders] Changing Parents
I have an image viewer that I would like to go full screen. I now have my app taking up the full screen, but I need the image viewer window to become the size of the app window. The image viewer is a child of a child of a child of the Application. I am calling application.addChild (imageViewer) to get this to go full screen, but when I want to go back to the normal view, I do a application.removeChild(imageViewer) and I want to add it back to the parent it had before. But that doesn't work. How can I change parents of a component without causing havoc?
[flexcoders] Re: Changing Parents
Forgive me, but how do you remove the child from the stage? Did you do the following (using my example): //Go to full screen app.addChild(imageViewer); subcomponent.removeChild(imageViewer); //Go to normal screen subcomponent.addChild(imageViewer); app.removeChild(imageViewer); The problem I am having is putting the imageViewer back into the subcomponent. It does not reappear in the subcomponent. --- In flexcoders@yahoogroups.com, Brian Deitte [EMAIL PROTECTED] wrote: I did this recently, and it didn't cause havoc. What are seeing that goes wrong? I had two issues that I did needed to fix. One is that you have to remember to remove the child from the stage before adding it back to the application. The second is that the bindings were reexecuted when added back to the application, which I worked around by checking for the same value in the places I was observing bindings. -Brian On Thu, Aug 7, 2008 at 11:53 AM, wwwpl [EMAIL PROTECTED] wrote: I have an image viewer that I would like to go full screen.

[flexcoders] Browser Title Changes on Refresh
We set the browser title in our html-template for our site and it works great. We use a view stack component to manager our pages in our site.

[flexcoders] ListBox scrollToIndex scrolling item out of view
I am using a variableRowHeight list box. If you click on an item, it expands to twice the height. I had to put in a call to scrollToIndex because once the last visible item on the bottom was expanded, it would only show half of the item. Now there is another bug.

[flexcoders] TitleWindow (Popup) Resize Problem
I have a dialog box with a text field in it. The text field can be set with text that wraps. So the size of the text field is unknown.

I set autolayout=true, but that didn't help. I have tried invalidateSize() after setting the text etc. without success.

I am developing a Flex application where I need to do some resize effects. I have 2 VBoxs side by side. They need to resize when a user clicks a button. I have been using states to do the resize effects, but I can not get it to look nice. I have tried a lot of effects and other things, but it doesn't look good. So I started to create a custom component that is based on the Accordion tween effects. Now it looks nice, but I am wondering why I could not get it to look nice with the resize or move effects. I applied a lot of the animation optimizations that I have found.
[flexcoders] RSL Error 2032 on Corporate Network
We have some users who are getting an RSL error 2032 on their coporate network. We have many thousands of users who are not having problems. I noticed in the documentation that it says that if you use RSLs, you need to have a crossdomain.xml file on the same domain. Currently we do not have a crossdomain.xml file. We would have to leave the cross domain wide open to allow all users to connect. That doesn't sound like a good solution. We do not specify an rsl-url on the shared-library-path option. We require the user to upgrade to version 9,0,115 of the flash player. Other users on coporate networks report that the loading box shows up to load our app, but it slowly increases progress to half way and then stops without an error. Does anyone have advice on this problem?

We would like to get rid of callbacks in our project. Recently I had to change about 15 different callback function signatures.
