Re: [flexcoders] How do you load a page in a tab
As far as I know, this is not a supported action. You cannot choose to open a link in a tab, as it's not standard to have tabs in a browser. Even if this is very common now. It's up to the user to choose the option, for exemple, to force new windows to open in a tab. Maybe I'm wrong.. let's see what will think other people.

[flexcoders] PopUpMenuButton like a combobox
Hello, I have hierarchical data nicely binding to a PopUpMenuButton which I'm using on form. I've managed to create a handler that changes the label when an item is selected but can't seem to figure out how to pre-set the value of the PopUpMenuButton when the user wants to edit an existing record. Try something like this but it didn't work Menu(categoryPopUpMenuButton.popUp).selectedItem = _posting.category; Thanks, Arshak
[flexcoders] Advanced datagrid dataprovider changing error
Hi I am trying to change the dataprovider of a
advanced datagrid where I am using HierarchicalData
as data provider. My ADG code is this:
mx:AdvancedDataGrid width=20% height=50%
mx:dataProvider
mx:HierarchicalData id=HD source={dpHierarchy}/
/mx:dataProvider
mx:columns
mx:AdvancedDataGridColumn dataField=Region/
/mx:columns
/mx:AdvancedDataGrid
I tried to switch the dataprovider as HD.source = anotherArray;
But it did not work. Here I am attaching the code if that
helps to find the mistake.

Hi,
Try calling validateNow on the DG after setting the DP source.
Or you might have to actually change the DP to a new HierarchicalData.

[flexcoders] Re: Success!!! But I still need help!! (RE: Custom scrolling with TileList)
I realize this post is over 2 years old, but I'm having a similar problem, and I can't find much info out there. I'm using a TileList control, and I've added buttons to the top and bottom and removed the scroll bars. I'd like buttons to smoothly scroll in the new images, but right now it just flashes to the new timesI'd like something like the way the image scroll bar works on pictobrowser: http://www.db798.com/pictobrowser/samples.html But I'm not sure where to place the transition effects, or which effects to use. Any information or tips would be really helpful. Thanks, Rob --- In flexcoders@yahoogroups.com, qnotemedia [EMAIL PROTECTED] wrote: Well - never received a reply to this thread, but I've figured out how to get the look, feel, and interactivity that I wanted via lots of nested Canvas', HBox's, VBox's, etc...Here's what I've basically done. Again, the goal was to make a vertical TileList with component itemRenderer, that scrolls smoothly, and rather than using the default scrollbar, create my own scrollDown and scrollUp buttons (with no scrollbar actually available - just the buttons). - I have a TileList of course, and its height is dynamically set to the number of items in the itemRenderer * 125 (an item's height). scrollingPolicy is disabled. With 75 items that makes its height. - itemRenderer consists of an image and label. The images can be large - width of 640 - and are scaled down via maxWidth/Height. - The TileList is within a VBox with scrollingPolicy disabled. - An Up/Down button calls a function that sets the verticalScrollPosition of the VBox to += 20 or -= 20 via buttonDown with autorepeat. This creates the effect of a nice smooth scroll! PROBLEM I need help with now: Performance has become an issue. When the TileList contains 75 thumbnails, that makes its height nearly 10,000 (75*125)! The problem is that, to Flex, the entire list is being displayed, whereas when you normally display a smaller sized TileList, items are not loaded until they are physically displayed by the user. When it first loads, it really chokes up cause its calling to load every single thumbnail in the list all at the same time. Is there any way to fix this!? - Chris
[flexcoders] Foreign Keyboard Mappings
I have a flash application that's being used in other countries. I'm having reports that certain keys from certain keyboards are not getting translated properly. My application uses a custom equation editor that I wrote. I'm using key up and key down handlers to capture key strokes. I can't believe the flash doesn't support character translations out of the box. I know some people out there us a hidden TextField to capture the translated text, but I really don't want to do there. I suspect that will mess up a lot of my focus code and cursor movement code. Has anyone tackled this another way? One idea I had was to somehow come up with a keyboard mapping application, that would require the user to learn the keys. I would then store some sort of a lookup table inside a shared object. I'm not sure what the interface would look like, but it's an idea. Any other ideas would be appreciated.

[flexcoders] Re: Accessing a Basic Auth protected site from flex.
Thank you. This explains a lot. I had seen posts on how to do this but
nowhere did I
stumble on the info you provided. Specifically, that 9.0.115.0 was a version
that blocks
the Authorization header regardless of what you do. Guess what version I've
been
running? So, I will update to a more recent version and give this a try.
Unfortunately while this will work for some basic auth protected systems I have
to figure
out what to do about network devices I'm connecting to that can't have any
crossdomain
file added to them. For those I may just end up setting up a proxy using
something like
mod_proxy.
I will post the results after I try this out.

Hello Keith!
Try this:

mx:CheckBox click={someComponent.prop=event.target.selected} /
event.target will point to the component that was clicked.

[flexcoders] Export high res png from flex
Hey Everyone, I'm trying to come up with a clever way to export a high res (300dpi) .png image from flex to be saved on my server and later printed. The initial bitmapdata is being taken from a 400x400 pixel Canvas container. I then use the PNGEncoder class to turn the bitmapdata into a bytearray and then send it on to the server. The issue is that the .png output is at 400x400 pixels. The contents of the Canvas are all in .swf (vector) format so I thought simply setting the scaleX/Y properties to 4 prior to exporting might do the trick, but I have not yet had any luck with this. Any ideas would be greatly appreciated. Thanks, Kyle

[flexcoders] Re: Export high res png from flex
Hi Kyle - I don't think the scaleX/Y actually changes the size of the canvas, so what you want might want to try is actually resizing the container. If for some reason you can't do that, maybe you could copy the contents into a new canvas that is not visible then resize that one. I'm curious how you will get the byteArray to the server though...I've been trying to do this using a REST upload interface, and I haven't had any luck.
