[flexcoders] SetStyleAction - clear style?
With respect to styles, you can setStyle() or clearStyle(). There is an effect, SetStyleAction, that allows you to accomplish the setStyle(). Is there some way of accomplishing clearStyle() as an effect? Using a SetStyleAction with a value of null does not work, as the style is still there, and for ints a null style value is often interpreted as 0. At this stage I am thinking of making a custom effect, which seems easy enough, but did not want to re-invent the wheel. -Ryan
[flexcoders] Dragging - ListBase.dragImageOffsets?
ListBase defines two overrideable (protected) getters: dragImage dragImageOffsets It looks to me like the design was to allow subclasses to override the drag image and the offset of it, which is great. However, if you check out ListBase.dragStartHandler, it only ever looks at dragImage. Shouldn't this line: DragManager.doDrag(this, dragSource, event, dragImage, 0, 0, 0.5, dragMoveEnabled); actually be this line: var pt:Point = dragImageOffsets; DragManager.doDrag(this, dragSource, event, dragImage, pt.x, pt.y, 0.5, dragMoveEnabled); I don't even see dragImageOffsets being used anywhere, so I am assuming it was a partially implement design. Thoughts?

[flexcoders] Flex 3 Custom Drag Proxies Broken?
I have a very simple app with a List that displays a custom drag proxy. It works just fine in Flex 2, but in Flex 3 the custom drag proxy does not show. I simply override the protected ListBase.dragImage getter to return my custom drag image (I am pulling the image source out of the currently selected row) like such: var renderer:CustomItemRenderer = this.indexToItemRenderer(this.selectedIndex) as CustomItemRenderer; var actualImage:Image = renderer.thumbImage; var dragProxy:Image = new Image(); dragProxy.source = actualImage.source; dragProxy.setActualSize(actualImage.width, actualImage.height); return dragProxy; I see the custom drag proxy moving around fine in Flex 2, but nothing is drawn in Flex 3. I do get the drag indicator (red X when not over a drop target), and when I drop the image it does show up. It is just that the custom drag proxy does not show while dragging. Any ideas?
[flexcoders] Re: DateField FlexEvent.ENTER Event?
I got it working. The final solution is: 1. override focusInHandler leave defaultButtonEnabled = true 2. when the drop down (date picker in this case) is shown, set defaultButtonEnabled = false when it is shown, true otherwise Just my opinion, but I think this should have been the implementation for ComboBase to begin with. The only reason I can see wanting to disable the defaut button is so that when a drop down (date picker or list) is displayed, ENTER works against that drop down. Otherwise, ENTER should cause default button processing. Anyway my change makes it work this way now. --- In flexcoders@yahoogroups.com, "rkettrey" <[EMAIL PROTECTED]> wrote: > > Thanks for the reply, it got me going in the right direction. > Instead of my original code, I simply overrode DataField's > focusInHandler (actually implemented in ComboBase) and changed the > line: > > fm.defaultButtonEnabled = false; > > to > > fm.defaultButtonEnabled = true; > > Now pressing ENTER in the DateField works, with one caveat.

[flexcoders] Re: DateField FlexEvent.ENTER Event?
Thanks for the reply, it got me going in the right direction. Instead of my original code, I simply overrode DataField's focusInHandler (actually implemented in ComboBase) and changed the line: fm.defaultButtonEnabled = false; to fm.defaultButtonEnabled = true; Now pressing ENTER in the DateField works, with one caveat. When the date picker is up, ENTER should only make the picker close. This case is being checked currently in ComboBase.keyDownHandler, and I was expecting the existing call in that function to event.stopPropogation (after checking the picker is up and closing it) would stop the ENTER key from being process by the focus sub- system. It does not apparently. I also tried overriding it and changing it to event.stopImmediatePropogation for the heck of it, but it does the same thing. What is going on here and any ideas how I can make it eat the event from the focusManager point of view when the picker is up? --- In flexcoders@yahoogroups.com, "Alex Harui" <[EMAIL PROTECTED]> wrote: > > defaultButtonEnabled also need to be changed. > > > > > > From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On > Behalf Of rkettrey > Sent: Wednesday, October 17, 2007 1:24 PM > To: flexcoders@yahoogroups.com > Subject: [flexcoders] DateField FlexEvent.ENTER Event? > > > > TextInput controls will broadcast the FlexEvent.ENTER event when the > enter key is pressed to simulate the default button being pressed for a > form. > > I'd like this same thing to happen on my DateFields.

[flexcoders] DateField FlexEvent.ENTER Event?
TextInput controls will broadcast the FlexEvent.ENTER event when the enter key is pressed to simulate the default button being pressed for a form. I'd like this same thing to happen on my DateFields. I know that DateField wants to handle the enter key to do its parsing and closing of the "drop down" (inherits from ComboBase for the date picker), which is fine. If it is only handling parsing, though, I would like the control to broadcast the enter event. After looking at what the TextInput does, I overrode the keyDownHandler function in DateField where it handles the ENTER key. At the end of the ENTER key handling scope I added: dispatchEvent(new FlexEvent(FlexEvent.ENTER)); Everything compiles and it appears to broadcast the event. However, the default button handling does not occur. Any thoughts?
