@DJNRLN: sure why not? I say a WindowShade within a WindowShade is possible.

I am starting to work with WindowShades, a project i am working on would like to have WindowShade2 views within an outer WindowShade2 view.

For example Ice Cream would contain a multiple sub-Views that are defined as windowShade2. the sub-views could be for toppings and cone styles.

is it possible to have WindowShade views within a WindowShade?

thanks

thanks for your answer. I have solved this question, but the solved method isn’t clever.
the reason of checkbox’s icon can’t updated with the current state of the shade (open or closed) is that checkbox locate in headerRenderer. If open/close the WindowShade, headerRenderer is not changed, so the data of headerRenderer is not changed.

The property selected of checkbox isn’t changed because the render isn’t updated. So, I update the headerRenderer.

protected function shade_creationCompleteHandler(event:FlexEvent):void
{
shade.headerRenderer=new ClassFactory(itemh);
//headerRenderer=”itemh”

}

protected function shade_openedChangedHandler(event:WindowShadeEvent):void
{
shade.headerRenderer=new ClassFactory(itemh);
}
At last,I want to ask why header is only in render,but a component member of windowshade
Thanks

@xiahui: Something must get updated with the current state of the shade (open or closed). I suggest using the debugger. Wire up the event listeners and set a breakpoint inside openHandler(). Alternately, you can keep track of the state manually, just say isOpen = true in the openHandler() and isOpen = false in the closeHandler().

I maybe describe my question.
I only want to change checkbox’s icon when opening/closing the shade, but WindowShade(parent).opened doesn’t get updated – it just keeps the initial value. how can i do?

i meet the same quesion with Opher in flex4, i also want to use
shade.addEventListener(WindowShadeEvent.OPEN_BEGIN, openHandler);
but how to write openHandler() function?

@Opher: You could try to listen for the open/close events directly on the shade like this:

shade.addEventListener(WindowShadeEvent.OPEN_BEGIN, openHandler);
shade.addEventListener(WindowShadeEvent.CLOSE_END, closeHandler);

Then you can do whatever you need to do in the event handlers.

Hi,

I’ve been trying to use this technique, but it seems like “WindowShade(parent).opened” doesn’t get updated when opening/closing the shade – it just keeps the initial value, so the checkbox doesn’t change its state. . Any idea what I’m doing wrong?

Thanks! That works for me!

@Abhishek: If you want a border outside the windowshade, I’d be tempted to just put the shade into a container with a border. Simple is best.
