RE: [flexcomponents] initialization and binding to setters

[Alex Harui]

The width of the component is 0 until the component is given size by its parent during layout (which is when updateDisplayList gets called).  After that it is good to go.  If your issue is about binding to maxAvailGutter and not seeing it updated, the trick is to create a binding event for it so the system knows what to listen for.   [Bindable(event=”updateComplete”)] public function get maxAvailableGutter():Number {             Return Math.min(unscaledWidth,unscaledHeight)/2 – 1; }   The binding system then looks for the updateComplete event which is sent after updateDisplayList is done.   From: flexcomponents@yahoogroups.com [mailto:flexcomponents@yahoogroups.com] On Behalf Of Clare Todd Sent: Friday, September 22, 2006 10:56 AM To: flexcomponents@yahoogroups.com Subject: [flexcomponents] initialization and binding to setters   I'm making an image cropping component, and it's 98% of the way done.  I'm running into an issue and need a technique / strateg-ery advice, please:   The component allows the user to drag an Image around under a crop "window" (width and height adjustable).  The cropped result can be gotten as an Image or BitmapData to be sent to the server, shown on the screen, or, well, whatever the developer wants to do with the data.  One property of the component is "gutter".  It's a 1 pixel -- ? pixel thick border all around the edges that the image does not show through.  It allows the sides of the crop window to be pulled all the way to the edge of the image and still be visible (the gutter is forced to be at LEAST 1 pixel).  I hope that manes sense.   I want the component to have a 'get' property called "maxAvailableGutter" that, duh, tells you what the maximum gutter value can be (it's the unscaledwidth (or unscaledheight, whatever's smaller) of the component / 2 - 1 pixel) so that if you max out the gutter, the image still shows through at least 1 pixel and you can grab it and drag it.  If a developer wanted to have a NumericStepper to set the width of the gutter, the could bind the Maximum property of the Stepper to MaxAvailableGutter.  Make sense?  Probably not, but...   So...  Everyithng works fine, except when the component initializes itself.  It seems like "unscaledWidth" is not yet defined?    I'm wondering how to have values available as get where their calculation depends on the width and height?  Should I not be using "unscaled" outside of updateDisplayList ('cause I am -- get maxAvailableGutter is its own function).   Thanks!   I'll upload some code if needed, just not near my development box right now.   -- TC   PS - I'm really psyched this group exists  __._,_.___ SPONSORED LINKS Software development tool Application development software Development software Development outsourcing software Embedded software development Your email settings: Individual Email|Traditional Change settings via the Web (Yahoo!
