RE: [flexcoders] Finding the x/y position of an object

[Shannon Hicks]

I was not in my topmost application file.... I was inside a custom component file, that was being called by another custom component, which was called by the topmost application file.   So, in theory, "this" should have referred to the proper code. In fact, the same code (minus the changes for Point vs Object) in 1.5 produces the expected result.   Shan From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Gordon Smith Sent: Tuesday, August 08, 2006 3:27 PM To: flexcoders@yahoogroups.com Subject: RE: [flexcoders] Finding the x/y position of an object >Well, for some reason when I specify "this" it always referred to the application, not the object I was trying to get the x/y of Understanding what 'this' refers to is very important when writing Flex code. All the 'this' references in a particular MXML document -- whether inside a <mx:Script> block or in event handler attributes on tags -- refer to the same "document object", the one represented by the topmost tag in the MXML file. If you are in MyApplication.mxml, 'this' is always a reference to the instance of MyApplication. If you are in MyComponent, 'this' is always a reference to the instance of MyComponent. - Gordon From: [EMAIL PROTECTED]ups.com [mailto:flexcoders@yahoogroups.com] On Behalf Of Shannon Hicks Sent: Tuesday, August 08, 2006 1:17 PM To: [EMAIL PROTECTED]ups.com Subject: RE: [flexcoders] Finding the x/y position of an object Well, for some reason when I specify "this" it always referred to the application, not the object I was trying to get the x/y of. Here's the fixed code:         private function doThis(event:Event): void {            var pt:Point = new Point(0,0);            pt = event.target.contentToGlobal(pt);         } Shan From: [EMAIL PROTECTED]ups.com [mailto:flexcoders@yahoogroups.com] On Behalf Of Gordon Smith Sent: Tuesday, August 08, 2006 3:10 PM To: [EMAIL PROTECTED]ups.com Subject: RE: [flexcoders] Finding the x/y position of an object Are your code snippets in the app file, where 'this' is a reference to the application? Or did you make an MXML component based on HBox and the code snippets are from it so that 'this' is the nested object? In neither case does it look like the right logic to me. In an application script, I think you want to do     var pt:Point = new Point(0, 0); // position of nestedObject in its own coordinates (i.e., nestedObject's coordinates)     pt = nestedObject.localToGlobal(pt) // position of nestedObject in global coordinates or (more complicated and not recommended)     var pt:Point = new Point(nestedObject.x, nestedObject.y); // position of nestedObject in its parent's coordinates (i.e., nestedObject.parent's coordinates)     pt = nestedObject.parent.localToGlobal(pt) // position of nestedObject in global coordinates Note that localToGlobal() returns a new Point; it doesn't change the Point passed in. - Gordon From: [EMAIL PROTECTED]ups.com [mailto:flexcoders@yahoogroups.com] On Behalf Of Shannon Hicks Sent: Tuesday, August 08, 2006 9:18 AM To: [EMAIL PROTECTED]ups.com Subject: [flexcoders] Finding the x/y position of an object I have a nested object (an HBox) in my app, and I'm trying to figure out the global x/y position of it. I've tried this:            var pt:Point = new Point(this.x,this.y);            this.localToGlobal(pt); But it always returns 0/0. Even if I do this:            var pt:Point = new Point(parent.x,parent.y);            this.localToGlobal(pt); It's returning an odd value, like 0/90.... the actual x/y position of the object is somewhere around 350/275 Any ideas?
