I think it's based on the parent that you specify when you add your window to In the first place
i.e. PopUpManager.addPopUp(myWindow, myParent); PopUpManager.centerPopUp(myWindow); If you specify: Var myParent:DisplayObject = Application.application as DisplayObject; When you center the window, it should center in relation to the parent. If you were to specify: Var myParent:DisplayObject = myOtherWindow; It should center in relation to "myOtherWindow". http://livedocs.adobe.com/flex/2/langref/mx/managers/PopUpManager.html Jay Proulx [EMAIL PROTECTED] ________________________________ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of nextadvantage Sent: March 16, 2007 11:11 PM To: [email protected] Subject: [flexcoders] Center PopUp on Window not Application Anyone have some code to center a title window on window size vs application center... thx Aaron
