Popups were really valuble in Flex 1.5. Most didn't know about the depth & scoping capabilites in Flash Player, nor needed to care. Popups worked great for putting stuff "above everything" and making it modal.
Nowadays, with states and the DisplayList, the only valid reason I can see is modality. Thus, I'd avoid 'em like the plague unless you can answer yes to the following question: "Does the form need to be modal?". ----- Original Message ----- From: "Stefan Schmalhaus" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Thursday, July 27, 2006 5:37 AM Subject: [flexcoders] Cairngorm: Managing Popup Windows I've done some research on this list but haven't found any valid information on what's considered best pratice in dealing with popup windows. The few Cairngorm sample apps that are around don't seem to use the TitleWindow component at all. Let's say I have a simple DataGrid populated with some user data. If I click on a row in the DataGrid a popup window opens with a form for editing the user information. The popup window also has two buttons for deleting or saving (updating) the user account. I have done stuff like this several times in Flash/AS2 but I've never used a framework approach so far. Now, if I look at this rather simple task from a Cairngorm perspective it doesn't seem to be that simple any more. (But I guess that's because I'm not yet too familiar with Cairngorm.) I know how to establish databinding between the data provider and {model.users} and all this basic Cairngorm stuff. But what happens when a row is clicked? I'm not even sure if I'm supposed to treat this event as a single event ("selectUser" or "openPopup"?) or as a chain of two events ("selectUser" -> "openPopup"). Since my user information is organized as an array of value objects it's easy to assign the selected user VO to model.selectedUser: model.selectedUser = UserVO(userList.selectedItem); But am I "allowed" to directly access the ModelLocator from my view component? Or am I supposed to route this simple action through the Cairngorm "command chain" (Cairngorm Event -> Front Controller -> Command Class -> ModelLocator)? Next question, what about the popup itself? Can I simply use PopUpManager.createPopUp( this, UserFormView , true)? Or am I supposed to treat this as a Cairngorm Event, too? I feel in "safe Cairngorm terrain" again with the "updateUser" and "deleteUser" actions on the buttons. But what about closing the popup window? Is this even worth a Cairngorm event? I guess these questions sound rather stupid to those of you who are more experienced with frameworks. But at the moment these questions are obstacles on my way to master Cairngorm (which I will hopefully do one day). I apologize for my verbose post and my bad English, but I hope that someone can shed some light on these issues.
