  1. Tried that, did not work. Also the ASDOCs say null is the default anyway. To do it, I had to set a rectangle that is much larger than the container the TM is in or the TM itself, and set the bounds to that. [bindable] private var myrect:Rectangle = new Rectangle(-2000,-2000,4000,4000);
  2. I seem to remember a way to allow object in the TM to not be constrained by the size of the TM instance; that is, they are free to bleed off the edges. For the life of me, I can't find the property. What is it?
  3. I have an application where I ask the user dimensions of a room and then add 4 walls for them to use as a starting point (so they can tweak the room with drag and drop. protected function buildRoom(event:Event):void { // get numbers from dialog var w:Number = event.currentTarget.roomWidth; var l:Number = event.currentTarget.roomLength; var origin:Number = gridInc; trace('creating room '+w+' wide and '+l+' long.'); // get instances of wall objects from XMLListCollection var wallV1:Object = structural.getItemAt(0); var wallV2:Object = structural.getItemAt(0); var wallH1:Object = structural.getItemAt(1); var wallH2:Object = structural.getItemAt(1); // wall postions wallH1.x = gridInc; wallH1.y = gridInc; wallH2.x = gridInc; wallH2.y = wallV1.height+(gridInc-wallThickness); wallV1.x = gridInc; wallV1.y = gridInc; wallV2.x = wallH1.width+(gridInc-wallThickness); wallV2.y = gridInc; var wallH2y:Number = origin + (l * gridInc); var wallV2x:Number = origin + (w * gridInc); // first vertical wall addWall(wallV1, gridInc, gridInc, l, 'vert'); // second vertical wall addWall(wallV2, wallV2x, gridInc, l, 'vert'); // first horizontal wall addWall(wallH1, gridInc, gridInc, w, 'horiz'); // second horizontal wall addWall(wallH2, gridInc, wallH2y, w, 'horiz'); } /** add a new wall */ protected function addWall(obj:Object, posX:Number, posY:Number, len:Number, wallType:String):void { var actualLength:Number = len * gridInc; var stageItem:AddedItem = new AddedItem(); stageItem.source = "images/full/"+obj.img; stageItem.itemName = obj.name; var rn:int = Math.floor(Math.random() * 1000); stageItem.name = obj.name+"_"+rn; stageItem.addEventListener(Event.COMPLETE, selectMe); stageItem.x = posX; stageItem.y = posY; var item:TransformItem = ws.myManager.addItem(stageItem); updateItemCount(); } However, I have tried setting the width and/or height of the transform item both after it's added, such as item.height, in which case no items are added (or at least not visible) and I have tried right before it's added, as in stageItem.height, but then the bounding boxes are sized, not the artwork. What am I missing here? EDIT: BTW, the code posted works great in that the walls are posted, and the positioning is perfect. I just cannot set their size properly.
  4. OK, I see what is happening now, but not sure how to handle it. The problem is from adding items with the same name more than once is confusing things. However, I am unclear on what to do about it. This goes back to by continuing problem about how to "find" the correct items to add to the TM before applyFullXML is called. I am adding items with this: protected function addNewItem(obj:Object):void { var stageItem:AddedItem = new AddedItem(); stageItem.source = "/wsbp/images/full/"+obj.img; stageItem.itemName = obj.name; stageItem.name = obj.name ws.myManager.addItem(stageItem); updateItemCount(); } I was using stageItem.name = obj.name to give the Transform item a name i could associate with the original graphic, so when I load the XML I can fetch is and add it before applyFullXML. So of course, multiple TIs have the same name now, which is obviously not good. If I don't assign a name like I am here, the default item names are things like "AddedItem234", each unique. But how do I know what "AddedItem234" is, so I can load the correct graphic (AddedItem class)?
  5. I can't figure this out, since this had been working fine but I use TM to create a room, like this: Where the orange items have lockScale true and the gray walls do not. I have also disabled constrainScale on the TM in MXML, so you can stretch the walls to make a room. I save the whole thing with exportFullXML, and load it, but although the orange items are always correct, the wall objects are not: Why would this be?
  6. Yes, the "var item:TransformItem =" part was the key. I didn't think of that.
  7. I have an app where some items can be resized and some cannot: A room with furniture. I want items that define the room, such as the walls and windows, to be resizable but not things like appliances, which have a fixed size. I was hoping to do this with only one transform manager, since I need to save this as XML and wanted to avoid having to deal with 2 XML files (or is that the better way to go?) So my handler which adds objects (AddedItem extends Image) to the TM instance is: protected function addNewItem(obj:Object):void { var stageItem:AddedItem = new AddedItem(); stageItem.source = "/wsbp/images/full/"+obj.img; stageItem.itemName = obj.name; stageItem.name = obj.name; stageItem.addEventListener(Event.COMPLETE, selectMe); stageItem.x = 50; stageItem.y = 50; if (obj.sc =="n") { THESE ITEMS WOULD BE LOCKED } ws.myManager.addItem(stageItem); updateItemCount(); } Of course, my Class doesn't understand lockScale, so I can't just set it in the IF statement. How would you recommend managing this?
  8. Is there a way to get the bounding box of all the items in a FlexTransformManager? I am going to need to put my TM in a "zoomable" area, and was looking into a way to provide a "fit to window" button.
  9. Yes, that turned out to be the key item. That and the confusion over the FlexTransformManager being a DisplayObjectContainer. It works like a charm now! Very impressive. This project has a lot of interesting feature requests, so I might need to pick your brain some more. Thanks for your help on this.
  10. I will try that and report back. For the simplified case I emailed, I stripped out the save and reload to focus on the reparenting thing. If you take a look at my original post, you can see how I was trying to do it. The saving the xml works, I get an XML file like I posted originally. I load that in, it loads correctly. So, I loop through my XMLList of all the objects in the project, add the ones that match the XML file to the TM, and applyFullXML. I thought I had it, except as you can see although there are TransformItems with names that match the XML, only one was moved to its gray box while the other 2 did not. I will add in that part to my test project and send it along later. Thanks.
  11. Thanks. I sent you a new file with some explanation. For the benefit of others, I reiterate a bit here. That's my confusion, How do I add this item to a DisplayObject and THEN to the TM? In my example, I have a BorderContainer (id='container') with a TM (id='myManager') inside of it. So, I create a new Image instance, set up its source etc. and I can then add it to "container". But a subsequent call to add it to the TM does not work (if I only add it to the TM, it works). protected function addNewItem(img:String):void { var newImage:Image = new Image(); newImage.source = "images/full/"+img; newImage.x = 100; newImage.y = 200; newImage.name = "bird"; container.addElement(newImage); myManager.addItem(newImage); } The relationship between this parent object and the TM escapes me, sorry. Any example you can provide would be appreciated.
  12. I have emailed you the Flex file. It's as stripped down as it can be, I doubt you can run it but maybe you can see what I've been trying. This is the first part I am missing... the TM is myManager, which is a child or a BorderContainer "workspace" which is a child of a VGroup "mainContainer". When I try to add my elements, where do I add them? The first time around, I am adding to the TM, but are you saying to prepare for reload I don't? That's the second part that's confusing me... I guess I am having a hard time seeing how it "finds" them if they are no part of the TM.
  13. I tried to follow the earlier post on this, and got close, but I am confounded now. Here's what I have been doing: 1. I add the items in the first place to my TM Manager by getting something selected in a List when the add button is clicked. I set the instance's name based on an XML node of the selected item, which works fine. protected function addNewItem(obj:Object):void { var stageItem:AddedItem = new AddedItem(); stageItem.source = "/ttest/images/full/"+obj.img; stageItem.itemName = obj.name; stageItem.name = obj.name; var centerLine:Number = workspace.width/2; stageItem.x = centerLine - 100; stageItem.y = 200; myManager.addItem(stageItem); } To save the XML, I do the following: protected function saveBtn_clickHandler(event:MouseEvent):void { var saveData:XML = new XML(); saveData = myManager.exportFullXML(); var objSend:Object = new Object(); var dataString:String = saveData.toXMLString() objSend.data = dataString; objSend.filename = filename; objSend.userid = userid; sendData.send(objSend); } which saves this: and my stage looks like this: So now I load my xml, using an http service, and it loads like the data that was saved. I loop through this loaded xmllist and get all the "name" attributes. Then, I compare these names in a loop against the loop of all the items in all my lists to get the matches, which seems to work. Then I am trying to add each item back, like this: protected function addSavedItem(obj:XML):void { var stageItem:AddedItem = new AddedItem(); stageItem.source = "/ttest/images/full/"+obj.img; stageItem.itemName = obj.itemName; stageItem.name = obj.itemName; trace(" adding saved stage item name = "+stageItem.name); myManager.addItem(stageItem); myManager.applyFullXML(roomXML,myManager); updateItemCount(); } Which gives me this: As you can see, tracing each transform item's name gives me the correct name (in red here) and obviously the gray boxes are the correct size. But 2 of the 3 items are on the stage but not in the correct positions (i.e., the gray boxes).
  14. I need to add items to a transform manager with additional properties, and then later list all the itms in that transform manager, along with these properties. (Flex 4) For example, I am adding something that has an image along with an associated name and price. Originally, I was adding an image, so I created a class extending Image: protected function addNewItem(obj:Object):void { var stageItem:AddedItem = new AddedItem(); stageItem.source = "images/full/"+obj.img; stageItem.itemName = obj.name; stageItem.itemPrice = obj.price; stageItem.addEventListener(Event.COMPLETE, selectMe); var centerLine:Number = workspace.width/2; stageItem.x = centerLine - 100; stageItem.y = 200; myManager.addItem(stageItem); updateItemCount(); } Which works fine. However, I can't figure out how to list the objects on command. If I loop through the transform items, there is no such property as name: private function listItems():void { for each ( var item:TransformItem in myManager.items ) { trace('item = '+item.name); } } gives an error, no property of name. I'm guessing this is actually simple, but I'm missing something obvious. To reiterate, I am looking to get the results of listItems and build an XMLList of the properties.
