My experience has been with creating containers from DisplayObjects
Ok, how do you use your DisplayObjects in mxml containers (IE mxml)? You haven't implemented IFlexDisplayObject. I'm completely lost on your second paragraph.
It doesn't make sense why you wouldn't just add the container to the Panel
and then after that point add items to the container. I suggested this in my first response to this question. My sugesstion was, create the composite container BEFORE super.createChildren(), override createComponentsFromDescriptors(), remove the children that get created with createChild(). Then create public methods like addCompositeChild() removeCompositeChild() for adding and removing children from the composite container. If you try and override addChild(), you mess up overalys, measuring etc. PS An example would be making a TilePanel. If you are truly going after abstractness, you want the Panel to do what is meant to do without having a user add a Tile to the Panel in mxml. With the process above, you have successfully created a tile panel with the ability to add and remove tiles. Peace, Mike On 4/27/07, Paul J DeCoursey <[EMAIL PROTECTED]> wrote:

Alright I concede now that after reading what she is trying to do it will not be as simple as I described. My experience has been with creating containers from DisplayObjects of extending and hacking the Container itself. I have not done what she is trying to do, I have not tried to hack a Panel in this way. And to be frank I don't understand why. But here is my revised suggestion. Create a component that extends Display Object, add the Panel to it and the container that you want to have the children. You'll have to use the top, left, bottom and right properties on each of them to control the sizing and whatnot. Then override addChild and addChildAt to add any future components to the "contentPane" you created. This should work and will simulate what Containers already do and you don't have to worry about all the numChildren and other "tricky" stuff related to containers. Claudia, What is the purpose/goal of this? It doesn't make sense why you wouldn't just add the container to the Panel and then after that point add items to the container.
