Quartz Composer Application

LiveEdit                    A simple RTF text editor that shows how to implement 

                        live edit using a background Quartz composition with 

                        Core Animation and the Composition Repository.

Sample Requirements             The project was created using the Xcode running under 

                        Mac OS X 10.6.x or later. 

About the sample                In the sample, the user can live edit the content in 

                        the document window. A Quartz Composer QCCompositionPickerPanel 

                        is used to provide the compositions that can generate 

                        the animation backgrounds for the document. The document 

                        window is registered to receive the notification whenever 

                        a certain composition in the picker panel is selected. 

                        Once a composition is selected, a core animation layer 

                        is set up using this composition in the document to 

                        generate the animation background.

Using the Sample                Open the project using the Xcode editor which can be 

                        found in /Developer/Applications. Build the project and run. 

                        Edit the text in the document window. Click in the 

                        composition picker to change the background.
