The Project Designer window appears. It is divided into four panes:


                                                     Viewer Pane           Components Pane












                    Palette Pane
                                                                                                        Properties
                                                                                                          Pane












                   Palette Pane: On the left, there is a palette pane from where we can select components like buttons,

                 images, and other functions required for our app.
                   Viewer Pane: To the right of the palette is the white area where we can view and arrange added

                 components.

                   Components Pane:  This pane shows a list of all the components added to the screen in a
                 hierarchical view.

                   Properties Pane: When we click on a component in the viewer, we see its properties listed here.
                 Properties of the components can be changed from here.

              Creating a Talking App

              In the Project Designer window, we will design the interface by choosing buttons, images or text boxes
              and specify the functionalities of our app.

              Adding a Button

              Drag and drop a Button from the Palette pane to the Viewer pane.
