Review Your Theme Project

You can review the effects of setting parameters for your theme project in the To-Be Theme Panel and in a supported device UI display.

Review Your Theme in Theme Editor

The To-Be Theme will reflect your parameter changes as you set them and afterward. The selected theme group/subgroup can have up to three related UI screens displayed below the large screen. Theme Editor supports viewing UI screens that can be reoriented by the user, for example, calculator portrait and landscape views in their available orientations. These screens will be available in the To-Be Theme Panel.

To review your theme in the To-Be Theme Panel:

  1. Select the theme group and subgroup of the associated UI screen(s) to be displayed.
  2. Select the image resolution to be displayed.
    Image size and aspect ratio display are established by your local machine monitor resolution and whether or not an image file was added in the selected image resolution tab:
    • If an image file was added to the selected tab, the image is displayed without adjustment.
    • If an image file was not added to the selected tab, the image is displayed with adjustment.
  3. To control the To-Be Theme UI screen displayed in the panel:
    Initially, the key UI screen is displayed large. It and up to two auxiliary UI screens are in the small display.
    • To display a small UI screen as a large screen, click [small UI screen].
    • To view a small UI screen in its alternate orientation (when available), click [Image Rotate].
  4. To control the To-Be Theme Panel:
    • To display the entire To-Be Theme Panel as a separate window, click the [Panel title bar].
    • To resize the separate panel window, click and drag [Panel edge or corner].
    • To toggle a separate panel between full-screen and window, click the [Panel title bar].
    • To reattach the To-Be Theme Panel to the main screen, click and drag the panel over the main screen.
