Object Layering

Each object that you draw exists in a different layer on the page. The layering of an object affects it in two primary ways. First, the layering order that you specify controls that order in which the objects are created at runtime. Second, an item that is further forward in the layering appears in front of objects that are further back in the layering.

Important: This visual layering is in effect at runtime except that Graphic objects, Text objects, and Hotspots can never appear on top of any other kind of object. Example: A Graphic object cannot appear on top of a Radio Button at runtime.

By default, the Object List on the left side of the Page Layout Editor names the objects on the current page in the current layering order. If you are currently viewing the Object List according to another factor (such as alphabetically by object name), simply click on the Order column button at the top of the Object List.

Hint: To show the reverse order, click on the Order button again. The objects are now listed from highest to lowest.

There are two ways to display the object list:

  • Use the scroll bar at the bottom of the object list window to view the object list.

    Or

  • Use the splitter bar that separates the object list from the work area. If you click and hold the cursor on this bar, you will be able to drag it to the left or right.

    Initially, the object layering order is determined by the order in which you draw the objects in the editor. However, Jamba provides several toolbar buttons (and commands) to let you re-order the objects if necessary.

    Note: The Page object is always on the bottom layer.

    To change the layering order of an object:

    1. Select the object by clicking on it in the layout area or in the Object List.

    2. Click on an object reordering button in the Page Layout toolbar or choose a reordering command from the Layout menu.

    For information on the Layout menu, see Chapter 5.

    The following buttons are available in the Page Layout toolbar.
