Image-Related Fields and the Tab Order
Image-related fields technically have a place in the tab hierarchy, which follows data fields and inline fields:
1. Data fields
2. Inline fields
3. Signature fields
4. Circle fields
5. Barcode fields
6. Placeable bitmaps
Note:
This tab order hierarchy is not the same as the order of the nodes in the DataView tree.
Within each field type, the fields appear by default in the order they were added to the page. They can be reordered into a more user-friendly order. Except for circle fields, no data can actually be entered when the user tabs to one of these fields. However, users may still need to access the field to actively place the content into the field (e.g., to enter a signature via a signature tool or select a bitmap for a placeable bitmap field). If the field is filled through the program instead of through user intervention, they will probably be disabled or set to read-only in the application software.
In most cases, for fields other than circle fields, you can simply ignore their order. A given page is not likely to contain more than one barcode field, and, except in rare cases, more than one placeable bitmap. If there is more than one signature field and the user needs to access them, you may want to reorder them.
