Fetching data
Often it is necessary to be able to pick up a piece of data from an application, such as a phone number or address from the Phonebook. This is called fetching. It is a
Browsing data during a fetch operation should resemble the application’s normal use: the data should be arranged the same way so that it is easy to find. Only the available functions are different: the data can’t be edited.
The left softkey during a fetch operation is labeled Select, and it activates the same function as the Select key: it selects the data currently in focus. The right softkey is Cancel, and returns to the previous state without bringing back any data.
Sometimes it is feasible to use a multiselection list for fetching data. This should be done when it is probable that the user wants to select more than one item for fetching. An example of this is creating a group in the Phonebook to be used as a distribution list: a list of names is offered to the user, and since the probable intention is to have more than one name in the group, a multiselection list is a good tool to use. (See section Multiselection list in the UI components chapter.)
Settings
Global settings – the ones that affect several applications or general issues within the device, are collected into the General Settings application.
Sometimes a general setting may be duplicated as an
If the number of setting items (within an application) is large, it may be necessary to divide them into groups. The grouping can be done in the following ways:
Use tabs to access different setting groups
Design a hierarchical setting tree, use 'setting folders' in the top level (there may be individual settings and folders in one list; this is an exception to the rule that only setting items should exist in one list).
