|
41 * Icon handling in the WML Browser's Favourites Views listboxes. |
|
42 * The problem with listbox icons is that iconarray is held by the listbox's |
|
43 * itemdrawer, while their indexes are used in the model; and there is no safe |
|
44 * way to enforce that the indexes used are really exist. So this class was |
|
45 * introduced to make it safe: an instance is given to the listbox upon |
|
46 * creation; the listbox uses the factory to create the iconarray for the |
|
47 * itemdrawer, and setting icon indexes for items. This way, creating the |
|
48 * iconarray and indexing to it is in the same class. |
|
49 * Pure virtual. |
