== Purpose ==
A list view is basically used to show some items. It offers orientation thereby and allows navigation without the need of other controls. Additionally, a list view may be used for single selection (users select one item from a list of mutually exclusive values) or multiple selection (selections in combination with the Shift key or Control key). However, because there is no common visual clue whether a list box’ mode is single or multiple and since other controls are more efficient for single selection, a list box should be used for single selection only.

== Guidelines ==
* Use a list box for multiple selections with more than five options.
* Do not have blank list items; use meta-options, e.g. (None) instead.
* Place options that represent general options (e.g. All, None) at the beginning of the list.
* Provide extended multiple selection with Shift+Click or Ctrl+Click to select groups of contiguous or non-adjacent values, respectively.
* Sort list items in a logical order. Make sure sorting fits translation.

QListView / QListWidget
This can be single selection or multiple item selection
This can be checkable or based on selected items.
This can also be in a tree with a QTreeView
These can be more fancy (i.e Dolphin)
KComboBox is exactly the same but with optional auto-completion

Todo: Add Check box feature
<span style="color:blue">TP:</span>
* Use the check box list if it is easy for users to know which items are checked at any given time, for one or more of these reasons:
** There are no more than twice the number of options then are visible at a time
** The options are well-known (for example months of a year or days of a week)
** Usually the selected options are close to each other in the list
* In any other case, use the dual-list pattern because it allows users to easily see which items are selected at any point, without having to scroll through the available options
