|
|
* A list widget is a container whose children are displayed vertically or
|
|
* horizontally, in order, and can be selected.
|
|
* The list can accept only one or multiple items selection. Also has many
|
|
* modes of items displaying.
|
|
*
|
|
* A list is a very simple type of list widget. For more robust
|
|
* lists, @ref Genlist should probably be used.
|
|
*
|
|
* Smart callbacks one can listen to:
|
|
* - @c "activated" - The user has double-clicked or pressed
|
|
* (enter|return|spacebar) on an item. The @c event_info parameter
|
|
* is the item that was activated.
|
|
* - @c "clicked,double" - The user has double-clicked an item.
|
|
* The @c event_info parameter is the item that was double-clicked.
|
|
* - "selected" - when the user selected an item
|
|
* - "unselected" - when the user unselected an item
|
|
* - "longpressed" - an item in the list is long-pressed
|
|
* - "edge,top" - the list is scrolled until the top edge
|
|
* - "edge,bottom" - the list is scrolled until the bottom edge
|
|
* - "edge,left" - the list is scrolled until the left edge
|
|
* - "edge,right" - the list is scrolled until the right edge
|
|
* - "language,changed" - the program's language changed
|
|
*
|
|
* Available styles for it:
|
|
* - @c "default"
|
|
*
|
|
* Default content parts of the list items that you can use for are:
|
|
* @li "start" - A start position object in the list item
|
|
* @li "end" - A end position object in the list item
|
|
*
|
|
* Default text parts of the list items that you can use for are:
|
|
* @li "default" - label in the list item
|
|
*
