A file selector is a widget that allows a user to navigate through a file system, reporting file selections back via its API.

It contains shortcut buttons for home directory (~) and to jump one directory upwards (..), as well as cancel/ok buttons to confirm/cancel a given selection. After either one of those two former actions, the file selector will issue its "done" smart callback.

There's a text entry on it, too, showing the name of the current selection. There's the possibility of making it editable, so it is useful on file saving dialogs on applications, where one gives a file name to save contents to, in a given directory in the system. This custom file name will be reported on the "done" smart callback (explained in sequence).

Finally, it has a view to display file system items into in two possible forms:

list
grid

If Elementary is built with support of the Ethumb thumbnailing library, the second form of view will display preview thumbnails of files which it supports.

This widget inherits from the Layout one, so that all the functions acting on it also work for file selector objects.

This widget emits the following signals, besides the ones sent from Layout:

"activated" - the user activated a file. This can happen by double-clicking or pressing Enter key. (event_info is a pointer to the activated file path)
"selected" - the user has clicked on a file (when not in folders-only mode) or directory (when in folders-only mode)
"selected,invalid" - the user has tried to access wrong path which does not exist.
"directory,open" - the list has been populated with new content (event_info is a pointer to the directory's path, a stringshared string)
"done" - the user has clicked on the "ok" or "cancel" buttons (event_info is a pointer to the selection's path, a stringshared string)
"focused" - When the fileselector has received focus. (since 1.9)
"unfocused" - When the fileselector has lost focus. (since 1.9)

For text, elm_layout_text_set() will work here on:

"ok" - OK button label if the ok button is set.
Since (EFL) :
1.8
"cancel" - Cancel button label if the cancel button is set.
Since (EFL) :
1.8

Add a new file selector widget to the given parent Elementary (container) object

Parameters:

parent The parent object

Returns:: a new file selector widget handle or NULL, on errors

This function inserts a new file selector widget on the canvas.

Examples:: fileselector_example.c.

Eina_Bool elm_fileselector_buttons_ok_cancel_get ( const Elm_Fileselector * obj )

Get whether the "ok" and "cancel" buttons on a given file selector widget are being shown.

Parameters:

[in]	obj	The object.
[in]	visible	`true` to show buttons, `false` to hide.

Examples:: fileselector_example.c.

Eina_Bool elm_fileselector_custom_filter_append	(	Evas_Object *	obj,

Parameters:

obj	The file selector object
is_save	`EINA_TRUE` to make the file selector a "saving dialog", `EINA_FALSE` otherwise. Default is `EINA_TRUE`.

Parameters:

obj	The file selector object
mode	The mode of the fileselector, being it one of #ELM_FILESELECTOR_LIST (default) or #ELM_FILESELECTOR_GRID. The first one, naturally, will display the files in a list. The latter will make the widget to display its entries in a grid form.

Note:: By using elm_fileselector_expandable_set(), the user may trigger a tree view for that list.; If Elementary is built with support of the Ethumb thumbnailing library, the second form of view will display preview thumbnails of files which it supports. You must have elm_need_ethumb() called in your Elementary for thumbnailing to work, though.

Get a list of selected paths in the file selector.

Parameters:

obj	The file selector object

Returns:: The list of selected paths, or NULL if not in multi-select mode or none are selected.

It returns a list of the selected paths. This list pointer is only valid so long as the selection doesn't change (no items are selected or unselected, or unselected implicitly by deletion). The list contains const char *. The order of the items in this list is the order which they were selected, i.e. the first item in this list is the first item that was selected, and so on.
