/**
|
|
* @defgroup Gengrid Gengrid
|
|
*
|
|
* This widget aims to position objects in a grid layout while
|
|
* actually building only the visible ones, using the same idea as
|
|
* genlist: the user define a class for each item, specifying
|
|
* functions that will be called at object creation and deletion.
|
|
*
|
|
* A item in the Gengrid can have 0 or more text labels (they can be
|
|
* regular text or textblock - that's up to the style to determine), 0
|
|
* or more icons (which are simply objects swallowed into the Gengrid
|
|
* item) and 0 or more boolean states that can be used for check,
|
|
* radio or other indicators by the edje theme style. A item may be
|
|
* one of several styles (Elementary provides 1 by default -
|
|
* "default", but this can be extended by system or application custom
|
|
* themes/overlays/extensions).
|
|
*
|
|
* In order to implement the ability to add and delete items on the
|
|
* fly, Gengrid implements a class/callback system where the
|
|
* application provides a structure with information about that type
|
|
* of item (Gengrid may contain multiple different items with
|
|
* different classes, states and styles). Gengrid will call the
|
|
* functions in this struct (methods) when an item is "realized" (that
|
|
* is created dynamically while scrolling). All objects will simply be
|
|
* deleted when no longer needed with evas_object_del(). The
|
|
* Elm_GenGrid_Item_Class structure contains the following members:
|
|
*
|
|
* item_style - This is a constant string and simply defines the name
|
|
* of the item style. It must be specified and the default should be
|
|
* "default".
|
|
*
|
|
* func.label_get - This function is called when an actual item object
|
|
* is created. The data parameter is the one passed to
|
|
* elm_gengrid_item_append() and related item creation functions. The
|
|
* obj parameter is the Gengrid object and the part parameter is the
|
|
* string name of the text part in the edje design that is listed as
|
|
* one of the possible labels that can be set. This function must
|
|
* return a strdup'()ed string as the caller will free() it when done.
|
|
*
|
|
* func.icon_get - This function is called when an actual item object
|
|
* is created. The data parameter is the one passed to
|
|
* elm_gengrid_item_append() and related item creation functions. The
|
|
* obj parameter is the Gengrid object and the part parameter is the
|
|
* string name of the icon part in the edje design that is listed as
|
|
* one of the possible icons that can be set. This must return NULL
|
|
* for no object or a valid object. The object will be deleted by
|
|
* Gengrid on shutdown or when the item is unrealized.
|
|
*
|
|
* func.state_get - This function is called when an actual item object
|
|
* is created. The data parameter is the one passed to
|
|
* elm_gengrid_item_append() and related item creation functions. The
|
|
* obj parameter is the Gengrid object and the part parameter is the
|
|
* string name of th state part in the edje design that is listed as
|
|
* one of the possible states that can be set. Return 0 for false and
|
|
* 1 for true. Gengrid will emit a signal to the edje object with
|
|
* "elm,state,XXX,active" "elm" when true (the default is false),
|
|
* where XXX is the name of the part.
|
|
*
|
|
* func.del - This is called when elm_gengrid_item_del() is called on
|
|
* an item or elm_gengrid_clear() is called on the Gengrid. This is
|
|
* intended for use when actual Gengrid items are deleted, so any
|
|
* backing data attached to the item (e.g. its data parameter on
|
|
* creation) can be deleted.
|
|
*
|
|
* If the application wants multiple items to be able to be selected,
|
|
* elm_gengrid_multi_select_set() can enable this. If the Gengrid is
|
|
* single-selection only (the default), then
|
|
* elm_gengrid_select_item_get() will return the selected item, if
|
|
* any, or NULL if none is selected. If the Gengrid is multi-select
|
|
* then elm_gengrid_selected_items_get() will return a list (that is
|
|
* only valid as long as no items are modified (added, deleted,
|
|
* selected or unselected).
|
|
*
|
|
* If an item changes (state of boolean changes, label or icons
|
|
* change), then use elm_gengrid_item_update() to have Gengrid update
|
|
* the item with the new state. Gengrid will re-realize the item thus
|
|
* call the functions in the _Elm_Gengrid_Item_Class for that item.
|
|
*
|
|
* To programmatically (un)select an item use
|
|
* elm_gengrid_item_selected_set(). To get its selected state use
|
|
* elm_gengrid_item_selected_get(). To make an item disabled (unable to
|
|
* be selected and appear differently) use
|
|
* elm_gengrid_item_disabled_set() to set this and
|
|
* elm_gengrid_item_disabled_get() to get the disabled state.
|
|
*
|
|
* Cells will only call their selection func and callback when first
|
|
* becoming selected. Any further clicks will do nothing, unless you
|
|
* enable always select with
|
|
* elm_gengrid_always_select_mode_set(). This means event if selected,
|
|
* every click will make the selected callbacks be called.
|
|
* elm_gengrid_no_select_mode_set() will turn off the ability to
|
|
* select items entirely and they will neither appear selected nor
|
|
* call selected callback function.
|
|
*
|
|
* Remember that you can create new styles and add your own theme
|
|
* augmentation per application with elm_theme_extension_add(). If you
|
|
* absolutely must have a specific style that overrides any theme the
|
|
* user or system sets up you can use elm_theme_overlay_add() to add
|
|
* such a file.
|
|
*
|
|
* Signals that you can add callbacks for are:
|
|
*
|
|
* "clicked,double" - The user has double-clicked or pressed enter on
|
|
* an item. The event_infoparameter is the Gengrid item
|
|
* that was double-clicked.
|
|
* "selected" - The user has made an item selected. The event_info
|
|
* parameter is the Gengrid item that was selected.
|
|
* "unselected" - The user has made an item unselected. The event_info
|
|
* parameter is the Gengrid item that was unselected.
|
|
* "realized" - This is called when the item in the Gengrid is created
|
|
* as a real evas object. event_info is the Gengrid item that was
|
|
* created. The object may be deleted at any time, so it is up to
|
|
* the caller to not use the object pointer from
|
|
* elm_gengrid_item_object_get() in a way where it may point to
|
|
* freed objects.
|
|
* "unrealized" - This is called when the real evas object for this item
|
|
* is deleted. event_info is the Gengrid item that was created.
|
|
* "changed" - Called when an item is added, removed, resized or moved
|
|
* and when gengrid is resized or horizontal property changes.
|
|
* "drag,start,up" - Called when the item in the Gengrid has been
|
|
* dragged (not scrolled) up.
|
|
* "drag,start,down" - Called when the item in the Gengrid has been
|
|
* dragged (not scrolled) down.
|
|
* "drag,start,left" - Called when the item in the Gengrid has been
|
|
* dragged (not scrolled) left.
|
|
* "drag,start,right" - Called when the item in the Gengrid has been
|
|
* dragged (not scrolled) right.
|
|
* "drag,stop" - Called when the item in the Gengrid has stopped being
|
|
* dragged.
|
|
* "drag" - Called when the item in the Gengrid is being dragged.
|
|
* "scroll" - called when the content has been scrolled (moved).
|
|
* "scroll,drag,start" - called when dragging the content has started.
|
|
* "scroll,drag,stop" - called when dragging the content has stopped.
|
|
*
|
|
* --
|
|
* TODO:
|
|
* Handle non-homogeneous objects too.
