/**
|
|
* @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.
|
|
*
|
|
* Signals that you can add callbacks for are:
|
|
*
|
|
* clicked - The user has double-clicked a item. The event_info parameter 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.
|
|
*
|
|
* 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.
|
|
*
|
|
*
|
|
* 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 a 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 a
|
|
* 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 a 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 a item use elm_gengrid_item_selected_set().
|
|
* To get its selected state use elm_gengrid_item_selected_get(). To make a
|
|
* item disabled (unable to be selected and appear differently) use
|
|
* elm_gengrid_item_disable_set() to set this and
|
|
* elm_gengrid_item_disable_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.
|
|
*
|
|
* --
|
|
* TODO:
|
|
* * Handle non-homogeneous objects too.
