Detailed Description
This section is intended for people willing to create custom Elementary widgets or to contribute new (useful, unique) widgets upstream.
If neither is your case, this text won't be of any use for you.
Elementary widgets are built in a hierarchical fashion. The idea is to factorize as much code as possible between widgets with behavioral similarities, as long as to facilitate the creation of custom, new widgets, may the user need them.
It all starts with a base class, which aggregates behaviour every Elementary widget is supposed to have: #Elm_Widget_Smart_Class. Every Elementary widget will be of that type, be it directly or by means of inheriting from it.
#Elm_Widget_Smart_Class happens to be an Evas_Smart_Class. If you check out Evas' documentation on it, you'll see it's how one is supposed to create custom Evas objects, what Elementary widgets are.
Once one instantiates an Elementary widget, since it inherits from #Elm_Widget_Smart_Class, the system will raise a class instance of that type for you. But that happens only once: the first time you ask for an Elementary widget (of a given type). All subsequent ones will only point to the very same class instance. Since it's the class which points to the functions implementing the behavior of objects of that type, all of the live instances of Elementary widgets (of that type) will share the same blob of code loaded in memory to execute their routines.
Now go and take a look at #Elm_Widget_Smart_Class's fields. Because it inherits from Evas' base smart class, we got a field of that type as the first member, so that Evas can handle Elementary objects internally as if they were 'normal' Evas objects. Evas has the Evas-only behavior function pointers in there, so it's all it needs.
Then, comes a version field, so that whenever we got to update or change the fields on our base smart class, there'll be a runtime check of the version expected by Elementary and the one provided by any code linking with it. A mismatch will show the developer of that code he/she needs to recompile and link its code to a newer version of Elementary.
The next fields are the class functions themselves. We call them 'virtual' because, as in object-oriented languages, one is supposed here to override them on inheriting classes. On most of inheritances you'll probably want to call the parent's version of the class function too: you must analyse each case to tell.
Take a look at Elm_Widget_Smart_Data. That's private data bound to each Elementary object instance. It aggregates data needed for all widgets, since it's meant for the #Elm_Widget_Smart_Class-typed ones.
When inheriting from that base type, instance data for this new class has to have, as the first member, a field of type Elm_Widget_Smart_Data. This has to be respected recursively – if a third class is to be created inheriting from the one that is a direct 'child' of #Elm_Widget_Smart_Class, then the private data on this third class has to have, as its first field, a variable of the type of the private data of the second class (its parent), direct child of #Elm_Widget_Smart_Class.
It is from the base private data, Elm_Widget_Smart_Data, that we reach an object's class functions, by the given object instance. This is the reason of the first field of that struct: a pointer set to point to its class when the object is instantiated.
The following figure illustrates the widget inheritance schema.
Elementary Widgets Hierarchy Tree
The following figure illustrates the Elementary widget inheritance tree.
The Elementary Flip Class
Elementary, besides having the Flip widget, exposes its foundation – the Elementary Flip Class – in order to create other widgets which are a flip with some more logic on top.
The Elementary Frame Class
Elementary, besides having the Frame widget, exposes its foundation – the Elementary Frame Class – in order to create other widgets which are a frame with some more logic on top.
The Elementary Image Class
This class defines a common interface for image objects having an image as their basic graphics. This interface is so that one can tune various properties of the image, like:
- smooth scaling,
- orientation,
- aspect ratio during resizes, etc.
Image files may be set via memory buffers, image files, EET files with image data or Edje files. On the last case (which is exceptional), most of the properties cited above will not be changeable anymore.
The Elementary Scrollable Interface
This is a common interface for widgets having scrollable views. Widgets using/implementing this must use the EVAS_SMART_SUBCLASS_IFACE_NEW macro (instead of the EVAS_SMART_SUBCLASS_NEW one) when declaring its smart class, so an interface is also declared.
The scrollable interface comes built with Elementary and is exposed as #ELM_SCROLLABLE_IFACE.
The interface API is explained in details at #Elm_Scrollable_Smart_Interface.
An Elementary scrollable interface will handle an internal panning object. It has the function of clipping and moving the actual scrollable content around, by the command of the scrollable interface calls. Though it's not the common case, one might want/have to change some aspects of the internal panning object behavior. For that, we have it also exposed here – #Elm_Pan_Smart_Class. Use elm_pan_smart_class_get() to build your custom panning object, when creating a scrollable widget (again, only if you need a custom panning object) and set it with Elm_Scrollable_Smart_Interface::extern_pan_set.
The Elementary Actionslider Class
Elementary, besides having the Actionslider widget, exposes its foundation – the Elementary Actionslider Class – in order to create other widgets which are a actionslider with some more logic on top.
The Elementary Box Class
Elementary, besides having the Box widget, exposes its foundation – the Elementary Box Class – in order to create other widgets which are a box with some more logic on top.

The Elementary Clock Class
Elementary, besides having the Clock widget, exposes its foundation – the Elementary Clock Class – in order to create other widgets which are a clock with some more logic on top.
The Elementary Colorselector Class
Elementary, besides having the Colorselector widget, exposes its foundation – the Elementary Colorselector Class – in order to create other widgets which are a colorselector with some more logic on top.
The Elementary Combobox Class
Elementary, besides having the Combobox widget, exposes its foundation – the Elementary Combobox Class – in order to create other widgets which are a combobox with some more logic on top.
The Elementary Conformant Class
Elementary, besides having the Conformant widget, exposes its foundation – the Elementary Conformant Class – in order to create other widgets which are a conformant with some more logic on top.
The Elementary Container Class
This class defines a common interface for objects acting like containers, i.e. objects parenting others and displaying their childs "inside" of them somehow.
The container must define "parts" (or spots) into which child objects will be placed, inside of it. This is a way of handling more the one content object, by naming content locations properly. This is the role of the name argument of the virtual functions in the class.
The following object functions are meant to be used with all container objects and derived ones:
The Elementary Ctxpopup Class
Elementary, besides having the Ctxpopup widget, exposes its foundation – the Elementary Ctxpopup Class – in order to create other widgets which are a ctxpopup with some more logic on top.
The Elementary Dayselector Class
Elementary, besides having the Dayselector widget, exposes its foundation – the Elementary Dayselector Class – in order to create other widgets which are a dayselector with some more logic on top.
The Elementary Diskselector Class
Elementary, besides having the Diskselector widget, exposes its foundation – the Elementary Diskselector Class – in order to create other widgets which are a diskselector with some more logic on top.
The Elementary Entry Class
Elementary, besides having the Entry widget, exposes its foundation – the Elementary Entry Class – in order to create other widgets which are a entry with some more logic on top.
The Elementary Fileselector Class
Elementary, besides having the Fileselector widget, exposes its foundation – the Elementary Fileselector Class – in order to create other widgets which are a fileselector with some more logic on top.
The Elementary Fileselector Button Class
Elementary, besides having the Fileselector_Button widget, exposes its foundation – the Elementary Fileselector Button Class – in order to create other widgets which are a fileselector_button with some more logic on top.
The Elementary Fileselector Entry Class
Elementary, besides having the Fileselector_Entry widget, exposes its foundation – the Elementary Fileselector Entry Class – in order to create other widgets which are a fileselector_entry with some more logic on top.
The Elementary Flipselector Class
Elementary, besides having the Flipselector widget, exposes its foundation – the Elementary Flipselector Class – in order to create other widgets which are a flipselector with some more logic on top.
The Elementary Gengrid Class
Elementary, besides having the Gengrid widget, exposes its foundation – the Elementary Gengrid Class – in order to create other widgets which are a gengrid with some more logic on top.
The Elementary Genlist Class
Elementary, besides having the Genlist widget, exposes its foundation – the Elementary Genlist Class – in order to create other widgets which are a genlist with some more logic on top.
The Elementary Glview Class
Elementary, besides having the Glview widget, exposes its foundation – the Elementary Glview Class – in order to create other widgets which are a glview with some more logic on top.
The Elementary Grid Class
Elementary, besides having the Grid widget, exposes its foundation – the Elementary Grid Class – in order to create other widgets which are a grid with some more logic on top.
The Elementary Hover Class
Elementary, besides having the Hover widget, exposes its foundation – the Elementary Hover Class – in order to create other widgets which are a hover with some more logic on top.
The Elementary Hoversel Class
Elementary, besides having the Hoversel widget, exposes its foundation – the Elementary Hoversel Class – in order to create other widgets which are a hoversel with some more logic on top.
The Elementary Icon Class
This class defines a common interface for icon objects having an icon as their basic graphics.
The Elementary Index Class
Elementary, besides having the Index widget, exposes its foundation – the Elementary Index Class – in order to create other widgets which are a index with some more logic on top.
The Elementary Inwin Class
Elementary, besides having the Inwin widget, exposes its foundation – the Elementary Inwin Class – in order to create other widgets which are a inwin with some more logic on top.
The Elementary Layout Class
Elementary, besides having the Layout widget, exposes its foundation – the Elementary Layout Class – in order to create other widgets which are, basically, a certain layout with some more logic on top.
The idea is to make the creation of that widgets as easy as possible, factorizing code on this common base. For example, a button is a layout (that looks like push button) that happens to react on clicks and keyboard events in a special manner, calling its user back on those events. That's no surprise, then, that the Button implementation relies on #Elm_Layout_Smart_Class, if you go to check it.
The Layout class inherits from #Elm_Container_Smart_Class. Container parts, here, map directly to Edje parts from the layout's Edje group. Besides that, there's a whole infrastructure around Edje files:
- interfacing by signals,
- setting/retrieving text part values,
- dealing with table and box parts directly,
- etc.
Take a look at #Elm_Layout_Smart_Class's 'virtual' functions to understand the whole interface. Finally, layout objects will do part aliasing for you, if you set it up properly. For that, take a look at #Elm_Layout_Part_Alias_Description, where it's explained in detail.
