The Elementary library is a simple toolkit. It provides several widgets than can be used to build your application user interface. Widgets allow you to create applications without having to reinvent basic objects, such as buttons, lists, or text boxes. Widgets can also provide feedback to your application whenever a user interacts with them. In this guide you'll learn about the basics of Elementary, as well as some concepts of the Elementary configuration framework. You'll also discover some commonly used Widgets.
In this section, you'll learn how widgets are built in a hierarchical manner. You will also discover how to build a basic Elementary application and the various callbacks that can be registered for Widgets.
Elementary can be configured using profiles. This section details some configuration items that can be modified to tweak the use of Elementary.
The background widget can be used to set a solid background for a window or container object. It works like an image but has some background specific properties such as setting to tiled, centered, scaled, or stretched.
The button widget is a simple push button. It's composed of a label icon and icon object. It also has an auto-repeat feature. The Check Widget toggles a Boolean value (true or false).
The Check widget is a simple check box. It is similar to the radio widget, except that it does not work as a group. It toggles the value of a boolean between true and false.
The Colorselector widget offers the user a color palette. It has different modes, each of which support different color configuration.
The Ctxpopup widget is a contextual popup which can display a list of items.
The Datetime widget can display and input date and time values.
The Entry widget is a box into which a user can enter text.
The Flip widget can hold two Evas objects. This allows the user to 'flip' between these objects using a variety of predefined animations.
The GLView widget can render OpenGL in an Elementary object, hiding EvasGL complexity.
The Icon widget is based on the Image Widget and is used to display images in icon format.
The Image widget can load and display images from a file or virtual memory.
The Index widget provides an index for fast access to other User Interface (UI) items.
The Label widget displays text with simple Hypertext Markup Language (HTML)-like markup. List It offers a very simple ways to manage a small number of items. If you need to manage a larger amount use the Genlist Widget instead.
The List widget is a very simple type of a list widget. It is not to be used to manage a lot of items. For that, genlists are a better option. The list items can contain a text and two contents (“start”, and “end”).
The Notify widget displays a container in a specific region of the parent object. It can also receive some content and automatically hide after a certain amount of time.
The Panel widget is an animated object which can contain child objects. It can be expanded or contracted by clicking the button on its edge.
The Photo widget can be used to display a photo, such as a contact image. If no photo is set, the widget displays a person icon to show that it is a photo placeholder.
The Photocam widget is designed to display high-resolution photos taken with a digital camera. It allows you to quickly load, zoom and resize photos. The widget is optimized for JPEG images and has a low memory footprint.
The plug widget allows you to show an Evas object created by another process. It can be used anywhere like any other Elementary widget.
The Popup widget shows a pop-up area that can contain title, content and action sections.
The Progressbar widget can be used to display the progress of a given job.
The Radio widget can display multiple options but Users can only select one. The Widget is composed of an indicator (selected/unselected), an optional icon and/or label. It's usually grouped with 2 or more other radio widgets but can be used alone.
The Segmentcontrol widget consists of several segment items. A segment item is similar to a discrete two state button. Any time, only one segment item can be selected. A segment item is composed of a label (text) and an icon.
The Slider widget is a draggable bar which is used to select a value from a specified range.
The Spinner widget enables the user to increase or decrease a numeric value using arrow buttons.
The Toolbar widget is a scrollable list of items. It can also show a menu when an item is selected. Only one item can be selected at a time.
The Tooltip widget is a smart object used to show tips or information about a parent object. It appears when the mouse hovers over the parent object.
The transit widget can apply several transition effects to an Evas object, such as transformations and rotations. The use of the transit widget is documented in the Creating Animations and Effects guide.
The Win widget is the root window widget. It allows you to create and store content inside it, so is used by almost every application. Win is handled by the Window Manager.
