+Control</h2>
+
+
+ <p>
+
+ A control is a user interface element that the user can interact with. Controls
+ are used in PC applications, in web pages and in mobile device applications. In
+ web pages controls are often known as "form controls". Common controls include
+ textfields, textareas, buttons, checkboxes, radio buttons, scrollbars, labels
+ and progress bars, among others. Not all controls are interactive, e.g. labels
+ simply display a value. Controls are contained within some kind of user
+ interface container such as a view or window.
+ </p>
+
+ <p>
+
+ In the WRTKit, controls are JavaScript objects that contain the state and
+ implement the behavior of the control. Controls take care of drawing themselves,
+ including changing their appearence as a result of various state changes.
+ </p>
+
+ </div>
+
+ <div class="section"><h2 class="sectiontitle">
+View</h2>
+
+
+ <p>
+
+ A container for user interface elements such as controls. On a mobile device
+ user interface views typically fill the entire screen and thus only one view can
+ be shown at a time. Views in a mobile device tend to lay out the elements it
+ contains in a vertical list that can be scrolled up and down if there is more
+ content in the view than what fits on the screen at a time.
+ </p>
+
+ <p>
+
+ In the WRTKit, views are responsible for laying out controls. Custom views can
+ be created to support advanced layouts but in the vast majority of cases the
+ default ListView is sufficient. WRTKit views are JavaScript objects.
+ </p>
+
+ </div>
+
+ <div class="section"><h2 class="sectiontitle">
+Event</h2>
+
+
+ <p>
+
+ An event is a notification of some occurrence in a user interface element, such
+ as a view or control. Events are typically propagated to application code as
+ messages or function calls or a combination of the two.
+ </p>
+
+ <p>
+
+ The WRTKit uses a model known as the "observer pattern" to deliver event
+ messages, which are JavaScript objects, to event listeners, which are JavaScript
+ callback functions. WRTKit events have a type name that can be used to
+ distinguish between different types of events. E.g. a button press produces an
+ "ActionPerformed" event.
+ </p>
+
+ </div>
+
+ <div class="section"><h2 class="sectiontitle">
+Focus</h2>
+
+
+ <p>
+
+ The control that is currently selected to receive input is said to be focused.
+ Controls can be focused in both the tab and pointer navigation modes. In the tab
+ mode the focus is moved between controls using the 4-way controller. In
+ the pointer mode the focus is moved between controls by moving the pointer to
+ "hover" above a control and then pressing a selection button to select that
+ control. Focused controls are displayed in a distinct way from other controls to
+ indicate that they are ready to be interacted with.
+ </p>
+
+ </div>
+
+ <div class="section"><h2 class="sectiontitle">
+Hovering</h2>
+
+
+ <p>
+
+ In pointer navigation mode, the pointer is said to be "hovering" above a control
+ if the pointer is located inside the control's area on the screen. Hovering is
+ similar to focus, but differs because hovering in itself does not select a
+ control for interaction. Rather a selection key must be pressed in order to
+ focus the control that the pointer is currently hovering over. Hover is
+ indicated by displaying a control in a distinct way from other controls.
+ </p>
+
+ </div>
+
+ <div class="section"><h2 class="sectiontitle">
+Navigation mode</h2>
+
+
+ <p>
+
+ A navigation mode refers to a method of selecting what user interface element to
+ interact with. The S60 Web Runtime supports two navigation modes: "tab" and
+ "pointer". In the tab mode, focus is moved between controls using the 4-way
+ controller. In pointer mode there is a pointer arrow on the screen that can be
+ moved freely using the 4-way controller. A control is focused by moving the
+ pointer arrow so that it hovers above a control, and then pressing a selection
+ key to select that control. In tab mode a control can be either in normal or
+ focused state, whereas in the pointer mode a control can be in normal, hover or
+ focused state.
