\class HbAbstractEdit
\brief HbAbstractEdit is a base class for all text editors.
@proto
@hbwidgets
This is not mentioned as a class to be used directly. All editors inherit this and
basic functionality is in this class.
It uses \ref QTextDocument internally to handle the content. And in some editors the document is also exposed to direct access and manipulation.
\section functionality Functionality this class provides
\li Editor content: The editor is set read-only with method \ref setReadOnly. Content changes emit a \ref contentsChanged signal.
\li Cursor position and visibility: Cursor position can be set with slot \ref setCursorPosition and
read with method \ref cursorPosition(). It is also a property. Cursor position changes emit a \ref cursorPositionChanged signal.
Cursor visibility can be controlled with \ref setCursorVisibility.
\li Editing: There is a group of useful methods for editing the content. Clipboard functionality can be found
in \ref cut, \ref copy and \paste. Finishing editing emits a \ref editingFinished signal and text changes
emit a \ref textChanged signal.
\li Selection handling: Whenever there is a interactive selection special handles are shown which can be used to manipulate the selection.
Selection changes emit a \ref selectionChanged signal.
\li Anchor support: Anchors are strings associated to some a content in editor. There are two \ref anchorAt methods to access the anchors.
When user invokes an anchor it will open a context menu that may contain operations related to the anchor item (e.g. creating calls
for phone numbers, opening a web browser for web-addresses, etc.). This is always application specific functionality.
Editor itself does not create any anchors by examining the content.
There is also protected API in HbAbstractEdit. Some of these API methods can be exposed as public in more specific editor widgets.
\li Editor content: Both rich text and plain text are supported in HbAbstractEdit. Depending on the actual
editor widget only one or the other type might be supported. Plain text content is set with
method \ref setPlainText. Method \ref toPlainText returns the content converted to plain text.
\li Focus control: Editor is responsble for controlling the input panel visibility. In some situations special editor may need to also handle this, but in general it is always handled by HbAbstractEdit.
Input panel is closed when editor loses focus.
\li Cursor control: A convenience method \ref moveCursor can also be used to move the cursor.
\li Scrolling: When e.g. the size of the content exceeds the size of editor, method \ref setScrollable
can be used to make the editor scrollable. Method isScrollable tells whether the editor is scrollable or not.
Method scrollArea returns the used scroll area widget. Scrolling is enabled by default.
\li Input validation: The validator for restricting the content input is set with method \ref setValidator. Only \ref HbValidator
based validators can be used.
\section composition Widget composition
Editor widget consists of these sub-items visible in the picture.
In this example editor shows only one visible line of the content.
\image html editor_composition.jpg
The size of the canvas is always same as the size of the document, and the width of the scroll area
is same as the width of the document. The editor margins are defined in the CSS.
