Setting \l {Item::focus}{focus} to \c true enables the TextEdit item to receive keyboard focus.
Note that the TextEdit does not implement scrolling, following the cursor, or other behaviors specific
to a look-and-feel. For example, to add flickable scrolling that follows the cursor:
\snippet qml/texteditor.qml 0
A particular look-and-feel might use smooth scrolling (eg. using SmoothedAnimation), might have a visible
scrollbar, or a scrollbar that fades in to show location, etc.
Clipboard support is provided by the cut(), copy(), and paste() functions, and the selection can
be handled in a traditional "mouse" mechanism by setting selectByMouse, or handled completely
from QML by manipulating selectionStart and selectionEnd, or using selectAll() or selectWord().
You can translate between cursor positions (characters from the start of the document) and pixel
points using positionAt() and positionToRectangle().

of the glyphs. The text layout will be typographically accurate, using the same metrics
as are used e.g. when printing.
\value Font.PreferVerticalHinting - If possible, render text with no horizontal hinting,
but align glyphs to the pixel grid in the vertical direction. The text will appear
crisper on displays where the density is too low to give an accurate rendering
of the glyphs. But since the horizontal metrics of the glyphs are unhinted, the text's
layout will be scalable to higher density devices (such as printers) without impacting
details such as line breaks.
\value Font.PreferFullHinting - If possible, render text with hinting in both horizontal and
vertical directions. The text will be altered to optimize legibility on the target
device, but since the metrics will depend on the target size of the text, the positions
of glyphs, line breaks, and other typographical detail will not scale, meaning that a
text layout may look different on devices with different pixel densities.

\qmlmethod QtQuick::TextEdit::moveCursorSelection(int position, SelectionMode mode)
Moves the cursor to \a position and updates the selection according to the optional \a mode
parameter. (To only move the cursor, set the \l cursorPosition property.)
When this method is called it additionally sets either the
selectionStart or the selectionEnd (whichever was at the previous cursor position)
to the specified position. This allows you to easily extend and contract the selected
text range.
The selection mode specifies whether the selection is updated on a per character or a per word
basis. If not specified the selection mode will default to \c {TextEdit.SelectCharacters}.
\list
\li TextEdit.SelectCharacters - Sets either the selectionStart or selectionEnd (whichever was at
the previous cursor position) to the specified position.
\li TextEdit.SelectWords - Sets the selectionStart and selectionEnd to include all
words between the specified position and the previous cursor position. Words partially in the
range are included.
\endlist
For example, take this sequence of calls:
\code
cursorPosition = 5
moveCursorSelection(9, TextEdit.SelectCharacters)
moveCursorSelection(7, TextEdit.SelectCharacters)
\endcode
This moves the cursor to position 5, extend the selection end from 5 to 9
and then retract the selection end from 9 to 7, leaving the text from position 5 to 7
selected (the 6th and 7th characters).
The same sequence with TextEdit.SelectWords will extend the selection start to a word boundary
before or on position 5 and extend the selection end to a word boundary on or past position 9.

\li Qt.ImhDate - The text editor functions as a date field.
\li Qt.ImhTime - The text editor functions as a time field.
