\qmltype TextArea
\inqmlmodule QtQuick.Controls
\since 5.1
\ingroup controls
\brief Displays multiple lines of editable formatted text.
\image textarea.png
It can display both plain and rich text. For example:
\qml
TextArea {
width: 240
text:
"Lorem ipsum dolor sit amet, consectetur adipisicing elit, " +
"sed do eiusmod tempor incididunt ut labore et dolore magna " +
"aliqua. Ut enim ad minim veniam, quis nostrud exercitation " +
"ullamco laboris nisi ut aliquip ex ea commodo cosnsequat. ";
}
\endqml
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().
You can create a custom appearance for a TextArea by
assigning a \l {TextAreaStyle}.

This property holds whether the TextArea has partial text input from an input method.

to edit or commit the partial text. This property can be used to determine when to disable
events handlers that may interfere with the correct operation of an input method.

\qmlproperty enumeration TextArea::inputMethodHints
Provides hints to the input method about the expected content of the text edit, and how it

The default value is \c Qt.ImhNone.
Flags that alter behavior are:
\list
\li Qt.ImhHiddenText - Characters should be hidden, as is typically used when entering passwords.
\li Qt.ImhSensitiveData - Typed text should not be stored by the active input method
in any persistent storage like predictive user dictionary.
\li Qt.ImhNoAutoUppercase - The input method should not try to automatically switch to upper case
when a sentence ends.
\li Qt.ImhPreferNumbers - Numbers are preferred (but not required).
\li Qt.ImhPreferUppercase - Upper case letters are preferred (but not required).
\li Qt.ImhPreferLowercase - Lower case letters are preferred (but not required).
\li Qt.ImhNoPredictiveText - Do not use predictive text (i.e. dictionary lookup) while typing.
\li Qt.ImhDate - The text editor functions as a date field.
\li Qt.ImhTime - The text editor functions as a time field.
\endlist
Flags that restrict input (exclusive flags) are:
\list
\li Qt.ImhDigitsOnly - Only digits are allowed.
\li Qt.ImhFormattedNumbersOnly - Only number input is allowed. This includes decimal point and minus sign.
\li Qt.ImhUppercaseOnly - Only upper case letter input is allowed.
\li Qt.ImhLowercaseOnly - Only lower case letter input is allowed.
\li Qt.ImhDialableCharactersOnly - Only characters suitable for phone dialing are allowed.
\li Qt.ImhEmailCharactersOnly - Only characters suitable for email addresses are allowed.
\li Qt.ImhUrlCharactersOnly - Only characters suitable for URLs are allowed.
\endlist

\list

Whether the user can interact with the TextArea item.

\qmlmethod void TextArea::moveCursorSelection(int position, SelectionMode mode = TextEdit.SelectCharacters)
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 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 the 5th position, extends the selection end from 5 to 9,
and then retracts the selection end from 9 to 7, leaving the text from the 5th
position to the 7th position selected (the 6th and 7th characters).
The same sequence with TextEdit.SelectWords will extend the selection start to a word boundary
before or on the 5th position, and extend the selection end to a word boundary on or past the 9th position.
