\ingroup controls
\brief Displays a single line of editable plain text.
\image textfield.png
TextField is used to accept a line of text input. Input constraints can be
placed on a TextField item (for example, through a \l validator or \l
inputMask). Setting \l echoMode to an appropriate value enables
TextField to be used for a password input field.
\qml
TextField {
placeholderText: qsTr("Enter name")
}
\endqml
You can create a custom appearance for a TextField by
assigning a \l {TextFieldStyle}.
\sa TextArea, TextInput
*/
Control {

/*!
\qmlproperty bool TextField::acceptableInput
Returns \c true if the text field contains acceptable
text.
If a validator or input mask was set, this property will return \c
true if the current text satisfies the validator or mask as
a final string (not as an intermediate string).
The default value is \c true.

The rectangle where the text cursor is rendered within the text field.

\qmlproperty string TextField::displayText
This property holds the text displayed in the TextField.
If \l echoMode is set to TextInput::Normal, this holds the

this property holds the text visible to the user, while
the \l text property holds the actual entered text.
*/
readonly property alias displayText: textInput.displayText
/*!
\qmlproperty enumeration TextField::echoMode
Specifies how the text should be displayed in the
TextField.
The possible modes are:
\list
\li TextInput.Normal - Displays the text as it is. (Default)
\li TextInput.Password - Displays asterisks instead of characters.
\li TextInput.NoEcho - Displays nothing.
\li TextInput.PasswordEchoOnEdit - Displays characters as they are
entered while editing, otherwise displays asterisks.

\qmlproperty font TextField::font
Sets the font of the TextField.

/*!
\qmlproperty enumeration TextField::horizontalAlignment
Sets the alignment of the text within the TextField item's width.
By default, the horizontal text alignment follows the natural alignment
of the text, for example text that is read from left to right will be
aligned to the left.
The possible alignment values are:
\list
\li TextInput.AlignLeft
\li TextInput.AlignRight
\li TextInput.AlignHCenter
\endlist
When using the attached property, LayoutMirroring::enabled, to mirror
application layouts, the horizontal alignment of text will also be

unchanged. To query the effective horizontal alignment of TextField, use
the read-only property \c effectiveHorizontalAlignment.

item's width.

/*!
\qmlproperty enumeration TextField::verticalAlignment
Sets the alignment of the text within the TextField item's height.

\li TextInput.AlignTop
\li TextInput.AlignBottom
\li TextInput.AlignVCenter (default).
\endlist

Sets an input mask on the TextField, restricting the allowable text
inputs. See QLineEdit::inputMask for further details, as the exact same
mask strings are used by TextField.
\sa acceptableInput, validator
*/
property alias inputMask: textInput.inputMask
/*!
\qmlproperty bool TextField::inputMethodComposing
\since QtQuick.Controls 1.3
This property holds whether the TextField has partial text input from an input method.
While it is composing an input method may rely on mouse or key events from the TextField
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.
*/
readonly property bool inputMethodComposing: !!textInput.inputMethodComposing
/*!
\qmlproperty enumeration TextField::inputMethodHints
Provides hints to the input method about the expected content of the
text field and how it should operate.
The value is a bit-wise combination of flags, or \c Qt.ImhNone if no
hints are set.
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.
This is automatically set when setting echoMode to \c TextInput.Password.
\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 - Uppercase letters are preferred (but not required).
\li Qt.ImhPreferLowercase - Lowercase letters are preferred (but not required).
\li Qt.ImhNoPredictiveText - Do not use predictive text (for example, 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.
\li Qt.ImhMultiLine - The text editor doesn't close software input keyboard when Return or Enter key is pressed (since QtQuick.Controls 1.3).
\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 uppercase letter input is allowed.
\li Qt.ImhLowercaseOnly - Only lowercase 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
Masks:
\list
\li Qt.ImhExclusiveInputMask - This mask yields nonzero if any of the exclusive flags are used.
\endlist
*/
property alias inputMethodHints: textInput.inputMethodHints
/*!
\qmlproperty int TextField::length
Returns the total number of characters in the TextField item.
If the TextField has an input mask, the length will include mask
characters and may differ from the length of the string returned by the
\l text property.
This property can be faster than querying the length of the \l text
property as it doesn't require any copying or conversion of the
TextField's internal string data.

This property holds the maximum permitted length of the text in the
TextField.
If the text is too long, it is truncated at the limit.

\qmlproperty string TextField::placeholderText
This property contains the text that is shown in the text field when the
text field is empty.
*/

/*!
\qmlproperty bool TextField::readOnly
Sets whether user input can modify the contents of the TextField. Read-
only is different from a disabled text field in that the text field will
appear to be active and text can still be selected and copied.
If readOnly is set to \c true, then user input will not affect the text.
Any bindings or attempts to set the text property will still
work, however.

Provides the text currently selected in the text input.

to use.

*/
readonly property alias selectionEnd: textInput.selectionEnd

\qmlproperty int TextField::selectionStart
The cursor position before the first character in the current selection.

selectAll(), or selectWord().

/*!
\qmlproperty string TextField::text
This property contains the text in the TextField.

\qmlproperty Validator TextField::validator
Allows you to set a validator on the TextField. When a validator is set,
the TextField will only accept input which leaves the text property in
an intermediate state. The accepted signal will only be sent
if the text is in an acceptable state when enter is pressed.
Currently supported validators are \l[QtQuick]{IntValidator},
\l[QtQuick]{DoubleValidator}, and \l[QtQuick]{RegExpValidator}. An
example of using validators is shown below, which allows input of
integers between 11 and 31 into the text input:
\code
import QtQuick 2.2
import QtQuick.Controls 1.2
TextField {
validator: IntValidator {bottom: 11; top: 31;}
focus: true
}
\endcode
\sa acceptableInput, inputMask, accepted

This property contains the edit \l Menu for working
with text selection. Set it to \c null if no menu
is wanted.
*/

/*!
\qmlsignal TextField::accepted()
This signal is emitted when the Return or Enter key is pressed.
Note that if there is a \l validator or \l inputMask set on the text
field, the signal will only be emitted if the input is in an acceptable
state.
The corresponding handler is \c onAccepted.
*/
signal accepted()
/*!
\qmlsignal TextField::editingFinished()
\since QtQuick.Controls 1.1
This signal is emitted when the Return or Enter key is pressed or
the text field loses focus. Note that if there is a validator or
inputMask set on the text field and enter/return is pressed, this
signal will only be emitted if the input follows
the inputMask and the validator returns an acceptable state.
The corresponding handler is \c onEditingFinished.
*/

\qmlmethod void TextField::copy()
Copies the currently selected text to the system clipboard.
