## Detailed Description

TextField is a single line text editor. TextField extends TextInput with a placeholder text functionality, and adds decoration.

| A text field in its normal state.
| A text field that has active focus.
| A text field that is disabled.

     TextField {
         placeholderText: qsTr("Enter name")
     }

## Property Documentation

background : Item

This property holds the background item.

Note: If the background item has no explicit size specified, it automatically follows the control's size. In most cases, there is no need to specify width or height for a background item.

Note: Most controls use the implicit size of the background item to calculate the implicit size of the control itself. If you replace the background item with a custom one, you should also consider providing a sensible implicit size for it (unless it is an item like Image which has its own implicit size).

See also Customizing TextField.

bottomInset : real

This property holds the bottom inset for the background.

This property was introduced in QtQuick.Controls 2.5 (Qt 5.12).

See also Control Layout and topInset.

focusReason : enumeration

This property holds the reason of the last focus change.

Note: This property does not indicate whether the control has active focus, but the reason why the control either gained or lost focus.

Constant | Description
--- | ---
`Qt.MouseFocusReason` | A mouse action occurred.
`Qt.TabFocusReason` | The Tab key was pressed.
`Qt.BacktabFocusReason` | A Backtab occurred. The input for this may include the Shift or Control keys; e.g. Shift+Tab.
`Qt.ActiveWindowFocusReason` | The window system made this window either active or inactive.
`Qt.PopupFocusReason` | The application opened/closed a pop-up that grabbed/released the keyboard focus.
`Qt.ShortcutFocusReason` | The user typed a label's buddy shortcut
`Qt.MenuBarFocusReason` | The menu bar took focus.
`Qt.OtherFocusReason` | Another reason, usually application-specific.

## Signal Documentation

pressAndHold(MouseEvent event)

This signal is emitted when there is a long press (the delay depends on the platform plugin). The event parameter provides information about the press, including the x and y coordinates of the press, and which button is pressed.

Note: The corresponding handler is `onPressAndHold`.

See also pressed and released.

pressed(MouseEvent event)

This signal is emitted when the text field is pressed by the user. The event parameter provides information about the press, including the x and y coordinates of the press, and which button is pressed.

Note: The corresponding handler is `onPressed`.

This signal was introduced in QtQuick.Controls 2.1 (Qt 5.8).

See also released and pressAndHold.

released(MouseEvent event)

This signal is emitted when the text field is released by the user. The event parameter provides information about the release, including the x and y coordinates of the press, and which button is pressed.

Note: The corresponding handler is `onReleased`.

This signal was introduced in QtQuick.Controls 2.1 (Qt 5.8).
