## Detailed Description

TextArea is a multi-line text editor. TextArea extends TextEdit with a placeholder text functionality, and adds decoration.

     TextArea {
         placeholderText: qsTr("Enter description")
     }

TextArea is not scrollable by itself. Especially on screen-size constrained platforms, it is often preferable to make entire application pages scrollable. On such a scrollable page, a non-scrollable TextArea might behave better than nested scrollable controls. Notice, however, that in such a scenario, the background decoration of the TextArea scrolls together with the rest of the scrollable content.

### Scrollable TextArea

If you want to make a TextArea scrollable, for example, when it covers an entire application page, it can be placed inside a ScrollView.

     ScrollView {
         id: view
         anchors.fill: parent

         TextArea {
             text: "TextArea\n...\n...\n...\n...\n...\n...\n"
         }
     }

A TextArea that is placed inside a ScrollView does the following:

- Sets the content size automatically
- Ensures that the background decoration stays in place
- Clips the content

### Tab Focus

By default, pressing the tab key while TextArea has active focus results in a tab character being input into the control itself. To make tab pass active focus onto another item, use the attached KeyNavigation properties:

     TextField {
         id: textField
     }

     TextArea {
         KeyNavigation.priority: KeyNavigation.BeforeItem
         KeyNavigation.tab: textField
     }

## 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).

[since QtQuick.Controls 2.5 (Qt 5.12)] 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.

`[since QtQuick.Controls 2.1 (Qt 5.8)]` pressed(MouseEvent event)

This signal is emitted when the text area 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.

`[since QtQuick.Controls 2.1 (Qt 5.8)]` released(MouseEvent event)

This signal is emitted when the text area 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).

See also pressed and pressAndHold.
