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.
If you want to make a TextArea scrollable, for example, when it covers an entire application page, attach it to a Flickable and combine with a ScrollBar or ScrollIndicator.
Flickable { id: flickable anchors.fill: parent TextArea.flickable: TextArea { text: "TextArea\n...\n...\n...\n...\n...\n...\n" wrapMode: TextArea.Wrap } ScrollBar.vertical: ScrollBar { } }
A TextArea that is attached to a Flickable does the following:
- Sets the content size automatically
- Ensures that the background decoration stays in place
- Clips the content

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.
See also Customizing TextArea.
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.

Signal Documentation
void pressAndHold(MouseEvent mouse) |
This signal is emitted when there is a long press (the delay depends on the platform plugin). The mouse parameter provides information about the press, including the x and y position of the press, and which button is pressed.
