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, 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:
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
}

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).
