Property Documentation
action : Action |
The Action associated with this ActionItem. If action is set, the values of the Action properties are copied to the values of the ActionItem properties.
The property specifies whether the StyledItem can gain focus on a mouse press/touch or not. When the value is true, the focus will be set on the component when the mouse is pressed over it or touched. However if one of the component's ancestor StyledItem or derived is having the property value false, the focus will not be gained automatically.
In the following example the TextField will stay focused when clicked on the red rectangle.
import QtQuick 2.4 import Ubuntu.Components 1.2 Column { width: units.gu(50) height: units.gu(100) StyledItem { objectName: "passiveScope" width: parent.width height: units.gu(30) Rectangle { anchors.fill: parent color: "red" StyledItem { objectName: "activeScope" activeFocusOnPress: true anchors.fill: parent } } } TextField { id: input text: "The input stays focus even if red box is clicked" } Component.onCompleted: input.forceActiveFocus() Connections { target: window onActiveFocusItemChanged: console.debug("focus on", window.activeFocusItem) } }
The default value is false
