详细描述
Item (and all derived types) provides built in support for states and transitions via its state, states and transitions properties. StateGroup provides an easy way to use this support in other (non-Item-derived) types.
MyCustomObject { StateGroup { id: myStateGroup states: State { name: "state1" // ... } transitions: Transition { // ... } } onSomethingHappened: myStateGroup.state = "state1"; }
参见 Qt Quick States, Transitions, and Qt QML.
属性
This property holds the name of the current state of the state group.
This property is often used in scripts to change between states. For example:
function toggle() { if (button.state == 'On') button.state = 'Off'; else button.state = 'On'; }
If the state group is in its base state (i.e. no explicit state has been set), state will be a blank string. Likewise, you can return a state group to its base state by setting its current state to ''.
参见 Qt Quick States.
states : list<State> |
This property holds a list of states defined by the state group.
StateGroup { states: [ State { // State definition... }, State { // ... } // Other states... ] }
参见 Qt Quick States.
transitions : list<Transition> |
This property holds a list of transitions defined by the state group.
StateGroup { transitions: [ Transition { // ... }, Transition { // ... } // ... ] }
参见 Transitions.
