58 \class QState -
59 \inmodule QtCore -
60 -
61 \brief The QState class provides a general-purpose state for QStateMachine. -
62 -
63 \since 4.6 -
64 \ingroup statemachine -
65 -
66 QState objects can have child states, and can have transitions to other -
67 states. QState is part of \l{The State Machine Framework}. -
68 -
69 The addTransition() function adds a transition. The removeTransition() -
70 function removes a transition. The transitions() function returns the -
71 state's outgoing transitions. -
72 -
73 The assignProperty() function is used for defining property assignments that -
74 should be performed when a state is entered. -
75 -
76 Top-level states must be passed a QStateMachine object as their parent -
77 state, or added to a state machine using QStateMachine::addState(). -
78 -
79 \section1 States with Child States -
80 -
81 The childMode property determines how child states are treated. For -
82 non-parallel state groups, the setInitialState() function must be called to -
83 set the initial state. The child states are mutually exclusive states, and -
84 the state machine needs to know which child state to enter when the parent -
85 state is the target of a transition. -
86 -
87 The state emits the QState::finished() signal when a final child state -
88 (QFinalState) is entered. -
89 -
90 The setErrorState() sets the state's error state. The error state is the -
91 state that the state machine will transition to if an error is detected when -
92 attempting to enter the state (e.g. because no initial state has been set). -
93 -
94*/ -
95 -
96/*! -

98 -
99 \brief the initial state of this state (one of its child states) -

108/*! -

110 -
111 \brief the child mode of this state -
112 -
113 The default value of this property is QState::ExclusiveStates. -
114*/ -
115 -
116/*! -
117 \enum QState::ChildMode -
118 -
119 This enum specifies how a state's child states are treated. -
120 -
121 \value ExclusiveStates The child states are mutually exclusive and an -
122 initial state must be set by calling QState::setInitialState(). -
123 -
124 \value ParallelStates The child states are parallel. When the parent state -
125 is entered, all its child states are entered in parallel. -
126*/ -
127 -
128/*! -
129 \enum QState::RestorePolicy -
130 -
131 This enum specifies the restore policy type. The restore policy -
132 takes effect when the machine enters a state which sets one or more -
133 properties. If the restore policy is set to RestoreProperties, -
134 the state machine will save the original value of the property before the -
135 new value is set. -
136 -
137 Later, when the machine either enters a state which does not set -
138 a value for the given property, the property will automatically be restored -
139 to its initial value. -
140 -
141 Only one initial value will be saved for any given property. If a value for a property has -
142 already been saved by the state machine, it will not be overwritten until the property has been -
143 successfully restored. -
144 -
145 \value DontRestoreProperties The state machine should not save the initial values of properties -
146 and restore them later. -
147 \value RestoreProperties The state machine should save the initial values of properties -
148 and restore them later. -
