49 \class QState -

50 \inmodule QtCore -

51 -

52 \brief The QState class provides a general-purpose state for QStateMachine. -

53 -

54 \since 4.6 -

55 \ingroup statemachine -

56 -

57 QState objects can have child states, and can have transitions to other -

58 states. QState is part of \l{The State Machine Framework}. -

59 -

60 The addTransition() function adds a transition. The removeTransition() -

61 function removes a transition. The transitions() function returns the -

62 state's outgoing transitions. -

63 -

64 The assignProperty() function is used for defining property assignments that -

65 should be performed when a state is entered. -

66 -

67 Top-level states must be passed a QStateMachine object as their parent -

68 state, or added to a state machine using QStateMachine::addState(). -

69 -

70 \section1 States with Child States -

71 -

72 The childMode property determines how child states are treated. For -

73 non-parallel state groups, the setInitialState() function must be called to -

74 set the initial state. The child states are mutually exclusive states, and -

75 the state machine needs to know which child state to enter when the parent -

76 state is the target of a transition. -

77 -

78 The state emits the QState::finished() signal when a final child state -

79 (QFinalState) is entered. -

80 -

81 The setErrorState() sets the state's error state. The error state is the -

82 state that the state machine will transition to if an error is detected when -

83 attempting to enter the state (e.g. because no initial state has been set). -

84 -

86 -

87 /*! -

88 \property QState::initialState -

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

92 -

98 -

99 /*! -

100 \property QState::childMode -

101 -

102 \brief the child mode of this state -

103 -

104 The default value of this property is QState::ExclusiveStates. -

105 */ -

106 -

107 /*! -

108 \enum QState::ChildMode -

109 -

110 This enum specifies how a state's child states are treated. -

111 -

112 \value ExclusiveStates The child states are mutually exclusive and an -

113 initial state must be set by calling QState::setInitialState(). -

114 -

115 \value ParallelStates The child states are parallel. When the parent state -

116 is entered, all its child states are entered in parallel. -

117 */ -

118 -

119 /*! -

120 \enum QState::RestorePolicy -

121 -

122 This enum specifies the restore policy type. The restore policy -

123 takes effect when the machine enters a state which sets one or more -

124 properties. If the restore policy is set to RestoreProperties, -

125 the state machine will save the original value of the property before the -

126 new value is set. -

127 -

128 Later, when the machine either enters a state which does not set -

129 a value for the given property, the property will automatically be restored -

130 to its initial value. -

131 -

132 Only one initial value will be saved for any given property. If a value for a property has -

133 already been saved by the state machine, it will not be overwritten until the property has been -

134 successfully restored. -

135 -

136 \value DontRestoreProperties The state machine should not save the initial values of properties -

137 and restore them later. -

138 \value RestoreProperties The state machine should save the initial values of properties -

139 and restore them later. -
