继承者： QDateTimeEdit , QTimeEdit , QDateEdit , QDoubleSpinBox , QSpinBox
PySide.QtGui.QAbstractSpinBox class provides a spinbox and a line edit to display values.
此类被设计作为 Widget 的通用超类像 PySide.QtGui.QSpinBox , PySide.QtGui.QDoubleSpinBox and PySide.QtGui.QDateTimeEdit
这里是类的主要特性：
PySide.QtGui.QAbstractSpinBox provides a virtual PySide.QtGui.QAbstractSpinBox.stepBy() function that is called whenever the user triggers a step. This function takes an integer value to signify how many steps were taken. E.g. Pressing Qt.Key_Down will trigger a call to stepBy(-1).
PySide.QtGui.QAbstractSpinBox also provide a virtual function PySide.QtGui.QAbstractSpinBox.stepEnabled() to determine whether stepping up/down is allowed at any point. This function returns a bitset of StepEnabled .

acceptableInput() PySide.QtGui.QAbstractSpinBox.validate() PySide.QtGui.QAbstractSpinBox.fixup()
| 参数： | input – unicode |
|---|
This virtual function is called by the PySide.QtGui.QAbstractSpinBox 若 input is not validated to QValidator.Acceptable when Return is pressed or PySide.QtGui.QAbstractSpinBox.interpretText() is called. It will try to change the text so it is valid. Reimplemented in the various subclasses.
| 返回类型： | PySide.QtCore.bool |
|---|
This property holds whether the input satisfies the current validation.
| 返回类型： | PySide.QtCore.bool |
|---|
This property holds whether the spin box draws itself with a frame.
If enabled (the default) the spin box draws itself inside a frame, otherwise the spin box draws itself without any frame.
| 参数： | option – PySide.QtGui.QStyleOptionSpinBox |
|---|
初始化 option 采用值来自此 PySide.QtGui.QSpinBox 。此方法对子类是有用的，当需要 PySide.QtGui.QStyleOptionSpinBox ，但不希望自己填充所有信息。
This function interprets the text of the spin box. If the value has changed since last interpretation it will emit signals.
| 返回类型： | PySide.QtCore.bool |
|---|
This property holds whether the spin box will accelerate the frequency of the steps when pressing the step Up/Down buttons..
若启用，自旋框会更快地递增/递减值，当按下按钮时间越长时。
| 返回类型： | PySide.QtCore.bool |
|---|
This property holds whether the spin box is read only..
在只读模式下，用户仍可以将文本拷贝到剪贴板，或拖放文本；但无法编辑它。
PySide.QtGui.QLineEdit 在 PySide.QtGui.QAbstractSpinBox 在只读模式下不展示光标。

QLineEdit.readOnly
| 返回类型： | PySide.QtCore.bool |
|---|
This property holds whether keyboard tracking is enabled for the spinbox..
If keyboard tracking is enabled (the default), the spinbox emits the valueChanged() signal while the new value is being entered from the keyboard.
E.g. when the user enters the value 600 by typing 6, 0, and 0, the spinbox emits 3 signals with the values 6, 60, and 600 respectively.
If keyboard tracking is disabled, the spinbox doesn't emit the valueChanged() signal while typing. It emits the signal later, when the return key is pressed, when keyboard focus is lost, or when other spinbox functionality is used, e.g. pressing an arrow key.
| 返回类型： | PySide.QtGui.QLineEdit |
|---|
This function returns a pointer to the line edit of the spin box.
Selects all the text in the spinbox except the prefix and suffix.
| 参数： | on – PySide.QtCore.bool |
|---|
This property holds whether the spin box will accelerate the frequency of the steps when pressing the step Up/Down buttons..
若启用，自旋框会更快地递增/递减值，当按下按钮时间越长时。
| 参数： | flag – PySide.QtCore.Qt.Alignment |
|---|
This property holds the alignment of the spin box.
可能的值是 Qt.AlignLeft , Qt.AlignRight ，和 Qt.AlignHCenter .

acceptableInput() PySide.QtGui.QAbstractSpinBox.validate() PySide.QtGui.QAbstractSpinBox.fixup()
| 参数： | arg__1 – PySide.QtCore.bool |
|---|
This property holds whether the spin box draws itself with a frame.
If enabled (the default) the spin box draws itself inside a frame, otherwise the spin box draws itself without any frame.
| 参数： | kt – PySide.QtCore.bool |
|---|
This property holds whether keyboard tracking is enabled for the spinbox..
If keyboard tracking is enabled (the default), the spinbox emits the valueChanged() signal while the new value is being entered from the keyboard.
E.g. when the user enters the value 600 by typing 6, 0, and 0, the spinbox emits 3 signals with the values 6, 60, and 600 respectively.
If keyboard tracking is disabled, the spinbox doesn't emit the valueChanged() signal while typing. It emits the signal later, when the return key is pressed, when keyboard focus is lost, or when other spinbox functionality is used, e.g. pressing an arrow key.
| 参数： | edit – PySide.QtGui.QLineEdit |
|---|
Sets the line edit of the spinbox to be lineEdit instead of the current line edit widget. lineEdit can not be 0.
PySide.QtGui.QAbstractSpinBox takes ownership of the new lineEdit
若 QLineEdit.validator() 为 lineEdit returns 0, the internal validator of the spinbox will be set on the line edit.
| 参数： | r – PySide.QtCore.bool |
|---|
This property holds whether the spin box is read only..
在只读模式下，用户仍可以将文本拷贝到剪贴板，或拖放文本；但无法编辑它。
PySide.QtGui.QLineEdit 在 PySide.QtGui.QAbstractSpinBox 在只读模式下不展示光标。

QLineEdit.readOnly
| 参数： | txt – unicode |
|---|
This property holds the special-value text.
若设置，自旋框会显示此文本而非数字值，在当前值等于 minimum() 时。典型用途是指示此抉择具有特殊 (默认) 含义。
例如，若自旋框允许用户选取比例因子 (或缩放级别) 为显示图像，且应用程序能够自动选取允许把图像完整拟合在显示窗口中的某一值，就可以像这样设置自旋框：
zoomSpinBox = QSpinBox()
zoomSpinBox.setRange(0, 1000)
zoomSpinBox.setSingleStep(10)
zoomSpinBox.setSuffix("%")
zoomSpinBox.setSpecialValueText(tr("Automatic"))
zoomSpinBox.setValue(100)
The user will then be able to choose a scale from 1% to 1000% or select “Auto” to leave it up to the application to choose. Your code must then interpret the spin box value of 0 as a request from the user to scale the image to fit inside the window.
所有被显示值带前缀和后缀 (若有设置)， except 为特殊值，仅展示特殊值文本。此特殊文本被传入 QSpinBox.valueChanged() signal that passes a PySide.QtCore.QString .
要关闭特殊值文本显示，调用此函数采用空字符串。默认为无特殊值文本 (即：照常展示数字值)。
If no special-value text is set, PySide.QtGui.QAbstractSpinBox.specialValueText() returns an empty string.
| 参数： | w – PySide.QtCore.bool |
|---|
This property holds whether the spin box is circular..
If wrapping is true stepping up from maximum() value will take you to the minimum() value and vica versa. Wrapping only make sense if you have minimum() and maximum() values set.
spinBox = QSpinBox(self)
spinBox.setRange(0, 100)
spinBox.setWrapping(True)
spinBox.setValue(100)
spinBox.stepBy(1)
// value is 0
| 返回类型： | unicode |

| 参数： | steps – PySide.QtCore.int |
|---|
Virtual function that is called whenever the user triggers a step. The steps parameter indicates how many steps were taken, e.g. Pressing Qt.Key_Down will trigger a call to stepBy(-1), whereas pressing Qt.Key_Prior will trigger a call to stepBy(10).
If you subclass PySide.QtGui.QAbstractSpinBox you must reimplement this function. Note that this function is called even if the resulting value will be outside the bounds of minimum and maximum. It's this function's job to handle these situations.
Steps down by one linestep Calling this slot is analogous to calling stepBy(-1);
| 返回类型： | PySide.QtGui.QAbstractSpinBox.StepEnabled |
|---|
Virtual function that determines whether stepping up and down is legal at any given time.
The up arrow will be painted as disabled unless ( PySide.QtGui.QAbstractSpinBox.stepEnabled() & StepUpEnabled ) != 0.
The default implementation will return ( StepUpEnabled | StepDownEnabled ) if wrapping is turned on. Else it will return StepDownEnabled if value is > minimum() or'ed with StepUpEnabled if value < maximum().
If you subclass PySide.QtGui.QAbstractSpinBox you will need to reimplement this function.
Steps up by one linestep Calling this slot is analogous to calling stepBy(1);
| 返回类型： | unicode |
|---|
This property holds the spin box's text, including any prefix and suffix.
没有默认文本。
| 参数： |
|
|---|---|
| 返回类型： |
PyObject |
This virtual function is called by the PySide.QtGui.QAbstractSpinBox to determine whether input is valid. The pos parameter indicates the position in the string. Reimplemented in the various subclasses.
| 返回类型： | PySide.QtCore.bool |
|---|
This property holds whether the spin box is circular..
If wrapping is true stepping up from maximum() value will take you to the minimum() value and vica versa. Wrapping only make sense if you have minimum() and maximum() values set.
spinBox = QSpinBox(self)
spinBox.setRange(0, 100)
spinBox.setWrapping(True)
spinBox.setValue(100)
spinBox.stepBy(1)
// value is 0
