• GUI学习之二十九—QInputDialog学习总结


    最后一种对话框是QInputDialog,,用来提供个输入的窗口。

    一常用的静态方法

      由于输入的类型不同,QInputDialog分为多种静态方法使用

    #有步长调节器的整形数据,step为步长调节器的增量设定
    QInputDialog.getInt(parent: QWidget, title: str, label: str, value: int = ..., min: int = ..., max: int = ..., step: int = ..., flags: typing.Union[QtCore.Qt.WindowFlags, QtCore.Qt.WindowType] = ...)
    #有步长调节器的浮点形数据,decimals为小数位数
    QInputDialog.getDouble(parent: QWidget, title: str, label: str, value: float = ..., min: float = ..., max: float = ..., decimals: int = ..., flags: typing.Union[QtCore.Qt.WindowFlags, QtCore.Qt.WindowType] = ...)
    #单行文本数据,echo为输出模式(明文、密码或不显示)
    QInputDialog.getText(parent: QWidget, title: str, label: str, echo: 'QLineEdit.EchoMode' = ..., text: str = ..., flags: typing.Union[QtCore.Qt.WindowFlags, QtCore.Qt.WindowType] = ..., inputMethodHints: typing.Union[QtCore.Qt.InputMethodHints, QtCore.Qt.InputMethodHint] = ...)
    #多行文本
    QInputDialog.getMultiLineText(parent: QWidget, title: str, label: str, text: str = ..., flags: typing.Union[QtCore.Qt.WindowFlags, QtCore.Qt.WindowType] = ..., inputMethodHints: typing.Union[QtCore.Qt.InputMethodHints, QtCore.Qt.InputMethodHint] = ...)
    # #下拉列表,qizhong item为下拉列表的内容,迭代内从必须是字符串格式
    QInputDialog.getItem(parent: QWidget, title: str, label: str, items: typing.Iterable[str], current: int = ..., editable: bool = ..., flags: typing.Union[QtCore.Qt.WindowFlags, QtCore.Qt.WindowType] = ..., inputMethodHints: typing.Union[QtCore.Qt.InputMethodHints, QtCore.Qt.InputMethodHint] = ...)

    所有对话框都是有返回值的,返回的是个元祖,第一个元素就是input里对应的内容,第二个元素是个布尔量,如果对话框是按OK则返回1,取消就是返回0.

    二.功能作用

      1.构造函数

    QInputDialog(self, parent: typing.Optional[QWidget] = ..., flags: typing.Union[QtCore.Qt.WindowFlags, QtCore.Qt.WindowType] = ...)
    Window = ...  # type: 'Qt.WindowType'
    Dialog = ...  # type: 'Qt.WindowType'
    Sheet = ...  # type: 'Qt.WindowType'
    Drawer = ...  # type: 'Qt.WindowType'
    Popup = ...  # type: 'Qt.WindowType'
    Tool = ...  # type: 'Qt.WindowType'
    ToolTip = ...  # type: 'Qt.WindowType'
    SplashScreen = ...  # type: 'Qt.WindowType'
    Desktop = ...  # type: 'Qt.WindowType'
    SubWindow = ...  # type: 'Qt.WindowType'
    WindowType_Mask = ...  # type: 'Qt.WindowType'
    MSWindowsFixedSizeDialogHint = ...  # type: 'Qt.WindowType'
    MSWindowsOwnDC = ...  # type: 'Qt.WindowType'
    X11BypassWindowManagerHint = ...  # type: 'Qt.WindowType'
    FramelessWindowHint = ...  # type: 'Qt.WindowType'
    CustomizeWindowHint = ...  # type: 'Qt.WindowType'
    WindowTitleHint = ...  # type: 'Qt.WindowType'
    WindowSystemMenuHint = ...  # type: 'Qt.WindowType'
    WindowMinimizeButtonHint = ...  # type: 'Qt.WindowType'
    WindowMaximizeButtonHint = ...  # type: 'Qt.WindowType'
    WindowMinMaxButtonsHint = ...  # type: 'Qt.WindowType'
    WindowContextHelpButtonHint = ...  # type: 'Qt.WindowType'
    WindowShadeButtonHint = ...  # type: 'Qt.WindowType'
    WindowStaysOnTopHint = ...  # type: 'Qt.WindowType'
    WindowOkButtonHint = ...  # type: 'Qt.WindowType'
    WindowCancelButtonHint = ...  # type: 'Qt.WindowType'
    WindowStaysOnBottomHint = ...  # type: 'Qt.WindowType'
    WindowCloseButtonHint = ...  # type: 'Qt.WindowType'
    MacWindowToolBarButtonHint = ...  # type: 'Qt.WindowType'
    BypassGraphicsProxyWidget = ...  # type: 'Qt.WindowType'
    WindowTransparentForInput = ...  # type: 'Qt.WindowType'
    WindowOverridesSystemGestures = ...  # type: 'Qt.WindowType'
    WindowDoesNotAcceptFocus = ...  # type: 'Qt.WindowType'
    NoDropShadowWindowHint = ...  # type: 'Qt.WindowType'
    WindowFullscreenButtonHint = ...  # type: 'Qt.WindowType'
    ForeignWindow = ...  # type: 'Qt.WindowType'
    BypassWindowManagerHint = ...  # type: 'Qt.WindowType'
    CoverWindow = ...  # type: 'Qt.WindowType'
    MaximizeUsingFullscreenGeometryHint = ...  # type: 'Qt.WindowType'
    flag对应的枚举值

      要注意的就是flag(顶层窗口样式标志)对应的枚举值了。或者有几个最常用的效果在下面的setoption里也可以设置

      2.输入类型设置

    QInputDialog.setInputMode(self, mode: 'QInputDialog.InputMode')
    TextInput = ...  # type: 'QInputDialog.InputMode'
    IntInput = ...  # type: 'QInputDialog.InputMode'
    DoubleInput = ...  # type: 'QInputDialog.InputMode'

     主要要注意的是这里的类型里没有下拉列表,因为下拉列表是需要另外设置的

    QInputDialog.setComboBoxItems(self, items: typing.Iterable[str])
    QInputDialog.setComboBoxEditable()  #列表内容可编辑

      3.选项设置(输入类型)

    QInputDialog.setOption(self, option: 'QInputDialog.InputDialogOption', on: bool = ...)
    QInputDialog.setOptions(self, options: typing.Union[
    'QInputDialog.InputDialogOptions', 'QInputDialog.InputDialogOption']) QInputDialog.testOption(self, option: 'QInputDialog.InputDialogOption') -> bool: ... QInputDialog.options()-> 'QInputDialog.InputDialogOptions': ...
    NoButtons = ... # type: 'QInputDialog.InputDialogOption'
    UseListViewForComboBoxItems = ... # type: 'QInputDialog.InputDialogOption'
    UsePlainTextEditForTextInput = ... # type: 'QInputDialog.InputDialogOption'

      4.各种小分类的设置

    QInputDialog.setIntMaximum()
    QInputDialog.setIntMinimum()
    QInputDialog.setIntRange()
    QInputDialog.setIntStep()
    QInputDialog.setIntValue()
    整形数据
    QInputDialog.setDoubleMaximum()
    QInputDialog.setDoubleMinimum()
    QInputDialog.setDoubleRange()
    QInputDialog.setDoubleDecimals()
    QInputDialog.setDoubleValue()
    浮点型数据
    QInputDialog.setTextEchoMode()
    QInputDialog.setTextValue()
    字符串类型

      小种类的设置一定要和输入数据类型设置是一样的。否则是没有效果的(输入类型设置优先级高。)

    三.常用信号

    QInputDialog.intValueChanged()
    QInputDialog.intValueSelected()
    QInputDialog.doubleValueChanged()
    QInputDialog.doubleValueSelected()
    QInputDialog.textValueChanged()
    QInputDialog.textValueSelected()

    注意下区别,changed是只要值发生改变(不需要确认选择),而Select是只有点击确认按钮后才触发。但是都传递值作为参数。
