    QPalette

    概要

    函数

    详细描述

    PySide.QtGui.QPalette class contains color groups for each widget state.

    A palette consists of three color groups: Active , Disabled ，和 Inactive . All widgets in Qt contain a palette and use their palette to draw themselves. This makes the user interface easily configurable and easier to keep consistent.

    If you create a new widget we strongly recommend that you use the colors in the palette rather than hard-coding specific colors.

    The color groups:

    • The Active group is used for the window that has keyboard focus.
    • The Inactive group is used for other windows.
    • The Disabled group is used for widgets (not windows) that are disabled for some reason.

    Both active and inactive windows can contain disabled widgets. (Disabled widgets are often called inaccessible or grayed out .)

    In most styles, Active and Inactive look the same.

    Colors and brushes can be set for particular roles in any of a palette's color groups with PySide.QtGui.QPalette.setColor() and PySide.QtGui.QPalette.setBrush() . A color group contains a group of colors used by widgets for drawing themselves. We recommend that widgets use color group roles from the palette such as “foreground” and “base” rather than literal colors like “red” or “turquoise”. The color roles are enumerated and defined in the QPalette.ColorRole 文档编制。

    We strongly recommend that you use the default palette of the current style (returned by QApplication.palette() ) and modify that as necessary. This is done by Qt's widgets when they are drawn.

    To modify a color group you call the functions PySide.QtGui.QPalette.setColor() and PySide.QtGui.QPalette.setBrush() , depending on whether you want a pure color or a pixmap pattern.

    There are also corresponding PySide.QtGui.QPalette.color() and PySide.QtGui.QPalette.brush() getters, and a commonly used convenience function to get the QPalette.ColorRole for the current QPalette.ColorGroup : PySide.QtGui.QPalette.window() , PySide.QtGui.QPalette.windowText() , PySide.QtGui.QPalette.base() ，等。

    You can copy a palette using the copy constructor and test to see if two palettes are identical 使用 PySide.QtGui.QPalette.isCopyOf() .

    PySide.QtGui.QPalette is optimized by the use of 隐式共享 , so it is very efficient to pass PySide.QtGui.QPalette objects as arguments.

    警告

    Some styles do not use the palette for all drawing, for instance, if they make use of native theme engines. This is the case for both the Windows XP, Windows Vista, and the Mac OS X styles.

    PySide.QtGui.QBrush

    Constructs a palette from the button color. The other colors are automatically calculated, based on this color. Window will be the button color as well.

    This constructor is fast thanks to 隐式共享 .

    PySide.QtGui.QPalette. ColorGroup
    常量 描述
    QPalette.Disabled  
    QPalette.Active  
    QPalette.Inactive  
    QPalette.Normal synonym for Active
    PySide.QtGui.QPalette. ColorRole
    ../../_images/palette.png

    QPalette.ColorRole enum defines the different symbolic color roles used in current GUIs.

    The central roles are:

    常量 描述
    QPalette.Window A general background color.
    QPalette.Background This value is obsolete. Use Window instead.
    QPalette.WindowText A general foreground color.
    QPalette.Foreground This value is obsolete. Use WindowText 代替。
    QPalette.Base Used mostly as the background color for text entry widgets, but can also be used for other painting - such as the background of combobox drop down lists and toolbar handles. It is usually white or another light color.
    QPalette.AlternateBase Used as the alternate background color in views with alternating row colors (see QAbstractItemView.setAlternatingRowColors() ).
    QPalette.ToolTipBase Used as the background color for PySide.QtGui.QToolTip and PySide.QtGui.QWhatsThis . Tool tips use the Inactive color group of PySide.QtGui.QPalette , because tool tips are not active windows.
    QPalette.ToolTipText Used as the foreground color for PySide.QtGui.QToolTip and PySide.QtGui.QWhatsThis . Tool tips use the Inactive color group of PySide.QtGui.QPalette , because tool tips are not active windows.
    QPalette.Text The foreground color used with Base . This is usually the same as the WindowText , in which case it must provide good contrast with Window and Base .
    QPalette.Button The general button background color. This background can be different from Window as some styles require a different background color for buttons.
    QPalette.ButtonText A foreground color used with the Button 颜色。
    QPalette.BrightText A text color that is very different from WindowText , and contrasts well with e.g. Dark . Typically used for text that needs to be drawn where 文本 or WindowText would give poor contrast, such as on pressed push buttons. Note that text colors can be used for things other than just words; text colors are usually used for text, but it's quite common to use the text color roles for lines, icons, etc.

    There are some color roles used mostly for 3D bevel and shadow effects. All of these are normally derived from Window , and used in ways that depend on that relationship. For example, buttons depend on it to make the bevels look attractive, and Motif scroll bars depend on Mid to be slightly different from Window .

    常量 描述
    QPalette.Light Lighter than Button 颜色。
    QPalette.Midlight Between Button and Light .
    QPalette.Dark Darker than Button .
    QPalette.Mid Between Button and Dark .
    QPalette.Shadow A very dark color. By default, the shadow color is Qt.black .

    Selected (marked) items have two roles:

    常量 描述
    QPalette.Highlight A color to indicate a selected item or the current item. By default, the highlight color is Qt.darkBlue .
    QPalette.HighlightedText A text color that contrasts with Highlight . By default, the highlighted text color is Qt.white .

    There are two color roles related to hyperlinks:

    常量 描述
    QPalette.Link A text color used for unvisited hyperlinks. By default, the link color is Qt.blue .
    QPalette.LinkVisited A text color used for already visited hyperlinks. By default, the linkvisited color is Qt.magenta .

    Note that we do not use the Link and LinkVisited roles when rendering rich text in Qt, and that we recommend that you use CSS and the QTextDocument.setDefaultStyleSheet() function to alter the appearance of links. For example: 

    browser = QTextBrowser()
linkColor = QColor(Qt.red)
sheet = QString.fromLatin1("a { text-decoration: underline color: %1 }").arg(linkColor.name())
browser.document().setDefaultStyleSheet(sheet)
    常量 描述
    QPalette.NoRole No role; this special role is often used to indicate that a role has not been assigned.
