Detailed Description

The QPalette class contains color groups for each widget state.

\inmodule QtGui

A palette consists of three color groups: Active, Disabled, and 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: \list

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. \endlist

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 setColor() and 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 \l ColorRole documentation.

We strongly recommend that you use the default palette of the current style (returned by QGuiApplication::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 setColor() and setBrush(), depending on whether you want a pure color or a pixmap pattern.

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

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

QPalette is optimized by the use of \l{implicit sharing}, so it is very efficient to pass QPalette objects as arguments.

Warning: 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 Vista and the \macos styles.

Color Roles

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

The central roles are:

\value Window A general background color.

\value WindowText A general foreground color.

\value 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.

\value AlternateBase Used as the alternate background color in views with alternating row colors (see QAbstractItemView::setAlternatingRowColors()).

\value ToolTipBase Used as the background color for QToolTip and QWhatsThis. Tool tips use the Inactive color group of QPalette, because tool tips are not active windows.

\value ToolTipText Used as the foreground color for QToolTip and QWhatsThis. Tool tips use the Inactive color group of QPalette, because tool tips are not active windows.

\value PlaceholderText Used as the placeholder color for various text input widgets. This enum value has been introduced in Qt 5.12

\value 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.

\value Button The general button background color. This background can be different from Window as some styles require a different background color for buttons.

\value ButtonText A foreground color used with the Button color.

\value 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 Text 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.

\value Light Lighter than Button color.

\value Midlight Between Button and Light.

\value Dark Darker than Button.

\value Mid Between Button and Dark.

\value Shadow A very dark color. By default, the shadow color is Qt::black.

Selected (marked) items have two roles:

\value Highlight A color to indicate a selected item or the current item. By default, the highlight color is Qt::darkBlue.

\value [since 6.6] Accent A color that typically contrasts or complements Base, Window and Button colors. It usually represents the users' choice of desktop personalisation. Styling of interactive components is a typical use case. Unless explicitly set, it defaults to Highlight.

\value 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:

\value Link A text color used for unvisited hyperlinks. By default, the link color is Qt::blue.

\value 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:

    QTextBrowser browser;
    QColor linkColor(Qt::red);
    QString sheet = QString::fromLatin1("a { text-decoration: underline; color: %1 }").arg(linkColor.name());
    browser.document()->setDefaultStyleSheet(sheet);

\value NoRole No role; this special role is often used to indicate that a role has not been assigned.

\omitvalue NColorRoles

Here is the call graph for this function:

◆ operator=()

QPalette & QPalette::operator= ( const QPalette & p )

Move-assigns other to this QPalette instance.

Assigns p to this palette and returns a reference to this palette.

Since: 5.2

This operation is fast thanks to \l{implicit sharing}.

Returns the placeholder text brush of the current color group.

Note: Before Qt 5.12, the placeholder text color was hard-coded as QPalette::text().color() with an alpha of 128 applied. In Qt 6, it is an independent color.
