Detailed Description¶
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:
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 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 ColorRole
documentation.
We strongly recommend that you use the default palette of the current style (returned by 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 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.

When used as the palette of a QWidget
the colors are resolved as described by setPalette()
.

setPalette()
palette()
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.

- PySide6.QtGui.QPalette.ColorGroup¶
Constant
Description
QPalette.Disabled
QPalette.Active
QPalette.Inactive
QPalette.Normal
synonym for Active
- PySide6.QtGui.QPalette.ColorRole¶
The enum defines the different symbolic color roles used in current GUIs.
The central roles are:
Constant
Description
QPalette.Window
A general background color.
QPalette.WindowText
A general foreground color.
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
setAlternatingRowColors()
).QPalette.ToolTipBase
Used as the background color for
QToolTip
andQWhatsThis
. Tool tips use the Inactive color group ofQPalette
, because tool tips are not active windows.QPalette.ToolTipText
Used as the foreground color for
QToolTip
andQWhatsThis
. Tool tips use the Inactive color group ofQPalette
, because tool tips are not active windows.QPalette.PlaceholderText
Used as the placeholder color for various text input widgets. This enum value has been introduced in Qt 5.12
QPalette.Text
The foreground color used with
Base
. This is usually the same as theWindowText
, in which case it must provide good contrast withWindow
andBase
.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
color.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 whereText
orWindowText
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
.
Constant
Description
QPalette.Light
Lighter than
Button
color.QPalette.Midlight
Between
Button
andLight
.QPalette.Dark
Darker than
Button
.QPalette.Mid
Between
Button
andDark
.QPalette.Shadow
A very dark color. By default, the shadow color is
black
.
Selected (marked) items have two roles:
Constant
Description
QPalette.Highlight
A color to indicate a selected item or the current item. By default, the highlight color is
darkBlue
.QPalette.HighlightedText
A text color that contrasts with
Highlight
. By default, the highlighted text color iswhite
.
There are two color roles related to hyperlinks:
Constant
Description
QPalette.Link
A text color used for unvisited hyperlinks. By default, the link color is
blue
.QPalette.LinkVisited
A text color used for already visited hyperlinks. By default, the linkvisited color is
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 setDefaultStyleSheet()
function to alter the appearance of links. For example:
browser = QTextBrowser() linkColor = QColor(Qt.red) QString sheet = QString.fromLatin1("a { text-decoration: underline; color: %1 }").arg(linkColor.name()) browser.document().setDefaultStyleSheet(sheet)
Constant
Description
QPalette.NoRole
No role; this special role is often used to indicate that a role has not been assigned.
