The ColorRole enum defines the different symbolic color roles used in current GUIs.
The central roles are:
Константа | Значение | Описание |
---|---|---|
QPalette::Window | 10 | A general background color. |
QPalette::Background | Window | Это устаревшее значение. Use Window instead. |
QPalette::WindowText | 0 | A general foreground color. |
QPalette::Foreground | WindowText | Это устаревшее значение. Use WindowText instead. |
QPalette::Base | 9 | 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 | 16 | Used as the alternate background color in views with alternating row colors (see QAbstractItemView::setAlternatingRowColors()). |
QPalette::ToolTipBase | 18 | 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. |
QPalette::ToolTipText | 19 | 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. |
QPalette::Text | 6 | 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 | 1 | The general button background color. This background can be different from Window as some styles require a different background color for buttons. |
QPalette::ButtonText | 8 | A foreground color used with the Button color. |
QPalette::BrightText | 7 | 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.
Константа | Значение | Описание |
---|---|---|
QPalette::Light | 2 | Lighter than Button color. |
QPalette::Midlight | 3 | Between Button and Light. |
QPalette::Dark | 4 | Darker than Button. |
QPalette::Mid | 5 | Between Button and Dark. |
QPalette::Shadow | 11 | A very dark color. By default, the shadow color is Qt::black. |
Selected (marked) items have two roles:
Константа | Значение | Описание |
---|---|---|
QPalette::Highlight | 12 | A color to indicate a selected item or the current item. By default, the highlight color is Qt::darkBlue. |
QPalette::HighlightedText | 13 | A text color that contrasts with Highlight. By default, the highlighted text color is Qt::white. |
There are two color roles related to hyperlinks:
Константа | Значение | Описание |
---|---|---|
QPalette::Link | 14 | A text color used for unvisited hyperlinks. By default, the link color is Qt::blue. |
QPalette::LinkVisited | 15 | 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. Например:
QTextBrowser browser; QColor linkColor(Qt::red); QString sheet = QString::fromLatin1("a { text-decoration: underline; color: %1 }").arg(linkColor.name()); browser.document()->setDefaultStyleSheet(sheet);
Константа | Значение | Описание |

QPalette::NoRole | 17 | No role; this special role is often used to indicate that a role has not been assigned. |
