331 \class QPalette-
332-
333 \brief The QPalette class contains color groups for each widget state.-
334-
335 \inmodule QtGui-
336 \ingroup appearance-
337 \ingroup shared-
338-
339 A palette consists of three color groups: \e Active, \e Disabled,-
340 and \e Inactive. All widgets in Qt contain a palette and-
341 use their palette to draw themselves. This makes the user-
342 interface easily configurable and easier to keep consistent.-
343-
344-
345 If you create a new widget we strongly recommend that you use the-
346 colors in the palette rather than hard-coding specific colors.-
347-
348 The color groups:-
349 \list-
350 \li The Active group is used for the window that has keyboard focus.-
351 \li The Inactive group is used for other windows.-
352 \li The Disabled group is used for widgets (not windows) that are-
353 disabled for some reason.-
354 \endlist-
355-
356 Both active and inactive windows can contain disabled widgets.-
357 (Disabled widgets are often called \e inaccessible or \e{grayed-
358 out}.)-
359-
360 In most styles, Active and Inactive look the same.-
361-
362 Colors and brushes can be set for particular roles in any of a palette's-
363 color groups with setColor() and setBrush(). A color group contains a-
364 group of colors used by widgets for drawing themselves. We recommend that-
365 widgets use color group roles from the palette such as "foreground" and-
366 "base" rather than literal colors like "red" or "turquoise". The color-
367 roles are enumerated and defined in the \l ColorRole documentation.-
368-
369 We strongly recommend that you use the default palette of the-
370 current style (returned by QGuiApplication::palette()) and-
371 modify that as necessary. This is done by Qt's widgets when they-
372 are drawn.-
373-
374 To modify a color group you call the functions-
375 setColor() and setBrush(), depending on whether you want a pure-
376 color or a pixmap pattern.-
377-
378 There are also corresponding color() and brush() getters, and a-
379 commonly used convenience function to get the ColorRole for the current ColorGroup:-
380 window(), windowText(), base(), etc.-
381-
382-
383 You can copy a palette using the copy constructor and test to see-
384 if two palettes are \e identical using isCopyOf().-
385-
386 QPalette is optimized by the use of \l{implicit sharing},-
387 so it is very efficient to pass QPalette objects as arguments.-
388-
389 \warning Some styles do not use the palette for all drawing, for-
390 instance, if they make use of native theme engines. This is the-
391 case for both the Windows XP, Windows Vista, and the \macos-
392 styles.-

411 \enum QPalette::ColorRole-
412-
413 \image palette.png Color Roles-
414-
415 The ColorRole enum defines the different symbolic color roles used-
416 in current GUIs.-
417-
418 The central roles are:-
419-
420 \value Window A general background color.-
421-
422 \value Background This value is obsolete. Use Window instead.-
423-
424 \value WindowText A general foreground color.-
425-
426 \value Foreground This value is obsolete. Use WindowText instead.-
427-
428 \value Base Used mostly as the background color for text entry widgets,-
429 but can also be used for other painting - such as the-
430 background of combobox drop down lists and toolbar handles.-
431 It is usually white or another light color.-
432-
433 \value AlternateBase Used as the alternate background color in views with-
434 alternating row colors (see-
435 QAbstractItemView::setAlternatingRowColors()).-
436-
437 \value ToolTipBase Used as the background color for QToolTip and-
438 QWhatsThis. Tool tips use the Inactive color group-
439 of QPalette, because tool tips are not active-
440 windows.-
441-
442 \value ToolTipText Used as the foreground color for QToolTip and-
443 QWhatsThis. Tool tips use the Inactive color group-
444 of QPalette, because tool tips are not active-
445 windows.-
446-
447 \value Text The foreground color used with \c Base. This is usually-
448 the same as the \c WindowText, in which case it must provide-
449 good contrast with \c Window and \c Base.-
450-
451 \value Button The general button background color. This background can be different from-
452 \c Window as some styles require a different background color for buttons.-
453-
454 \value ButtonText A foreground color used with the \c Button color.-
455-
456 \value BrightText A text color that is very different from-
457 \c WindowText, and contrasts well with e.g. \c-
458 Dark. Typically used for text that needs to be-
459 drawn where \c Text or \c WindowText would give-
460 poor contrast, such as on pressed push buttons.-
461 Note that text colors can be used for things-
462 other than just words; text colors are \e-
463 usually used for text, but it's quite common to-
464 use the text color roles for lines, icons, etc.-
465-
466-
467 There are some color roles used mostly for 3D bevel and shadow effects.-
468 All of these are normally derived from \c Window, and used in ways that-
469 depend on that relationship. For example, buttons depend on it to make the-
470 bevels look attractive, and Motif scroll bars depend on \c Mid to be-
471 slightly different from \c Window.-
472-
473 \value Light Lighter than \c Button color.-
474-
475 \value Midlight Between \c Button and \c Light.-
476-
477 \value Dark Darker than \c Button.-
478-
479 \value Mid Between \c Button and \c Dark.-
480-
481 \value Shadow A very dark color. By default, the shadow color is-
482 Qt::black.-
483-
484-
485 Selected (marked) items have two roles:-
486-
487 \value Highlight A color to indicate a selected item or the current-
488 item. By default, the highlight color is-
489 Qt::darkBlue.-
490-
491 \value HighlightedText A text color that contrasts with \c Highlight.-
492 By default, the highlighted text color is Qt::white.-
493-
494 There are two color roles related to hyperlinks:-
495-
496 \value Link A text color used for unvisited hyperlinks.-
497 By default, the link color is Qt::blue.-
498-
499 \value LinkVisited A text color used for already visited hyperlinks.-
500 By default, the linkvisited color is Qt::magenta.-
501-
502 Note that we do not use the \c Link and \c LinkVisited roles when-
503 rendering rich text in Qt, and that we recommend that you use CSS-
504 and the QTextDocument::setDefaultStyleSheet() function to alter-
505 the appearance of links. For example:-
506-
507 \snippet textdocument-css/main.cpp 0-
508-
509 \value NoRole No role; this special role is often used to indicate that a-
510 role has not been assigned.-
