Description
The Qt class is a namespace for miscellaneous identifiers that need to be global-like.
Normally, you can ignore this class. QObject and a few other classes inherit it, so all the identifiers in the Qt namespace are normally usable without qualification.
However, you may occasionally need to say Qt::black instead of just black, particularly in static utility functions (such as many class factories).
See also Miscellaneous Classes.
Member Type Documentation
Qt::AlignmentFlags
This enum type is used to describe alignment. It contains horizontal and vertical flags.
The horizontal flags are:
- Qt::AlignAuto - Aligns according to the language. Left for most, right for Arabic and Hebrew.
- Qt::AlignLeft - Aligns with the left edge.
- Qt::AlignRight - Aligns with the right edge.
- Qt::AlignHCenter - Centers horizontally in the available space.
- Qt::AlignJustify - Justifies the text in the available space. Does not work for everything and may be interpreted as AlignAuto in some cases.
- The vertical flags are:
- Qt::AlignTop - Aligns with the top.
- Qt::AlignBottom - Aligns with the bottom.
- Qt::AlignVCenter - Centers vertically in the available space.
- You can use only one of the horizontal flags at a time. There is one two-dimensional flag:
- Qt::AlignCenter - Centers in both dimensions.
- You can use at most one horizontal and one vertical flag at a time. AlignCenter counts as both horizontal and vertical.
Masks:
- Qt::AlignHorizontal_Mask
- Qt::AlignVertical_Mask
- Conflicting combinations of flags have undefined meanings.
- Qt::AlignLeft - Aligns with the left edge.
Qt::AnchorAttribute
An anchor has one or more of the following attributes:
- Qt::AnchorName - the name attribute of the anchor. This attribute is used when scrolling to an anchor in the document.
- Qt::AnchorHref - the href attribute of the anchor. This attribute is used when a link is clicked to determine what content to load.
Qt::ArrowType
Qt::UpArrow
- Qt::DownArrow
- Qt::LeftArrow
- Qt::RightArrow
- Qt::LeftArrow
Qt::BGMode
Background mode
- Qt::TransparentMode
- Qt::OpaqueMode
Qt::BackgroundMode
This enum describes how the background of a widget changes, as the widget's palette changes.
The background is what the widget contains when paintEvent() is called. To minimize flicker, this should be the most common color or pixmap in the widget. For PaletteBackground, use colorGroup().brush( QColorGroup::Background ), and so on.
- Qt::PaletteForeground
- Qt::PaletteBackground
- Qt::PaletteButton
- Qt::PaletteLight
- Qt::PaletteMidlight
- Qt::PaletteDark
- Qt::PaletteMid
- Qt::PaletteText
- Qt::PaletteBrightText
- Qt::PaletteButtonText
- Qt::PaletteBase
- Qt::PaletteShadow
- Qt::PaletteHighlight
- Qt::PaletteHighlightedText
- Qt::PaletteLink
- Qt::PaletteLinkVisited
- Qt::X11ParentRelative - (internal use only)
- The final three values have special meaning:
- Qt::NoBackground - the widget is not cleared before paintEvent(). If the widget's paint event always draws on all the pixels, using this mode can be both fast and flicker-free.
- Qt::FixedColor - the widget is cleared to a fixed color, normally different from all the ones in the palette(). Set using setPaletteBackgroundColor().
- Qt::FixedPixmap - the widget is cleared to a fixed pixmap, normally different from all the ones in the palette(). Set using setPaletteBackgroundPixmap().
- Although FixedColor and FixedPixmap are sometimes just right, if you use them, make sure that you test your application when the desktop color scheme has been changed. (On X11, a quick way to test this is e.g. "./myapp -bg paleblue". On Windows, you must use the control panel.)
See also QWidget::backgroundMode, QWidget::backgroundMode, QWidget::setBackgroundPixmap(), and QWidget::paletteBackgroundColor.

Qt::ButtonState
This enum type describes the state of the mouse and the modifier buttons.
- Qt::NoButton - used when the button state does not refer to any button (see QMouseEvent::button()).
- Qt::LeftButton - set if the left button is pressed, or if this event refers to the left button. (The left button may be the right button on left-handed mice.)
- Qt::RightButton - the right button.
- Qt::MidButton - the middle button.
- Qt::ShiftButton - a Shift key on the keyboard is also pressed.
- Qt::ControlButton - a Ctrl key on the keyboard is also pressed.
- Qt::AltButton - an Alt key on the keyboard is also pressed.
- Qt::MetaButton - a Meta key on the keyboard is also pressed.
- Qt::Keypad - a keypad button is pressed.
- Qt::KeyButtonMask - a mask for ShiftButton, ControlButton, AltButton and MetaButton.
- Qt::MouseButtonMask - a mask for LeftButton, RightButton and MidButton.
- Qt::LeftButton - set if the left button is pressed, or if this event refers to the left button. (The left button may be the right button on left-handed mice.)
Qt::Corner
This enum type specifies a corner in a rectangle:
- Qt::TopLeft - top left corner
- Qt::TopRight - top right corner
- Qt::BottomLeft - bottom left corner
- Qt::BottomRight - bottom right corner
- Qt::TopRight - top right corner
Qt::CursorShape
This enum type defines the various cursors that can be used.
- Qt::ArrowCursor - standard arrow cursor
- Qt::UpArrowCursor - upwards arrow
- Qt::CrossCursor - crosshair
- Qt::WaitCursor - hourglass/watch
- Qt::BusyCursor - standard arrow with hourglass/watch
- Qt::IbeamCursor - ibeam/text entry
- Qt::SizeVerCursor - vertical resize
- Qt::SizeHorCursor - horizontal resize
- Qt::SizeFDiagCursor - diagonal resize (\)
- Qt::SizeBDiagCursor - diagonal resize (/)
- Qt::SizeAllCursor - all directions resize

- Qt::SplitHCursor - horizontal splitting
- Qt::PointingHandCursor - a pointing hand
- Qt::ForbiddenCursor - a slashed circle
- Qt::WhatsThisCursor - an arrow with a question mark
- Qt::BitmapCursor
- ArrowCursor is the default for widgets in a normal state.

Qt::DateFormat
Qt::TextDate - (default) Qt format
- Qt::ISODate - ISO 8601 extended format (YYYY-MM-DD, or with time, YYYY-MM-DDTHH:MM:SS)
- Qt::LocalDate - locale dependent format
Qt::Dock
Each dock window can be in one of the following positions:
- Qt::DockTop - above the central widget, below the menu bar.
- Qt::DockBottom - below the central widget, above the status bar.
- Qt::DockLeft - to the left of the central widget.
- Qt::DockRight - to the right of the central widget.
- Qt::DockMinimized - the dock window is not shown (this is effectively a 'hidden' dock area); the handles of all minimized dock windows are drawn in one row below the menu bar.
- Qt::DockTornOff - the dock window floats as its own top level window which always stays on top of the main window.
- Qt::DockUnmanaged - not managed by a QMainWindow.
- Qt::DockBottom - below the central widget, above the status bar.
Qt::GUIStyle
This type is obsolete. It is provided to keep old source working. We strongly advise against using it in new code.
- Qt::WindowsStyle
- Qt::MotifStyle
- Qt::MacStyle
- Qt::Win3Style
- Qt::PMStyle
- Qt::MotifStyle
Qt::ImageConversionFlags
The conversion flag is a bitwise-OR of the following values. The options marked "(default)" are set if no other values from the list are included (since the defaults are zero):
Color/Mono preference (ignored for QBitmap)
- Qt::AutoColor - (default) - If the image has depth 1 and contains only black and white pixels, the pixmap becomes monochrome.
- Qt::ColorOnly - The pixmap is dithered/converted to the native display depth.
- Qt::MonoOnly - The pixmap becomes monochrome. If necessary, it is dithered using the chosen dithering algorithm.
- Dithering mode preference for RGB channels
- Qt::DiffuseDither - (default) - A high-quality dither.
- Qt::OrderedDither - A faster, more ordered dither.
- Qt::ThresholdDither - No dithering; closest color is used.
- Dithering mode preference for alpha channel
- Qt::ThresholdAlphaDither - (default) - No dithering.
- Qt::OrderedAlphaDither - A faster, more ordered dither.
- Qt::DiffuseAlphaDither - A high-quality dither.
- Qt::NoAlpha - Not supported.
- Color matching versus dithering preference
- Qt::PreferDither - (default when converting to a pixmap) - Always dither 32-bit images when the image is converted to 8 bits.
- Qt::AvoidDither - (default when converting for the purpose of saving to file) - Dither 32-bit images only if the image has more than 256 colors and it is being converted to 8 bits.
- Qt::AutoDither - Not supported.
- The following are not values that are used directly, but masks for the above classes:
- Qt::ColorMode_Mask - Mask for the color mode.
- Qt::Dither_Mask - Mask for the dithering mode for RGB channels.
- Qt::AlphaDither_Mask - Mask for the dithering mode for the alpha channel.
- Qt::DitherMode_Mask - Mask for the mode that determines the preference of color matching versus dithering.
- Using 0 as the conversion flag sets all the default options.
- Qt::ColorOnly - The pixmap is dithered/converted to the native display depth.
