.SH DESCRIPTION
The Qt class is a namespace for miscellaneous identifiers that need to be global-like.
.PP
Normally, you can ignore this class. QObject and a few other classes inherit it, so all the identifiers in the Qt namespace are usable without qualification.
.PP
However, you may occasionally need to say \fCQt::black\fR instead of just \fCblack\fR, particularly in static utility functions (such as many class factories).
.PP
See also Miscellaneous Classes.
.SS "Member Type Documentation"
.SH "Qt::AlignmentFlags"
This enum type is used to describe alignment. It contains horizontal and vertical flags. The horizontal flags are:
.TP
\fCQt::AlignAuto\fR - Aligns according to the language. Left for most, right for Hebrew and Arabic.
.TP
\fCQt::AlignLeft\fR - Aligns with the left edge.
.TP
\fCQt::AlignRight\fR - Aligns with the right edge.
.TP
\fCQt::AlignHCenter\fR - Centers horizontally in the available space.
.TP
\fCQt::AlignJustify\fR - Justifies the text in the available space. Does not work for everything and may be interpreted as AlignAuto in some cases.
.PP
The vertical flags are:
.TP
\fCQt::AlignTop\fR - Aligns with the top.
.TP
\fCQt::AlignBottom\fR - Aligns with the bottom.
.TP
\fCQt::AlignVCenter\fR - Centers vertically in the available space.
.PP
You can use only one of the horizontal flags at a time. There is one two-dimensional flag:
.TP
\fCQt::AlignCenter\fR - Centers in both dimensions.
.PP
You can use at most one horizontal and one vertical flag at a time. AlignCenter counts as both horizontal and vertical.
.PP
Masks:
.TP
\fCQt::AlignHorizontal_Mask\fR
.TP
\fCQt::AlignVertical_Mask\fR
.PP
Conflicting combinations of flags have undefined meanings.
.SH "Qt::ArrowType"
.TP
\fCQt::UpArrow\fR
.TP
\fCQt::DownArrow\fR
.TP
\fCQt::LeftArrow\fR
.TP
\fCQt::RightArrow\fR
.SH "Qt::BGMode"
Background mode
.TP
\fCQt::TransparentMode\fR
.TP
\fCQt::OpaqueMode\fR
.SH "Qt::BackgroundMode"
This enum describes how the background of a widget changes, as the widget's palette changes.
.PP
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. There are also three special values, listed at the end:
.TP
\fCQt::PaletteForeground\fR
.TP
\fCQt::PaletteBackground\fR
.TP
\fCQt::PaletteButton\fR
.TP
\fCQt::PaletteLight\fR
.TP
\fCQt::PaletteMidlight\fR
.TP
\fCQt::PaletteDark\fR
.TP
\fCQt::PaletteMid\fR
.TP
\fCQt::PaletteText\fR
.TP
\fCQt::PaletteBrightText\fR
.TP
\fCQt::PaletteButtonText\fR
.TP
\fCQt::PaletteBase\fR
.TP
\fCQt::PaletteShadow\fR
.TP
\fCQt::PaletteHighlight\fR
.TP
\fCQt::PaletteHighlightedText\fR
.TP
\fCQt::NoBackground\fR - 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.
.TP
\fCQt::FixedColor\fR - the widget is cleared to a fixed color, normally different from all the ones in the palette(). Set using setPaletteBackgroundColor(). 
.TP
\fCQt::FixedPixmap\fR - the widget is cleared to a fixed pixmap, normally different from all the ones in the palette(). Set using setBackgroundPixmap(). 
.TP
\fCQt::PaletteLink\fR
.TP
\fCQt::\fR - PaletteLinkVisited 
.TP
\fCQt::X11ParentRelative\fR - (internal use only)
.PP
Although FixedColor and FixedPixmap are sometimes just right, if you use them, make sure that your application looks right 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 have to use the control panel.)
.PP

.SH "Qt::ButtonState"
This enum type describes the state of the mouse buttons and the modifier buttons. The currently defined values are:
.TP
\fCQt::NoButton\fR - used when the button state does not refer to any button (see QMouseEvent::button()).
.TP
\fCQt::LeftButton\fR - set if the left button is pressed, or this event refers to the left button. Note that the left button may be the right button on left-handed mice.
.TP
\fCQt::RightButton\fR - the right button.
.TP
\fCQt::MidButton\fR - the middle button.
.TP
\fCQt::ShiftButton\fR - a Shift key on the keyboard is also pressed.
.TP
\fCQt::ControlButton\fR - a Ctrl key on the keyboard is also pressed.
.TP
\fCQt::AltButton\fR - an Alt (or Meta) key on the keyboard is also pressed.
.TP
\fCQt::MetaButton\fR - a Meta key on the keyboard is also pressed.
.TP
\fCQt::Keypad\fR - a keypad button is pressed.
.TP
\fCQt::KeyButtonMask\fR - is a mask for ShiftButton, ControlButton and AltButton.
.TP
\fCQt::MouseButtonMask\fR - is a mask for LeftButton, RightButton and MidButton.
.SH "Qt::CursorShape"
This enum type defines the various cursors that can be used.
.TP
\fCQt::ArrowCursor\fR - standard arrow cursor
.TP
\fCQt::UpArrowCursor\fR - upwards arrow
.TP
\fCQt::CrossCursor\fR - crosshair
.TP
\fCQt::WaitCursor\fR - hourglass/watch
.TP

.SH "Qt::ImageConversionFlags"
The conversion flag is a bitwise-OR of the following values. The options marked "(default)" are the set if no other values from the list are included (since the defaults are zero):
.PP
Color/Mono preference (ignored for QBitmap)
.TP
\fCQt::AutoColor\fR - (default) - If the image has depth 1 and contains only black and white pixels, the pixmap becomes monochrome.
.TP
\fCQt::ColorOnly\fR - The pixmap is dithered/converted to the native display depth.
.TP
\fCQt::MonoOnly\fR - The pixmap becomes monochrome. If necessary, it is dithered using the chosen dithering algorithm.
.PP
Dithering mode preference for RGB channels
.TP
\fCQt::DiffuseDither\fR - (default) - A high-quality dither.
.TP
\fCQt::OrderedDither\fR - A faster, more ordered dither.
.TP
\fCQt::ThresholdDither\fR - No dithering; closest color is used.
.PP
Dithering mode preference for alpha channel
.TP
\fCQt::ThresholdAlphaDither\fR - (default) - No dithering.
.TP
\fCQt::OrderedAlphaDither\fR - A faster, more ordered dither.
.TP
\fCQt::DiffuseAlphaDither\fR - A high-quality dither.
.TP
\fCQt::NoAlpha\fR - Not supported.
.PP
Color matching versus dithering preference
.TP
\fCQt::PreferDither\fR - (default when converting to a pixmap) - Always dither 32-bit images when the image is converted to 8 bits.
.TP
\fCQt::AvoidDither\fR - (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.
.TP
\fCQt::AutoDither\fR - Not supported.
.PP
The following are not values that are used directly, but masks for the above classes:
.TP
\fCQt::ColorMode_Mask\fR - Mask for the color mode.
.TP
\fCQt::Dither_Mask\fR - Mask for the dithering mode for RGB channels.
.TP
\fCQt::AlphaDither_Mask\fR - Mask for the dithering mode for the alpha channel.
.TP
\fCQt::DitherMode_Mask\fR - Mask for the mode that determines the preference of color matching versus dithering.
.PP
Using 0 as the conversion flag sets all the default options.
