.SH "Qt::Dock"
Each dock window can be in one of the following positions:
.TP
\fCQt::DockTop\fR - above the central widget, below the menu bar.
.TP
\fCQt::DockBottom\fR - below the central widget, above the status bar.
.TP
\fCQt::DockLeft\fR - to the left of the central widget.
.TP
\fCQt::DockRight\fR - to the right of the central widget.
.TP
\fCQt::DockMinimized\fR - 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.
.TP
\fCQt::DockTornOff\fR - the dock window floats as its own top level window which always stays on top of the main window.
.TP
\fCQt::DockUnmanaged\fR - not managed by a QMainWindow.
.SH "Qt::GUIStyle"
\fBThis type is obsolete.\fR It is provided to keep old source working. We strongly advise against using it in new code.
.TP
\fCQt::WindowsStyle\fR
.TP
\fCQt::MotifStyle\fR
.TP
\fCQt::MacStyle\fR
.TP
\fCQt::Win3Style\fR
.TP
\fCQt::PMStyle\fR
.SH "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):
.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.
.SH "Qt::Key"
