.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 that all the identifiers in the Qt namespace are visible to you without qualification.
.PP
However, occasionally you may need to say \fCQt::black\fR instead just \fCblack,\fR particularly in static utility functions (such as many class factories).
.PP
Examples:
.(l
menu/menu.cpp
.)l
.SS "Member Type Documentation"
.SH "Qt::AlignmentFlags"
This enum type is used to describe alignment. It contains four sets of flags: Horizontal, vertical and modifying flags. The horizontal flags are: 
.TP
\fCAlignLeft\fR - Align with the left edge.
.TP
\fCAlignRight\fR - Align with the right edge.
.TP
\fCAlignHCenter\fR - Center horizontally in the available space.
.IP
The vertical flags are: 
.TP
\fCAlignTop\fR - Align with the top.
.TP
\fCAlignBottom\fR - Align with the bottom.
.TP
\fCAlignVCenter\fR - Center vertically in the available space.
.IP
You can only use one of the horizontal flags at a time. There is one two-dimensional flag: 
.TP
\fCAlignCenter\fR - Center in both dimensions.
.IP
This counts both as a horizontal and vertical flag: It cannot be combined with any other horizontal or vertical flags.
.PP
There are also some modifier flags. All of them apply only to printing: 
.TP
\fCSingleLine\fR - Treat all white-space as space and print just one line.
.TP
\fCDontClip\fR - If it's impossible to stay within the given bounds, print outside.
.TP
\fCExpandTabs\fR - Make the U+0009 (ascii tab) character move to the next tab stop.
.TP
\fCShowPrefix\fR - Display the string "&P" as an underlined P (see QButton for an example). To get an ampersand, use "&&".
.TP
\fCWordBreak\fR - Do line breaking at at appropriate points.
.IP
.PP
You can only use one of the horizontal flags at a time, and one of the vertical flags. \fCAlignCenter\fR counts as both horizontal and vertical. You can use as many modifier flags as you want, except that \fCSingleLine\fR and \fCWordBreak\fR cannot be combined.
.PP
Flags that are inappropriate for a given use (e.g. ShowPrefix to QGridLayout::addWidget()) are ignored.
.PP
Conflicting combinations of flags have undefined meanings.
.SH "Qt::ButtonState"
This enum type describes the state of the mouse buttons and the modifier buttons. The currently defined values are:
.TP
\fCNoButton\fR - used when the button state does not refer to any button (see QMouseEvent::button()).
.TP
\fCLeftButton\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
\fCRightButton\fR - the right button.
.TP
\fCMidButton\fR - the middle button
.TP
\fCShiftButton\fR - a shift key on the keyboard is also pressed.
.TP
\fCControlButton\fR - a control key on the keyboard is also pressed.
.TP
\fCAltButton\fR - an alt (or meta) key on the keyboard is also pressed.
.TP
\fCKeypad\fR - a keypad button is pressed.
.IP
.SH "Qt::Orientation"
This type is used to signify whether an object should be \fCHorizontal\fR or \fCVertical\fR (for example in QScrollBar).
.SH "Qt::PenCapStyle"
This enum type defines the pen cap styles supported by Qt; ie. what sorts of line end caps that can be drawn using QPainter. The available styles are: 
.TP
\fCFlatCap\fR - A square line end that does not cover the end point of the line.
.TP
\fCSquareCap\fR - A square line end that covers the end point and extends beyond it with half the line width.
.TP
