DESCRIPTION
       The QFrame class is the base class of widgets that can have a frame.

       It draws a frame and calls a virtual function, drawContents(), to fill in the frame. This
       function is reimplemented by subclasses. There are also two other less useful functions:
       drawFrame() and frameChanged().

       QPopupMenu uses this to "raise" the menu above the surrounding screen. QProgressBar has a
       "sunken" look. QLabel has a flat look. The frames of widgets like these can be changed.

	   QLabel label(...);
	   label.setFrameStyle( QFrame::Panel | QFrame::Raised );
	   label.setLineWidth( 2 );
	   QProgressBar pbar(...);
	   label.setFrameStyle( QFrame::NoFrame );

       The QFrame class can also be used directly for creating simple frames without any
       contents, although usually you would use a QHBox or QVBox because they automatically lay
       out the widgets you put inside the frame.

       A frame widget has four attributes: frameStyle(), lineWidth(), midLineWidth(), and
       margin().

       The frame style is specified by a frame shape and a shadow style. The frame shapes are
       NoFrame, Box, Panel, StyledPanel, PopupPanel, WinPanel, ToolBarPanel, MenuBarPanel, HLine
       and VLine; the shadow styles are Plain, Raised and Sunken.

       The line width is the width of the frame border.

       The mid-line width specifies the width of an extra line in the middle of the frame, which
       uses a third color to obtain a special 3D effect. Notice that a mid-line is only drawn for
       Box, HLine and VLine frames that are raised or sunken.

       The margin is the gap between the frame and the contents of the frame.

       This table shows the most useful combinations of styles and widths (and some rather
       useless ones):

   Member Type Documentation
QFrame::Shadow
       This enum type defines the 3D effect used for QFrame's frame.

       QFrame::Plain - the frame and contents appear level with the surroundings; draws using the
       palette foreground color (without any 3D effect)

       QFrame::Raised - the frame and contents appear raised; draws a 3D raised line using the
       light and dark colors of the current color group

       QFrame::Sunken - the frame and contents appear sunken; draws a 3D sunken line using the
       light and dark colors of the current color group

       QFrame::MShadow - internal; mask for the shadow

       Shadow interacts with QFrame::Shape, the lineWidth() and the midLineWidth(). See the
       picture of the frames in the class description.

       See also QFrame::Shape, lineWidth, and midLineWidth.

QFrame::Shape
       This enum type defines the shapes of a QFrame's frame.

       QFrame::NoFrame - QFrame draws nothing

       QFrame::Box - QFrame draws a box around its contents

       QFrame::Panel - QFrame draws a panel to make the contents appear raised or sunken

       QFrame::StyledPanel - draws a rectangular panel with a look that depends on the current
       GUI style. It can be raised or sunken.

       QFrame::HLine - QFrame draws a horizontal line that frames nothing (useful as separator)

       QFrame::VLine - QFrame draws a vertical line that frames nothing (useful as separator)

       QFrame::GroupBoxPanel - draws a rectangular panel

       QFrame::WinPanel - draws a rectangular panel that can be raised or sunken like those in
       Windows 95. Specifying this shape sets the line width to 2 pixels. WinPanel is provided
       for compatibility. For GUI style independence we recommend using StyledPanel instead.

       QFrame::ToolBarPanel

       QFrame::MenuBarPanel

       QFrame::PopupPanel

       QFrame::LineEditPanel - is used to draw a frame suitable for line edits. The look depends
       upon the current GUI style.

       QFrame::TabWidgetPanel - is used to draw a frame suitable for tab widgets. The look
       depends upon the current GUI style.

       QFrame::MShape - internal mask

       When it does not call QStyle, Shape interacts with QFrame::Shadow, the lineWidth() and the
       midLineWidth() to create the total result. See the picture of the frames in the class
       description.

       See also QFrame::Shadow, QFrame::style(), and QStyle::drawPrimitive().

MEMBER FUNCTION DOCUMENTATION
QFrame::QFrame ( QWidget * parent = 0, const char * name = 0, WFlags f = 0 )
       Constructs a frame widget with frame style NoFrame and a 1-pixel frame width.

       The parent, name and f arguments are passed to the QWidget constructor.

QRect QFrame::contentsRect () const
       Returns the rectangle inside the frame. See the "contentsRect" property for details.

void QFrame::drawContents ( QPainter * ) [virtual protected]
       Virtual function that draws the contents of the frame.

       The QPainter is already open when you get it, and you must leave it open. Painter
       transformations are switched off on entry. If you transform the painter, remember to take
       the frame into account and reset transformation before returning.

       This function is reimplemented by subclasses that draw something inside the frame. It
       should only draw inside contentsRect(). The default function does nothing.

       See also contentsRect and QPainter::setClipRect().

       Reimplemented in QLabel, QLCDNumber, QMenuBar, and QPopupMenu.

void QFrame::drawFrame ( QPainter * p ) [virtual protected]
       Draws the frame using the painter p and the current frame attributes and color group. The
       rectangle inside the frame is not affected.

       This function is virtual, but in general you do not need to reimplement it. If you do,
       note that the QPainter is already open and must remain open.

       See also frameRect, contentsRect, drawContents(), frameStyle(), and palette.

void QFrame::frameChanged () [virtual protected]
       Virtual function that is called when the frame style, line width or mid-line width
       changes.

       This function can be reimplemented by subclasses that need to know when the frame
       attributes change.

       The default implementation calls update().

QRect QFrame::frameRect () const
       Returns the frame rectangle. See the "frameRect" property for details.

Shadow QFrame::frameShadow () const
       Returns the frame shadow value from the frame style. See the "frameShadow" property for
       details.

Shape QFrame::frameShape () const
       Returns the frame shape value from the frame style. See the "frameShape" property for
       details.

int QFrame::frameStyle () const
       Returns the frame style.

       The default value is QFrame::NoFrame.

       See also setFrameStyle(), frameShape, and frameShadow.

       Example: scrollview/scrollview.cpp.

int QFrame::frameWidth () const
       Returns the width of the frame that is drawn. See the "frameWidth" property for details.

int QFrame::lineWidth () const
       Returns the line width. See the "lineWidth" property for details.

int QFrame::margin () const
       Returns the width of the margin. See the "margin" property for details.

int QFrame::midLineWidth () const
       Returns the width of the mid-line. See the "midLineWidth" property for details.

void QFrame::paintEvent ( QPaintEvent * event ) [virtual protected]
       Processes the paint event event.

       Paints the frame and the contents.

       Opens the painter on the frame and calls drawFrame(), then drawContents().

       Examples:

       Reimplemented from QWidget.

void QFrame::resizeEvent ( QResizeEvent * e ) [virtual protected]
       Processes the resize event e.

       Adjusts the frame rectangle for the resized widget. The frame rectangle is elastic, and
       the surrounding area is static.

       The resulting frame rectangle may be null or invalid. You can use setMinimumSize() to
       avoid those possibilities.

       Nothing is done if the frame rectangle is a null rectangle already.

       Example: life/life.cpp.

       Reimplemented from QWidget.

void QFrame::setFrameRect ( const QRect & ) [virtual]
       Sets the frame rectangle. See the "frameRect" property for details.

void QFrame::setFrameShadow ( Shadow )
       Sets the frame shadow value from the frame style. See the "frameShadow" property for
       details.

void QFrame::setFrameShape ( Shape )
       Sets the frame shape value from the frame style. See the "frameShape" property for
       details.

void QFrame::setFrameStyle ( int style ) [virtual]
       Sets the frame style to style.

       The style is the bitwise OR between a frame shape and a frame shadow style. See the
       illustration in the class documentation.

       The frame shapes are given in QFrame::Shape and the shadow styles in QFrame::Shadow.

       If a mid-line width greater than 0 is specified, an additional line is drawn for Raised or
       Sunken Box, HLine, and VLine frames. The mid-color of the current color group is used for
       drawing middle lines.

       See also Illustration, frameStyle(), colorGroup, and QColorGroup.

       Examples:

void QFrame::setLineWidth ( int ) [virtual]
       Sets the line width. See the "lineWidth" property for details.

void QFrame::setMargin ( int ) [virtual]
       Sets the width of the margin. See the "margin" property for details.

void QFrame::setMidLineWidth ( int ) [virtual]
       Sets the width of the mid-line. See the "midLineWidth" property for details.

   Property Documentation
QRect contentsRect
       This property holds the rectangle inside the frame.

       Get this property's value with contentsRect().

       See also frameRect and drawContents().

QRect frameRect
       This property holds the frame rectangle.

       The frame rectangle is the rectangle the frame is drawn in. By default, this is the entire
       widget. Setting this property does not cause a widget update.

       If this property is set to a null rectangle (for example QRect(0, 0, 0, 0)), then the
       frame rectangle is equivalent to the widget rectangle.

       See also contentsRect.

       Set this property's value with setFrameRect() and get this property's value with
       frameRect().

Shadow frameShadow
       This property holds the frame shadow value from the frame style.

       Set this property's value with setFrameShadow() and get this property's value with
       frameShadow().

       See also frameStyle() and frameShape.

Shape frameShape
       This property holds the frame shape value from the frame style.

       Set this property's value with setFrameShape() and get this property's value with
       frameShape().

       See also frameStyle() and frameShadow.

int frameWidth
       This property holds the width of the frame that is drawn.

       Note that the frame width depends on the frame style, not only the line width and the mid-
       line width. For example, the style NoFrame always has a frame width of 0, whereas the
       style Panel has a frame width equivalent to the line width. The frame width also includes
       the margin.

       See also lineWidth, midLineWidth, frameStyle(), and margin.

       Get this property's value with frameWidth().

int lineWidth
       This property holds the line width.

       Note that the total line width for HLine and VLine is given by frameWidth(), not
       lineWidth().

       The default value is 1.

       See also midLineWidth and frameWidth.

       Set this property's value with setLineWidth() and get this property's value with
       lineWidth().

int margin
       This property holds the width of the margin.

       The margin is the distance between the innermost pixel of the frame and the outermost
       pixel of contentsRect(). It is included in frameWidth().

       The margin is filled according to backgroundMode().

       The default value is 0.

       See also margin, lineWidth, and frameWidth.

       Set this property's value with setMargin() and get this property's value with margin().

int midLineWidth
       This property holds the width of the mid-line.

       The default value is 0.

       See also lineWidth and frameWidth.

       Set this property's value with setMidLineWidth() and get this property's value with
       midLineWidth().
