\class QStyle
\brief The QStyle class is an abstract base class that encapsulates the look and feel of a GUI.
\ingroup appearance
Qt contains a set of QStyle subclasses that emulate the styles of
the different platforms supported by Qt (QWindowsStyle,
QMacStyle, QMotifStyle, etc.). By default, these styles are built
into the QtGui library. Styles can also be made available as
plugins.
Qt's built-in widgets use QStyle to perform nearly all of their
drawing, ensuring that they look exactly like the equivalent
native widgets. The diagram below shows a QComboBox in eight
different styles.
\img qstyle-comboboxes.png Eight combo boxes
Topics:
\tableofcontents
\section1 Setting a Style
The style of the entire application can be set using the
QApplication::setStyle() function. It can also be specified by the
user of the application, using the \c -style command-line option:
\snippet doc/src/snippets/code/src_gui_styles_qstyle.cpp 0
If no style is specified, Qt will choose the most appropriate
style for the user's platform or desktop environment.
A style can also be set on an individual widget using the
QWidget::setStyle() function.
\section1 Developing Style-Aware Custom Widgets
If you are developing custom widgets and want them to look good on
all platforms, you can use QStyle functions to perform parts of
the widget drawing, such as drawItemText(), drawItemPixmap(),
drawPrimitive(), drawControl(), and drawComplexControl().
Most QStyle draw functions take four arguments:
\list
\o an enum value specifying which graphical element to draw
\o a QStyleOption specifying how and where to render that element
\o a QPainter that should be used to draw the element
\o a QWidget on which the drawing is performed (optional)
\endlist
For example, if you want to draw a focus rectangle on your
widget, you can write:
\snippet doc/src/snippets/styles/styles.cpp 1
QStyle gets all the information it needs to render the graphical
element from QStyleOption. The widget is passed as the last
argument in case the style needs it to perform special effects
(such as animated default buttons on Mac OS X), but it isn't
mandatory. In fact, you can use QStyle to draw on any paint
device, not just widgets, by setting the QPainter properly.
QStyleOption has various subclasses for the various types of
graphical elements that can be drawn. For example,
PE_FrameFocusRect expects a QStyleOptionFocusRect argument.
To ensure that drawing operations are as fast as possible,
QStyleOption and its subclasses have public data members. See the
QStyleOption class documentation for details on how to use it.
For convenience, Qt provides the QStylePainter class, which
combines a QStyle, a QPainter, and a QWidget. This makes it
possible to write
\snippet doc/src/snippets/styles/styles.cpp 5
\dots
\snippet doc/src/snippets/styles/styles.cpp 7
instead of
\snippet doc/src/snippets/styles/styles.cpp 2
\dots
\snippet doc/src/snippets/styles/styles.cpp 3
\section1 Creating a Custom Style
You can create a custom look and feel for your application by
creating a custom style. There are two approaches to creating a
custom style. In the static approach, you either choose an
existing QStyle class, subclass it, and reimplement virtual
functions to provide the custom behavior, or you create an entire
QStyle class from scratch. In the dynamic approach, you modify the
behavior of your system style at runtime. The static approach is
described below. The dynamic approach is described in QProxyStyle.
The first step in the static approach is to pick one of the styles
provided by Qt from which you will build your custom style. Your
choice of QStyle class will depend on which style resembles your
desired style the most. The most general class that you can use as
a base is QCommonStyle (not QStyle). This is because Qt requires
its styles to be \l{QCommonStyle}s.
Depending on which parts of the base style you want to change,
you must reimplement the functions that are used to draw those
parts of the interface. To illustrate this, we will modify the
look of the spin box arrows drawn by QWindowsStyle. The arrows
are \e{primitive elements} that are drawn by the drawPrimitive()
function, so we need to reimplement that function. We need the
following class declaration:
\snippet doc/src/snippets/customstyle/customstyle.h 0
To draw its up and down arrows, QSpinBox uses the
PE_IndicatorSpinUp and PE_IndicatorSpinDown primitive elements.
Here's how to reimplement the drawPrimitive() function to draw
them differently:
\snippet doc/src/snippets/customstyle/customstyle.cpp 2
\snippet doc/src/snippets/customstyle/customstyle.cpp 3
\snippet doc/src/snippets/customstyle/customstyle.cpp 4
Notice that we don't use the \c widget argument, except to pass it
on to the QWindowStyle::drawPrimitive() function. As mentioned
earlier, the information about what is to be drawn and how it
should be drawn is specified by a QStyleOption object, so there is
no need to ask the widget.
If you need to use the \c widget argument to obtain additional
information, be careful to ensure that it isn't 0 and that it is
of the correct type before using it. For example:
\snippet doc/src/snippets/customstyle/customstyle.cpp 0
\dots
\snippet doc/src/snippets/customstyle/customstyle.cpp 1
When implementing a custom style, you cannot assume that the
widget is a QSpinBox just because the enum value is called
PE_IndicatorSpinUp or PE_IndicatorSpinDown.
The documentation for the \l{widgets/styles}{Styles} example
covers this topic in more detail.
\warning Qt style sheets are currently not supported for custom QStyle
subclasses. We plan to address this in some future release.
\section1 Using a Custom Style
There are several ways of using a custom style in a Qt
application. The simplest way is to pass the custom style to the
QApplication::setStyle() static function before creating the
QApplication object:
\snippet snippets/customstyle/main.cpp using a custom style
You can call QApplication::setStyle() at any time, but by calling
it before the constructor, you ensure that the user's preference,
set using the \c -style command-line option, is respected.
You may want to make your custom style available for use in other
applications, which may not be yours and hence not available for
you to recompile. The Qt Plugin system makes it possible to create
styles as plugins. Styles created as plugins are loaded as shared
objects at runtime by Qt itself. Please refer to the \link
plugins-howto.html Qt Plugin\endlink documentation for more
information on how to go about creating a style plugin.
Compile your plugin and put it into Qt's \c plugins/styles
directory. We now have a pluggable style that Qt can load
automatically. To use your new style with existing applications,
simply start the application with the following argument:
\snippet doc/src/snippets/code/src_gui_styles_qstyle.cpp 1
The application will use the look and feel from the custom style you
implemented.
\section1 Right-to-Left Desktops
Languages written from right to left (such as Arabic and Hebrew)
usually also mirror the whole layout of widgets, and require the
light to come from the screen's top-right corner instead of
top-left.
If you create a custom style, you should take special care when
drawing asymmetric elements to make sure that they also look
correct in a mirrored layout. An easy way to test your styles is
to run applications with the \c -reverse command-line option or
to call QApplication::setLayoutDirection() in your \c main()
function.
Here are some things to keep in mind when making a style work well in a
right-to-left environment:
\list
\o subControlRect() and subElementRect() return rectangles in screen coordinates
\o QStyleOption::direction indicates in which direction the item should be drawn in
\o If a style is not right-to-left aware it will display items as if it were left-to-right
\o visualRect(), visualPos(), and visualAlignment() are helpful functions that will
translate from logical to screen representations.
\o alignedRect() will return a logical rect aligned for the current direction
\endlist
\section1 Styles in Item Views
The painting of items in views is performed by a delegate. Qt's
default delegate, QStyledItemDelegate, is also used for for calculating bounding
rectangles of items, and their sub-elements for the various kind
of item \l{Qt::ItemDataRole}{data roles}
QStyledItemDelegate supports. See the QStyledItemDelegate class
description to find out which datatypes and roles are supported. You
can read more about item data roles in \l{Model/View Programming}.
When QStyledItemDelegate paints its items, it draws
CE_ItemViewItem, and calculates their size with CT_ItemViewItem.
Note also that it uses SE_ItemViewItemText to set the size of
editors. When implementing a style to customize drawing of item
views, you need to check the implementation of QCommonStyle (and
any other subclasses from which your style
inherits). This way, you find out which and how
other style elements are painted, and you can then reimplement the
painting of elements that should be drawn differently.
We include a small example where we customize the drawing of item
backgrounds.
\snippet doc/src/snippets/customviewstyle.cpp 0
The primitive element PE_PanelItemViewItem is responsible for
painting the background of items, and is called from
\l{QCommonStyle}'s implementation of CE_ItemViewItem.
To add support for drawing of new datatypes and item data roles,
it is necessary to create a custom delegate. But if you only
need to support the datatypes implemented by the default
delegate, a custom style does not need an accompanying
delegate. The QStyledItemDelegate class description gives more
information on custom delegates.
The drawing of item view headers is also done by the style, giving
control over size of header items and row and column sizes.

actions in this function might be to call the
QWidget::setBackgroundMode() function for the widget. Do not use
the function to set, for example, the geometry. Reimplementing
this function provides a back-door through which the appearance
of a widget can be changed, but with Qt's style engine it is
rarely necessary to implement this function; reimplement
drawItemPixmap(), drawItemText(), drawPrimitive(), etc. instead.
The QWidget::inherits() function may provide enough information to
allow class-specific customizations. But because new QStyle
subclasses are expected to work reasonably with all current and \e
future widgets, limited use of hard-coded customization is
recommended.

\class QAbstractButton
\brief The QAbstractButton class is the abstract base class of
button widgets, providing functionality common to buttons.
\ingroup abstractwidgets
This class implements an \e abstract button.
Subclasses of this class handle user actions, and specify how the button
is drawn.
QAbstractButton provides support for both push buttons and checkable
(toggle) buttons. Checkable buttons are implemented in the QRadioButton
and QCheckBox classes. Push buttons are implemented in the
QPushButton and QToolButton classes; these also provide toggle
behavior if required.
Any button can display a label containing text and an icon. setText()
sets the text; setIcon() sets the icon. If a button is disabled, its label
is changed to give the button a "disabled" appearance.
If the button is a text button with a string containing an
ampersand ('&'), QAbstractButton automatically creates a shortcut
key. For example:
\snippet doc/src/snippets/code/src_gui_widgets_qabstractbutton.cpp 0
The \key Alt+C shortcut is assigned to the button, i.e., when the
user presses \key Alt+C the button will call animateClick(). See
the \l {QShortcut#mnemonic}{QShortcut} documentation for details
(to display an actual ampersand, use '&&').
You can also set a custom shortcut key using the setShortcut()
function. This is useful mostly for buttons that do not have any
text, because they have no automatic shortcut.
\snippet doc/src/snippets/code/src_gui_widgets_qabstractbutton.cpp 1
All of the buttons provided by Qt (QPushButton, QToolButton,
QCheckBox, and QRadioButton) can display both \l text and \l{icon}{icons}.
A button can be made the default button in a dialog are provided by
QPushButton::setDefault() and QPushButton::setAutoDefault().
QAbstractButton provides most of the states used for buttons:
\list
\o isDown() indicates whether the button is \e pressed down.
\o isChecked() indicates whether the button is \e checked. Only
checkable buttons can be checked and unchecked (see below).
\o isEnabled() indicates whether the button can be pressed by the
user. \note As opposed to other widgets, buttons derived from
QAbstractButton accepts mouse and context menu events
when disabled.
\o setAutoRepeat() sets whether the button will auto-repeat if the
user holds it down. \l autoRepeatDelay and \l autoRepeatInterval
define how auto-repetition is done.
\o setCheckable() sets whether the button is a toggle button or not.
\endlist
The difference between isDown() and isChecked() is as follows.
When the user clicks a toggle button to check it, the button is first
\e pressed then released into the \e checked state. When the user
clicks it again (to uncheck it), the button moves first to the
\e pressed state, then to the \e unchecked state (isChecked() and
isDown() are both false).
QAbstractButton provides four signals:
\list 1
\o pressed() is emitted when the left mouse button is pressed while
the mouse cursor is inside the button.
\o released() is emitted when the left mouse button is released.
\o clicked() is emitted when the button is first pressed and then
released, when the shortcut key is typed, or when click() or
animateClick() is called.
\o toggled() is emitted when the state of a toggle button changes.
\endlist
To subclass QAbstractButton, you must reimplement at least
paintEvent() to draw the button's outline and its text or pixmap. It
is generally advisable to reimplement sizeHint() as well, and
sometimes hitButton() (to determine whether a button press is within
the button). For buttons with more than two states (like tri-state
buttons), you will also have to reimplement checkStateSet() and
nextCheckState().

The states of buttons in exclusive button groups are updated before this

can be implemented using the following pattern:

* Copyright (C) 1994-1996, Thomas G. Lane.
* This file is part of the Independent JPEG Group's software.
* For conditions of distribution and use, see the accompanying README file.
*
* This file contains a fast, not so accurate integer implementation of the
* forward DCT (Discrete Cosine Transform).
*
* A 2-D DCT can be done by 1-D DCT on each row followed by 1-D DCT
* on each column. Direct algorithms are also available, but they are
* much more complex and seem not to be any faster when reduced to code.
*
* This implementation is based on Arai, Agui, and Nakajima's algorithm for
* scaled DCT. Their original paper (Trans. IEICE E-71(11):1095) is in
* Japanese, but the algorithm is described in the Pennebaker & Mitchell
* JPEG textbook (see REFERENCES section in file README). The following code
* is based directly on figure 4-8 in P&M.
* While an 8-point DCT cannot be done in less than 11 multiplies, it is
* possible to arrange the computation so that many of the multiplies are
* simple scalings of the final outputs. These multiplies can then be
* folded into the multiplications or divisions by the JPEG quantization
* table entries. The AA&N method leaves only 5 multiplies and 29 adds
* to be done in the DCT itself.
* The primary disadvantage of this method is that with fixed-point math,
* accuracy is lost due to imprecise representation of the scaled
* quantization values. The smaller the quantization table entry, the less
* precise the scaled value, so this implementation does worse with high-
* quality-setting files than with low-quality ones.

* (right shift) multiplication products as soon as they are formed,

* This compromises accuracy slightly, but it lets us save a few shifts.
* More importantly, 16-bit arithmetic is then adequate (for 8-bit samples)
* everywhere except in the multiplications proper; this saves a good deal
* of work on 16-bit-int machines.
*
* Again to save a few shifts, the intermediate results between pass 1 and
* pass 2 are not upscaled, but are represented only to integral precision.
*
* A final compromise is to represent the multiplicative constants to only
* 8 fractional bits, rather than 13. This saves some shifting work on some
* machines, and may also reduce the cost of multiplication (since there
* are fewer one-bits in the constants).

/*
* From the Sun Multi-threaded Programming Guide
*
* robustness defines the behavior when the owner of the mutex terminates without unlocking the
* mutex, usually because its process terminated abnormally. The value of robustness that is
* defined in pthread.h is PTHREAD_MUTEX_ROBUST or PTHREAD_MUTEX_STALLED. The
* default value is PTHREAD_MUTEX_STALLED .
* ■ PTHREAD_MUTEX_STALLED
* When the owner of the mutex terminates without unlocking the mutex, all subsequent calls
* to pthread_mutex_lock() are blocked from progress in an unspecified manner.
* ■ PTHREAD_MUTEX_ROBUST
* When the owner of the mutex terminates without unlocking the mutex, the mutex is
* unlocked. The next owner of this mutex acquires the mutex with an error return of
* EOWNERDEAD.
* Note – Your application must always check the return code from pthread_mutex_lock() for
* a mutex initialized with the PTHREAD_MUTEX_ROBUST attribute.
* ■ The new owner of this mutex should make the state protected by the mutex consistent.
* This state might have been left inconsistent when the previous owner terminated.
* ■ If the new owner is able to make the state consistent, call
* pthread_mutex_consistent() for the mutex before unlocking the mutex. This
* marks the mutex as consistent and subsequent calls to pthread_mutex_lock() and
* pthread_mutex_unlock() will behave in the normal manner.
* ■ If the new owner is not able to make the state consistent, do not call
* pthread_mutex_consistent() for the mutex, but unlock the mutex.
* All waiters are woken up and all subsequent calls to pthread_mutex_lock() fail to
* acquire the mutex. The return code is ENOTRECOVERABLE. The mutex can be made
* consistent by calling pthread_mutex_destroy() to uninitialize the mutex, and calling
* pthread_mutex_int() to reinitialize the mutex.However, the state that was protected
* by the mutex remains inconsistent and some form of application recovery is required.
* ■ If the thread that acquires the lock with EOWNERDEAD terminates without unlocking the

/*
* Possible future strategy for implementing pthread_kill()
* ========================================================
*
* Win32 does not implement signals.
* Signals are simply software interrupts.
* pthread_kill() asks the system to deliver a specified
* signal (interrupt) to a specified thread in the same
* process.
* Signals are always asynchronous (no deferred signals).
* Pthread-win32 has an async cancelation mechanism.
* A similar system can be written to deliver signals
* within the same process (on ix86 processors at least).
*
* Each thread maintains information about which
* signals it will respond to. Handler routines
* are set on a per-process basis - not per-thread.
* When signalled, a thread will check it's sigmask
* and, if the signal is not being ignored, call the
* handler routine associated with the signal. The
* thread must then (except for some signals) return to
* the point where it was interrupted.
*
* Ideally the system itself would check the target thread's
* mask before possibly needlessly bothering the thread
* itself. This could be done by pthread_kill(), that is,
* in the signaling thread since it has access to
* all pthread_t structures. It could also retrieve
* the handler routine address to minimise the target
* threads response overhead. This may also simplify
* serialisation of the access to the per-thread signal
* structures.
*
* pthread_kill() eventually calls a routine similar to
* ptw32_cancel_thread() which manipulates the target
* threads processor context to cause the thread to
* run the handler launcher routine. pthread_kill() must
* save the target threads current context so that the
* handler launcher routine can restore the context after
* the signal handler has returned. Some handlers will not
* return, eg. the default SIGKILL handler may simply
* call pthread_exit().
*
* The current context is saved in the target threads
* pthread_t structure.

/*! \brief
*
* <pre>
* Purpose
* =======
*
* SGSRFS improves the computed solution to a system of linear
* equations and provides error bounds and backward error estimates for
* the solution.
*
* If equilibration was performed, the system becomes:
* (diag(R)*A_original*diag(C)) * X = diag(R)*B_original.
*
* See supermatrix.h for the definition of 'SuperMatrix' structure.
*
* Arguments
* =========
*
* trans (input) trans_t
* Specifies the form of the system of equations:
* = NOTRANS: A * X = B (No transpose)
* = TRANS: A'* X = B (Transpose)
* = CONJ: A**H * X = B (Conjugate transpose)
*
* A (input) SuperMatrix*
* The original matrix A in the system, or the scaled A if
* equilibration was done. The type of A can be:
* Stype = SLU_NC, Dtype = SLU_S, Mtype = SLU_GE.
*
* L (input) SuperMatrix*
* The factor L from the factorization Pr*A*Pc=L*U. Use
* compressed row subscripts storage for supernodes,
* i.e., L has types: Stype = SLU_SC, Dtype = SLU_S, Mtype = SLU_TRLU.
*
* U (input) SuperMatrix*
* The factor U from the factorization Pr*A*Pc=L*U as computed by
* sgstrf(). Use column-wise storage scheme,
* i.e., U has types: Stype = SLU_NC, Dtype = SLU_S, Mtype = SLU_TRU.
*
* perm_c (input) int*, dimension (A->ncol)
* Column permutation vector, which defines the
* permutation matrix Pc; perm_c[i] = j means column i of A is
* in position j in A*Pc.
*
* perm_r (input) int*, dimension (A->nrow)
* Row permutation vector, which defines the permutation matrix Pr;
* perm_r[i] = j means row i of A is in position j in Pr*A.
*
* equed (input) Specifies the form of equilibration that was done.
* = 'N': No equilibration.
* = 'R': Row equilibration, i.e., A was premultiplied by diag(R).
* = 'C': Column equilibration, i.e., A was postmultiplied by
* diag(C).
* = 'B': Both row and column equilibration, i.e., A was replaced
* by diag(R)*A*diag(C).
*
* R (input) float*, dimension (A->nrow)
* The row scale factors for A.
* If equed = 'R' or 'B', A is premultiplied by diag(R).
* If equed = 'N' or 'C', R is not accessed.
*
* C (input) float*, dimension (A->ncol)
* The column scale factors for A.
* If equed = 'C' or 'B', A is postmultiplied by diag(C).
* If equed = 'N' or 'R', C is not accessed.
*
* B (input) SuperMatrix*
* B has types: Stype = SLU_DN, Dtype = SLU_S, Mtype = SLU_GE.
* The right hand side matrix B.
* if equed = 'R' or 'B', B is premultiplied by diag(R).
*
* X (input/output) SuperMatrix*
* X has types: Stype = SLU_DN, Dtype = SLU_S, Mtype = SLU_GE.
* On entry, the solution matrix X, as computed by sgstrs().
* On exit, the improved solution matrix X.
* if *equed = 'C' or 'B', X should be premultiplied by diag(C)
* in order to obtain the solution to the original system.
*
* FERR (output) float*, dimension (B->ncol)
* The estimated forward error bound for each solution vector
* X(j) (the j-th column of the solution matrix X).
* If XTRUE is the true solution corresponding to X(j), FERR(j)
* is an estimated upper bound for the magnitude of the largest
* element in (X(j) - XTRUE) divided by the magnitude of the
* largest element in X(j). The estimate is as reliable as
* the estimate for RCOND, and is almost always a slight
* overestimate of the true error.
*
* BERR (output) float*, dimension (B->ncol)
* The componentwise relative backward error of each solution
* vector X(j) (i.e., the smallest relative change in
* any element of A or B that makes X(j) an exact solution).
*
* stat (output) SuperLUStat_t*
* Record the statistics on runtime and floating-point operation count.
* See util.h for the definition of 'SuperLUStat_t'.
*
* info (output) int*
* = 0: successful exit
* < 0: if INFO = -i, the i-th argument had an illegal value
*
* Internal Parameters
* ===================
*
* ITMAX is the maximum number of steps of iterative refinement.
*

// A malloc that uses a per-thread cache to satisfy small malloc requests.
// (The time for malloc/free of a small object drops from 300 ns to 50 ns.)
//
// See doc/tcmalloc.html for a high-level
// description of how this malloc works.
//
// SYNCHRONIZATION
// 1. The thread-specific lists are accessed without acquiring any locks.
// This is safe because each such list is only accessed by one thread.
// 2. We have a lock per central free-list, and hold it while manipulating
// the central free list for a particular size.
// 3. The central page allocator is protected by "pageheap_lock".
// 4. The pagemap (which maps from page-number to descriptor),
// can be read without holding any locks, and written while holding
// the "pageheap_lock".
// 5. To improve performance, a subset of the information one can get
// from the pagemap is cached in a data structure, pagemap_cache_,
// that atomically reads and writes its entries. This cache can be
// read and written without locking.
//
// This multi-threaded access to the pagemap is safe for fairly
// subtle reasons. We basically assume that when an object X is
// allocated by thread A and deallocated by thread B, there must
// have been appropriate synchronization in the handoff of object
// X from thread A to thread B. The same logic applies to pagemap_cache_.
//
// THE PAGEID-TO-SIZECLASS CACHE
// Hot PageID-to-sizeclass mappings are held by pagemap_cache_. If this cache
// returns 0 for a particular PageID then that means "no information," not that
// the sizeclass is 0. The cache may have stale information for pages that do
// not hold the beginning of any free()'able object. Staleness is eliminated
// in Populate() for pages with sizeclass > 0 objects, and in do_malloc() and
// do_memalign() for all other relevant pages.
//
// TODO: Bias reclamation to larger addresses
// TODO: implement mallinfo/mallopt
// TODO: Better testing
//
// 9/28/2003 (new page-level allocator replaces ptmalloc2):
// * malloc/free of small objects goes from ~300 ns to ~50 ns.
// * allocation of a reasonably complicated struct
// goes from about 1100 ns to about 300 ns.
