\class TQApplication ntqapplication.h
\brief The TQApplication class manages the GUI application's control
flow and main settings.
\ingroup application
\mainclass
It contains the main event loop, where all events from the window
system and other sources are processed and dispatched. It also
handles the application's initialization and finalization, and
provides session management. It also handles most system-wide and
application-wide settings.
For any GUI application that uses TQt, there is precisely one
TQApplication object, no matter whether the application has 0, 1, 2
or more windows at any time.
The TQApplication object is accessible through the global pointer \c
tqApp. Its main areas of responsibility are:
\list
\i It initializes the application with the user's desktop settings
such as palette(), font() and doubleClickInterval(). It keeps track
of these properties in case the user changes the desktop globally, for
example through some kind of control panel.
\i It performs event handling, meaning that it receives events
from the underlying window system and dispatches them to the relevant
widgets. By using sendEvent() and postEvent() you can send your own
events to widgets.
\i It parses common command line arguments and sets its internal
state accordingly. See the \link TQApplication::TQApplication()
constructor documentation\endlink below for more details about this.
\i It defines the application's look and feel, which is
encapsulated in a TQStyle object. This can be changed at runtime
with setStyle().
\i It specifies how the application is to allocate colors.
See setColorSpec() for details.
\i It provides localization of strings that are visible to the user
via translate().
\i It provides some magical objects like the desktop() and the
clipboard().
\i It knows about the application's windows. You can ask which
widget is at a certain position using widgetAt(), get a list of
topLevelWidgets() and closeAllWindows(), etc.
\i It manages the application's mouse cursor handling,
see setOverrideCursor() and setGlobalMouseTracking().
\i On the X window system, it provides functions to flush and sync
the communication stream, see flushX() and syncX().
\i It provides support for sophisticated \link
session.html session management \endlink. This makes it possible
for applications to terminate gracefully when the user logs out, to
cancel a shutdown process if termination isn't possible and even to
preserve the entire application's state for a future session. See
isSessionRestored(), sessionId() and commitData() and saveState()
for details.
\endlist
The <a href="simple-application.html">Application walk-through
example</a> contains a typical complete main() that does the usual
things with TQApplication.
Since the TQApplication object does so much initialization, it
<b>must</b> be created before any other objects related to the user
interface are created.
Since it also deals with common command line arguments, it is
usually a good idea to create it \e before any interpretation or
modification of \c argv is done in the application itself. (Note
also that for X11, setMainWidget() may change the main widget
according to the \c -geometry option. To preserve this
functionality, you must set your defaults before setMainWidget() and
any overrides after.)

\relates TQApplication
Adds a global routine that will be called from the TQApplication
destructor. This function is normally used to add cleanup routines
for program-wide functionality.
The function given by \a p should take no arguments and return
nothing, like this:
\code
static int *global_ptr = 0;
static void cleanup_ptr()
{
delete [] global_ptr;
global_ptr = 0;
}
void init_ptr()
{
global_ptr = new int[100]; // allocate data
tqAddPostRoutine( cleanup_ptr ); // delete later
}
\endcode
Note that for an application- or module-wide cleanup,
tqAddPostRoutine() is often not suitable. People have a tendency to
make such modules dynamically loaded, and then unload those modules
long before the TQApplication destructor is called, for example.
For modules and libraries, using a reference-counted initialization
manager or TQt' parent-child delete mechanism may be better. Here is
an example of a private class which uses the parent-child mechanism
to call a cleanup function at the right time:
\code
class MyPrivateInitStuff: public TQObject {
private:
MyPrivateInitStuff( TQObject * parent ): TQObject( parent) {
// initialization goes here
}
MyPrivateInitStuff * p;
public:
static MyPrivateInitStuff * initStuff( TQObject * parent ) {
if ( !p )
p = new MyPrivateInitStuff( parent );
return p;
}
~MyPrivateInitStuff() {
// cleanup (the "post routine") goes here
}
}
\endcode
By selecting the right parent widget/object, this can often be made
to clean up the module's data at the exact right moment.

/*!
Initializes the window system and constructs an application object
with \a argc command line arguments in \a argv.
The global \c tqApp pointer refers to this application object. Only
one application object should be created.
This application object must be constructed before any \link
TQPaintDevice paint devices\endlink (including widgets, pixmaps, bitmaps
etc.).
Note that \a argc and \a argv might be changed. TQt removes command
line arguments that it recognizes. The modified \a argc and \a argv
can also be accessed later with \c tqApp->argc() and \c tqApp->argv().
The documentation for argv() contains a detailed description of how
to process command line arguments.
TQt debugging options (not available if TQt was compiled with the
TQT_NO_DEBUG flag defined):
\list
\i -nograb, tells TQt that it must never grab the mouse or the keyboard.
\i -dograb (only under X11), running under a debugger can cause
an implicit -nograb, use -dograb to override.
\i -sync (only under X11), switches to synchronous mode for
debugging.
\endlist
See \link debug.html Debugging Techniques \endlink for a more
detailed explanation.
All TQt programs automatically support the following command line options:
\list
\i -reverse causes text to be formatted for right-to-left languages
rather than in the usual left-to-right direction.
\i -style= \e style, sets the application GUI style. Possible values
are \c motif, \c windows, and \c platinum. If you compiled TQt
with additional styles or have additional styles as plugins these
will be available to the \c -style command line option.
\i -style \e style, is the same as listed above.
\i -session= \e session, restores the application from an earlier
\link session.html session \endlink.
\i -session \e session, is the same as listed above.
\i -widgetcount, prints debug message at the end about number of widgets left
undestroyed and maximum number of widgets existed at the same time
\endlist
The X11 version of TQt also supports some traditional X11
command line options:
\list
\i -display \e display, sets the X display (default is $DISPLAY).
\i -geometry \e geometry, sets the client geometry of the
\link setMainWidget() main widget\endlink.
\i -fn or \c -font \e font, defines the application font. The
font should be specified using an X logical font description.
\i -bg or \c -background \e color, sets the default background color
and an application palette (light and dark shades are calculated).
\i -fg or \c -foreground \e color, sets the default foreground color.
\i -btn or \c -button \e color, sets the default button color.
\i -name \e name, sets the application name.
\i -title \e title, sets the application title (caption).
\i -visual \c TrueColor, forces the application to use a TrueColor visual
on an 8-bit display.
\i -ncols \e count, limits the number of colors allocated in the
color cube on an 8-bit display, if the application is using the
\c TQApplication::ManyColor color specification. If \e count is
216 then a 6x6x6 color cube is used (i.e. 6 levels of red, 6 of green,
and 6 of blue); for other values, a cube
approximately proportional to a 2x3x1 cube is used.
\i -cmap, causes the application to install a private color map
on an 8-bit display.

Returns the command line argument vector.

A TQApplication object is constructed by passing \e argc and \e
argv from the \c main() function. Some of the arguments may be
recognized as TQt options and removed from the argument vector. For
example, the X11 version of TQt knows about \c -display, \c -font
and a few more options.
Example:
\code
// showargs.cpp - displays program arguments in a list box
#include <ntqapplication.h>
#include <ntqlistbox.h>
int main( int argc, char **argv )
{
TQApplication a( argc, argv );

b.insertItem( a.argv()[i] ); // a.argv()[i] == argv[i]
b.show();
return a.exec();
}
\endcode
If you run \c{showargs -display unix:0 -font 9x15bold hello world}
under X11, the list box contains the three strings "showargs",
"hello" and "world".
TQt provides a global pointer, \c tqApp, that points to the

Sets the color specification for the application to \a spec.
The color specification controls how the application allocates colors
when run on a display with a limited amount of colors, e.g. 8 bit / 256
color displays.
The color specification must be set before you create the TQApplication
object.
The options are:
\list
\i TQApplication::NormalColor.
This is the default color allocation strategy. Use this option if
your application uses buttons, menus, texts and pixmaps with few
colors. With this option, the application uses system global
colors. This works fine for most applications under X11, but on
Windows machines it may cause dithering of non-standard colors.
\i TQApplication::CustomColor.
Use this option if your application needs a small number of custom
colors. On X11, this option is the same as NormalColor. On Windows, TQt
creates a Windows palette, and allocates colors to it on demand.
\i TQApplication::ManyColor.
Use this option if your application is very color hungry
(e.g. it requires thousands of colors).
Under X11 the effect is:
\list
\i For 256-color displays which have at best a 256 color true color
visual, the default visual is used, and colors are allocated
from a color cube. The color cube is the 6x6x6 (216 color) "Web
palette"<sup>*</sup>, but the number of colors can be changed
by the \e -ncols option. The user can force the application to
use the true color visual with the \link
TQApplication::TQApplication() -visual \endlink option.
\i For 256-color displays which have a true color visual with more
than 256 colors, use that visual. Silicon Graphics X servers
have this feature, for example. They provide an 8 bit visual
by default but can deliver true color when asked.
\endlist
On Windows, TQt creates a Windows palette, and fills it with a color cube.
\endlist
Be aware that the CustomColor and ManyColor choices may lead to colormap
flashing: The foreground application gets (most) of the available
colors, while the background windows will look less attractive.
Example:
\code
int main( int argc, char **argv )
{
TQApplication::setColorSpec( TQApplication::ManyColor );
TQApplication a( argc, argv );
...
}
\endcode
TQColor provides more functionality for controlling color allocation and
freeing up certain colors. See TQColor::enterAllocContext() for more
information.
To check what mode you end up with, call TQColor::numBitPlanes() once
the TQApplication object exists. A value greater than 8 (typically
16, 24 or 32) means true color.
<sup>*</sup> The color cube used by TQt has 216 colors whose red,
green, and blue components always have one of the following values:
0x00, 0x33, 0x66, 0x99, 0xCC, or 0xFF.

Sends event \a e to \a receiver: \a {receiver}->event(\a e).

For certain types of events (e.g. mouse and key events),

the top-level object if the receiver is not interested in the event
(i.e., it returns FALSE).
There are five different ways that events can be processed;
reimplementing this virtual function is just one of them. All five
approaches are listed below:
\list 1
\i Reimplementing this function. This is very powerful, providing
complete control; but only one subclass can be tqApp.
\i Installing an event filter on tqApp. Such an event filter is able
to process all events for all widgets, so it's just as powerful as
reimplementing notify(); furthermore, it's possible to have more
than one application-global event filter. Global event filters even
see mouse events for \link TQWidget::isEnabled() disabled
widgets, \endlink and if \link setGlobalMouseTracking() global mouse
tracking \endlink is enabled, as well as mouse move events for all
widgets.
\i Reimplementing TQObject::event() (as TQWidget does). If you do
this you get Tab key presses, and you get to see the events before
any widget-specific event filters.
\i Installing an event filter on the object. Such an event filter
gets all the events except Tab and Shift-Tab key presses.
\i Reimplementing paintEvent(), mousePressEvent() and so
on. This is the commonest, easiest and least powerful way.

\class TQSessionManager ntqsessionmanager.h
\brief The TQSessionManager class provides access to the session manager.
\ingroup application
\ingroup environment
The session manager is responsible for session management, most
importantly for interruption and resumption. A "session" is a kind
of record of the state of the system, e.g. which applications were
run at start up and which applications are currently running. The
session manager is used to save the session, e.g. when the machine
is shut down; and to restore a session, e.g. when the machine is
started up. Use TQSettings to save and restore an individual
application's settings, e.g. window positions, recently used files,
etc.
TQSessionManager provides an interface between the application and
the session manager so that the program can work well with the
session manager. In TQt, session management requests for action
are handled by the two virtual functions TQApplication::commitData()
and TQApplication::saveState(). Both provide a reference to
a session manager object as argument, to allow the application
to communicate with the session manager.
During a session management action (i.e. within commitData() and
saveState()), no user interaction is possible \e unless the
application got explicit permission from the session manager. You
ask for permission by calling allowsInteraction() or, if it's really
urgent, allowsErrorInteraction(). TQt does not enforce this, but the
session manager may.
You can try to abort the shutdown process by calling cancel(). The
default commitData() function does this if some top-level window
rejected its closeEvent().
For sophisticated session managers provided on Unix/X11, TQSessionManager
offers further possibilites to fine-tune an application's session
management behavior: setRestartCommand(), setDiscardCommand(),
setRestartHint(), setProperty(), requestPhase2(). See the respective
function descriptions for further details.
*/
/*! \enum TQSessionManager::RestartHint
This enum type defines the circumstances under which this
application wants to be restarted by the session manager. The
current values are
\value RestartIfRunning if the application is still running when
the session is shut down, it wants to be restarted at the start of
the next session.
\value RestartAnyway the application wants to be started at the
start of the next session, no matter what. (This is useful for
utilities that run just after startup and then quit.)
\value RestartImmediately the application wants to be started
immediately whenever it is not running.
\value RestartNever the application does not want to be restarted
automatically.
The default hint is \c RestartIfRunning.

/*!
\fn void* TQSessionManager::handle() const
X11 only: returns a handle to the current \c SmcConnection.
*/
/*!
\fn bool TQSessionManager::allowsInteraction()
Asks the session manager for permission to interact with the
user. Returns TRUE if interaction is permitted; otherwise
returns FALSE.
The rationale behind this mechanism is to make it possible to
synchronize user interaction during a shutdown. Advanced session
managers may ask all applications simultaneously to commit their
data, resulting in a much faster shutdown.
When the interaction is completed we strongly recommend releasing the
user interaction semaphore with a call to release(). This way, other
applications may get the chance to interact with the user while your
application is still busy saving data. (The semaphore is implicitly
released when the application exits.)
If the user decides to cancel the shutdown process during the
interaction phase, you must tell the session manager that this has
happened by calling cancel().
Here's an example of how an application's TQApplication::commitData()
might be implemented:
\code
void MyApplication::commitData( TQSessionManager& sm ) {
if ( sm.allowsInteraction() ) {
switch ( TQMessageBox::warning(
yourMainWindow,
tr("Application Name"),
tr("Save changes to document Foo?"),
tr("&Yes"),
tr("&No"),
tr("Cancel"),
0, 2) ) {
case 0: // yes
sm.release();
// save document here; if saving fails, call sm.cancel()
break;
case 1: // continue without saving
break;
default: // cancel
sm.cancel();
break;
}
} else {
// we did not get permission to interact, then
// do something reasonable instead.
}
}
\endcode
If an error occurred within the application while saving its data,
you may want to try allowsErrorInteraction() instead.
\sa TQApplication::commitData(), release(), cancel()
*/
/*!
\fn bool TQSessionManager::allowsErrorInteraction()
This is similar to allowsInteraction(), but also tells the session
manager that an error occurred. Session managers may give error
interaction request higher priority, which means that it is more likely
that an error interaction is permitted. However, you are still not
guaranteed that the session manager will allow interaction.
\sa allowsInteraction(), release(), cancel()
*/
/*!
\fn void TQSessionManager::release()
Releases the session manager's interaction semaphore after an
interaction phase.
\sa allowsInteraction(), allowsErrorInteraction()

/*!
\fn void TQSessionManager::cancel()

should not call this function without first asking the user.
\sa allowsInteraction(), allowsErrorInteraction()
*/
/*!
\fn void TQSessionManager::setRestartHint( RestartHint hint )
Sets the application's restart hint to \a hint. On application
startup the hint is set to \c RestartIfRunning.
Note that these flags are only hints, a session manager may or may
not respect them.
We recommend setting the restart hint in TQApplication::saveState()
because most session managers perform a checkpoint shortly after an
application's startup.

/*!
\fn TQSessionManager::RestartHint TQSessionManager::restartHint() const
Returns the application's current restart hint. The default is

/*!
\fn void TQSessionManager::setRestartCommand( const TQStringList& command )
If the session manager is capable of restoring sessions it will
execute \a command in order to restore the application. The command
defaults to
\code
appname -session id
\endcode
The \c -session option is mandatory; otherwise TQApplication cannot
tell whether it has been restored or what the current session
identifier is. See TQApplication::isSessionRestored() and
TQApplication::sessionId() for details.
If your application is very simple, it may be possible to store the
entire application state in additional command line options. This
is usually a very bad idea because command lines are often limited
to a few hundred bytes. Instead, use TQSettings, or temporary files
or a database for this purpose. By marking the data with the unique
sessionId(), you will be able to restore the application in a future
session.

/*!
\fn TQStringList TQSessionManager::restartCommand() const
Returns the currently set restart command.
Note that if you want to iterate over the list, you should

Returns the currently set discard command.

iterate over a copy, e.g.
\code
TQStringList list = mySession.discardCommand();
TQStringList::Iterator it = list.begin();
while( it != list.end() ) {
myProcessing( *it );
++it;

/*!
\fn void TQSessionManager::requestPhase2()
Requests a second session management phase for the application. The
application may then return immediately from the
TQApplication::commitData() or TQApplication::saveState() function,
and they will be called again once most or all other applications have
finished their session management.
The two phases are useful for applications such as the X11 window manager
that need to store information about another application's windows
and therefore have to wait until these applications have completed their
respective session management tasks.
Note that if another application has requested a second phase it
may get called before, simultaneously with, or after your
application's second phase.

/*!
\fn int TQApplication::horizontalAlignment( int align )
Strips out vertical alignment flags and transforms an
alignment \a align of AlignAuto into AlignLeft or
AlignRight according to the language used. The other horizontal
alignment flags are left untouched.
