This class is used when writing Qt applications. It should be one of the first things done in the main function of your application. Use the Async::QtApplication class in place of the QApplication class.

In the application you do not have to use the Async classes for timers and file descriptor watches. It is perfecly legal to use the Qt variants (QTimer and QSocketNotifier). You can mix them as much as you like.

#include <AsyncQtApplication.h>
#include <QPushButton>
 
using namespace Async;
 
int main(int argc, char **argv)
{
  QtApplication app(argc, argv);
  QPushButton hello("Hello, Async::QtApplication", 0);
  QObject::connect(&hello, SIGNAL(clicked()), &app, SLOT(quit()));
  hello.show();
  app.exec();
}

Examples

AsyncQtApplication_demo.cpp.

Constructor & Destructor Documentation

QtApplication()

Async::QtApplication::QtApplication	(	int &	argc,
		char **	argv )

Constructor.

The two arguments typically are the arguments given to the main function.

Parameters

argc	The number of command line arguments + 1
argv	An array containing the commandline arguments

~QtApplication()

virtual Async::QtApplication::~QtApplication ( void )

virtual

Destructor.

Member Function Documentation

exec()

void Async::QtApplication::exec ( void )

virtual

Execute the application main loop.

When this member function is called the application core will enter the main loop. It will not exit from this loop until the Async::Application::quit method is called.

Implements Async::Application.

Examples

AsyncQtApplication_demo.cpp.

quit

void Async::QtApplication::quit ( void )

slot

Exit the application main loop.

This function should be called to exit the application core main loop.
