WTimer works great in the gui, just like QTimer. Just connect the connect
the timer "timeout( WMouseEvent )" signal to an appropriate slot in your gui
class and it will be called when the timer times out.
Example:
class MyGuiClass, public WContainerWidget;
{
public:
MyGuiClass( WContainerWidget* parent );
public slots:
timerslot( WMouseEvent wme );
};
MyGuiClass::MyGuiClass( WObject* parent ) : WContainerWidget( parent )
{
// Full config
WTimer* t = new WTimer( this );
t->setInterval( 2000 );
t->timeout().connect(SLOT( this, MyGuiClass::timerslot ));
t->start();
// Or convenience method
WTimer::singleShot( 2000, SLOT( this, MyGuiClass::timerslot ));
// They both do the same thing, just one is more configurable
}
MyGuiClass:: timerslot( WMouseEvent wme )
{
// executes 2 seconds (2000 ms) after t->start()
}
Fun fun fun,
Mike
