Hello Dmitry,
at first, i need a place where i can store my signals. The second is a
method which is called each update. This method have to check the
flags of the signals and emit the signals which are set to true.
Therefore i need an access to link my method to the loop mechanism. If
"notify" is a method which is called each update, then this is a way
to hook my method to that mexhanism (by overload notify).
Thanks, Sven

Sorry, I didn't clearly understand what do you want to implement,
but if you want to have some control on event propagation to
you application besides the contructor you may want to
reimplement WApplication::notify() method.
But as I understand, all that you want is to implement
pagination?

Hallo Dmitry,
thanks for your suggestion. Do you also know how i can connect a
update method with the loop mechanism from wt.The emit call has to
be only on one place of the mainloop. Each nextPage-Call only set
the update Flag of a signal. The check method which is called each
update check the Flag and emit the signals. Any idea, where i can
implement or override such a method?
Thanks, Sven

You may do it by implementing the widget (container) with a slot
inside, which will replace the current widget ("page") with next
widget
("page") in some place on the page where you want.
class MyWidget : public Wt::WContainerWidget {
// code
private:
Wt::WContainerWidget* page_;
Wt::WContainerWidget* paginator_; // emits the signal, e.g.,
"internalPathChanged", or clicked....
void nextPage(); // slot. Loads new page to the page_
// code
};

Thanks for your response. I was wrong by using The internal
EventSignal. Are there possibilities to register my Signals on the
existing signal handler of WApplication or WContainerWidget? I want
to handle my own Signals on à Central place. Currently i have a pa
gehandler which inherits from WApplication an Pages which inherit
from WContainerWidget. When i want to load the next page, i want t
o call a method from my pagehandler "nextpage()". To avoid a self
destruction by a call from a page i want to set the updateflag of
The Signal to true. When now The Signal handler ask for this flag,
the signal will be called by call emit.
Any idea where to integrate ore which handler i can use?
Many thanks in advance,
Sven
