QListView problem continued
Message 1 in thread
hi
this is really bugging me . i read that manuals and it says qApp is a global
pointer to the QApplication that starts the exec (the event loop)
i used qt3 designer to make a dialog boxed application form.ui.h which creates
a class form
i am able to run the application perfectly as such but now solving the problem
of the qlistview if i add qApp->processEvents in my *Form* functions it says
qApp is undeclared ... what am i missing now ???
i know i am doing some careless mistake somewhere just please point it out :0)
actually i am not sure which ways the the IDE -> QT Designer works as i can
not see the widget declaration with in the main. but found in my form class.
but still qApp seems to be a hinder.
regards
Rohit

Do you have this:
#include <qapplication.h>
in the file where you have the qApp->processEvents() ?

what the heck is qa?????? As I wrote as and as it is stated in the documents,
the variable is named qApp and not qa ! If this was just a typo in your mail,
have you included qapplication.h in the file where you call processEvents()?
