[Interest] is there any way to avoid compression of event
Hi there, Qt does this mouse move event compression, I can imagine it is good but in one of my application where user is doing some kind of drawing with mouse we dont want this compression of mouse move event take place, is there any way I can avoid this? I see QCoreApplication::compressEvent() is virtual function can I use this? if yes can any one please guide how? regards, Harris ___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
Re: [Interest] is there any way to avoid compression of event
If I subclass coreapplication and reimplement compressEvent, how do I use this class in my GUI application which already has QApplication object ? any help will be appreciated.

Re: [Interest] is there any way to avoid compression of event
You mean I should use an object of myCoreApplication rathe QCoreApplication, But documentation says for GUI application one will have to use QApplication and for non gui Qcoreapplication. So if i use subclass of qcoreapplication wont this create any problem in my GUI. Documentation further says coreapplication class handles eventloop for console application and qapplication class for GUI aplication.

Re: [Interest] is there any way to avoid compression of event
I rechecked it, it is not public function and not mentioned in documentation, I found it in .h file it is protected member in QApplication.h but not Virtual :( though I see it is virtual in qcoreapplication.h On Tue, Mar 20, 2012 at 4:27 PM, Efan... wrote: > that is the problem it is not virtual in QApplication it is virtual in > QCoreApplicatoin > > > On Tue, Mar 20, 2012 at 4:24 PM, Thiago Macieira < > thiago.macie...@intel.com> wrote: > >> On terça-feira, 20 de março de 2012 16.04.49, Efan... wrote: >> > You mean I should use an object of myCoreApplication rathe >> QCoreApplication, >> > >> > But documentation says for GUI application one will have to use >> > QApplication and for non gui Qcoreapplication. >> > So if i use subclass of qcoreapplication wont this create any problem >> in my >> > GUI. >> > Documentation further says coreapplication class handles eventloop for >> > console application and qapplication class for GUI aplication. >> > >> > Please help >> >> You shouldn't derive from QCoreApplication.
