[Qt-interest] Adding custom widget plugins error/problem

[Malyushytsky, Alex]

It looks like compiler complains on  WorldTimeClock::WorldTimeClock(QWidget*)

You need constructor taking QWidget* of WorldTimeClock  class as a parameter not QObject* of WorldTimeClockPlugin, which is fine.

Something like this:

WorldTimeClock::WorldTimeClock (QWidget *parent)
: QWidget(parent)
{
......
}

You either missing include , in this case find which file has this definition ( even if it was generated ) and add appropriate include.

Or you forgot to declare / define this constructor in your code.


Regards,
   Alex

Hi,

the custom widget constructor is specified here:

WorldTimeClockPlugin::WorldTimeClockPlugin(QObject *parent)
: QObject(parent)
{
initialized = false;
}


Please, where should I initialize the constructor? I'm designing
(importing custom widgets) via designer in QtCreator. That is making
ui_*.h file - that I can not modify.

thnks,
Miro
