Abstract Class -> ASSERT failure in QWidget: "Widgets must be created in the GUI thread."

[Leocor]

Hi to everyone!

I'm developing with Qt 5.1 (VS2012 - 32bit).

I have a strange problem. I use a abstract class (iLog) and derived classes (e.g. ConsoleLog -> to log into stdout/stderr). One (PopupLog) class creates QMessageBoxes with errors ..

When I use:
Popuplog *p = new Popuplog();
p->error("blah blah");//this is a virtual function -> virtual void iLog::error(QString&) = 0;
It works fine!!

When I use:
iLog *p = new Popuplog();
p->error("blah blah");
My software crashes with:
ASSERT failure in QWidget: "Widgets must be created in the GUI thread.", file kernel\qwidget.cpp, line 1111
QObject::killTimers: timers cannot be stopped from another thread

To be honest, I have no clue why!
Do you have any advice or a idea??

SRY I made a mistake could the ADMIN remove this topic!
