[Qt-interest] Crashing without debug mode- No crashing with gdb debugger

[Sujan Dasmahapatra]

Dear All

I am facing some problem in implementing a QScrollArea. I  subclassed it
and created a buttin on this as below.

 

CScrollArea::CScrollArea() {

printbutton = new QPushButton("Save As Image",this);

printbutton->setGeometry(actual_page_width + coordx-100,coordy,100,25);

connect(printbutton,SIGNAL(clicked()),this,SLOT(gotoprinter()));

}

 

the problem is that when I am trying show this scrollarea through menu
click its crashing. and crashing at the first line 

printbutton = new QPushButton("Save As Image",this);

 

but when I am debugging this through gdb debugger then its running fine
and at the end i can see the scroll are with button.

 

Why is happening like this. Any idea from anyone would be highly
appreciate.

Also when I try to set a window title like 

setWindowTitle("My Page");

its again crashing.

Thanks in advance for any help. sujan

 

 

Kind Regards,
