[paragui-users] Callback Object for Radiobuttons

[Evil Azrael]

Hi!

I am currently try to install an callback function for an RadioButton,
but it crashs the programm at the end of the calling function ( the
constructor of the window). The Crash Message is
"The value of ESP was not properly saved across a function call.
This is usually a result of calling a function declared with one
calling convention with a function pointer declared with a differient
calling convention"

Can i do it like this, or do i have to derive a new control for this
purpose?

size1 = new PG_RadioButton(this,RAD_SIZE1 ,PG_Rect(175,50,100,25),"klein");
size1->SetEventObject(MSG_BUTTONCLICK,this, (MSG_CALLBACK_OBJ) 
&Schritt1::aenderung,NULL);

Thanx in advance for any answer and especially for any help :)
