How to set dynamic push button as no frame?

[Charles Woo]

All,

Recently, I faced a problem in setting no frame for a push button which I
dynamically create it.

The code is as follows:
// code starts here
ControlPtr p;

p = CtlNewControl((VoidPtr) &frm, PushButId, pushButtonCtl, "abc", 5, 127, 28,

32, stdFont, 1, true);
p->attr.frame = 0x00;
CtlDrawControl(p);

// code ends here

I have proofed that it works for button, but not in push button. Why ?

Thanks for your help in advanced.
