PHAB Widget white Border

PHAB Widget white Border
After pressing widget button then a white colour border is highlighted after release button while colour border is
cleared.

Please suggest us how to remove this highlighted border. I do not require this highlighted border after pressing button.
code:
PtSetArg( &arg[0], Pt_ARG_FILL_COLOR, QMMI_COLOR_DBLUE1, 0);
PtSetArg( &arg[1], Pt_ARG_TOP_BORDER_COLOR, QMMI_COLOR_BORDER_BUT_TOP, 0);
PtSetArg( &arg[2], Pt_ARG_BOT_BORDER_COLOR, QMMI_COLOR_BORDER_BUT_BOT, 0);
PtSetArg( &arg[3], Pt_ARG_COLOR, QMMI_COLOR_TEXT_NORMAL, 0);
PtSetArg( &arg[4], Pt_ARG_FLAGS, Pt_SELECTABLE,Pt_SELECTABLE|Pt_TOGGLE|Pt_SET);
PtSetArg( &arg[5], Pt_ARG_TEXT_STRING,“A c k” ,0);

Button Issue

Please see the attached screen shot for reference.

There’s a property for widgets, I think it’s “Get’s Focus”. If a widget has focus and you press Enter, it’s like you clicked on it with a mouse. The border indicates that a widget has focus. If you remove the “Get’s Focus” property I think you will not see the border anymore.
