Implement "gray" when uicontrol radiobutton/checkbox are disabled (bug #57128) * BaseControl.cc (updatePalette): Call setColor() with additional argument of "QPalette::Active" and again with "QPalette::Inactive" so that colors are set only for specific roles. * CheckBoxControl.h (CheckBoxControl): Declare new private member function update(). * CheckBoxControl.cc (CheckBoxControl): Check for "Enable" property value of "inactive" and call setCheckable (false) if found. * CheckBoxControl.cc (update): New function to intercept and handle change to "Enable" property before forwarding to BaseControl. * RadioButtonControl.cc (RadioButtonControl): Check for "Enable" property value of "inactive" and call setCheckable (false) if found. * RadioButtonControl.cc (update): New function to intercept and handle change to "Enable" property before forwarding to BaseControl.
