This method is called by the
Agentry
Client when
the focus is set to the External Field - ActiveX Control detail
screen field due to one of the following events:
- Auto
Focus: The parent screen has just been displayed, that screen’s Focus
Field attribute is defined as Auto, and the External Field -
ActiveX Control detail screen field is in the position to receive
the focus.
- Initial Focus: The parent screen has just been displayed
and that screen’s Focus Field attribute is defined to set
the focus explicitly to the External Field - ActiveX Control detail
screen field.
- Auto Change Focus: The previous detail screen field is
defined to automatically change focus to the next field, the External
Field - ActiveX Control field is the next field, and the user has
just entered a value in the previous field.
- OS Focus: The OS has sent a message that the External
Field - ActiveX Control should receive the focus. This can occur
when the user tabs to the field, selects the field’s hot key, and
other similar situations.
The value of the type
parameter to this method indicates which of the above is the reason
for the External Field - ActiveX Control to have received the focus
should it be necessary to perform different processing based on
the focus event.
