Focus rule tab of Screen Set control
The property dialog of the Screen Set Control in the background of
the screen form is displayed, and set up the property on the Focus rule
tab. On this tab, it is possible to specify whether to enable or disable
the common focus movement rule and the continuous input function
for controls with input.
Listed below are how to determine the way the focus is to move
basically according to the common focus movement rule. In “Control
layout” below, each circled number (<1>,<2>,<3>) indicates an
example location where the corresponding one of the listed rules is
applied when one of the indicated cursor keys is pressed.
<1> When a cursor key is pressed, the focus will move to a control
having a focusing index number obtained by adding the
corresponding cursor key direction value (focus index
increment/decrement) set up as the Common focus movement
rule to the focusing index number of the control currently having
the focus.
<2> If the focusing index number obtained above is not within the
current screen, a check is made to see whether there is a row or
column before or after the control with input of interest. If a row
or column turns out to exist, the focus will move to the target
control on the row or column.
<3> If the above step does not find a target column within the current
screen, the focus will move to the next subscreen or, if there is no
“next” subscreen, the focus will move to the first or last control
with input on the current screen.
