# This example demonstrates how to control section selection.
|
|
# It allows only one of the four optional section to be
|
|
# selected at any given time.
|
|
#
|
|
# Please note that the initial value will not be what you expect
|
|
# it to be if you are are using InstType because InstType is taken
|
|
# into consideration after the .onInit, where the initial state is
|
|
# set, executes.
|
|
# To use this code with InstType you will either have to specify
|
|
# you first InstType to match the initial value you set in .onInit
|
|
# (only StrCpy $1 ${sec1} is important in this case because the
|
|
# other set the section and that will be done by InstType), or set
|
|
# the initial section selection from .onSelChange when it is called
|
|
# for the first time.
