Maxscript：如何访问稍后在卷展栏中其他组中定义的 UI 控件（脚本插件）
我有一个 simpleObject 脚本插件，在其中定义参数块及其关联的卷展栏：
rollout mainParamsRollout "Main Properties"
(
group "Group1"
(
dropdownlist ddl1 "ddl1" items:#("A", "B") height:4
on ddl1 selected i do
(
ddl2.enabled = false
)
)
group "Group2"
(
dropdownlist ddl2 "ddl2" items:#("C", "D") height:4
)
)
当我在 ddl1 上发生特定选择后尝试禁用 ddl2 时，maxscript 会抛出异常，指出 ddl2 未定义。
我知道可以通过 mainParamsRollout.controls[5] 访问 ddl2，但我想知道是否有更好的方法。我尝试在脚本化插件的顶部定义一个局部变量：
local ddl2
以使其在任何地方都可用，但这似乎也不起作用。有什么想法吗？ 谢谢
I have a simpleObject scripted plug-in where I define a parameters block and its associated rollout:
rollout mainParamsRollout "Main Properties"
(
group "Group1"
(
dropdownlist ddl1 "ddl1" items:#("A", "B") height:4
on ddl1 selected i do
(
ddl2.enabled = false
)
)
group "Group2"
(
dropdownlist ddl2 "ddl2" items:#("C", "D") height:4
)
)
When I try to make ddl2 disabled after a certain selection happens on ddl1, maxscript throws an exception saying that ddl2 is undefined.
I know it is possible to access ddl2 though mainParamsRollout.controls[5] but I am wondering if there is a better way. I have tried defining a local variable at the top of the scripted plugin as:
local ddl2
to make it available anywhere but this does not seem to work either. Any ideas?
Thanks

在
ddl1的事件处理程序中调用ddl2之前，必须声明它。您可以这样订购您的代码：ddl2must be declared before calling it inddl1's event handler. You can order your code as such:或者只是在控件之前添加卷展栏，例如
然后在哪里调用控件并不重要。

Or just add the rollout before the control like
Then it doesn't matter where you call the control.
