Question

下面的代码工作正常，只是我想在创建卷展栏之前动态更改标签文本，而不是之后。我正在尝试将变量（rolloutlabel）作为字符串传递给卷展栏，只有我不能通过使用按钮更新它而不必编写代码。如果取消注释第6行，我得到的（无用的）错误是“语法错误：at =，期望名称”

rolloutlabel = "label"
rollout rolloutDialog "Rollout" width:100 height:50
(
    label alabel "" pos:[10,10] width:90 height:16
    button updateBTN "Update label" pos:[10,25] width:80 height:16
    -- alabel.text = rolloutlabel as string
    -- this just gets a syntax error if i leave it here uncommented
    on updateBTN pressed do
    (
        alabel.text = rolloutlabel
    )
)
createDialog rolloutDialog

知道我哪里出错了？

看一下rollout open子句：

rolloutlabel = "label"
rollout rolloutDialog "Rollout" width:100 height:50
(
    label alabel "" pos:[10,10] width:90 height:16
    button updateBTN "Update label" pos:[10,25] width:80 height:16
    -- alabel.text = rolloutlabel as string
    -- this just gets a syntax error if i leave it here uncommented

    on rolloutDialog open do
    (
        alabel.text = rolloutlabel
    )


    on updateBTN pressed do
    (
        alabel.text = rolloutlabel
    )
)
createDialog rolloutDialog

你可以保留相同的脚本，但是在alabel之后你可以简单地编写rolloutlabel而不是空的双引号。脚本将是这样的：

rolloutlabel = "label"
rollout rolloutDialog "Rollout" width:100 height:50
(
    label alabel rolloutlabel pos:[10,10] width:90 height:16
    button updateBTN "Update label" pos:[10,25] width:80 height:16
    --alabel.text = (rolloutlabel as string)
    -- this just gets a syntax error if i leave it here uncommented
    on updateBTN pressed do
    (
        alabel.text = rolloutlabel
    )
)
createDialog rolloutDialog
