Installation 无法理解${NSD_GetState}$复选框为什么不起作用

有人能向我解释一下${NSD_GetState}$复选框为什么不起作用吗？ 我花了大约4个小时试图找出问题所在。我尝试了不同的变体，但在这个脚本中它们不起作用

实际上，这是我第一次尝试制作nsis安装程序，所以我甚至不知道应该在哪里查找错误，或者我只是不理解这种语言的逻辑

来自俄罗斯的爱：） 对不起，我的英语不好

在您的示例中有太多不相关的代码，以至于有点难以理解您真正想要做什么

如果要检索另一页上复选框的状态，则必须保存该状态，因为离开该页时复选框控件将被销毁

!include nsDialogs.nsh

Var hwndCheckbox
Var CheckboxState
Page Custom myPageWithCombobox myPageWithComboboxLeaveCallback
Page Custom myPageWithComboState



Function .onInit
StrCpy $CheckboxState ${BST_CHECKED} ; Set the initial state. This is optional but useful if you use $CheckboxState in a section when the installer is silent
FunctionEnd

Function myPageWithCombobox
nsDialogs::Create 1018
Pop $0

${NSD_CreateCheckbox} 80 203 100% 10u $(DrivePage_Text2)
Pop $hwndCheckbox
${NSD_SetState} $hwndCheckbox $CheckboxState ; Reuse the existing state so it is correct when the back button is used

nsDialogs::Show
FunctionEnd

Function myPageWithComboboxLeaveCallback
${NSD_GetState} $hwndCheckbox $CheckboxState ; Save the state so we can retrieve it on the next page
FunctionEnd



Function myPageWithComboState
nsDialogs::Create 1018
Pop $0

${NSD_CreateLabel} 0 0 100% 160 CheckboxState=$CheckboxState
