无法理解为什么 ${NSD_GetState} $Checkbox 不起作用

Question

谁能给我解释一下，为什么 ${NSD_GetState} $Checkbox 不起作用？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。

其实我是第一次尝试做一个nsis安装器，所以我什至不知道应该在哪里找错误或者我只是不明白这门语言的逻辑。

你的例子中有太多不相关的代码，有点难以理解你真正想做什么。

如果您想在另一个页面上检索复选框的状态，则必须保存该状态，因为当您离开该页面时，复选框控件会被销毁。

!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 [=10=]

${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 [=10=]

${NSD_CreateLabel} 0 0 100% 160 CheckboxState=$CheckboxState
Pop [=10=]

nsDialogs::Show
FunctionEnd
