NSIS：组件检查事件上的组件页面

Question

我使用 NSIS 安装我的项目。当我选择要在组件页面上安装的部分时，我需要显示带有警告文本的 MessageBox。有什么方法可以跟踪复选框上的点击，可能是事件还是什么？

Answer 1

在 NSIS 3 中，更改的部分 ID 存储在 $0:

Page Components
Page InstFiles

Section /o "Foo" SID_FOO
SectionEnd

Section "Bar"
SectionEnd

!include LogicLib.nsh

Function .onSelChange
${If} ${SectionIsSelected} ${SID_FOO}
${AndIf} [=10=] = ${SID_FOO}
    MessageBox MB_ICONEXCLAMATION "Warning, section Foo selected!"
${EndIf}
FunctionEnd

您必须自己在 NSIS 2 中跟踪状态：

Page Components
Page InstFiles

Section /o "Foo" SID_FOO
SectionEnd

Section "Bar"
SectionEnd

!include LogicLib.nsh

Var hasWarned

Function .onSelChange
${If} ${SectionIsSelected} ${SID_FOO}
${AndIf} $hasWarned = 0
    StrCpy $hasWarned 1
    MessageBox MB_ICONEXCLAMATION "Warning, section Foo selected!"
${EndIf}
/* Uncomment this to display the warning every time it is selected
${IfNot} ${SectionIsSelected} ${SID_FOO}
    StrCpy $hasWarned 0
${EndIf}
*/
FunctionEnd
