如何在NSIS中创建sectiongroup所需的section？

我想在sectiongroup中创建一个section，该section group需要该section group，但如果未选中该group，则整个安装不需要该section。我尝试过“SectionIn R0”，但这使得整个安装都需要该部分，我只希望在他们选择组本身时需要该部分

SectionGroup "group"
  Section "required for section group"
    SectionIn RO
  SectionEnd

  Section "optional"
  SectionEnd
SectionGroupEnd

---

您不能仅使用属性来执行此操作，您需要一些实际的代码：

!include Sections.nsh
!include LogicLib.nsh

SectionGroup /e "group"
  Section "required for section group" SEC_REQ
    SectionIn RO
  SectionEnd
  Section "optional" SEC_OPT
  SectionEnd
SectionGroupEnd

Function .onSelChange
${If} ${SectionIsSelected} ${SEC_OPT}
    !define /math MYSECTIONFLAGS ${SF_SELECTED} | ${SF_RO}
    !insertmacro SetSectionFlag ${SEC_REQ} ${MYSECTIONFLAGS} 
    !undef MYSECTIONFLAGS
${Else}
    !insertmacro ClearSectionFlag ${SEC_REQ} ${SF_RO}
${EndIf}
FunctionEnd

请注意，取消选中节组本身时存在一个“bug”，要解决这个问题，您需要保持一些全局状态，因为nsis不会告诉您哪个节生成了通知。以下代码具有更好的逻辑：

!include Sections.nsh
!include LogicLib.nsh

SectionGroup /e "group" SEC_GRP
  Section "required for section group" SEC_REQ
    SectionIn RO
  SectionEnd
  Section "optional" SEC_OPT
  SectionEnd
  Section "" PRIVSEC_TOGGLESTATE ;hidden section to keep track of state
  SectionEnd
SectionGroupEnd

Function .onSelChange
!define /math SECFLAGS_SELRO ${SF_SELECTED} | ${SF_RO}
${IfNot} ${SectionIsSelected} ${PRIVSEC_TOGGLESTATE}
${AndIf} ${SectionIsReadOnly} ${SEC_REQ}
    !insertmacro ClearSectionFlag ${SEC_REQ} ${SECFLAGS_SELRO}
${EndIf}
${If} ${SectionIsSelected} ${SEC_OPT}
    !insertmacro SetSectionFlag ${SEC_REQ} ${SECFLAGS_SELRO} 
${Else}
    !insertmacro ClearSectionFlag ${SEC_REQ} ${SF_RO}
${EndIf}
${If} ${SectionIsSelected} ${SEC_REQ}
    !insertmacro SelectSection ${PRIVSEC_TOGGLESTATE}
${Else}
    !insertmacro UnselectSection ${PRIVSEC_TOGGLESTATE}
${EndIf}
!undef SECFLAGS_SELRO
FunctionEnd

还可以使用SectionSetFlags命令将这些节设置为强制节。只需将其添加到.onInit函数中，如下所示：

SectionGroup "group" Sec01
  Section "required for section group"
  SectionIn RO
  SectionEnd

  Section "optional" Sec02
  SectionEnd
SectionGroupEnd

Function .onInit
  SectionSetFlags ${Sec01} 17
FunctionEnd

这将灰显“组”，但它将按预期进行选择和安装。

您也可以使用SectionSetFlags命令将这些节设置为必填节。只需将其添加到.onInit函数中，如下所示：

SectionGroup "group" Sec01
  Section "required for section group"
  SectionIn RO
  SectionEnd

  Section "optional" Sec02
  SectionEnd
SectionGroupEnd

Function .onInit
  SectionSetFlags ${Sec01} 17

比公认的答案简单得多。然而，我认为这是一个错误，你有“Sec01”两次。很好发现-我修正了它。比公认的答案简单得多。然而，我认为这是一个错误，你有“Sec01”两次。很好的发现-我修复了它。
