如果选择了某个组件,我想提示用户提供额外信息,但我不确定如何检查是否选择了给定组件。似乎http://nsis.sourceforge.net/Docs/Chapter4.html#4.9.13.2可能有某种相关性,但我的印象是一个部分是一组组件......
在安德斯的帮助下,我有这个工作:
!include MUI.nsh
!include nsDialogs.nsh
!include LogicLib.nsh
!include sections.nsh
Name A
InstProgressFlags smooth colored
LicenseBkColor /windows
OutFile A.exe
InstallDir $PROGRAMFILES\A
Var Dialog
Section "A" SEC_A
SectionEnd
Section "B" SEC_B
SectionEnd
!insertmacro MUI_PAGE_COMPONENTS
Page custom getA setA # {{{
!insertmacro MUI_PAGE_DIRECTORY # {{{ install
Function getA
${Unless} ${SectionIsSelected} ${SEC_A}
Abort
${EndUnless}
nsDialogs::Create 1018
Pop $Dialog
${If} $Dialog == error
Abort
${EndIf}
${NSD_CreateLabel} 0 0 100% 12u "Test"
nsDialogs::Show
FunctionEnd
Function setA
MessageBox MB_OK "clicked?"
FunctionEnd
# }}}
!insertmacro MUI_PAGE_INSTFILES
!insertmacro MUI_UNPAGE_CONFIRM
!insertmacro MUI_UNPAGE_INSTFILES
